Linus Torvalds ac7b34218a 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.
