x86: merge setup_memory_map with e820

2008-07-08T08:38:25+00:00

... and kill e820_32/64.c and e820_32/64.h Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: move e820_resource_resources to e820.c

2008-07-08T08:38:14+00:00

and make 32-bit resource registration more like 64 bit. also move probe_roms back to setup_32.c Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: e820 merge parsing of the mem=/memmap= boot parameters

2008-07-08T08:35:38+00:00

since we now have 32-bit support for e820_register_active_regions(), we can merge the parsing of the mem=/memmap= boot parameters. Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: move e820_register_active() to e820.c

2008-06-04T10:01:57+00:00

to prepare 32-bit to use it. Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: clean up max_pfn_mapped usage - 64-bit

2008-06-03T11:26:29+00:00

on 64-bit we only get valid max_pfn_mapped after init_memory_mapping(). Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: move e820_mark_nosave_regions to e820.c

2008-05-25T09:35:53+00:00

and make e820_mark_nosave_regions to take limit_pfn to use max_low_pfn for 32bit and end_pfn for 64bit Signed-off-by: Yinghai Lu Cc: Andrew Morton Signed-off-by: Thomas Gleixner

x86: include pci.h in e820_64.c

2008-05-25T08:55:12+00:00

global pci_mem_start needs a declaration. include pci.h Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

x86: extend e820 ealy_res support 32bit

2008-05-25T08:55:11+00:00

move early_res related from e820_64.c to e820.c make edba detection to be done in head32.c remove smp_alloc_memory, because we have fixed trampoline address now.

x86 boot: change sanitize_e820_map parameter from byte to int to allow bigger memory maps

2008-05-25T08:55:11+00:00

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. Signed-off-by: Paul Jackson Signed-off-by: Ingo Molnar
