Merge tag 'core_core_updates_for_5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull READ_IMPLIES_EXEC changes from Borislav Petkov:
"Split the old READ_IMPLIES_EXEC workaround from executable
PT_GNU_STACK now that toolchains long support PT_GNU_STACK marking and
there's no need anymore to force modern programs into having all its
user mappings executable instead of only the stack and the PROT_EXEC
ones.
Disable that automatic READ_IMPLIES_EXEC forcing on x86-64 and
arm64.
Add tables documenting how READ_IMPLIES_EXEC is handled on x86-64, arm
and arm64.
By Kees Cook"
