From 2a07870511829977d02609dac6450017b0419ea9 Mon Sep 17 00:00:00 2001 From: Qais Yousef Date: Tue, 8 Dec 2015 13:20:25 +0000 Subject: [PATCH] irqchip/mips-gic: Use gic_vpes instead of NR_CPUS NR_CPUS is set by Kconfig and could be much higher than what actually is in the system. gic_vpes should be a true representitives of the number of cpus in the system, so use it instead.
