From 7eca5b1460f3f1ad3891252743c36f309df53d53 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 27 Jan 2015 21:45:49 +0000 Subject: [PATCH] MIPS: Remove redundant IPTI==IPPCI logic The situation where the timer interrupt is on the same line as the performance counter interrupt is handled in per_cpu_trap_init() by setting cp0_perfcount_irq to -1, so there is no need to duplicate the logic conditional upon cp0_perfcount_irq >= 0 in perf (init_hw_perf_events()) and oprofile (mipsxx_init()).
