It looks that the warning is caused by that twd_update_frequency() gets
called from an atomic context while it calls clk_get_rate() where a
mutex gets held.

To fix the warning, let's convert common clk users over to clk notifiers
in place of CPUfreq notifiers.  This works out nicely for Cortex-A9
MPcore designs that scale all CPUs at the same frequency.

Platforms that have not been converted to the common clk framework and
support CPUfreq will rely on the old mechanism.  Once these platforms
are converted over fully then we can remove the CPUfreq-specific bits
for good.

Note that you could already do the same thing with "fstatat()" and an

there is no reason not to just allow it directly.

Tyler Hicks [Thu, 13 Sep 2012 19:00:56 +0000 (12:00 -0700)]
eCryptfs: Copy up attributes of the lower target inode after rename

After calling into the lower filesystem to do a rename, the lower target
inode's attributes were not copied up to the eCryptfs target inode. This
resulted in the eCryptfs target inode staying around, rather than being
evicted, because i_nlink was not updated for the eCryptfs inode. This
also meant that eCryptfs didn't do the final iput() on the lower target
inode so it stayed around, as well. This would result in a failure to
free up space occupied by the target file in the rename() operation.
Both target inodes would eventually be evicted when the eCryptfs
filesystem was unmounted.

This patch calls fsstack_copy_attr_all() after the lower filesystem
does its ->rename() so that important inode attributes, such as i_nlink,
are updated at the eCryptfs layer. ecryptfs_evict_inode() is now called
and eCryptfs can drop its final reference on the lower inode.

821f749 eCryptfs: Revert to a writethrough cache model

necessary to properly handle open() -> mmap() -> close() -> dirty pages
-> munmap(), because the lower file could be closed before the dirty

Rather than reapplying 32001d6f, this approach is a better way of
ensuring that the lower file is still open in order to handle writing
out the dirty pages. It is called from ecryptfs_release(), while we have
a lock on the lower file pointer, just before the lower file gets the

  commit 230718bd net: qmi_wwan: bind to both control and data interface

either a single combined interface function, or no subdriver at all.

The result was that we called into the subdriver both when the

GFS2: Take account of blockages when using reserved blocks

The claim_reserved_blks() function was not taking account of
the possibility of "blockages" while performing allocation.
This can be caused by another node allocating something in
the same extent which has been reserved locally.

This patch tests for this condition and then skips the remainder
of the reservation in this case. This is a relatively rare event,
so that it should not affect the general performance improvement
which the block reservations provide.

usb: chipidea: udc: don't stall endpoint if request list is empty in isr_tr_complete_low

starting a rndis connection we see this message every 4-10 seconds:

    g_ether gadget: high speed config #2: RNDIS

Analysis shows that each time this message is printed, the rndis connection is
re-establish due to a reset because of a stalled endpoint (ep 0, dir 1). The
endpoint is stalled because the reqeust complete bit on that endpoint is set,
but in isr_tr_complete_low() the endpoint request list (mEp->qh.queue) is
empty.

This patch removed this check, because the code doesn't take the following
situation into account:

The loop over all endpoints in isr_tr_complete_handler() will call ep_nuke() on
both ep0/dir0 and ep/dir1 in the first loop. Pending reqeusts will be flushed
and completed here. There seems to be a race condition, the request is nuked,
but the request complete bit will be set, too. The subsequent check (in
ep0/dir1's loop cycle) for endpoint request list (mEp->qh.queue) empty will
fail.

Both other mainline chipidea drivers (mv_udc_core.c and fsl_udc_core.c) don't
have this check.

i2c: pnx: Fix read transactions of >= 2 bytes

On transactions with n>=2 bytes, the controller actually wrongly clocks in n+1
bytes. This is caused by the (wrong) assumption that RFE in the Status Register
is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to
the implementation of synchronized byte ordering, e.g.:

Dummy-TX - RX - Dummy-TX - RX - ...

But since RFE actually stays high after some Dummy-TX, it rather looks like:

Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX)

The last RX byte is clocked in by the bus controller, but ignored by the kernel
when filling the userspace buffer.

This patch fixes the issue by asking for RX via Dummy-TX asynchronously.

("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern")

Do so.

Use KERN_SOH and string concatenation instead of "%c" KERN_SOH_ASCII

hwmon: (ina2xx) Fix word size register read and write operations

The driver uses be16_to_cpu and cpu_to_be16 to convert data in SMBus word
operations from chip to host byte order. However, the data passed from and to
the SMBus word API functions is in host byte order, not in chip byte order.
Conversion should therefore use swab16 instead of be16 to change the byte order.

Replace driver internal word conversion functions with SMBus API functions to
solve the problem.

 "It's later than I'd like but well the timing just didn't work out this
  time.

  There are three bug fixes.  One from before 3.6-rc1 and two from the
  new CPU hotplug code.  Kudos to Lai for discovering all of them and
  providing fixes.

   * Atomicity bug when clearing a flag and setting another.  The two
     operation should have been atomic but wasn't.  This bug has existed
     for a long time but is unlikely to have actually happened.  Fix is
     safe.  Marked for -stable.

   * If CPU hotplug cycles happen back-to-back before workers finish the
     previous cycle, the states could get out of sync and it could get
     stuck.  Fixed by waiting for workers to complete before finishing
     hotplug cycle.

   * While CPU hotplug is in progress, idle workers could be depleted
     which can then lead to deadlock.  I think both happening together
     is highly unlikely but still better to fix it and the fix isn't too
     scary.

  There's another workqueue related regression which reported a few days
  ago:

    https://bugzilla.kernel.org/show_bug.cgi?id=47301

  It's a bit of head scratcher but there is a semi-reliable reproduce
