| Message-ID | <ur4Uh-7j9-13@gated-at.bofh.it> |
There's typo in recent change of VM_MPX definition. We want it to be
VM_HIGH_ARCH_4, not VM_HIGH_ARCH_BIT_4.

Fixes: df3735c5b40f ("x86,mpx: make mpx depend on x86-64 to free up VMA flag")

Ugh, indeed! Good catch!

Could we get this patch into the next 4.14 rc too? This "typo" causes a bunch of sections in /proc/N/maps to be incorrectly labelled [mpx] which confuses rr. We could probably work around if it we had to but doing this right is trivial. Thanks, - Kyle
