* x86: add ->pre_time_init to x86_quirksYinghai Lu2008-07-201-0/+10
| | | | | | | | | | | so NUMAQ can use that to call numaq_pre_time_init() This allows us to remove a NUMAQ special from arch/x86/kernel/setup.c. (and paves the way to remove the NUMAQ subarch) Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: introduce x86_quirksYinghai Lu2008-07-201-16/+8

* x86, VisWS: turn into generic arch, add early quirks to default architecturesIngo Molnar2008-07-101-0/+30
| | | | | | | | | add early quirk support to the generic architecture code. this allows VISWS to be supported by the generic code and allows us to remove the VISWS subarch. Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: rename two e820 related functionsYinghai Lu2008-07-081-2/+2
| | | | | | | | | | rename update_memory_range to e820_update_range rename add_memory_region to e820_add_region to make it more clear that they are about e820 map operations. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86 boot: change sanitize_e820_map parameter from byte to int to allow ↵Paul Jackson2008-05-251-1/+4
| | | | | | | | | | | | | | | | | bigger memory maps The map size counter passed into, and back out of, sanitize_e820_map(), was an eight bit type (char or u8), as derived from its origins in legacy BIOS E820 structures. This patch changes that type to an 'int', to allow this sanitize routine to also be used on larger maps (larger than the 256 count that fits in a char). The legacy BIOS E820 interface of course does not change; that remains at 8 bits for this count, holding up to E820MAX == 128 entries. But the kernel internals can handle more when those additional memory map entries are passed from the BIOS via EFI interfaces.

* x86 boot: proper use of ARRAY_SIZE instead of repeated E820MAX constantPaul Jackson2008-05-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is motivated by a subsequent patch which will allow for more memory map entries on EFI supported systems than can be passed via the x86 legacy BIOS E820 interface. The legacy interface is limited to E820MAX == 128 memory entries, and that "E820MAX" manifest constant was used as the size for several arrays and loops over those arrays. The primary change in this patch is to change code loop sizes over those arrays from using the constant E820MAX, to using the ARRAY_SIZE() macro evaluated for the array being looped. That way, a subsequent patch can change the size of some of these arrays, without breaking this code. This patch also adds a parameter to the sanitize_e820_map() routine, which had an implicit size for the array passed it of E820MAX entries. This new parameter explicitly passes the size of said array. Once again, this will allow a subsequent patch to change that array size for some calls to sanitize_e820_map() without breaking the code. As part of enhancing the sanitize_e820_map() interface this way, I further combined the unnecessarily distinct x86_32 and x86_64 declarations for this routine into a single, commonly used, declaration. This patch in itself should make no difference to the resulting kernel binary. [ mingo@elte.hu: merged to -tip ] Signed-off-by: Paul Jackson <pj@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
