2008-07-08x86: make 64bit identify_cpu use cpu_dev v2Yinghai Lu
v2: fix early_panic on this config: http://redhat.com/~mingo/misc/config-Thu_Jun_19_14_22_37_CEST_2008.bad reason : struct cpu_vendor_dev size is 16, need to make table to be 16 byte alignment also print out the cpu supported...

2008-04-28x86_64 vDSO: use initdataRoland McGrath
The 64-bit vDSO image is in a special ".vdso" section for no reason I can determine. Furthermore, the location of the vdso_end symbol includes some wrongly-calculated padding space in the image, which is then (correctly) rounded to page size, resulting in an extra page of zeros in the image mapped in to user processes. This changes it to put the vdso.so image into normal initdata as we have always done for the 32-bit vDSO images. The extra padding is gone, so the user VMA is one page instead of two. The image that was already copied around at boot time is now in initdata, so we recover that wasted space after boot.

2008-04-17x86: use ELF section to list CPU vendor specific codeThomas Petazzoni
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.

2008-02-19x86: lds - Use THREAD_SIZE instead of numeric constantCyrill Gorcunov
Though we use PDA for regular task stack but that is not acceptable for init_task wich is special one. We still have to allocate init_task's stack in that manner.

2008-02-19x86: lds - Use PAGE_SIZE instead of numeric constantCyrill Gorcunov
It's much better to use PAGE_SIZE then magic 4096 (though it's almost synonym in most cases on x86 but not for *all* cases ;) Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
