[PATCH] Kdump: powerpc and s390 build failure fix

Browse Source 
)

From: Vivek Goyal <vgoyal@in.ibm.com>

crash_setup_regs() is an architecture dependent function which is called in
architecture independent section.  So every architecture supporting kexec
should at least provide a dummy definition of crash_setup_regs() even if
crash dumping is not implemented yet, to avoid build failures.
