2008-04-27x86_64: fix setup_node_bootmem to support big mem excluding with memmapYinghai Lu3-12/+46
typical case: four sockets system, every node has 4g ram, and we are using: memmap=10g$4g to mask out memory on node1 and node2 when numa is enabled, early_node_mem is used to get node_data and node_bootmap. if it can not get memory from the same node with find_e820_area(), it will use alloc_bootmem to get buff from previous nodes. so check it and print out some info about it. need to move early_res_to_bootmem into every setup_node_bootmem. and it takes range that node has. otherwise alloc_bootmem could return addr that reserved early. depends on "mm: make reserve_bootmem can crossed the nodes".

2008-04-27x86_64: make reserve_bootmem_generic() use new reserve_bootmem()Yinghai Lu1-2/+8
"mm: make reserve_bootmem can crossed the nodes" provides new reserve_bootmem(), let reserve_bootmem_generic() use that. reserve_bootmem_generic() is used to reserve initramdisk, so this way we can make sure even when bootloader or kexec load ranges cross the node memory boundaries, reserve_bootmem still works.

2008-04-26x86, bitops: select the generic bitmap search functionsAlexander van Heukelum4-22/+5
Introduce GENERIC_FIND_FIRST_BIT and GENERIC_FIND_NEXT_BIT in lib/Kconfig, defaulting to off. An arch that wants to use the generic implementation now only has to use a select statement to include them. I added an always-y option (X86_CPU) to arch/x86/Kconfig.cpu and used that to select the generic search functions. This way ARCH=um SUBARCH=i386 automatically picks up the change too, and arch/um/Kconfig.i386 can therefore be simplified a bit. ARCH=um SUBARCH=x86_64 does things differently, but still compiles fine. It seems that a "def_bool y" always wins over a "def_bool n"?

2008-04-26x86: generic versions of find_first_(zero_)bit, convert i386Alexander van Heukelum1-0/+3
Generic versions of __find_first_bit and __find_first_zero_bit are introduced as simplified versions of __find_next_bit and __find_next_zero_bit. Their compilation and use are guarded by a new config variable GENERIC_FIND_FIRST_BIT. The generic versions of find_first_bit and find_first_zero_bit are implemented in terms of the newly introduced __find_first_bit and __find_first_zero_bit. This patch does not remove the i386-specific implementation, but it does switch i386 to use the generic functions by setting GENERIC_FIND_FIRST_BIT=y for X86_32.

2008-04-26x86: merge the simple bitops and move them to bitops.hAlexander van Heukelum1-1/+1
Some of those can be written in such a way that the same inline assembly can be used to generate both 32 bit and 64 bit code. For ffs and fls, x86_64 unconditionally used the cmov instruction and i386 unconditionally used a conditional branch over a mov instruction. In the current patch I chose to select the version based on the availability of the cmov instruction instead. A small detail here is that x86_64 did not previously set CONFIG_X86_CMOV=y. Improved comments for ffs, ffz, fls and variations. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-26x86: change x86 to use generic find_next_bitAlexander van Heukelum4-139/+4
The versions with inline assembly are in fact slower on the machines I tested them on (in userspace) (Athlon XP 2800+, p4-like Xeon 2.8GHz, AMD Opteron 270). The i386-version needed a fix similar to 06024f21 to avoid crashing the benchmark. Benchmark using: gcc -fomit-frame-pointer -Os. For each bitmap size 1...512, for each possible bitmap with one bit set, for each possible offset: find the position of the first bit starting at offset. If you follow ;). Times include setup of the bitmap and checking of the results. Athlon Xeon Opteron 32/64bit x86-specific: 0m3.692s 0m2.820s 0m3.196s / 0m2.480s generic: 0m2.622s 0m1.662s 0m2.100s / 0m1.572s If the bitmap size is not a multiple of BITS_PER_LONG, and no set (cleared) bit is found, find_next_bit (find_next_zero_bit) returns a value outside of the range [0, size]. The generic version always returns exactly size. The generic version also uses unsigned long everywhere, while the x86 versions use a mishmash of int, unsigned (int), long and unsigned long. Using the generic version does give a slightly bigger kernel, though. defconfig: text data bss dec hex filename x86-specific: 4738555 481232 626688 5846475 5935cb vmlinux (32 bit) generic: 4738621 481232 626688 5846541 59360d vmlinux (32 bit) x86-specific: 5392395 846568 724424 6963387 6a40bb vmlinux (64 bit) generic: 5392458 846568 724424 6963450 6a40fa vmlinux (64 bit) Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-26x86: remove NexGen supportDmitri Vorobiev4-65/+5
It is claimed that NexGen CPUs were never shipped: http://lkml.org/lkml/2008/4/20/179 Also, the kernel support for these chips has been broken for a long time, the code intended to support NexGen thereby being essentially dead. As an outcome of the discussion that can be found using the URL above, this patch removes the NexGen support altogether. The changes in this patch survived a defconfig build for i386, a couple of successful randconfig builds, as well as a runtime test, which consisted in booting a 32-bit x86 box up to the shell prompt.

2008-04-26x86: array can become staticDmitri Vorobiev1-1/+1
In arch/x86/kernel/setup_64.c, the standard_io_resources array is needlessly defined as global. This patch makes this variable static. This patch was successfully build-tested using the defconfig for x86_64. Runtime test was performed by booting a 64-bit x86 box up to the shell prompt.

2008-04-26x86: remove unused function amd_init_cpu()Dmitri Vorobiev1-6/+0
There are no users for the function amd_init_cpu() defined in arch/x86/kernel/cpu/amd.c. This patch removes this routine. This patch was build-tested using defconfigs for i386 and x86_64, and a few randconfig instances. Runtime tests were performed by booting 32- and 64-bit x86 boxen up to the shell prompt.

2008-04-26x86-64: extend MCE CPU quirk handlingJan Beulich1-8/+10
At least on my Barcelona, I see MCE log entries after cold boot caused by BIOS not properly clearing the respective registers. Therefore, this patch extends the workaround to families 0x10 and 0x11 (the latter just for completeness, I have nothing to verify this against). At the same time, provide a way to make these entries visible via the 'mce=bootlog' command line option even on these machines.

.. since it uses ILL_BADSTK (which is meaningless in the context of SIGSEGV). Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: fix watchdog ops for CoreDuoJan Beulich1-12/+2
There apparently was an unnoticed conflict between an earlier patch to this file and mine (d1e084746b0e5806e6345ab31c5b370f8dee2b23), which I noticed only now. I suppose a change like the one below (untested) is needed; I didn't get any response on a confirmation request for this from the submitter of the first patch. The issue is the writing of the 'checkbit' member at the end of setup_intel_arch_watchdog(), which my patch made go to intel_arch_wd_ops rather than wd_ops.
