x86: EFI: Back efi_ioremap with init_memory_mapping instead of FIX_MAP

2009-03-04T18:20:16Z

Impact: Fix boot failure on EFI system with large runtime memory range Brian Maly reported that some EFI system with large runtime memory range can not boot. Because the FIX_MAP used to map runtime memory range is smaller than run time memory range. This patch fixes this issue by re-implement efi_ioremap() with init_memory_mapping().

x86: trivial printk fix in efi.c

2008-10-03T08:18:30Z

[patch] x86: Trivial printk fix in efi.c The following line is lacking a space between "memdesc" and "doesn't". "Kernel-defined memdescdoesn't match the one from EFI!" Fixed the printk by adding a space. Signed-off-by: Russ Anderson Cc: Russ Anderson Signed-off-by: Ingo Molnar

x86: introduce max_low_pfn_mapped for 64-bit

x86 boot: only pick up additional EFI memmap if add_efi_memmap flag

2008-07-08T11:10:41Z

Applies on top of the previous patch: x86 boot: add code to add BIOS provided EFI memory entries to kernel Instead of always adding EFI memory map entries (if present) to the memory map after initially finding either E820 BIOS memory map entries and/or kernel command line memmap entries, -instead- only add such additional EFI memory map entries if the kernel boot option: add_efi_memmap is specified. Requiring this 'add_efi_memmap' option is backward compatible with kernels that didn't load such additional EFI memory map entries in the first place, and it doesn't override a configuration that tries to replace all E820 or EFI BIOS memory map entries with ones given entirely on the kernel command line.

x86 boot: x86_64 efi compiler warning fix

2008-07-08T10:50:29Z

Fix a compiler warning. Rather than always casting a u32 to a pointer (which generates a warning on x86_64 systems) instead separate the x86_32 and x86_64 assignments entirely with ifdefs. Until other recent changes to this code, it used to have x86_64 separated like this.

x86: rename two e820 related functions

2008-07-08T08:37:01Z

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 Signed-off-by: Ingo Molnar

x86: reserve EFI memory map with reserve_early

2008-06-05T13:10:02Z

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().
