From 861667dc82f561e65336ea67f73021b782b4ff74 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 8 Aug 2012 16:59:43 +0200 Subject: MIPS: Fix race condition in module relocation code. The relocation code was essentially taken from the 2.4 modutils which perform relocation in userspace. In 2.6 relocation of multiple modules may be performed in parallel by the in-kernel loader so the global variable mips_hi16_list won't fly anymore. Fix race by moving it into mod_arch_specific. [ralf@linux-mips.org: folded in Tony's followup fix.
