* [PATCH] x86: fix amd64-agp aperture validationJan Beulich2007-05-021-0/+1
| | | | | | | | | | | | 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()Yasunori Goto2006-12-221-1/+1
| | | | | | | | | | | | | 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.

* [PATCH] x86_64: Introduce e820_all_mappedArjan van de Ven2006-04-091-0/+4
| | | | | | | | | | | | | | 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] Increase number of e820 entries hard limit from 32 to 128Venkatesh Pallipadi2005-05-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The specifications that talk about E820 map doesn't have an upper limit on the number of e820 entries. But, today's kernel has a hard limit of 32. With increase in memory size, we are seeing the number of E820 entries reaching close to 32. Patch below bumps the number upto 128. The patch changes the location of EDDBUF in zero-page (as it comes after E820). As, EDDBUF is not used by boot loaders, this patch should not have any effect on bootloader-setup code interface. Patch covers both i386 and x86-64. Tested on: * grub booting bzImage * lilo booting bzImage with EDID info enabled * pxeboot of bzImage Side-effect: bss increases by ~ 2K and init.data increases by ~7.5K on all systems, due to increase in size of static arrays.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+40
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!
