ARM: SMP: pass an ipi number to smp_cross_call() This allows us to use smp_cross_call() to trigger a number of different software generated interrupts, rather than combining them all on one SGI. Recover the SGI number via do_IPI. Reviewed-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
