* x86, cpu: mv display_cacheinfo -> cpu_detect_cache_sizesBorislav Petkov2009-11-23
| | | | | | | | | display_cacheinfo() doesn't display anything anymore and it is used to detect CPU cache sizes. Rename it accordingly. Signed-off-by: Borislav Petkov <petkovbb@gmail.com> LKML-Reference: <20091121130145.GA31357@liondog.tnic> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* x86: move various CPU initialization objects into .cpuinit.rodataJan Beulich2009-03-12
| | | | | | | | | | | | Impact: debuggability and micro-optimization Putting whatever is possible into the (final) .rodata section increases the likelihood of catching memory corruption bugs early, and reduces false cache line sharing.

* x86: remove cpu_vendor_devYinghai Lu2008-09-04
| | | | | | | | | | | | 1. add c_x86_vendor into cpu_dev 2. change cpu_devs to static 3. check c_x86_vendor before put that cpu_dev into array 4. remove alignment for 64bit 5. order the sequence in cpu_devs according to link sequence... so could put intel at first, then amd...

* x86: use ELF section to list CPU vendor specific codeThomas Petazzoni2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | Replace the hardcoded list of initialization functions for each CPU vendor by a list in an ELF section, which is read at initialization in arch/x86/kernel/cpu/cpu.c to fill the cpu_devs[] array. The ELF section, named .x86cpuvendor.init, is reclaimed after boot, and contains entries of type "struct cpu_vendor_dev" which associates a vendor number with a pointer to a "struct cpu_dev" structure. This first modification allows to remove all the VENDOR_init_cpu() functions. This patch also removes the hardcoded calls to early_init_amd() and early_init_intel(). Instead, we add a "c_early_init" member to the cpu_dev structure, which is then called if not NULL by the generic CPU initialization code. Unfortunately, in early_cpu_detect(), this_cpu is not yet set, so we have to use the cpu_devs[] array directly. This patch is part of the Linux Tiny project, and is needed for further patch that will allow to disable compilation of unused CPU support code.

* x86: add cpu init function defintions to cpu.hHarvey Harrison2008-02-04
| | | | | | | | | | | | | | | | | | | cpu.h was already included everywhere needed. Fixes following sparse warnings: arch/x86/kernel/cpu/amd.c:343:12: warning: symbol 'amd_init_cpu' was not declared.

* x86: move X86_FEATURE_CONSTANT_TSC into early cpu feature detectionAndi Kleen2008-01-30
| | | | | | | | | | | | Need this in the next patch in time_init and that happens early. This includes a minor fix on i386 where early_intel_workarounds() [which is now called early_init_intel] really executes early as the comments say.
