2013-05-25ARM: SAMSUNG: Add names to fimd0 IRQ resourcesTomasz Figa1-3/+3
Since commit 1977e6d8 (drm/exynos: change the method for getting the interrupt) the Exynos DRM FIMD driver requires IRQ resources to be named. This patch fixes probe failure in non-DT cases by adding appropriate resource names to fimd0 platform device.

2013-05-24xfs: remote attribute lookups require the value lengthDave Chinner1-1/+2
When reading a remote attribute, to correctly calculate the length of the data buffer for CRC enable filesystems, we need to know the length of the attribute data. We get this information when we look up the attribute, but we don't store it in the args structure along with the other remote attr information we get from the lookup. Add this information to the args structure so we can use it appropriately.

2013-05-24xfs: fix missing KM_NOFS tags to keep lockdep happyDave Chinner4-5/+7
There are several places where we use KM_SLEEP allocation contexts and use the fact that they are called from transaction context to add KM_NOFS where appropriate. Unfortunately, there are several places where the code makes this assumption but can be called from outside transaction context but with filesystem locks held. These places need explicit KM_NOFS annotations to avoid lockdep complaining about reclaim contexts.

2013-05-24parisc: fix irq stack on UP and SMPHelge Deller3-41/+26
The logic to detect if the irq stack was already in use with raw_spin_trylock() is wrong, because it will generate a "trylock failure on UP" error message with CONFIG_SMP=n and CONFIG_DEBUG_SPINLOCK=y. arch_spin_trylock() can't be used either since in the CONFIG_SMP=n case no atomic protection is given and we are reentrant here. A mutex didn't worked either and brings more overhead by turning off interrupts. So, let's use the fastest path for parisc which is the ldcw instruction. Counting how often the irq stack was used is pretty useless, so just drop this piece of code. Signed-off-by: Helge Deller <[email protected]>

2013-05-24xfs: fix rounding in xfs_free_file_spaceDave Chinner1-2/+2
The offset passed into xfs_free_file_space() needs to be rounded down to a certain size, but the rounding mask is built by a 32 bit variable. Hence the mask will always mask off the upper 32 bits of the offset and lead to incorrect writeback and invalidation ranges. This is not actually exposed as a bug because we writeback and invalidate from the rounded offset to the end of the file, and hence the offset we are actually punching a hole out of will always be covered by the code. This needs fixing, however, if we ever want to use exact ranges for writeback/invalidation here...

2013-05-24xfs: fix sub-page blocksize data integrity writesDave Chinner1-0/+19
FSX on 512 byte block size filesystems has been failing for some time with corrupted data. The fault dates back to the change in the writeback data integrity algorithm that uses a mark-and-sweep approach to avoid data writeback livelocks. Unfortunately, a side effect of this mark-and-sweep approach is that each page will only be written once for a data integrity sync, and there is a condition in writeback in XFS where a page may require two writeback attempts to be fully written. As a result of the high level change, we now only get a partial page writeback during the integrity sync because the first pass through writeback clears the mark left on the page index to tell writeback that the page needs writeback.... The cause is writing a partial page in the clustering code. This can happen when a mapping boundary falls in the middle of a page - we end up writing back the first part of the page that the mapping covers, but then never revisit the page to have the remainder mapped and written. The fix is simple - if the mapping boundary falls inside a page, then simple abort clustering without touching the page. This means that the next ->writepage entry that write_cache_pages() will make is the page we aborted on, and xfs_vm_writepage() will map all sections of the page correctly. This behaviour is also optimal for non-data integrity writes, as it results in contiguous sequential writeback of the file rather than missing small holes and having to write them a "random" writes in a future pass. With this fix, all the fsx tests in xfstests now pass on a 512 byte block size filesystem on a 4k page machine.

2013-05-24parisc: make interrupt and interruption stack allocation reentrantJohn David Anglin2-10/+10
The get_stack_use_cr30 and get_stack_use_r30 macros allocate a stack frame for external interrupts and interruptions requiring a stack frame. They are currently not reentrant in that they save register context before the stack is set or adjusted. I have observed a number of system crashes where there was clear evidence of stack corruption during interrupt processing, and as a result register corruption. Some interruptions can still occur during interruption processing, however external interrupts are disabled and data TLB misses don't occur for absolute accesses. So, it's not entirely clear what triggers this issue. Also, if an interruption occurs when Q=0, it is generally not possible to recover as the shadowed registers are not copied. The attached patch reworks the get_stack_use_cr30 and get_stack_use_r30 macros to allocate stack before doing register saves. The new code is a couple of instructions shorter than the old implementation. Thus, it's an improvement even if it doesn't fully resolve the stack corruption issue. Based on limited testing, it improves SMP system stability. Signed-off-by: John David Anglin <[email protected]> Signed-off-by: Helge Deller <[email protected]>

2013-05-24GFS2: Use single-block reservations for directoriesBob Peterson1-2/+7
This patch changes the multi-block allocation code, such that directory inodes only get a single block reserved in the bitmap. That way, the bitmaps are more tightly packed together, and there are fewer spans of free blocks for in-use block reservations. This means it takes less time to find a free span of blocks in the bitmap, which speeds things up. This increases the performance of some workloads by almost 2X. In Nate's mockup.py script (which does (1) create dir, (2) create dir in dir, (3) create file in that dir) the test executes in 23 steps rather than 43 steps, a 47% performance improvement.

2013-05-24drivers/crypto/nx: Fixes for multiple races and issuesKent Yoder6-38/+19
Fixes a race on driver init with registering algorithms where the driver status flag wasn't being set before self testing started. Added the cra_alignmask field for CBC and ECB modes. Fixed a bug in GCM where AES block size was being used instead of authsize. Removed use of blkcipher_walk routines for scatterlist processing. Corner cases in the code prevent us from processing an entire scatterlist at a time and walking the buffers in block sized chunks turns out to be unecessary anyway. Fixed off-by-one error in saving off extra data in the sha code. Fixed accounting error for number of bytes processed in the sha code.

2013-05-23be2net: bug fix on returning an invalid nic descriptorWei Yang1-9/+4
In function be_get_nic_desc(), it will go through the descriptor array returned from f/w. By comparing the desc_type field, it determines whether there is a nic descriptor in the array or not. In the case of no nic descriptor, this function should return NULL. The code may return an invalide descriptor, when there is no nic descriptor in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case, even there is no nic descriptor, it will still return the lase descriptor since the i doesn't equal to MAX_RESOURCE_DESC. This patch fix this issue by returning the descriptor when find it and return NULL for other cases.

2013-05-23tcp: xps: fix reordering issuesEric Dumazet1-4/+6
commit 3853b5841c01a ("xps: Improvements in TX queue selection") introduced ooo_okay flag, but the condition to set it is slightly wrong. In our traces, we have seen ACK packets being received out of order, and RST packets sent in response. We should test if we have any packets still in host queue.
