SubjectRe: [RFC 1/9] mm, arm64: Update PR_SET/GET_TAGGED_ADDR_CTRL interface
From

Hi Catalin,

I noticed there are some ELF bits for ARM's BTI feature:

GNU_PROPERTY_AARCH64_FEATURE_1_BTI

> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/elf.h#n453

There's been talk of needing a similar set of bits on x86 for tagged
pointers (LAM). Do you have any plans to do something similar (ELF
property bits) for any of the pointer tagging features?
