* [PATCH] i386: Fix a typo in an IRQ handler nameMaciej W. Rozycki2007-02-13

* [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>

* [SPARC]: Re-export saved_command_line to modules.David S. Miller2007-02-12
| | | | | | | | | | | | | This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by: David S. Miller <davem@davemloft.net>

Note that the original AT91 GPIO calls merged the "mux pin as GPIO" and "set GPIO direction" functionality into one API call, contrary to what's specified as a cross-platform portable model. So this involved a few non-inlinable functions.

* | [PATCH] tty: update the tty layer to work with struct pidEric W. Biederman2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Of kernel subsystems that work with pids the tty layer is probably the largest consumer. But it has the nice virtue that the assiation with a session only lasts until the session leader exits. Which means that no reference counting is required. So using struct pid winds up being a simple optimization to avoid hash table lookups. In the long term the use of pid_nr also ensures that when we have multiple pid spaces mixed everything will work correctly. Signed-off-by: Eric W.

The sunos compatibility code is one of the last users of the old pid_t based kill_pg in the kernel. By being complete I allow for the future removal of kill_pg from the kernel, which will ensure I don't miss something. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This macro was used to save static registers before calling sys_sigsuspend() and sys_sigreturn(). For the sys_sigreturn() case, there's no point to save them since they have been already saved by setup_sigcontext() before calling the signal handler. For the sys_sigsuspend() case, I don't see any reasons... Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
