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.

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.

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.

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.

2008-04-26agp: convert drivers/char/agp/frontend.c to use unlocked_ioctlMathieu Segaud
As of now, agp_compat_ioctl already runs without the BKL. Mutual exclusion is enforced by agp_fe.agp_mutex in agp_ioctl() and agp_compat_ioctl(). Apply the same locking rationale to the two functions allowing BKL cleanup.
