# Merge: 1395d109cddc ff924c5a1ec7
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun Sep 2 10:11:30 2018 -0700
# 
#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Thomas Gleixner:
#      "Speculation:
#     
#        - Make the microcode check more robust
#     
#        - Make the L1TF memory limit depend on the internal cache physical
#          address space and not on the CPUID advertised physical address
#          space, which might be significantly smaller. This avoids disabling
#          L1TF on machines which utilize the full physical address space.
#     
#        - Fix the GDT mapping for EFI calls on 32bit PTI
#     
#        - Fix the MCE nospec implementation to prevent #GP
#     
#       Fixes and robustness:
#     
#        - Use the proper operand order for LSL in the VDSO
#     
#        - Prevent NMI uaccess race against CR3 switching
#     
#        - Add a lockdep check to verify that text_mutex is held in
#          text_poke() functions
#     
#        - Repair the fallout of giving native_restore_fl() a prototype
#     
#        - Prevent kernel memory dumps based on usermode RIP
#     
#        - Wipe KASAN shadow stack before rewinding the stack to prevent false
#          positives
#     
#        - Move the AMS GOTO enforcement to the actual build stage to allow
#          user API header extraction without a compiler
#     
#        - Fix a section mismatch introduced by the on demand VDSO mapping
#          change
#     
#       Miscellaneous:
#     
#        - Trivial typo, GCC quirk removal and CC_SET/OUT() cleanups"
