The patch 1 fix the regression by removing incorrect CONFIG_KEXEC
ifdeffery scope adding in arm's <asm/kexec.h>, then dropping the
select of KEXEC for CRASH_DUMP. This is tested and passed a cross
comiping of arm.
Patch 2 is to fix a build failure when I tested patch 1 on x86_64, the
wrong CONFIG_KEXEC iddeffery is replaced with CONFIG_KEXEC_CORE. Test
passed on x86_64.
Patch 3 is to fix an unnecessary 'select KEXEC' in s390 ARCH. Removing
the select won't impact anything. Test passed on a ibm-z system.
