| * x86: consolidate header guardsVegard Nossum2008-07-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>

|/ | | | | | | | | Fix function prototype in header file to match source code: linux-next-20080807/arch/x86/kernel/efi_64.c:100:14: error: symbol 'efi_ioremap' redeclared with different type (originally declared at include2/asm/efi.h:89) - different address spaces Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: reserve EFI memory map with reserve_earlyHuang, Ying2008-06-051-1/+1
| | | | | | | | | | | | | This patch reserves the EFI memory map with reserve_early(). Because EFI memory map is allocated by bootloader, if it is not reserved by reserved_early(), it may be overwritten through address returned by find_e820_area().

* x86: introduce max_pfn_mappedThomas Gleixner2008-01-301-2/+0
| | | | | | | | | | | 64bit uses end_pfn_map and 32bit uses max_low_pfn. There are several files which have #ifdef'ed defines which map either to end_pfn_map or max_low_pfn. Replace this by a universal define and clean up all the other instances. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: fix some bugs about EFI runtime code mappingHuang, Ying2008-01-301-1/+0
| | | | | | | | | | | | | | | | | This patch fixes some bugs of making EFI runtime code executable. - Use change_page_attr in i386 too. Because the runtime code may be mapped not through ioremap. - If there is no _PAGE_NX in __supported_pte_mask, the change_page_attr is not called. - Make efi_ioremap map pages as PAGE_KERNEL_EXEC_NOCACHE, because EFI runtime code may be mapped through efi_ioremap.

| | | | | | | | | | | This patch renames bt_ioremap to early_ioremap, which is used in x86_64. This makes it easier to merge i386 and x86_64 usage.

* x86: EFI runtime service supportHuang, Ying2008-01-301-0/+70
This patch adds basic runtime services support for EFI x86_64 system. The main file of the patch is the addition of efi_64.c for x86_64. This file is modeled after the EFI IA32 avatar. EFI runtime services initialization are implemented in efi_64.c. Some x86_64 specifics are worth noting here. On x86_64, parameters passed to EFI firmware services need to follow the EFI calling convention. For this purpose, a set of functions named efi_call<x> (<x> is the number of parameters) are implemented. EFI function calls are wrapped before calling the firmware service. The duplicated code between efi_32.c and efi_64.c is placed in efi.c to remove them from efi_32.c.
