From d2b965b24895bbeb9c3da59da64eaa67d2d54cc3 Mon Sep 17 00:00:00 2001 From: Matt Redfearn Date: Wed, 10 Aug 2016 17:11:03 +0100 Subject: [PATCH] MIPS: Delete unused file smp-gic.c Commit 7eb8c99db26c ("MIPS: Delete smp-gic.c") removed the file from the Makefile and the option to build it from KConfig, but left the file itself floating in the tree. Remove the unused source file.
