SubjectRe: [PATCH v2 -tip] x86/percpu: Use C for arch_raw_cpu_ptr()

We could emit a non-aligned end-of-text symbol (we might have it already),
and have a script or small .c program in scripts/ or tools/ that looks
at vmlinux and displays a user-friendly and accurate list of text and
data sizes in the kernel?

And since objtool is technically an 'object files tool', and it already
looks at sections & symbols, it could also grow a:

objtool size <objfile>

command that does the sane thing ... I'd definitely start using that, instead of 'size'.

/me runs :-)

Thanks,

Ingo
