This struct is only used in xstate.c and asm/elf.h is not a UAPI
header. So what's the point of declaring it in the header instead of
xtsate.c?
If this needs to provided for user space consumption, then it want's to
be in a UAPI header, no?
Our initial idea is to pass the "struct xfeat_component" through "glibc".
is "include/uapi/linux/elf.h" proper header to add this ?
I couldn't see any proper header inside "arch/x86/include/uapi/asm/".
Please advise.
