MIPS: kexec: remove SMP_DUMP
SMP_DUMP has been added as a new IPI signal when kexec support was added for Cavium Octeon CPUs ('commit 7aa1c8f47e7e ("MIPS: kdump: Add support")'. However, the new signal doesn't appear to ever have a proper handler added (octeon_message_functions[] array has an empty handler for it), and generic IPI handlers now trigger a BUG() on unhandled signal. As the method is unused remove it completely and replace its only invocation with a smp_call_function(). [ralf@linux-mips.org: Renumber SMP_ASK_C0COUNT to avoid numbering gaps.] Signed-off-by: Marcin Nowakowski <marcin.nowakowski@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/14630/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
