| |
This patch fixes the problem introduced by: http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.23-rc8/2.6.23-rc8-mm2/broken-out/x86-convert-cpuinfo_x86-array-to-a-per_cpu-array.patch
The problem is that every processor line in /proc/cpuinfo displays zero on x86_64.
$ grep processor /proc/cpuinfo processor : 0 processor : 0
Because early_identify_cpu() overwrites c->cpu_index for every cpuinfo. This patch removes that unnecessary initialization for c->cpu_index.
