2013-03-11xen/blkback: Change statistics counter types to unsignedZoltan Kiss3-16/+16
These values shouldn't be negative, but after an overflow their value can turn into negative, if they are signed. xentop can show bogus values in this case.

2013-03-11xen/blkback: correctly respond to unknown, non-native requestsDavid Vrabel3-4/+62
If the frontend is using a non-native protocol (e.g., a 64-bit frontend with a 32-bit backend) and it sent an unrecognized request, the request was not translated and the response would have the incorrect ID. This may cause the frontend driver to behave incorrectly or crash. Since the ID field in the request is always in the same place, regardless of the request type we can get the correct ID and make a valid response (which will report BLKIF_RSP_EOPNOTSUPP). This bug affected 64-bit SLES 11 guests when using a 32-bit backend. This guest does a BLKIF_OP_RESERVED_1 (BLKIF_OP_PACKET in the SLES source) and would crash in blkif_int() as the ID in the response would be invalid.

2013-03-11xen: arm: mandate EABI and use generic atomic operations.Ian Campbell2-22/+6
Rob Herring has observed that c81611c4e96f "xen: event channel arrays are xen_ulong_t and not unsigned long" introduced a compile failure when building without CONFIG_AEABI: /tmp/ccJaIZOW.s: Assembler messages: /tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]' Will Deacon pointed out that this is because OABI does not require even base registers for 64-bit values. We can avoid this by simply using the existing atomic64_xchg operation and the same containerof trick as used by the cmpxchg macros. However since this code is used on memory which is shared with the hypervisor we require proper atomic instructions and cannot use the generic atomic64 callbacks (which are based on spinlocks), therefore add a dependency on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much downside to this. While thinking about this we also observed that OABI has different struct alignment requirements to EABI, which is a problem for hypercall argument structs which are shared with the hypervisor and which must be in EABI layout. Since I don't expect people to want to run OABI kernels on Xen depend on CONFIG_AEABI explicitly too (although it also happens to be enforced by the !GENERIC_ATOMIC64 requirement too).

2013-03-11jbd2: fix use after free in jbd2_journal_dirty_metadata()Jan Kara1-5/+10
jbd2_journal_dirty_metadata() didn't get a reference to journal_head it was working with. This is OK in most of the cases since the journal head should be attached to a transaction but in rare occasions when we are journalling data, __ext4_journalled_writepage() can race with jbd2_journal_invalidatepage() stripping buffers from a page and thus journal head can be freed under hands of jbd2_journal_dirty_metadata(). Fix the problem by getting own journal head reference in jbd2_journal_dirty_metadata() (and also in jbd2_journal_set_triggers() which can possibly have the same issue).

2013-03-11staging: comedi: dt9812: use CR_CHAN() for channel numberIan Abbott1-6/+10
As pointed out by Dan Carpenper in <http://driverdev.linuxdriverproject.org/pipermail/devel/2013-February/036025.html>, the dt9812 comedi driver's use of the `chanspec` member of `struct comedi_insn` as a channel number is incorrect. Change it to use `CR_CHAN(insn->chanspec)` as the channel number (where `insn` is a pointer to the `struct comedi_insn` being processed).

2013-03-11ALSA: seq: Fix missing error handling in snd_seq_timer_open()Takashi Iwai1-4/+4
snd_seq_timer_open() didn't catch the whole error path but let through if the timer id is a slave. This may lead to Oops by accessing the uninitialized pointer.

2013-03-10ext4: reserve metadata block for every delayed writeLukas Czerner1-2/+61
Currently we only reserve space (data+metadata) in delayed allocation if we're allocating from new cluster (which is always in non-bigalloc file system) which is ok for data blocks, because we reserve the whole cluster. However we have to reserve metadata for every delayed block we're going to write because every block could potentially require metedata block when we need to grow the extent tree.

2013-03-10ext4: update reserved space after the 'correction'Lukas Czerner1-3/+9
Currently in ext4_ext_map_blocks() in delayed allocation writeback we would update the reservation and after that check whether we claimed cluster outside of the range of the allocation and if so, we'll give the block back to the reservation pool. However this also means that if the number of reserved data block dropped to zero before the correction, we would release all the metadata reservation as well, however we might still need it because the we're not done with the delayed allocation and there might be more blocks to come. This will result in error messages such as: EXT4-fs warning (device sdb): ext4_da_update_reserve_space:361: ino 12, allocated 1 with only 0 reserved metadata blocks (releasing 1 blocks with reserved 1 data blocks) This will only happen on bigalloc file system and it can be easily reproduced using fiemap-tester from xfstests like this: ./src/fiemap-tester -m DHDHDHDHD -S -p0 /mnt/test/file Or using xfstests such as 225. Fix this by doing the correction first and updating the reservation after that so that we do not accidentally decrease i_reserved_data_blocks to zero.

2013-03-11ARM: imx: pll1_sys should be an initial on clkShawn Guo1-1/+1
We always boot from PLL1, so let's have pll1_sys in the clks_init_on list to have clk prepare/enable use count match the hardware status, so that drivers managing pll1_sys like cpufreq can get the use count right from the start.

2013-03-10ext4: fix WARN_ON from ext4_releasepage()Jan Kara1-2/+2
ext4_releasepage() warns when it is passed a page with PageChecked set. However this can correctly happen when invalidate_inode_pages2_range() invalidates pages - and we should fail the release in that case. Since the page was dirty anyway, it won't be discarded and no harm has happened but it's good to be safe. Also remove bogus page_has_buffers() check - we are guaranteed page has buffers in this function.

2013-03-10Input: mms114 - Fix regulator enable and disable pathsMark Brown1-9/+25
When it uses regulators the mms114 driver checks to see if it managed to acquire regulators and ignores errors. This is not the intended usage and not great style in general. Since the driver already refuses to probe if it fails to allocate the regulators simply make the enable and disable calls unconditional and add appropriate error handling, including adding cleanup of the regulators if setup_reg() fails.
