2011-03-25MIPS: MSP71xx: Add vectored interrupt support.Anoop P A4-88/+397
This patch will add vectored interrupt setups required for MIPS MT modes. irq_cic has been restructured and moved per irq handler to different file. irq_cic has been re wrote to support mips MT modes ( VSMP / SMTC ) [Ralf: fixed some more checkpatch warnings.] Signed-off-by: Anoop P A <[email protected]> To: [email protected] To: [email protected] To: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/2041/ Signed-off-by: Ralf Baechle <[email protected]>

2011-03-25perf, x86: Complain louder about BIOSen corrupting CPU/PMU state and continueIngo Molnar1-2/+7
Eric Dumazet reported that hardware PMU events do not work on his system, due to the BIOS corrupting PMU state: Performance Events: PEBS fmt0+, Core2 events, Broken BIOS detected, using software events only. [Firmware Bug]: the BIOS has corrupted hw-PMU resources (MSR 186 is 43003c) Linus suggested that we continue in the face of such BIOS-induced CPU state corruption: http://lkml.org/lkml/2011/3/24/608 Such BIOSes will have to be fixed - Linux developers rely on a working and fully capable PMU and the BIOS interfering with the CPU's PMU state is simply not acceptable. So this patch changes perf to continue when it detects such BIOS interaction, some hardware events may be unreliable due to the BIOS writing and re-writing them - there's not much the kernel can do about that but to detect the corruption and report it.

2011-03-25m68k: merge m68k and m68knommu arch directoriesGreg Ungerer170-7131/+6916
There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King <[email protected]>, which was originally written by Arnd Bergmann <[email protected]>. > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > <file>_mm.<ext> and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed <file>_no.<ext> and a small > wrapper file <file>.<ext> is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include <file>_mm.<ext> > #else > #include <file>_no.<ext> > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches. Signed-off-by: Greg Ungerer <[email protected]>
2011-03-24lib, arch: add filter argument to show_mem and fix private implementationsDavid Rientjes8-8/+8
Commit ddd588b5dd55 ("oom: suppress nodes that are not allowed from meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which resulted in build warnings on all architectures that implement their own versions of show_mem(): lib/lib.a(show_mem.o): In function `show_mem': show_mem.c:(.text+0x1f4): multiple definition of `show_mem' arch/sparc/mm/built-in.o:(.text+0xd70): first defined here The fix is to remove __show_mem() and add its argument to show_mem() in all implementations to prevent this breakage. Architectures that implement their own show_mem() actually don't do anything with the argument yet, but they could be made to filter nodes that aren't allowed in the current context in the future just like the generic implementation.

2011-03-24sparc32: Fix multiple RTC detections on SUN4DKjetil Oftedal1-0/+4
During the preparation for testing the recent changes made to the SUN4D specific code in the kernel by Sam Ravnborg the following was discovered: Since the removal of of_platform_bus_type (commit: eca3930163ba8884060ce9d9ff5ef0d9b7c7b00f ) multiboard SUN4Ds have not been able to boot. The kernel crashes due to a zero-pointer error encountered when registering multiple M48T59 RTCs (There is one on each board). A patch for the was previously submitted, but the problem was not a serious at that time, as it would only generate warnings. Now the kernel will crash and stop executing before the serial console has been started.

2011-03-24x86: DT: Cleanup namespace and call irq_set_irq_type() unconditionalThomas Gleixner1-3/+1
That call escaped the name space cleanup. Fix it up. We really want to call there. The chip might have changed since the irq was setup initially. So let the core code and the chip decide what to do. The status is just an unreliable snapshot. Signed-off-by: Thomas Gleixner <[email protected]> Cc: Sebastian Andrzej Siewior <[email protected]>
2011-03-24x86: DT: Fix return condition in irq_create_of_mapping()Thomas Gleixner1-1/+1
The xlate() function returns 0 or a negative error code. Returning the error code blindly will be seen as an huge irq number by the calling function because irq_create_of_mapping() returns an unsigned value. Return 0 (NO_IRQ) as required.

2011-03-24perf, x86: P4 PMU - Read proper MSR register to catch unflagged overflowsDon Zickus1-0/+1
The read of a proper MSR register was missed and instead of counter the configration register was tested (it has ARCH_P4_UNFLAGGED_BIT always cleared) leading to unknown NMI hitting the system. As result the user may obtain "Dazed and confused, but trying to continue" message. Fix it by reading a proper MSR register. When an NMI happens on a P4, the perf nmi handler checks the configuration register to see if the overflow bit is set or not before taking appropriate action. Unfortunately, various P4 machines had a broken overflow bit, so a backup mechanism was implemented. This mechanism checked to see if the counter rolled over or not. A previous commit that implemented this backup mechanism was broken. Instead of reading the counter register, it used the configuration register to determine if the counter rolled over or not. Reading that bit would give incorrect results. This would lead to 'Dazed and confused' messages for the end user when using the perf tool (or if the nmi watchdog is running). The fix is to read the counter register before determining if the counter rolled over or not.

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6 * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: deal with races in /proc/*/{syscall,stack,personality} proc: enable writing to /proc/pid/mem proc: make check_mem_permission() return an mm_struct on success proc: hold cred_guard_mutex in check_mem_permission() proc: disable mem_write after exec mm: implement access_remote_vm mm: factor out main logic of access_process_vm mm: use mm_struct to resolve gate vma's in __get_user_pages mm: arch: rename in_gate_area_no_task to in_gate_area_no_mm mm: arch: make in_gate_area take an mm_struct instead of a task_struct mm: arch: make get_gate_vma take an mm_struct instead of a task_struct x86: mark associated mm when running a task in 32 bit compatibility mode x86: add context tag to mark mm when running a task in 32-bit compatibility mode auxv: require the target to be tracable (or yourself) close race in /proc/*/environ report errors in /proc/*/*map* sanely pagemap: close races with suid execve make sessionid permissions in /proc/*/task/* match those in /proc/* fix leaks in path_lookupat() Fix up trivial conflicts in fs/proc/base.c
