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.

[PATCH] kdump: dynamic per cpu allocation of memory for saving cpu registers 2006-01-10T16:01:26+00:00 Vivek Goyal vgoyal@in.ibm.com 2006-01-10T04:51:41+00:00 cc57165874e938ef684d71ba7d36e7088b551489 - In case of system crash, current state of cpu registers is saved in memory in elf note format. So far memory for storing elf notes was being allocated statically for NR_CPUS. - This patch introduces dynamic allocation of memory for storing elf notes. It uses alloc_percpu() interface. This should lead to better memory usage. - Introduced based on Andi Kleen's and Eric W. Biederman's suggestions. - This patch also moves memory allocation for elf notes from architecture dependent portion to architecture independent portion. Now crash_notes is architecture independent. The whole idea is that size of memory to be allocated per cpu (MAX_NOTE_BYTES) can be architecture dependent and allocation of this memory can be architecture independent.
