Also update comments and assertions in io.h: - EF10 does not have a general BIU collector and does not have the bug affecting TIMER_COMMAND_REG[0] on Falcon/Siena - The WPTR field moved within RX_DESC_UPD_REG and TX_DESC_UPD_REG.

2013-08-29sfc: Extend struct efx_tx_buffer to allow pushing option descriptorsBen Hutchings
The TX path firmware for EF10 supports 'option descriptors' to control offloads and various other features. Add a flag and field for these in struct efx_tx_buffer, and don't treat them as DMA descriptors on completion. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2013-08-29sfc: Use a global count of active queues instead of pending drainsAlexandre Rames
On EF10, the firmware will initiate a queue flush in certain error cases. We need to accept that flush events might appear at any time after a queue has been initialised, not just when we try to flush them. We can handle Falcon-architecture in just the same way.

2013-08-29sfc: Prepare for RX scatter on EF10Jon Cooper
RX DMA scatter is always enabled on EF10. Adjust the common RX completion handling to allow for this. RX completion events on EF10 include the length used from a single descriptor, not the cumulative length used. Add a field to struct efx_rx_queue to hold the cumulative length.

2013-08-29irqchip: sirf: move from legacy mode to linear irqdomainBarry Song
the series of patches for irqdomain core in 3.11 has broken sirf irq which uses legacy mapping. all users fail in the new kernel while setupping irq. this patch moves to linear irqdomain and drop old legacy irqdomain codes since we don't need it any more, and at the same time, it also fixes the broken interrupts of sirfsoc in 3.11. on the other hand, we actually only have 64 interrupt sources for prima2 and atlas6, but there are 128 interrupt souces for marco which uses GIC. in the legacy codes, sirf gpio also uses legacy irqdomain, so to make gpio interrupt mapping not depend on the prima2/atlas6/marco an use unified marco,we enlarge prima2/atlas6 interrupt number to 128. here we don't need this workaround any more as sirf gpio also moved to linear mode before. so we move SIRFSOC_NUM_IRQS back to 64 too.

2013-08-29ASoC: Samsung: Do not queue cyclic buffers multiple timesTomasz Figa
The legacy S3C-DMA API required every period of a cyclic buffer to be queued separately. After conversion of Samsung ASoC to Samsung DMA wrappers somebody made an assumption that the same is needed for DMA engine API, which is not true. In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer multiple times with a shift of one period per iteration, leading to: a) severe memory waste - up to 13x times more DMA transfer descriptors are allocated than needed, b) possible memory corruption, because further cyclic buffers were out of the original buffers, due to the offset. This patch fixes this problem by making the legacy S3C-DMA API use the same semantics as DMA engine (the whole cyclic buffer is enqueued at once) and modifying users of Samsung DMA wrappers in cyclic mode to behave appropriately.

2013-08-29xfs: don't account buffer cancellation during log recovery readaheadDave Chinner
When doing readhaead in log recovery, we check to see if buffers are cancelled before doing readahead. If we find a cancelled buffer, however, we always decrement the reference count we have on it, and that means that readahead is causing a double decrement of the cancelled buffer reference count. This results in log recovery *replaying cancelled buffers* as the actual recovery pass does not find the cancelled buffer entry in the commit phase of the second pass across a transaction. On debug kernels, this results in an ASSERT failure like so: XFS: Assertion failed: !(flags & XFS_BLF_CANCEL), file: fs/xfs/xfs_log_recover.c, line: 1815 xfstests generic/311 reproduces this ASSERT failure with 100% reproducability. Fix it by making readahead only peek at the buffer cancelled state rather than the full accounting that xlog_check_buffer_cancelled() does.

2013-08-29cgroup: fix rmdir EBUSY regression in 3.11Hugh Dickins
On 3.11-rc we are seeing cgroup directories left behind when they should have been removed. Here's a trivial reproducer: cd /sys/fs/cgroup/memory mkdir parent parent/child; rmdir parent/child parent rmdir: failed to remove `parent': Device or resource busy It's because cgroup_destroy_locked() (step 1 of destruction) leaves cgroup on parent's children list, letting cgroup_offline_fn() (step 2 of destruction) remove it; but step 2 is run by work queue, which may not yet have removed the children when parent destruction checks the list. Fix that by checking through a non-empty list of children: if every one of them has already been marked CGRP_DEAD, then it's safe to proceed: those children are invisible to userspace, and should not obstruct rmdir. (I didn't see any reason to keep the cgrp->children checks under the unrelated css_set_lock, so moved them out.) tj: Flattened nested ifs a bit and updated comment so that it's correct on both for-3.11-fixes and for-3.12.
