We want to make function reserve_crashkernel[_low](), which is implemented

Please use passive voice in your commit message: no "we" or "I", etc,
and describe your changes in imperative mood.

Also, pls read section "2) Describe your changes" in
Documentation/process/submitting-patches.rst for more details.

Bottom line is: personal pronouns are ambiguous in text, especially with
so many parties/companies/etc developing the kernel so let's avoid them
please.

by X86, available to other architectures. It references macro CRASH_ALIGN

"x86"

and will be moved to public crash_core.c. But the defined values of
CRASH_ALIGN may be different in different architectures. So moving the
definition of CRASH_ALIGN to asm/kexec.h is a good choice.

The reason for moving CRASH_ADDR_{LOW|HIGH}_MAX is the same as above.

This commit message needs to say something along the lines of:

"Move CRASH_ALIGN and ... to the arch-specific header in preparation
of making reserve_crashkernel[_low]() generic, used by other
architectures."

or so.
