Commit d065bd810b6deb67d4897a14bfe21f8eb526ba99 (mm: retry page fault when blocking on disk transfer) and commit 37b23e0525d393d48a7d59f870b3bc061a30ccdb (x86,mm: make pagefault killable) The above commits introduced changes into the x86 pagefault handler for making the page fault handler retryable as well as killable. These changes reduce the mmap_sem hold time, which is crucial during OOM killer invocation. Port these changes to openrisc. Signed-off-by: Mohd.

2012-05-06Btrfs: avoid sleeping in verify_parent_transid while atomicChris Mason5-17/+34
verify_parent_transid needs to lock the extent range to make sure no IO is underway, and so it can safely clear the uptodate bits if our checks fail. But, a few callers are using it with spinlocks held. Most of the time, the generation numbers are going to match, and we don't want to switch to a blocking lock just for the error case. This adds an atomic flag to verify_parent_transid, and changes it to return EAGAIN if it needs to block to properly verifiy things. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2012-05-05TTY: pdc_cons, fix regression in closeJiri Slaby1-1/+1
The test in pdc_console_tty_close '!tty->count' was always wrong because tty->count is decremented after tty->ops->close is called and thus can never be zero. Hence the 'then' branch was never executed and the timer never deleted. This did not matter until commit 5dd5bc40f3b6 ("TTY: pdc_cons, use tty_port"). There we needed to set TTY in tty_port to NULL, but this never happened due to the bug above. So change the test to really trigger at the last close by changing the condition to 'tty->count == 1'. Well, the driver should not touch tty->count at all. It should use tty_port->count and count open count there itself.

2012-05-05init: don't try mounting device as nfs root unless type fully matchesSasha Levin1-1/+1
Currently, we'll try mounting any device who's major device number is UNNAMED_MAJOR as NFS root. This would happen for non-NFS devices as well (such as 9p devices) but it wouldn't cause any issues since mounting the device as NFS would fail quickly and the code proceeded to doing the proper mount: [ 101.522716] VFS: Unable to mount root fs via NFS, trying floppy. [ 101.534499] VFS: Mounted root (9p filesystem) on device 0:18. Commit 6829a048102a ("NFS: Retry mounting NFSROOT") introduced retries when mounting NFS root, which means that now we don't immediately fail and instead it takes an additional 90+ seconds until we stop retrying, which has revealed the issue this patch fixes. This meant that it would take an additional 90 seconds to boot when we're not using a device type which gets detected in order before NFS. This patch modifies the NFS type check to require device type to be 'Root_NFS' instead of requiring the device to have an UNNAMED_MAJOR major. This makes boot process cleaner since we now won't go through the NFS mounting code at all when the device isn't an NFS root ("/dev/nfs").

2012-05-05ACPI: Fix D3hot v D3cold confusionLin Ming4-16/+14
Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot in some places, but D3cold in other places. After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD; and all references to D3hot use ACPI_STATE_D3_HOT. ACPI's _PR3 method is used to enter both D3hot and D3cold states. What distinguishes D3hot from D3cold is the presence _PR3 (Power Resources for D3hot) If these resources are all ON, then the state is D3hot. If _PR3 is not present, or all _PR0 resources for the devices are OFF, then the state is D3cold. This patch applies after Linux-3.4-rc1. A future syntax cleanup may remove ACPI_STATE_D3 to emphasize that it always means ACPI_STATE_D3_COLD. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Acked-by: Rafael J.

2012-05-04seqlock: add 'raw_seqcount_begin()' functionLinus Torvalds1-0/+21
The normal read_seqcount_begin() function will wait for any current writers to exit their critical region by looping until the sequence count is even. That "wait for sequence count to stabilize" is the right thing to do if the read-locker will just retry the whole operation on contention: no point in doing a potentially expensive reader sequence if we know at the beginning that we'll just end up re-doing it all. HOWEVER. Some users don't actually retry the operation, but instead will abort and do the operation with proper locking. So the sequence count case may be the optimistic quick case, but in the presense of writers you may want to do full locking in order to guarantee forward progress. The prime example of this would be the RCU name lookup. And in that case, you may well be better off without the "retry early", and are in a rush to instead get to the failure handling. Thus this "raw" interface that just returns the sequence number without testing it - it just forces the low bit to zero so that read_seqcount_retry() will always fail such a "active concurrent writer" scenario. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-05-04Fix __read_seqcount_begin() to use ACCESS_ONCE for sequence value readLinus Torvalds1-1/+1
We really need to use a ACCESS_ONCE() on the sequence value read in __read_seqcount_begin(), because otherwise the compiler might end up reloading the value in between the test and the return of it. As a result, it might end up returning an odd value (which means that a write is in progress). If the reader is then fast enough that that odd value is still the current one when the read_seqcount_retry() is done, we might end up with a "successful" read sequence, even despite the concurrent write being active. In practice this probably never really happens - there just isn't anything else going on around the read of the sequence count, and the common case is that we end up having a read barrier immediately afterwards. So the code sequence in which gcc might decide to reaload from memory is small, and there's no reason to believe it would ever actually do the reload. But if the compiler ever were to decide to do so, it would be incredibly annoying to debug. Let's just make sure. Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

It seems that there was an error with the active_low = 1 for the LED, since it should be set to 0 (meaning that active is high, since 0 is false, hence the confusion. The wiki article about it confuses it, since it contradicts itself, regarding what turns on the LED. I have tested 3.4-rc2 on my net5501 with this patch, and it makes the LED behave correctly, where "none" turns it off, and "default-on" turns it on, when echoed onto the trigger "file" in /sys/class/leds.

2012-05-03vfs: make word-at-a-time accesses handle a non-existing pageLinus Torvalds4-7/+58
It turns out that there are more cases than CONFIG_DEBUG_PAGEALLOC that can have holes in the kernel address space: it seems to happen easily with Xen, and it looks like the AMD gart64 code will also punch holes dynamically. Actually hitting that case is still very unlikely, so just do the access, and take an exception and fix it up for the very unlikely case of it being a page-crosser with no next page. And hey, this abstraction might even help other architectures that have other issues with unaligned word accesses than the possible missing next page. IOW, this could do the byte order magic too. Peter Anvin fixed a thinko in the shifting for the exception case.

2012-05-03cifs - check S_AUTOMOUNT in revalidateIan Kent1-5/+12
When revalidating a dentry, if the inode wasn't known to be a dfs entry when the dentry was instantiated, such as when created via ->readdir(), the DCACHE_NEED_AUTOMOUNT flag needs to be set on the dentry in ->d_revalidate(). The false return from cifs_d_revalidate(), due to the inode now being marked with the S_AUTOMOUNT flag, might not invalidate the dentry if there is a concurrent unlazy path walk. This is because the dentry reference count will be at least 2 in this case causing d_invalidate() to return EBUSY. So the asumption that the dentry will be discarded then correctly instantiated via ->lookup() might not hold.
