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.
