#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Thomas Gleixner:
#      "Two last minute fixes:
#     
#        - Prevent value evaluation via functions happening in the user access
#          enabled region of __put_user() (put another way: make sure to
#          evaluate the value to be stored in user space _before_ enabling
#          user space accesses)
#     
#        - Correct the definition of a Hyper-V hypercall constant"
#     
#     * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/hyper-v: Fix definition of HV_MAX_FLUSH_REP_COUNT
#       x86/uaccess: Don't leak the AC flag into __put_user() value evaluation
