Subject: ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_smp()
X-Git-Url: http://git.efficios.com/?p=deliverable%2Flinux.git;a=commitdiff_plain;h=aa0efcde45a36d1ea2bc5bde4d47f36ec17502de

ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_smp()

MCIP now registers it's own per cpu setup routine (for IPI IRQ request)
using smp_ops.init_irq_cpu().

So no need for platforms to do that. This now completely decouples
platforms from MCIP.
