Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"A set of small fixes:
- make KGDB work again which got broken by the conversion of WARN()
to #UD. The WARN fixup needs to run before the notifier callchain,
otherwise KGDB tries to handle it and crashes.
- disable KASAN in the ORC unwinder to prevent false positive KASAN
warnings
- prevent default mapping above 47bit when 5 level page tables are
enabled
- make the delay calibration optimization work correctly, which had
the conditionals the wrong way around and was operating on data
which was not yet updated.
- remove the bogus X86_TRAP_BP trap init from the default IDT init
table, which broke 32bit int3 handling by overwriting the correct
int3 setup.
- replace this_cpu* with boot_cpu_data access in the preemptible
oprofile init code"
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/debug: Handle warnings before the notifier chain, to fix KGDB crash
x86/mm: Fix ELF_ET_DYN_BASE for 5-level paging
x86/idt: Remove X86_TRAP_BP initialization in idt_setup_traps()
x86/oprofile/ppro: Do not use __this_cpu*() in preemptible context
x86/unwind: Disable KASAN checking in the ORC unwinder
x86/smpboot: Make optimization of delay calibration work correctly
