Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/*
* structures and definitions for the int 15, ax=e820 memory map

* In a nutshell, arch/i386/boot/setup.S populates a scratch table
* in the empty_zero_block that contains a list of usable address/size
* duples. In arch/i386/kernel/setup.c, this information is
* transferred into the e820map, and in arch/i386/mm/init.c, that
* new information is used to mark pages reserved or not.

[PATCH] x86_64: Introduce e820_all_mapped Introduce a e820_all_mapped() function which checks if the entire range <start,end> is mapped with type. This is done by moving the local start variable to the end of each known-good region; if at the end of the function the start address is still before end, there must be a part that's not of the correct type; otherwise it's a good region.

[PATCH] x86: fix amd64-agp aperture validation Under CONFIG_DISCONTIGMEM, assuming that a !pfn_valid() implies all subsequent pfn-s are also invalid is wrong. Thus replace this by explicitly checking against the E820 map.

[PATCH] compile error of register_memory() register_memory() becomes double definition in 2.6.20-rc1. It is defined in arch/i386/kernel/setup.c as static definition in 2.6.19. But it is moved to arch/i386/kernel/e820.c in 2.6.20-rc1. And same name function is defined in driver/base/memory.c too. So, it becomes cause of compile error of duplicate definition if memory hotplug option is on.

i386: do not restore reserved memory after hibernation On some systems the ACPI NVS area is located in the first 1 MB of RAM and it is overwritten by the i386 code during the restore after hibernation. This confuses the ACPI platform firmware that doesn't update the AC adapter status appropriately as a result (http://bugzilla.kernel.org/show_bug.cgi?id=7995). The solution is to register the reserved memory in the first 1 MB as 'nosave', so that swsusp doesn't touch it during the restore. Also, this has been done on x86_64 for a long time now, so this patch makes the i386 restore code behave like the x86_64 one. [akpm@linux-foundation.org: build fix] Signed-off-by: Rafael J.
