2011-03-25arm/gpio: Remove three copies of broken and racy debug codeThomas Gleixner3-129/+0
gpiolib plus two gpio implementations in arm fiddle in the guts of irq_desc in a racy and buggy way. Remove the stuff. I already told the gpio folks that we can provide that information in a proper way if necessary.

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.

2011-03-24SLUB: Write to per cpu data when allocating itChristoph Lameter1-1/+1
It turns out that the cmpxchg16b emulation has to access vmalloced percpu memory with interrupts disabled. If the memory has never been touched before then the fault necessary to establish the mapping will not to occur and the kernel will fail on boot. Fix that by reusing the CONFIG_PREEMPT code that writes the cpu number into a field on every cpu. Writing to the per cpu area before causes the mapping to be established before we get to a cmpxchg16b emulation.

2011-03-24autofs4: Do not potentially dereference NULL pointer returned by fget() in ↵Jesper Juhl1-0/+4
autofs_dev_ioctl_setpipefd() In fs/autofs4/dev-ioctl.c::autofs_dev_ioctl_setpipefd() we call fget(), which may return NULL, but we do not explicitly test for that NULL return so we may end up dereferencing a NULL pointer - bad. When I originally submitted this patch I had chosen EBUSY as the return value to use if this happens. Ian Kent was kind enough to explain why that would most likely be wrong and why EBADF should most likely be used instead. This version of the patch uses EBADF.

2011-03-24autofs4 - reinstate last used update on accessIan Kent2-34/+14
When direct (and offset) mounts were introduced the the last used timeout could no longer be updated in ->d_revalidate(). This is because covered direct mounts would be followed over without calling the autofs file system. As a result the definition of the busyness check for all entries was changed to be "actually busy" being an open file or working directory within the automount. But now we have a call back in the follow so the last used update on any access can be re-instated. This requires DCACHE_MANAGE_TRANSIT to always be set.
