+Mount Options
+=============
+
+Parsing options
+---------------
+
+On mount and remount the filesystem is passed a string containing a
+comma separated list of mount options. The options can have either of
+these forms:
+
+ option
+ option=value
+
+The <linux/parser.h> header defines an API that helps parse these
+options. There are plenty of examples on how to use it in existing
+filesystems.
+
+Showing options
+---------------
+
+If a filesystem accepts mount options, it must define show_options()
+to show all the currently active options. The rules are:
+
+ - options MUST be shown which are not default or their values differ
+ from the default
+
+ - options MAY be shown which are enabled by default or have their
+ default value
+
+Options used only internally between a mount helper and the kernel
+(such as file descriptors), or which only have an effect during the
+mounting (such as ones controlling the creation of a journal) are exempt
+from the above rules.
+
+The underlying reason for the above rules is to make sure, that a
+mount can be accurately replicated (e.g. umounting and mounting again)
+based on the information found in /proc/mounts.
+
+A simple method of saving options at mount/remount time and showing
+them is provided with the save_mount_options() and
+generic_show_options() helper functions. Please note, that using
+these may have drawbacks. For more info see header comments for these
+functions in fs/namespace.c.

+ =========================
+ MN10300 FUNCTION CALL ABI
+ =========================
+
+=======
+GENERAL
+=======
+
+The MN10300/AM33 kernel runs in little-endian mode; big-endian mode is not
+supported.
+
+The stack grows downwards, and should always be 32-bit aligned. There are
+separate stack pointer registers for userspace and the kernel.
+
+
+================
+ARGUMENT PASSING
+================
+
+The first two arguments (assuming up to 32-bits per argument) to a function are
+passed in the D0 and D1 registers respectively; all other arguments are passed
+on the stack.
+
+If 64-bit arguments are being passed, then they are never split between
+registers and the stack. If the first argument is a 64-bit value, it will be
+passed in D0:D1. If the first argument is not a 64-bit value, but the second
+is, the second will be passed entirely on the stack and D1 will be unused.
+
+Arguments smaller than 32-bits are not coelesced within a register or a stack
+word. For example, two byte-sized arguments will always be passed in separate
+registers or word-sized stack slots.
+
+
+=================
+CALLING FUNCTIONS
+=================
+
+The caller must allocate twelve bytes on the stack for the callee's use before
+it inserts a CALL instruction. The CALL instruction will write into the TOS
+word, but won't actually modify the stack pointer; similarly, the RET
+instruction reads from the TOS word of the stack, but doesn't move the stack
+pointer beyond it.
+
+
+ Stack:
+ | |
+ | |
+ |---------------| SP+20
+ | 4th Arg |
+ |---------------| SP+16
+ | 3rd Arg |
+ |---------------| SP+12
+ | D1 Save Slot |
+ |---------------| SP+8
+ | D0 Save Slot |
+ |---------------| SP+4
+ | Return Addr |
+ |---------------| SP
+ | |
+ | |
+
+
+The caller must leave space on the stack (hence an allocation of twelve bytes)
+in which the callee may store the first two arguments.
+
+
+============
+RETURN VALUE
+============
+
+The return value is passed in D0 for an integer (or D0:D1 for a 64-bit value),
+or A0 for a pointer.
+
+If the return value is a value larger than 64-bits, or is a structure or an
+array, then a hidden first argument will be passed to the callee by the caller:
+this will point to a piece of memory large enough to hold the result of the
+function. In this case, the callee will return the value in that piece of
+memory, and no value will be returned in D0 or A0.
+
+
+===================
+REGISTER CLOBBERING
+===================
+
+The values in certain registers may be clobbered by the callee, and other
+values must be saved:
+
+ Clobber: D0-D1, A0-A1, E0-E3
+ Save: D2-D3, A2-A3, E4-E7, SP
+
+All other non-supervisor-only registers are clobberable (such as MDR, MCRL,
+MCRH).
+
+
+=================
+SPECIAL REGISTERS
+=================
+
+Certain ordinary registers may carry special usage for the compiler:
+
+ A3: Frame pointer
+ E2: TLS pointer
+
+
+==========
+KERNEL ABI
+==========
+
+The kernel may use a slightly different ABI internally.
+
+ (*) E2
+
+ If CONFIG_MN10300_CURRENT_IN_E2 is defined, then the current task pointer
+ will be kept in the E2 register, and that register will be marked
+ unavailable for the compiler to use as a scratch register.
+
+ Normally the kernel uses something like:
+
+ MOV SP,An
+ AND 0xFFFFE000,An
+ MOV (An),Rm // Rm holds current
+ MOV (yyy,Rm) // Access current->yyy
+
+ To find the address of current; but since this option permits current to
+ be carried globally in an register, it can use:
+
+ MOV (yyy,E2) // Access current->yyy
+
+ instead.
+
+
+===============
+SYSTEM CALL ABI
+===============
+
+System calls are called with the following convention:
+
+ REGISTER ENTRY EXIT
+ =============== ======================= =======================
+ D0 Syscall number Return value
+ A0 1st syscall argument Saved
+ D1 2nd syscall argument Saved
+ A3 3rd syscall argument Saved
+ A2 4th syscall argument Saved
+ D3 5th syscall argument Saved
+ D2 6th syscall argument Saved
+
+All other registers are saved. The layout is a consequence of the way the MOVM
+instruction stores registers onto the stack.

+ PART-SPECIFIC SOURCE COMPARTMENTALISATION
+ =========================================
+
+The sources for various parts are compartmentalised at two different levels:
+
+ (1) Processor level
+
+ The "processor level" is a CPU core plus the other on-silicon
+ peripherals.
+
+ Processor-specific header files are divided among directories in a similar
+ way to the CPU level:
+
+ (*) include/asm-mn10300/proc-mn103e010/
+
+ Support for the AM33v2 CPU core.
+
+ The appropriate processor is selected by a CONFIG_MN10300_PROC_YYYY option
+ from the "Processor support" choice menu in the arch/mn10300/Kconfig file.
+
+
+ (2) Unit level
+
+ The "unit level" is a processor plus all the external peripherals
+ controlled by that processor.
+
+ Unit-specific header files are divided among directories in a similar way
+ to the CPU level; not only that, but specific sources may also be
+ segregated into separate directories under the arch directory:
+
+ (*) include/asm-mn10300/unit-asb2303/
+ (*) arch/mn10300/unit-asb2303/
+
+ Support for the ASB2303 board with an ASB2308 daughter board.

+ (*) arch/mn10300/unit-asb2305/
+
+ Support for the ASB2305 board.
+
+ The appropriate processor is selected by a CONFIG_MN10300_UNIT_ZZZZ option
+ from the "Unit type" choice menu in the arch/mn10300/Kconfig file.
+
+
+============
+COMPILE TIME
+============
+
+When the kernel is compiled, symbolic links will be made in the asm header file
+directory for this arch:
+
+ include/asm-mn10300/proc => include/asm-mn10300/proc-YYYY/
+ include/asm-mn10300/unit => include/asm-mn10300/unit-ZZZZ/
+
+So that the header files contained in those directories can be accessed without
+lots of #ifdef-age.
+
+The appropriate arch/mn10300/unit-ZZZZ directory will also be entered by the
+compilation process; all other unit-specific directories will be ignored.

- * Cosmetic change to printouts.
- *
- * Revision 1.25 2002/08/21 08:15:42 jonashg
- * Made it compile even without CONFIG_MTD_CONCAT defined.
- *
- * Revision 1.24 2002/08/20 13:12:35 jonashg
- * * New approach to probing. Probe cse0 and cse1 separately and (mtd)concat
- * the results.
- * * Removed compile time tests concerning how the mtdram driver has been
- * configured. The user will know about the misconfiguration at runtime
- * instead. (The old approach made it impossible to use mtdram for anything
- * else than RAM boot).
- *
- * Revision 1.23 2002/05/13 12:12:28 johana

- * Changed comment about cached access since we changed this before
- *
- * Revision 1.18 2002/03/05 17:06:15 jonashg
- * Try amd_flash probe before cfi_probe since amd_flash driver can handle two
- * (or more) flash chips of different model and the cfi driver cannot.

- *
- * Revision 1.16 2001/11/08 11:18:58 jonashg

- * CONFIG_ETRAX_PTABLE_SECTOR.
- *
- * Revision 1.10 2001/05/29 09:42:03 jonashg
- * Use macro for end marker length instead of sizeof.
- *
- * Revision 1.9 2001/05/29 08:52:52 jonashg
- * Gave names to the magic fours (size of the ptable end marker).
- *
- * Revision 1.8 2001/05/28 15:36:20 jonashg
- * * Removed old comment about ptable location in flash (it's a CONFIG_ option).
- * * Variable ptable was initialized twice to the same value.

- * Revision 1.14 2002/04/12 12:01:53 johana
- * Use global r_port_g_data_shadow.
- * Moved gpio_init_port_g() closer to gpio_init() and marked it __init.
- *
- * Revision 1.13 2002/04/10 12:03:55 johana
- * Added support for port G /dev/gpiog (minor 3).
- * Changed indentation on switch cases.
- * Fixed other spaces to tabs.
- *
- * Revision 1.12 2001/11/12 19:42:15 pkj
- * * Corrected return values from gpio_leds_ioctl().

- * bittoggling in the kernel. (This speeds up programming an FPGA with 450kB
- * from ~60 seconds to 4 seconds).
- * Added save_flags/cli/restore_flags in ioctl.

- * Include config.h now that we use some CONFIG_ options
- *
- * Revision 1.25 2001/05/15 05:38:47 hp
- * Tweaked code in _ret_from_sys_call

- *
- * Revision 1.17 2001/03/21 16:12:55 bjornw
- * * Always make room for the cpu status record in the frame, in order to
- * use the same framelength and layout for both mmu busfaults and normal
- * irqs. No need to check for the explicit CRIS_FRAME_FIXUP type anymore.
- * * Fixed bug with using addq for popping the stack in the epilogue - it

- * - (_system_call): Don't use r10 and don't save and restore it.
- * - (THREAD_ESP0): New constant.
- * - (_system_call): Inline set_esp0.
- *
- * Revision 1.12 2001/01/31 17:56:25 orjanf
- * Added definition of LTASK_PID and made it global.
- *
- * Revision 1.11 2001/01/10 21:13:29 bjornw

- * Added detection of frame-type in Rexit, so that mmu_bus_fault can
- * use ret_from_intr in the return-path to check for signals (like SEGV)

- *
- * Revision 1.7 2000/10/06 15:04:28 bjornw

- *
- * Revision 1.4 2000/08/02 13:59:30 bjornw

- * Revision 1.10 2004/12/07 09:19:38 starvik
- * Corrected includes.
- * Use correct interrupt macros.
- *
- * Revision 1.9 2004/05/14 10:18:58 starvik
- * Export fast_timer_list

- * Merge of Linux 2.5.74
- *

- * New INTR_VECT macros.
- *
- * Revision 1.4 2003/06/03 08:49:45 johana
- * Fixed typo.
- *
- * Revision 1.3 2003/06/02 12:51:27 johana
- * Now compiles.
- * Commented some include files that probably can be removed.
- *
- * Revision 1.2 2003/06/02 12:09:41 johana
- * Ported to ETRAX FS using the trig interrupt instead of timer1.
- *
- * Revision 1.3 2002/12/12 08:26:32 starvik
- * Don't use C-comments inside CVS comments
- *
- * Revision 1.2 2002/12/11 15:42:02 starvik
- * Extracted v10 (ETRAX 100LX) specific stuff from arch/cris/kernel/
- *
- * Revision 1.1 2002/11/18 07:58:06 starvik
- * Fast timers (from Linux 2.4)
- *
- * Revision 1.5 2002/10/15 06:21:39 starvik
- * Added call to init_waitqueue_head
- *
- * Revision 1.4 2002/05/28 17:47:59 johana
- * Added del_fast_timer()
- *
- * Revision 1.3 2002/05/28 16:16:07 johana
- * Handle empty fast_timer_list
- *
- * Revision 1.2 2002/05/27 15:38:42 johana
- * Made it compile without warnings on Linux 2.4.
- * (includes, wait_queue, PROC_FS and snprintf)
- *
- * Revision 1.1 2002/05/27 15:32:25 johana
- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
- *
- * Revision 1.8 2001/11/27 13:50:40 pkj
- * Disable interrupts while stopping the timer and while modifying the
- * list of active timers in timer1_handler() as it may be interrupted
- * by other interrupts (e.g., the serial interrupt) which may add fast
- * timers.
- *
- * Revision 1.7 2001/11/22 11:50:32 pkj
- * * Only store information about the last 16 timers.
- * * proc_fasttimer_read() now uses an allocated buffer, since it
- * requires more space than just a page even for only writing the
- * last 16 timers. The buffer is only allocated on request, so
- * unless /proc/fasttimer is read, it is never allocated.
- * * Renamed fast_timer_started to fast_timers_started to match
- * fast_timers_added and fast_timers_expired.
- * * Some clean-up.
- *
- * Revision 1.6 2000/12/13 14:02:08 johana
- * Removed volatile for fast_timer_list
- *
- * Revision 1.5 2000/12/13 13:55:35 johana
- * Added DEBUG_LOG, added som cli() and cleanup
- *
- * Revision 1.4 2000/12/05 13:48:50 johana
- * Added range check when writing proc file, modified timer int handling
- *
- * Revision 1.3 2000/11/23 10:10:20 johana
- * More debug/logging possibilities.
- * Moved GET_JIFFIES_USEC() to timex.h and time.c
- *
- * Revision 1.2 2000/11/01 13:41:04 johana
- * Clean up and bugfixes.
- * Created new do_gettimeofday_fast() that gets a timeval struct
- * with time based on jiffies and *R_TIMER0_DATA, uses a table
- * for fast conversion of timer value to microseconds.
- * (Much faster the standard do_gettimeofday() and we don't really
- * want to use the true time - we want the "uptime" so timers don't screw up
- * when we change the time.
- * TODO: Add efficient support for continuous timers as well.
- *
- * Revision 1.1 2000/10/26 15:49:16 johana
- * Added fasttimer, highresolution timers.

- * Re-added the change of frametype when handling kernel page fault fixup
- * for v10. This is necessary to avoid that the CPU remakes the faulting
- * access.
- *
- * Revision 1.17 2005/01/11 13:53:05 starvik
- * Use raw_printk.
- *
- * Revision 1.16 2004/12/17 11:39:41 starvik
- * SMP support.
- *
- * Revision 1.15 2004/11/23 18:36:18 starvik
- * Stack is now non-executable.
- * Signal handler trampolines are placed in a reserved page mapped into all
- * processes.
- *
- * Revision 1.14 2004/11/23 07:10:21 starvik
- * Moved find_fixup_code to generic code.
- *
- * Revision 1.13 2004/11/23 07:00:54 starvik
- * Actually use the execute permission bit in the MMU. This makes it possible
- * to prevent e.g. attacks where executable code is put on the stack.
- *
- * Revision 1.12 2004/09/29 06:16:04 starvik
- * Use instruction_pointer
- *
- * Revision 1.11 2004/05/14 07:58:05 starvik
- * Merge of changes from 2.4
- *
- * Revision 1.10 2003/10/27 14:51:24 starvik
- * Removed debugcode

- * Changed do_page_fault signature
- *
- * Revision 1.8 2003/07/04 13:02:48 tobiasa
- * Moved code snippet from arch/cris/mm/fault.c that searches for fixup code
- * to separate function in arch-specific files.
- *
- * Revision 1.7 2003/01/22 06:48:38 starvik
- * Fixed warnings issued by GCC 3.2.1
- *
- * Revision 1.6 2003/01/09 14:42:52 starvik
- * Merge of Linux 2.5.55
- *
- * Revision 1.5 2002/12/11 14:44:48 starvik
- * Extracted v10 (ETRAX 100LX) specific stuff to arch/cris/arch-v10/mm
- *
- * Revision 1.4 2002/11/13 15:10:28 starvik
- * pte_offset has been renamed to pte_offset_kernel
- *
- * Revision 1.3 2002/11/05 06:45:13 starvik
- * Merge of Linux 2.5.45
- *
- * Revision 1.2 2001/12/18 13:35:22 bjornw
- * Applied the 2.4.13->2.4.16 CRIS patch to 2.5.1 (is a copy of 2.4.15).
- *
- * Revision 1.20 2001/11/22 13:34:06 bjornw
- * * Bug workaround (LX TR89): force a rerun of the whole of an interrupted
- * unaligned write, because the second half of the write will be corrupted
- * otherwise. Affected unaligned writes spanning not-yet mapped pages.
- * * Optimization: use the wr_rd bit in R_MMU_CAUSE to know whether a miss
- * was due to a read or a write (before we didn't know this until the next
- * restart of the interrupted instruction, thus wasting one fault-irq)
- *
- * Revision 1.19 2001/11/12 19:02:10 pkj
- * Fixed compiler warnings.
- *
- * Revision 1.18 2001/07/18 22:14:32 bjornw
- * Enable interrupts in the bulk of do_page_fault
- *
- * Revision 1.17 2001/07/18 13:07:23 bjornw
- * * Detect non-existant PTE's in vmalloc pmd synchronization
- * * Remove comment about fast-paths for VMALLOC_START etc, because all that
- * was totally bogus anyway it turned out :)
- * * Fix detection of vmalloc-area synchronization
- * * Add some comments
- *
- * Revision 1.16 2001/06/13 00:06:08 bjornw
- * current_pgd should be volatile
- *
- * Revision 1.15 2001/06/13 00:02:23 bjornw
- * Use a separate variable to store the current pgd to avoid races in schedule
- *
- * Revision 1.14 2001/05/16 17:41:07 hp
- * Last comment tweak further tweaked.
- *
- * Revision 1.13 2001/05/15 00:58:44 hp
- * Expand a bit on the comment why we compare address >= TASK_SIZE rather
- * than >= VMALLOC_START.
- *
- * Revision 1.12 2001/04/04 10:51:14 bjornw
- * mmap_sem is grabbed for reading
- *
- * Revision 1.11 2001/03/23 07:36:07 starvik
- * Corrected according to review remarks
- *
- * Revision 1.10 2001/03/21 16:10:11 bjornw
- * CRIS_FRAME_FIXUP not needed anymore, use FRAME_NORMAL
- *
- * Revision 1.9 2001/03/05 13:22:20 bjornw
- * Spell-fix and fix in vmalloc_fault handling

- * flash during CRIS_LOW_MAP from 0xe to 0x8 so both the flash and the I/O
- * is mapped straight over (for !CRIS_LOW_MAP the uncached flash is still 0xe)
- *
- * Revision 1.17 2001/02/22 15:05:21 bjornw
- * Map 0x9 straight over during LOW_MAP to allow for memory mapped LEDs
- *
- * Revision 1.16 2001/02/22 15:02:35 bjornw
- * Map 0xc straight over during LOW_MAP to allow for memory mapped I/O
- *
- * Revision 1.15 2001/01/10 21:12:10 bjornw
- * loops_per_sec -> loops_per_jiffy
- *
- * Revision 1.14 2000/11/22 16:23:20 bjornw
- * Initialize totalhigh counters to 0 to make /proc/meminfo look nice.
- *
- * Revision 1.13 2000/11/21 16:37:51 bjornw
- * Temporarily disable initmem freeing
- *
- * Revision 1.12 2000/11/21 13:55:07 bjornw
- * Use CONFIG_CRIS_LOW_MAP for the low VM map instead of explicit CPU type
- *
- * Revision 1.11 2000/10/06 12:38:22 bjornw
- * Cast empty_bad_page correctly (should really be of * type from the start..
- *
- * Revision 1.10 2000/10/04 16:53:57 bjornw
- * Fix memory-map due to LX features
- *
- * Revision 1.9 2000/09/13 15:47:49 bjornw
- * Wrong count in reserved-pages loop
- *
- * Revision 1.8 2000/09/13 14:35:10 bjornw
- * 2.4.0-test8 added a new arg to free_area_init_node
- *
- * Revision 1.7 2000/08/17 15:35:55 bjornw

+ is filled and a cacheline needs to be displaced from the cache to
+ make room. Only at that point is it written back.

+ cacheline is also in cache, it will be updated too.

+ * To enable debugger support, two things need to happen. One, a
+ * call to set_debug_traps() is necessary in order to allow any breakpoints
+ * or error conditions to be properly intercepted and reported to gdb.
+ * Two, a breakpoint needs to be generated to begin communication. This
+ * is most easily accomplished by a call to breakpoint(). Breakpoint()
+ * simulates a breakpoint by executing a BREAK instruction.
+ *
+ *
+ * The following gdb commands are supported:
+ *
+ * command function Return value
+ *
+ * g return the value of the CPU registers hex data or ENN
+ * G set the value of the CPU registers OK or ENN
+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
+ * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
+ *
+ * c Resume at current address SNN ( signal NN)
+ * cAA..AA Continue at address AA..AA SNN
+ *
+ * s Step one instruction SNN
+ * sAA..AA Step one instruction from AA..AA SNN
+ *
+ * k kill
+ *
+ * ? What was the last sigval ? SNN (signal NN)
+ *
+ * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
+ * baud rate
+ *
+ * All commands and responses are sent with a packet which includes a
+ * checksum. A packet consists of
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer. '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host: Reply:
+ * $m0,10#2a +$00010203040506070809101112131415#42
+ *
+ *
+ * ==============
+ * MORE EXAMPLES:
+ * ==============
+ *
+ * For reference -- the following are the steps that one
+ * company took (RidgeRun Inc) to get remote gdb debugging
+ * going. In this scenario the host machine was a PC and the
+ * target platform was a Galileo EVB64120A MIPS evaluation
+ * board.
+ *
+ * Step 1:
+ * First download gdb-5.0.tar.gz from the internet.
+ * and then build/install the package.
+ *
+ * Example:
+ * $ tar zxf gdb-5.0.tar.gz
+ * $ cd gdb-5.0
+ * $ ./configure --target=am33_2.0-linux-gnu
+ * $ make
+ * $ install
+ * am33_2.0-linux-gnu-gdb
+ *
+ * Step 2:
+ * Configure linux for remote debugging and build it.
+ *
+ * Example:
+ * $ cd ~/linux
+ * $ make menuconfig <go to "Kernel Hacking" and turn on remote debugging>
+ * $ make dep; make vmlinux
+ *
+ * Step 3:
+ * Download the kernel to the remote target and start
+ * the kernel running. It will promptly halt and wait
+ * for the host gdb session to connect. It does this
+ * since the "Kernel Hacking" option has defined
+ * CONFIG_REMOTE_DEBUG which in turn enables your calls
+ * to:
+ * set_debug_traps();
+ * breakpoint();
+ *
+ * Step 4:
+ * Start the gdb session on the host.
+ *
+ * Example:
+ * $ am33_2.0-linux-gnu-gdb vmlinux
+ * (gdb) set remotebaud 115200
+ * (gdb) target remote /dev/ttyS1
+ * ...at this point you are connected to
+ * the remote target and can use gdb
+ * in the normal fasion. Setting
+ * breakpoints, single stepping,
+ * printing variables, etc.

+ *
+ * Our solution:
+ * (1) Allocate resources for all buses behind PCI-to-PCI bridges.
+ * This gives us fixed barriers on where we can allocate.
+ * (2) Allocate resources for all enabled devices. If there is
+ * a collision, just mark the resource as unallocated. Also

+ * (3) Try to allocate resources for disabled devices. If the
+ * resources were assigned correctly, everything goes well,
+ * if they weren't, they won't disturb allocation of other
+ * resources.
+ * (4) Assign new addresses to resources which were either
+ * not configured at all or misconfigured. If explicitly

- This is needed when the host kernel on which you run has a non-default
- (like 2G/2G) memory split, instead of the customary 3G/1G. If you did
- not recompile your own kernel but use the default distro's one, you can
- safely accept the "Default split" option.
-
- It can be enabled on recent (>=2.6.16-rc2) vanilla kernels via
- CONFIG_VM_SPLIT_*, or on previous kernels with special patches (-ck
- patchset by Con Kolivas, or other ones) - option names match closely the
- host CONFIG_VM_SPLIT_* ones.
-
- A lower setting (where 1G/3G is lowest and 3G/1G is higher) will
- tolerate even more "normal" host kernels, but an higher setting will be
- stricter.
-
- So, if you do not know what to do here, say 'Default split'.

- * ramdisk.c - Multiple RAM disk driver - gzip-loading version - v. 0.8 beta.
- *
- * (C) Chad Page, Theodore Ts'o, et. al, 1995.
- *
- * This RAM disk is designed to have filesystems created on it and mounted
- * just like a regular floppy disk.
- *
- * It also does something suggested by Linus: use the buffer cache as the
- * RAM disk data. This makes it possible to dynamically allocate the RAM disk
- * buffer - with some consequences I have to deal with as I write this.
- *
- * This code is based on the original ramdisk.c, written mostly by
- * Theodore Ts'o (TYT) in 1991. The code was largely rewritten by
- * Chad Page to use the buffer cache to store the RAM disk data in
- * 1995; Theodore then took over the driver again, and cleaned it up
- * for inclusion in the mainline kernel.
- *
- * The original CRAMDISK code was written by Richard Lyons, and
- * adapted by Chad Page to use the new RAM disk interface. Theodore
- * Ts'o rewrote it so that both the compressed RAM disk loader and the
- * kernel decompressor uses the same inflate.c codebase. The RAM disk
- * loader now also loads into a dynamic (buffer cache based) RAM disk,
- * not the old static RAM disk. Support for the old static RAM disk has
- * been completely removed.
- *
- * Loadable module support added by Tom Dyas.
- *
- * Further cleanups by Chad Page (page0588@sundance.sjsu.edu):
- * Cosmetic changes in #ifdef MODULE, code movement, etc.
- * When the RAM disk module is removed, free the protected buffers
- * Default RAM disk size changed to 2.88 MB
- *
- * Added initrd: Werner Almesberger & Hans Lermen, Feb '96
- *
- * 4/25/96 : Made RAM disk size a parameter (default is now 4 MB)
- * - Chad Page
- *
- * Add support for fs images split across >1 disk, Paul Gortmaker, Mar '98
- *
- * Make block size and block size shift for RAM disks a global macro
- * and set blk_size for -ENOSPC, Werner Fink <werner@suse.de>, Apr '99

+ * It is currently not believed that long longs are common, so we
+ * trade efficiency for the chars, shorts and longs against the long
+ * longs.
+ *
+ * Current stats with gcc 2.7.2.2 for these functions:
+ *
+ * ptrsize get: code regs put: code regs
+ * 1 1 1 1 2
+ * 2 3 2 3 2
+ * 4 7 3 7 3
+ * 8 20 6 16 6

+ * gcc 2.95.1 seems to code differently:
+ *
+ * ptrsize get: code regs put: code regs
+ * 1 1 1 1 2
+ * 2 3 2 3 2
+ * 4 7 4 7 4
+ * 8 19 8 15 6
+ *
+ * which may or may not be more efficient (depending upon whether
+ * you can afford the extra registers). Hopefully the gcc 2.95
+ * is inteligent enough to decide if it is better to use the
+ * extra register, but evidence so far seems to suggest otherwise.
+ *
