x86: merge setup_memory_map with e820

2008-07-08T08:38:25Z

... 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

2008-07-08T08:38:14Z

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

2008-07-08T08:35:38Z

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: make 32-bit use e820_register_active_regions()

2008-06-04T10:01:58Z

this way 32-bit is more similar to 64-bit, and smarter e820 and numa. Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86, 32-bit: change propagate_e820_map() back to find_max_pfn()

2008-06-03T11:26:25Z

we don't need to call memory_present that early. numa and sparse will call memory_present later and might even fail, it will call memory_present for the full range. also for sparse it will call alloc_bootmem ... before we set up bootmem. Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: move e820_mark_nosave_regions to e820.c

2008-05-25T09:35:53Z

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: make e820.c to have common functions

2008-05-25T08:55:10Z

remove the duplicated copy of these functions. Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: fix trimming e820 with MTRR holes. - fix

2008-05-25T08:55:10Z

v2: process hole then end_pfn fix update_memory_range with whole cover comparing Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: fix trimming e820 with MTRR holes.

2008-05-25T08:55:09Z

converting MTRR layout from continous to discrete, some time could run out of MTRRs. So add gran_sizek to prevent that by dumpping small RAM piece less than gran_sizek. previous trimming only can handle highest_pfn from mtrr to end_pfn from e820. when have more than 4g RAM installed, there will be holes below 4g. so need to check ram below 4g is coverred well. need to be applied after [PATCH] x86: mtrr cleanup for converting continuous to discrete layout v7 Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: move i386 memory setup code to e820_32.c

2008-05-25T08:55:09Z

The x86_64 code has centralized the memory setup code in e820_64.c. This patch copies that approach to i386: - early_param("mem", ...) parsing is moved from setup_32.c to e820_32.c. - setup_memory_map() and finish_e820_parsing() are factored out from setup_arch(), and declarations are added to e820_32.h. - print_memory_map() is made static and removed from e820_32.h. - user_defined_memmap is marked as __initdata.
