# Merge: 35c222fd3236 45fc24e89b7c
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'mpx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/daveh/x86-mpx
#     
#     Pull x86 MPX removal from Dave Hansen:
#      "MPX requires recompiling applications, which requires compiler
#       support. Unfortunately, GCC 9.1 is expected to be be released without
#       support for MPX. This means that there was only a relatively small
#       window where folks could have ever used MPX. It failed to gain wide
#       adoption in the industry, and Linux was the only mainstream OS to ever
#       support it widely.
#     
#       Support for the feature may also disappear on future processors.
#     
#       This set completes the process that we started during the 5.4 merge
#       window when the MPX prctl()s were removed. XSAVE support is left in
#       place, which allows MPX-using KVM guests to continue to function"
