+ Getting Coccinelle
+~~~~~~~~~~~~~~~~~~~~
+
+The semantic patches included in the kernel use the 'virtual rule'
+feature which was introduced in Coccinelle version 0.1.11.
+
+Coccinelle (>=0.2.0) is available through the package manager
+of many distributions, e.g. :
+
+ - Debian (>=squeeze)
+ - Fedora (>=13)
+ - Ubuntu (>=10.04 Lucid Lynx)
+ - OpenSUSE
+ - Arch Linux
+ - NetBSD
+ - FreeBSD
+
+
+You can get the latest version released from the Coccinelle homepage at
+http://coccinelle.lip6.fr/
+
+Once you have it, run the following command:
+
+ ./configure
+ make
+
+as a regular user, and install it with
+
+ sudo make install
+
+
+ Using Coccinelle on the Linux kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A Coccinelle-specific target is defined in the top level
+Makefile. This target is named 'coccicheck' and calls the 'coccicheck'
+front-end in the 'scripts' directory.
+
+Four modes are defined: report, patch, context, and org. The mode to
+use is specified by setting the MODE variable with 'MODE=<mode>'.
+
+'report' generates a list in the following format:
+ file:line:column-column: message
+
+'patch' proposes a fix, when possible.
+
+'context' highlights lines of interest and their context in a
+diff-like style.Lines of interest are indicated with '-'.
+
+'org' generates a report in the Org mode format of Emacs.
+
+Note that not all semantic patches implement all modes.
+
+To make a report for every semantic patch, run the following command:
+
+ make coccicheck MODE=report
+
+NB: The 'report' mode is the default one.
+
+To produce patches, run:
+
+ make coccicheck MODE=patch
+
+
+The coccicheck target applies every semantic patch available in the
+subdirectories of 'scripts/coccinelle' to the entire Linux kernel.
+
+For each semantic patch, a changelog message is proposed. It gives a
+description of the problem being checked by the semantic patch, and
+includes a reference to Coccinelle.
+
+As any static code analyzer, Coccinelle produces false
+positives. Thus, reports must be carefully checked, and patches
+reviewed.
+
+
+ Using Coccinelle with a single semantic patch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The optional make variable COCCI can be used to check a single
+semantic patch. In that case, the variable must be initialized with
+the name of the semantic patch to apply.
+
+For instance:
+
+ make coccicheck COCCI=<my_SP.cocci> MODE=patch
+or
+ make coccicheck COCCI=<my_SP.cocci> MODE=report
+
+
+ Proposing new semantic patches
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New semantic patches can be proposed and submitted by kernel
+developers. For sake of clarity, they should be organized in the
+subdirectories of 'scripts/coccinelle/'.
+
+
+ Detailed description of the 'report' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+'report' generates a list in the following format:
+ file:line:column-column: message
+
+Example:
+
+Running
+
+ make coccicheck MODE=report COCCI=scripts/coccinelle/err_cast.cocci
+
+will execute the following part of the SmPL script.
+

+
+
+ Detailed description of the 'patch' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When the 'patch' mode is available, it proposes a fix for each problem
+identified.
+
+Example:
+
+Running
+ make coccicheck MODE=patch COCCI=scripts/coccinelle/err_cast.cocci

+ Hardware driver for OCTEON's on chip watchdog timer.
+ Enables the watchdog for all cores running Linux. It
+ installs a NMI handler and pokes the watchdog based on an
+ interrupt. On first expiration of the watchdog, the
+ interrupt handler pokes it. The second expiration causes an
+ NMI that prints a message. The third expiration causes a
+ global soft reset.
+
+ When userspace has /dev/watchdog open, no poking is done
+ from the first interrupt, it is then only poked when the
+ device is written.

+ * The OCTEON watchdog has a maximum timeout of 2^32 * io_clock.
+ * For most systems this is less than 10 seconds, so to allow for
+ * software to request longer watchdog heartbeats, we maintain software
+ * counters to count multiples of the base rate. If the system locks
+ * up in such a manner that we can not run the software counters, the
+ * only result is a watchdog reset sooner than was requested. But
+ * that is OK, because in this case userspace would likely not be able
+ * to do anything anyhow.
+ *
+ * The hardware watchdog interval we call the period. The OCTEON
+ * watchdog goes through several stages, after the first period an
+ * irq is asserted, then if it is not reset, after the next period NMI
+ * is asserted, then after an additional period a chip wide soft reset.
+ * So for the software counters, we reset watchdog after each period
+ * and decrement the counter. But for the last two periods we need to
+ * let the watchdog progress to the NMI stage so we disable the irq
+ * and let it proceed. Once in the NMI, we print the register state
+ * to the serial port and then wait for the reset.
+ *
+ * A watchdog is maintained for each CPU in the system, that way if
+ * one CPU suffers a lockup, we also get a register dump and reset.
+ * The userspace ping resets the watchdog on all CPUs.
+ *
+ * Before userspace opens the watchdog device, we still run the
+ * watchdogs to catch any lockups that may be kernel related.
