* [PATCH] mmconfig: Fix x86_64 ioremap base_addressOGAWA Hirofumi2007-02-13
| | | | | | | | | | | | | | | | | | | | | Current mmconfig has some problems of remapped range. a) In the case of broken MCFG tables on Asus etc., we need to remap 256M range, but currently only remap 1M. b) The base address always corresponds to bus number 0, but currently we are assuming it corresponds to start bus number. This patch fixes the above problems. (akpm: Arjan suggests that if the MCFG table is broken we just shouldn't use it, rather than try to work around things).

* [PATCH] mmconfig: Detect and support the E7520 and the 945G/GZ/P/PLOlivier Galibert2007-02-13
| | | | | | | | | | | It seems that the only way to reliably support mmconfig in the presence of funky biosen is to detect the hostbridge and read where the window is mapped from its registers. Do that for the E7520 and the 945G/GZ/P/PL for a start.

* [PATCH] i386: Convert i386 PDA code to use %fsJeremy Fitzhardinge2007-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the PDA code to use %fs rather than %gs as the segment for per-processor data. This is because some processors show a small but measurable performance gain for reloading a NULL segment selector (as %fs generally is in user-space) versus a non-NULL one (as %gs generally is). On modern processors the difference is very small, perhaps undetectable. Some old AMD "K6 3D+" processors are noticably slower when %fs is used rather than %gs; I have no idea why this might be, but I think they're sufficiently rare that it doesn't matter much. This patch also fixes the math emulator, which had not been adjusted to match the changed struct pt_regs.

* [PATCH] x86-64: x86_64-make-the-numa-hash-function-nodemap-allocation fix fixAmul Shah2007-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Removed an extraneous debug message from allocate_cachealigned_map - Changed extract_lsb_from_nodes to return 63 for the case where there was only one memory node. The prevents the creation of the dynamic hashmap. - Changed extract_lsb_from_nodes to use only the starting memory address of a node. On an ES7000, our nodes overlap the starting and ending address, meaning, that we see nodes like 00000 - 10000 10000 - 20000 But other systems have nodes whose start and end addresses do not overlap. For example: 00000 - 0FFFF 10000 - 1FFFF In this case, using the ending address will result in an LSB much lower than what is possible. In this case an LSB of 1 when in reality it should be 16.

* [PATCH] x86-64: Allocate the NUMA hash function nodemap dynamicallyAmul Shah2007-02-13
| | | | | | | | | | | | | | | | 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).

* [PATCH] x86-64: Add __copy_from_user_nocacheAndi Kleen2007-02-13
| | | | | | | | | | | | This does user copies in fs write() into the page cache with write combining. This pushes the destination out of the CPU's cache, but allows higher bandwidth in some case. The theory is that the page cache data is usually not touched by the CPU again and it's better to not pollute the cache with it. Also it is a little faster. Signed-off-by: Andi Kleen <ak@suse.de>
