# Merge: 351e1aa6cb4b 625210cfa6c0
# Author: Linus Torvalds <torvalds@linux-foundation.org>

# 
#     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 fixes for x86:
#     
#        - Fix the swapped outb() parameters in the KASLR code
#     
#        - Fix the PKEY handling at fork which missed to preserve the pkey
#          state for the child. Comes with a test case to validate that.
#     
#        - Fix the entry stack handling for XEN PV to respect that XEN PV
#          systems enter the function already on the current thread stack and
#          not on the trampoline.
#     
#        - Fix kexec load failure caused by using a stale value when the
#          kexec_buf structure is reused for subsequent allocations.
#     
#        - Fix a bogus sizeof() in the memory encryption code
#     
#        - Enforce PCI dependency for the Intel Low Power Subsystem
#     
#        - Enforce PCI_LOCKLESS_CONFIG when PCI is enabled"
#     
#     * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/Kconfig: Select PCI_LOCKLESS_CONFIG if PCI is enabled
#       x86/entry/64/compat: Fix stack switching for XEN PV
#       x86/kexec: Fix a kexec_file_load() failure
#       x86/mm/mem_encrypt: Fix erroneous sizeof()
#       x86/selftests/pkeys: Fork() to check for state being preserved
#       x86/pkeys: Properly copy pkey state at fork()
#       x86/kaslr: Fix incorrect i8254 outb() parameters
#       x86/intel/lpss: Make PCI dependency explicit
