From 19971c0bcb45f264c83cb2fd2bce50457bd17cc4 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 27 Jan 2015 21:45:47 +0000 Subject: MIPS: cevt-r4k: Move handle_perf_irq() out of header Long ago, commit 8531a35e5e27 ("[MIPS] SMTC: Fix SMTC dyntick support.") moved handle_perf_irq() out of cevt-r4k.c into a header so it could be shared with cevt-smtc.c. Slightly less long ago, commit b633648c5ad3 ("MIPS: MT: Remove SMTC support") removed all traces of SMTC support, including cevt-smtc.c, leaving cevt-r4k.c once again the sole user of handle_perf_irq(), therefore move it back into cevt-r4k.c from the header.
