DPLL1 reprogramming to a different rate is actually blocked inside
omap1_select_table_rate(), resulting in the defalut rate of 60 MHz
always used instead of the one selected in .config. OTOH, in
omap1_defconfig we currently rely on Kconfig options for the supported
MHz rates in case of boards which boot with dpll1 not set correctly by
their boot loaders.
This means that before we allow for reprogramming of dpll1 rate, we
should remove all unsafe clock selections from omap1_defconfig,
otherwise it will stop booting on boards with imperfect boot loaders,
as it would always try to change to 216MHz.
Keep only one safe clock rate per each supported xtal frequency, i.e.
60MHZ dpll1 for 12MHz xtal and 182MHz dpll1 for 13MHz xtal.
BTW, this change goes into the direction of removing all OMAP1 clock
rate options, planned for next merge window.

Commit
e9b7086b80c4d9e354f4edc9e280ae85a60df408 (ARM: OMAP: Fix
reprogramming of dpll1 rate) fixed a regression for systems that
did not rely on bootloader set rates.
However, it also introduced a new problem where the rates selected
in .config would not take affect as omap1_select_table_rate
currently refuses to reprogram DPLL1 if it's already initialized.
This was not a problem earlier, as the reprogramming was done
earlier with ck_dpll1_p->rate uninitialized.
Fix this by forcing the reprogramming on systems booting at rates
below 60MHz. Note that the long term fix is to make the rates
SoC specific later on.

ocfs2: avoid unaligned access to dqc_bitmap
The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned,
but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(),
ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These
are wrapper macros for ext2_*_bit() which need to take an unsigned long
aligned address (though some architectures are able to handle unaligned
address correctly)
So some 64bit architectures may not be able to access the dqc_bitmap
correctly.
This avoids such unaligned access by using another wrapper functions for
ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to
handle unaligned bitmap access.

Commit
4a54c8c16 introduced raid-repair, killing the individual

4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to
disk-io.c.
The raid-repair commit had logic to disable raid-repair, if
readpage_io_failed_hook is set. Thus, the readahead commit effectively
disabled raid-repair for meta data.
This commit changes the logic to always attempt raid-repair when needed and
call the readpage_io_failed_hook in case raid-repair fails. This is much
more straight forward and should have been like that from the beginning.

ARM: 7181/1: Restrict kprobes probing SWP instructions to ARMv5 and below
The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be
UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a
SWP instruction will cause an oops when the kprobes emulation code
executes an undefined instruction.
As the SWP instruction should be rare or non-existent in kernels for
ARMv6 and later, we can simply avoid these problems by not allowing
probing of these.

ARM: 7180/1: Change kprobes testcase with unpredictable STRD instruction
There is a kprobes testcase for the instruction "strd r2, [r3], r4".
This has unpredictable behaviour as it uses r3 for register writeback
addressing and also stores it to memory.
On a cortex A9, this testcase would fail because the instruction writes
the updated value of r3 to memory, whereas the kprobes emulation code
writes the original value.
Fix this by changing testcase to used r5 instead of r3.

Btrfs: reset cluster's max_size when creating bitmap
The field that indicates the size of the largest contiguous chunk of
free space in the cluster is not initialized when setting up bitmaps,
it's only increased when we find a larger contiguous chunk. We end up
retaining a larger value than appropriate for highly-fragmented
clusters, which may cause pointless searches for large contiguous
groups, and even cause clusters that do not meet the density
requirements to be set up.

Btrfs: initialize new bitmaps' list
We're failing to create clusters with bitmaps because
setup_cluster_no_bitmap checks that the list is empty before inserting
the bitmap entry in the list for setup_cluster_bitmap, but the list
field is only initialized when it is restored from the on-disk free
space cache, or when it is written out to disk.
Besides a potential race condition due to the multiple use of the list
field, filesystem performance severely degrades over time: as we use
up all non-bitmap free extents, the try-to-set-up-cluster dance is
done at every metadata block allocation. For every block group, we
fail to set up a cluster, and after failing on them all up to twice,
we fall back to the much slower unclustered allocation.
To make matters worse, before the unclustered allocation, we try to
create new block groups until we reach the 1% threshold, which
introduces additional bitmaps and thus block groups that we'll iterate
over at each metadata block request.

Btrfs: fix deadlock on metadata reservation when evicting a inode
When I ran the xfstests, I found the test tasks was blocked on meta-data
reservation.
By debugging, I found the reason of this bug:
start transaction

v
reserve meta-data space
|
v
flush delay allocation -> iput inode -> evict inode
^ |
| v
wait for delay allocation flush <- reserve meta-data space
And besides that, the flush on evicting inode will block the thread, which
is reclaiming the memory, and make oom happen easily.
Fix this bug by skipping the flush step when evicting inode.

Coinciding with stack trace is the following message:
ib0: ib_address_create failed
The code below in ipoib_mcast_join_finish() will note the above
failure in the address handle but otherwise continue:
ah = ipoib_create_ah(dev, priv->pd, &av);
if (!ah) {
ipoib_warn(priv, "ib_address_create failed\n");
} else {
The while loop at the bottom of ipoib_mcast_join_finish() will attempt
to send queued multicast packets in mcast->pkt_queue and eventually
end up in ipoib_mcast_send():
if (!mcast->ah) {
if (skb_queue_len(&mcast->pkt_queue) < IPOIB_MAX_MCAST_QUEUE)
skb_queue_tail(&mcast->pkt_queue, skb);
else {
++dev->stats.tx_dropped;
dev_kfree_skb_any(skb);
}
My read is that the code will requeue the packet and return to the
ipoib_mcast_join_finish() while loop and the stage is set for the
"hung" task diagnostic as the while loop never sees a non-NULL ah, and
will do nothing to resolve.
There are GFP_ATOMIC allocates in the provider routines, so this is
possible and should be dealt with.
The test that induced the failure is associated with a host SM on the
same server during a shutdown.
This patch causes ipoib_mcast_join_finish() to exit with an error
which will flush the queued mcast packets. Nothing is done to unwind
the QP attached state so that subsequent sends from above will retry
the join.

already. Otherwise, we end up retrying with MPAv1 even when its not
needed on getting peer aborts - and this could lead to kernel panic.

RDMA/cxgb4: Fix iw_cxgb4 count_rcqes() logic
Fix another place in the code where logic dealing with the t4_cqe was
using the wrong QID. This fixes the counting logic so that it tests
against the SQ QID instead of the RQ QID when counting RCQES.

regulator: twl: fix twl4030 support for smps regulators
SMPS regulator voltage control differs from the one of the LDO ones.
Current TWL code was using LDO regulator ops for controlling the SMPS
regulators, which fails. This was fixed fixed by adding separate
regulator type which uses correct logic and calculations for the
voltage levels.

genirq: fix regression in irqfixup, irqpoll
Commit
fa27271bc8d2("genirq: Fixup poll handling") introduced a
regression that broke irqfixup/irqpoll for some hardware configurations.
Amidst reorganizing 'try_one_irq', that patch removed a test that
checked for 'action->handler' returning IRQ_HANDLED, before acting on
the interrupt. Restoring this test back returns the functionality lost
since 2.6.39. In the current set of tests, after 'action' is set, it
must precede '!action->next' to take effect.
With this and my previous patch to irq/spurious.c,
c75d720fca8a, all
IRQ regressions that I have encountered are fixed.

regulator: fix use after free bug
This is caused by dereferencing 'rdev' after device_unregister() in
the regulator_unregister() function. 'rdev' is freed by
device_unregister(), so it must not be dereferenced after this call.

ALSA: hda - Fix jack-detection control of VT1708
VT1708 has no support for unsolicited events per jack-plug, the driver
implements the workq for polling the jack-detection. The mixer element
"Jack Detect" was supposed to control this behavior on/off, but this
doesn't work properly as is now. The workq is always started and the
HP automute is always enabled.
This patch fixes the jack-detect control behavior by triggering / stopping
the work appropriately at the state change. Also the work checks the
internal state to continue scheduling or not.
