From 0df7095205cbf6ea1cdfe6254e0d6a3b823caa3b Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 2 Dec 2010 19:16:56 +0000 Subject: [PATCH] ARM: SMP: remove IRQ-disabling for smp_cross_call() As we've now removed the spinlock and bitmask, we have nothing left which requires interrupts to be disabled when sending an IPI. All current IPI-sending implementations use the GIC, which also does not require interrupts disabled when calling gic_raise_softirq(). Remove the now unnecessary IRQ disable.
