2008-04-26x86: cleanup clocksource_hz2mult usageAkinobu Mita
Remove the magic number in the second argument of clocksource_hz2mult() Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: remove unnecessary memset and NULL check after alloc_bootmem()Akinobu Mita
memset and NULL check after alloc_bootmem() are unnecessary. Because it returns zeroed memory and it never return NULL. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-26x86_64 ia32 ptrace: convert to compat_arch_ptraceRoland McGrath
Now that there are no more special cases in sys32_ptrace, we can convert to using the generic compat_sys_ptrace entry point. The sys32_ptrace function gets simpler and becomes compat_arch_ptrace. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86_64 ia32 ptrace: use compat_ptrace_request for siginfoRoland McGrath
This removes the special-case handling for PTRACE_GETSIGINFO and PTRACE_SETSIGINFO from x86_64's sys32_ptrace. The generic compat_ptrace_request code handles these. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86 signals: lift set_fsRoland McGrath
This lifts the set_fs(USER_DS) call for signal handler setup out of the three places copying the same code into the one place that calls them all. There is no change in what it does. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86 signals: lift flags diddling codeRoland McGrath
This lifts the code diddling the TF and DF bits for signal handler setup out of the several places copying the same code into the one place that calls them all. There is no change in what it does. I also separated the recently-added DF bit clearing from the TF diddling. The compiler turns them back into one instruction anyway. The tossing in of DF to the same line of code with no new comments was a bit more arcane than seems wise. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: remove NexGen supportDmitri Vorobiev
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. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: array can become staticDmitri Vorobiev
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. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: remove unused function amd_init_cpu()Dmitri Vorobiev
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. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86-64: extend MCE CPU quirk handlingJan Beulich
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.

2008-04-26x86: fix watchdog ops for CoreDuoJan Beulich
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.

Jeff Chua reported that: Commit e40c0fe6b0b5dd16aec3c0dad311d36b19d78fd9 (x86: cleanup duplicate includes) turned the userspace asm-x86/posix_types.h and asm-x86/unistd.h headers into empty files.

2008-04-26V4L/DVB (7750): au0828/ cleanups and fixesAdrian Bunk
This patch contains the following cleanups and fixes: - "debug" is definitely not a good name for a global variable, renamed it to "au0828_debug" this fixes a compile error with some kernel configurations - since the module parameter is int the variable shouldn't be unsigned - remove the {usb,bridge,i2c}_debug module parameters since they are already covered by the "debug" module parameter - remove the unused au0828_bcount - make the needlessly global i2c_scan static - make the needlessly global dvb_register() static Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-26V4L/DVB (7748): tuner-core: some adjustments at tuner logs, if debug enabledMauro Carvalho Chehab
set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't reported. This patch changed set_addr printk to print a message only if set_addr is wrong. It also fix printk at set_type, since, if an attach were failing, nothing were reported. With the current code, working or not, a call to set_addr will produce a debug printk. also, set_type() were producing a false error message on tuner_xc2028, since it were requesting for setting a frequency on a place where firmware name weren't set yet.
