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!

x86: remove extern declarations for code, data, bss resources This patch removes the extern struct resource declarations for data_resource, code_resource and bss_resource on x86 and declares that three structures as static as done on other architectures like IA64. On i386, these structures are moved to setup_32.c (from e820_32.c) because that's code that is not specific to e820 and also required on EFI systems. That makes the "extern" reference superfluous. On x86_64, data_resource, code_resource and bss_resource are passed to e820_reserve_resources() as arguments just as done on i386 and IA64. That also avoids the "extern" reference and it's possible to make it static.

[PATCH] Make swsusp avoid memory holes and reserved memory regions on x86_64 On x86_64 machines with more than 2 GB of RAM there are large memory gaps (with no corresponding kernel virtual addresses) and reserved memory regions between areas of usable physical RAM. Moreover, if CONFIG_FLATMEM is set, they appear within the normal zone. swsusp should not try to save them, so the corresponding page structs have to be marked as 'nosave'. Signed-off-by: Rafael J.

[PATCH] x86_64: Rename e820_mapped to e820_any_mapped Rename e820_mapped to e820_any_mapped since it tests if any part of the range is mapped according to the type. Later steps will introduce e820_all_mapped which will check if the entire range is mapped with the type. Both have their merit.

[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] x86-64: Fix fake numa for x86_64 machines with big IO hole This patch resolves the issue of running with numa=fake=X on kernel command line on x86_64 machines that have big IO hole. While calculating the size of each node now we look at the total hole size in that range. Previously there were nodes that only had IO holes in them causing kernel boot problems. We now use the NODE_MIN_SIZE (64MB) as the minimum size of memory that any node must have. We reduce the number of allocated nodes if the number of nodes specified on kernel command line results in any node getting memory smaller than NODE_MIN_SIZE. This change allows the extra memory to be incremented in NODE_MIN_SIZE granule and uniformly distribute among as many nodes (called big nodes) as possible.

[PATCH] Convert x86-64 to early param Instead of hackish manual parsing Requires earlier i386 patchkit, but also fixes i386 early_printk again. I removed some obsolete really early parameters which didn't do anything useful. Also made a few parameters that needed it early (mostly oops printing setup) Also removed one panic check that wasn't visible without early console anyways (the early console is now initialized after that panic) This cleans up a lot of code.

[PATCH] x86_64: Avoid EBDA area in early boot allocator Based on analysis&patch from Robert Hentosch Observed on a Dell PE6850 with 16GB The problem occurs very early on, when the kernel allocates space for the temporary memory map called bootmap. The bootmap overlaps the EBDA region. EBDA region is not historically reserved in the e820 mapping. When the bootmap is freed it marks the EBDA region as usable. If you notice in setup.c there is already code to work around the EBDA in reserve_ebda_region(), this check however occurs after the bootmap is allocated and doesn't prevent the bootmap from using this range. AK: I redid the original patch. Thanks also to Jan Beulich for spotting some mistakes.

[PATCH] x86-64: Allocate the NUMA hash function nodemap dynamically Remove the statically allocated memory to NUMA node hash map in favor of a dynamically allocated memory to node hash map (it is cache aligned). This patch has the nice side effect in that it allows the hash map to grow for systems with large amounts of memory (256GB - 1TB), but suffer from having small PCI space tacked onto the boot node (which is somewhere between 192MB to 512MB on the ES7000).
