And restructure the IRQ handling a little. We can use pipestat for most
things, and make sure we don't affect pipe events when enabling and
disabling vblank interupts.
We can leave vblank interrupts masked but enabled so we're not dependent
on the first client to toggle the disable timer. We can also mask all
render based interrupts, since the ring code will handle unmasking them
for us.

The PTE format is similar to SNB, but we don't support an MLC and don't
need chipset flushing.
Note: I have my questions whether this is right, given that MLC died
for snb & ivb, that ivb has grown a L3$ cache instead (which vlv seems
to have, too) and that the LLC bit here isn't actually LLC, but just
means 'snoop cpu caches'.
But I plan to burn this all with the heat of a thousands suns in my

On filesytems with a block size smaller than PAGE_SIZE we currently have
a problem with unwritten extents. If a we have multi-block page for
which an unwritten extent has been allocated, and only some of the
buffers have been written to, and they are not contiguous, we can expose
stale data from disk in the blocks between the writes after extent
conversion.
Example of a page with unwritten and real data.
buffer content
0 empty b_state = 0
1 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
2 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
3 empty b_state = 0
4 empty b_state = 0
5 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
6 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
7 empty b_state = 0
Buffers 1, 2, 5, and 6 have been written to, leaving 0, 3, 4, and 7
empty. Currently buffers 1, 2, 5, and 6 are added to a single ioend,
and when IO has completed, extent conversion creates a real extent from
block 1 through block 6, leaving 0 and 7 unwritten. However buffers 3
and 4 were not written to disk, so stale data is exposed from those
blocks on a subsequent read.
Fix this by setting iomap_valid = 0 when we find a buffer that is not
Uptodate. This ensures that buffers 5 and 6 are not added to the same
ioend as buffers 1 and 2. Later these blocks will be converted into two
separate real extents, leaving the blocks in between unwritten.

Commit e813a55eb9 ("OMAP: board-files:
remove custom PD GPIO handling for DVI output") moved TFP410 chip's
powerdown-gpio handling from the board files to the tfp410 driver. One
gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in
the Beagle board file. This causes the tfp410 driver to fail to request
the gpio on Beagle, causing the driver to fail and thus the DVI output
doesn't work.
This patch removes several boot errors from board-omap3beagle.c:
- gpio_request: gpio--22 (DVI reset) status -22
- Unable to get DVI reset GPIO
There is a combination of leftover code and revision confusion.
Additionally, xM support is currently a hack.
For original Beagleboard this removes the double initialization of GPIO
170, properly configures it as an output, and wraps the initialization
in an if block so that xM does not attempt to request it.
For Beagleboard xM it removes reference to GPIO 129 which was part
of rev A1 and A2 designs, but never functioned. It then properly assigns
beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the
hack of initializing it high. Additionally, it uses
gpio_set_value_cansleep since this GPIO is connected through i2c.
Unfortunately, there is no way to tell the difference between xM A2 and
A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL
GPIO used on A3 and beyond is not used on rev A1 and A2, there are no
problems created by this fix.
Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4.

This breaks refcounting on the ceph_osd structs that contain the

The purpose of the ->get and ->put methods in a ceph connection are

This is just the minimal patch to disable all this code so that we can
do decent amounts of QA before we rip it all out.
The complicating thing is that we need to flush the gpu caches after
the batchbuffer is emitted. Which is past the point of no return where
execbuffer can't fail any more (otherwise we risk submitting the same
batch multiple times).
Hence we need to add a flag to track whether any caches associated
with that ring are dirty. And emit the flush in add_request if that's
the case.
Note that this has a quite a few behaviour changes:
- Caches get flushed/invalidated unconditionally.
- Invalidation now happens after potential inter-ring sync.
I've bantered around a bit with Chris on irc whether this fixes
anything, and it might or might not. The only thing clear is that with
these changes it's much easier to reason about correctness.
Also rip out a lone get_next_request_seqno in the execbuffer
retire_commands function. I've dug around and I couldn't figure out
why that is still there, with the outstanding lazy request stuff it
shouldn't be necessary.
v2: Chris Wilson complained that I also invalidate the read caches
when flushing after a batchbuffer. Now optimized.
v3: Added some comments to explain the new flushing behaviour.

One small bug fix, plus a rename of all the ST Ericsson regulators in
the device tree since all the device trees had been written with
different names and some infelicities in the test proceedures meant that
the device tree code had apparently never actually been run against the
upstream device tree.

The call to try_module_get() dereferences ld_type outside the
spin locks, which means that it may be pointing to garbage if
a module unload was in progress.

At the moment we call kvmppc_pin_guest_page() in kvmppc_update_vpa()
with two spinlocks held: the vcore lock and the vcpu->vpa_update_lock.
This is not good, since kvmppc_pin_guest_page() calls down_read() and
get_user_pages_fast(), both of which can sleep. This bug was introduced
in 2e25aa5f ("KVM: PPC: Book3S HV: Make virtual processor area
registration more robust").
This arranges to drop those spinlocks before calling
kvmppc_pin_guest_page() and re-take them afterwards. Dropping the
vcore lock in kvmppc_run_core() means we have to set the vcore_state
field to VCORE_RUNNING before we drop the lock, so that other vcpus
won't try to run this vcore.

This solves a section mismatch warning. I hadn't noticed this before,
because my compiler was inlining tegra_cpu_reset_handler_enable() inside
tegra_cpu_reset_handler_init(), which is already __init, but I switched
compilers and it stopped doing that.

Add missing platform_set_drvdata() in gpio_extcon_probe(), otherwise calling
platform_get_drvdata in gpio_extcon_remove() returns NULL.
Also add missing free_irq call in gpio_extcon_remove().

Currently, the index of "Dock-desk" and "Dock-card" are the same.
Thus the latter one overrides the first one.
Then we have problem when calling extcon_find_cable_index() because
edev->supported_cable[7] only matches "Dock-card".

When we fixed the race between atomic_dec and css_refcnt, we missed
the fact that css_refcnt internally subtracts CSS_DEACT_BIAS to get
the actual reference count. This can potentially cause a refcount leak
if __css_put races with cgroup_clear_css_refs.
