Huang Ying	9868ee63b8	kexec/i386: setup kexec page table in C ... Impact: change the kexec bootstrap code implementation from assembly to C This patch transforms the kexec page tables setup code from assembler code to C code in machine_kexec_prepare. This improves readability and reduces code line number. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>	2008-10-31 10:01:57 +01:00
Huang Ying	92be3d6bdf	kexec/i386: allocate page table pages dynamically ... Impact: save .text size when kexec is built in but not loaded This patch adds an architecture specific struct kimage_arch into struct kimage. The pointers to page table pages used by kexec are added to struct kimage_arch. The page tables pages are dynamically allocated in machine_kexec_prepare instead of statically from BSS segment. This will save up to 20k memory when kexec image is not loaded. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>	2008-10-31 10:01:56 +01:00
H. Peter Anvin	1965aae3c9	x86: Fix ASM_X86__ header guards ... Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H.
