The use of __weak is being eliminated within kexec sources.
The technique uses macros mapped onto inline functions in

This patchset was using __weak and so in order to replace
__weak, this patch introduces arch/*/asm/crash.h, patterned
after how kexec is moving away from __weak and to the macro
definitions.
Are you going to replace __weak in kexec of arll ARCHes? I don't see
your point why all these empty header files are introduced. Wondering
what's impacted if not adding these empty files?
Hi Baoquan,
In this patchset, to file include/linux/crash_core.h I added the line #include <asm/crash.h>.
I patterned this after how include/linux/kexec.h does #include <asm/kexec.h>.
I am sorry, Eric, it looks not so good. I understand you want to pattern
asm/kexe.h, but we need consider reality. Introducing a dozen of empty
header file and not being able to tell when they will be filled doesn't
make sense.
Includig <asm/crash.h> where needed is much simpler. I doubt if your way
can pass other reviewers' line. Can you reconsider?
