2008-09-08x86: make 64 bit to use amd.cYinghai Lu
arch/x86/kernel/cpu/amd.c is now 100% identical to arch/x86/kernel/cpu/amd_64.c, so use amd.c on 64-bit too and fix up the namespace impact. Simplify the Kconfig glue as well. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-09-05x86: use cpu/common.c on 64 bitYinghai Lu
Use cpu/common.c on both 64-bit and 32-bit and remove cpu/common_64.c. We started out with this linecount: 816 arch/x86/kernel/cpu/common_64.c 805 arch/x86/kernel/cpu/common.c and the resulting common.c is 1197 lines long, so there's already 424 lines of code eliminated in this phase of the unification.

2008-09-04x86: delay early cpu initialization until cpuid is doneKrzysztof Helt
Move early cpu initialization after cpu early get cap so the early cpu initialization can fix up cpu caps. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-09-04x86: move mtrr cpu cap setting early in early_init_xxxxYinghai Lu
Krzysztof Helt found MTRR is not detected on k6-2 root cause: we moved mtrr_bp_init() early for mtrr trimming, and in early_detect we only read the CPU capability from cpuid, so some cpu doesn't have that bit in cpuid. So we need to add early_init_xxxx to preset those bit before mtrr_bp_init for those earlier cpus. this patch is for v2.6.27 Reported-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
