RTC: Fix minor compile warning
RTC: Convert rtc drivers to use the alarm_irq_enable method
RTC: Fix rtc driver ioctl specific shortcutting
Currently when two or more buffers are queued by the camera driver
and so the double buffering is enabled in the idmac, we lose one
frame comming from CSI since the reporting of arrival of the first
frame is deferred by the DMAIC_7_EOF interrupt handler and reporting
of the arrival of the last frame is not done at all. So when requesting
N frames from the image sensor we actually receive N - 1 frames in
user space.
The reason for this behaviour is that the DMAIC_7_EOF interrupt
handler misleadingly assumes that the CUR_BUF flag is pointing to the
buffer used by the IDMAC. Actually it is not the case since the
CUR_BUF flag will be flipped by the FSU when the FSU is sending the
<TASK>_NEW_FRM_RDY signal when new frame data is delivered by the CSI.
When sending this singal, FSU updates the DMA_CUR_BUF and the
DMA_BUFx_RDY flags: the DMA_CUR_BUF is flipped, the DMA_BUFx_RDY
is cleared, indicating that the frame data is beeing written by
the IDMAC to the pointed buffer. DMA_BUFx_RDY is supposed to be
set to the ready state again by the MCU, when it has handled the
received data. DMAIC_7_CUR_BUF flag won't be flipped here by the
IPU, so waiting for this event in the EOF interrupt handler is wrong.
Actually there is no spurious interrupt as described in the comments,
this is the valid DMAIC_7_EOF interrupt indicating reception of the
frame from CSI.
The patch removes code that waits for flipping of the DMAIC_7_CUR_BUF
flag in the DMAIC_7_EOF interrupt handler. As the comment in the
current code denotes, this waiting doesn't help anyway. As a result
of this removal the reporting of the first arrived frame is not
deferred to the time of arrival of the next frame and the drivers
software flag 'ichan->active_buffer' is in sync with DMAIC_7_CUR_BUF
flag, so the reception of all requested frames works.
This has been verified on the hardware which is triggering the
image sensor by the programmable state machine, allowing to
obtain exact number of frames. On this hardware we do not tolerate
losing frames.
This patch also removes resetting the DMA_BUFx_RDY flags of
all channels in ipu_disable_channel() since transfers on other
DMA channels might be triggered by other running tasks and the
buffers should always be ready for data sending or reception.

The colorbuffer, zbuffer, and texture states are checked only once when
they get changed. This improves performance in the apps which emit
lots of draw packets and few state changes.
This drops performance in glxgears by a 1% or so, but glxgears is not
a benchmark we care about.
The time spent in the kernel when running Torcs dropped from 33% to 23%
and the frame rate is higher, which is a good thing.
r600 might need something like this as well.

drivers/gpu/drm/radeon/mkregtable.c:parser_auth() almost always remembers
to fclose(file) before returning, but it misses two spots.
This is not really important since the process will exit shortly after and
thus close the file for us, but being explicit prevents static analysis
tools from complaining about leaked memory and missing fclose() calls and
it also seems to be the prefered style of the existing code to explicitly
close the file.
So, here's a patch to add the two missing fclose() calls.

This patch reverts one hunk of 677bd810ee
"ACPI video: remove output switching control", namely the removal of
probing for _DOS/_DOD when searching for video devices.
This is needed on some Fujitsu Laptops (at least S7110, P8010) for the
ACPI backlight interface to work, as an these machines, neither ROM nor
posting methods are available, and after removal of output switching,
none of the caps triggers, which prevents the backlight search from
being entered.
Tested on a Fujitsu Lifebook S7110 and Fujitsu Lifebook P8010.

Commit 9630bdd (ACPI: Use GPE reference counting to support shared
GPEs) introduced a suspend regression where boxes resume immediately
after being suspended due to the lid or sleep button wakeup status
not being cleared properly. This happens if the GPEs corresponding
to those devices are not enabled all the time, which apparently is
expected by some BIOSes.
To fix this problem, enable button and lid GPEs unconditionally
during initialization and keep them enabled all the time, regardless
of whether or not the ACPI button driver is used.

This code makes two calls to clk_get, then test both return values and
fails if either failed.
The problem is that in the first inner if, where the first call to
clk_get has failed, it don't know if the second call has failed as well.
So it don't know whether clk_get should be called on the result of the
second call. Of course, it would be possible to test that value again.
A simpler solution is just to test the result of calling clk_get
directly after each call.

Instrumenting the nbd module's ioctl handler with some extra logging
clearly shows the NBD_DO_IT ioctl being invoked which is a long-lived
ioctl in the sense that it doesn't return until another ioctl asks the
driver to disconnect. However, that other ioctl blocks, waiting for the
module-level mutex that replaced the BKL, and then we're stuck.
This patch removes the module-level mutex altogether. It's clearly
wrong, and as far as I can see, it's entirely unnecessary, since the nbd
driver maintains per-device mutexes, and I don't see anything that would
require a module-level (or kernel-level, for that matter) mutex.

[PATCH V2 2/3] drivers/staging: zcache: host services and PAM services
Zcache provides host services (memory allocation) for tmem,
a "shim" to interface cleancache and frontswap to tmem, and
two different page-addressable memory implemenations using
lzo1x compression. The first, "compression buddies" ("zbud")
compresses pairs of pages and supplies a shrinker interface
that allows entire pages to be reclaimed. The second is
a shim to xvMalloc which is more space-efficient but
less receptive to page reclamation. The first is used
for ephemeral pools and the second for persistent pools.
All ephemeral pools share the same memory, that is, even
pages from different pools can share the same page.

[PATCH V2 1/3] drivers/staging: zcache: in-kernel tmem code
Transcendent memory ("tmem") is a clean API/ABI that provides
for an efficient address translation and a set of highly
concurrent access methods to copy data between a page-oriented
data source (e.g. cleancache or frontswap) and a page-addressable
memory ("PAM") data store. Of critical importance, the PAM data
store is of unknown (and possibly varying) size so any individual
access may succeed or fail as defined by the API/ABI.
Tmem exports a basic set of access methods (e.g. put, get,
flush, flush object, new pool, and destroy pool) which are
normally called from a "host" (e.g. zcache).
To be functional, two sets of "ops" must be registered by the
host, one to provide "host services" (memory allocation) and
one to provide page-addressable memory ("PAM") hooks.
Tmem supports one or more "clients", each which can provide
a set of "pools" to partition pages. Each pool contains
a set of "objects"; each object holds pointers to some number
of PAM page descriptors ("pampd"), indexed by an "index" number.
This triple <pool id, object id, index> is sometimes referred
to as a "handle". Tmem's primary function is to essentially
provide address translation of handles into pampds and move
data appropriately.
As an example, for cleancache, a pool maps to a filesystem,
an object maps to a file, and the index is the page offset
into the file. And in this patch, zcache is the host and
each PAM descriptor points to a compressed page of data.
Tmem supports two kinds of pages: "ephemeral" and "persistent".
Ephemeral pages may be asynchronously reclaimed "bottoms up"
so the data structures and concurrency model must allow for
this. For example, each pampd must retain sufficient information
to invalidate tmem's handle-to-pampd translation.
its containing object so that, on reclaim, all tmem data
structures can be made consistent.

The functions acpi_os_read_memory() and acpi_os_write_memory() do
two wrong things. First, they shouldn't call rcu_read_unlock()
before the looked up address is actually used for I/O, because in
that case the iomap it belongs to may be removed before the I/O
is done. Second, if they have to create a new mapping, they should
check the returned virtual address and tell the caller that the
operation failed if it is NULL (in fact, I think they even should not
attempt to map an address that's not present in one of the existing
ACPI iomaps, because that may cause problems to happen when they are
called from nonpreemptible context and their callers ought to know
what they are doing and map the requisite memory regions beforehand).
Make these functions call rcu_read_unlock() when the I/O is complete
(or if it's necessary to map the given address "on the fly") and
return an error code if the requested physical address is not present
in the existing ACPI iomaps and cannot be mapped.

Currently the driver increments the tx_timeout counter (an error counter)
when simply resetting the part with outstanding transmit work pending.
This is an unnecessary count of an error, when all we should be doing is
just resetting the part and discarding the transmits. With this change the
only increment of tx_timeout is when the stack calls the watchdog reset
function due to a true Tx timeout.

Following symptoms were observed:
1. After raid0->raid10 takeover operation we have array with 2
missing disks.
When we add disk for rebuild, recovery process starts as expected
but it does not finish- it stops at about 90%, md126_resync process
hangs in "D" state.
2. Similar behavior is when we have mounted raid0 array and we
execute takeover to raid10. After this when we try to unmount array-
it causes process umount hangs in "D"
In scenarios above processes hang at the same function- wait_barrier
in raid10.c.
Process waits in macro "wait_event_lock_irq" until the
"!conf->barrier" condition will be true.
In scenarios above it never happens.
Reason was that at the end of level_store, after calling pers->run,
we call mddev_resume. This calls pers->quiesce(mddev, 0) with
RAID10, that calls lower_barrier.
However raise_barrier hadn't been called on that 'conf' yet,
so conf->barrier becomes negative, which is bad.
This patch introduces setting conf->barrier=1 after takeover
operation. It prevents to become barrier negative after call
lower_barrier().

md_make_request was calling bio_sectors() for part_stat_add
after it was calling the make_request function. This is
bad because the make_request function can free the bio and
because the bi_size field can change around.
The fix here was suggested by Jens Axboe. It saves the
sector count before the make_request call. I hit this
with CONFIG_DEBUG_PAGEALLOC turned on while trying to break

For some strange reason, the DSP base image node/object properties
description string stores hexadecimal numbers with a 'h' or 'H' suffix
instead of a '0x' prefix. This causes parsing issue because the
dspbridge atoi() implementation relies on strict_strtoul(), which will
return an error because of the trailing 'h' character.
As the atoi() return value is never checked for an error anyway, replace
strict_strtoul() with simple_strtoul() to ignore the suffix.
This fix gets rid of the following assertion failed messages that were
printed when running the dsp-dummy test application.

This patch eliminates duplicate code. The remove_block_head function
is a special case of remove_block which can be contained in remove_block
without confusion.
The portion of code in remove_block_head which was noted as "DEBUG ONLY"
is now mandatory. Doing this provides consistent management of the double
linked list of blocks under a freelist and makes this consolidation
of delete block code safe. The first and last blocks will have NULL
pointers in their previous and next page pointers respectively.
Additionally, any time a block is removed from a free list the next and
previous pointers will be set to NULL to avoid misuse outside xvmalloc.

Currently zram will do nothing to the page in the bvec when that page
has not been previously written. This allows random data to leak to
user space. That can be seen by doing the following:
## Load the module and create a 256Mb zram device called /dev/zram0
# modprobe zram
# echo $((256*1024*1024)) > /sys/class/block/zram0/disksize
## Initialize the device by writing zero to the first block
# dd if=/dev/zero of=/dev/zram0 bs=512 count=1
## Read ~256Mb of memory into a file and hope for something interesting
# dd if=/dev/zram0 of=file
This patch will treat an unwritten page as a zero-filled page. If a
page is read before a write has occurred the data returned is all 0's.

This change is in a conditional block which is entered only when there is
an existing data block on the freelist where the insert has taken place.
The new block is pushed onto the freelist stack and this conditional block
is updating links in the prior stack head to point to the new stack head.
After this conditional block the first-/second-level indices are updated
to indicate that there is a free block at this location.
This patch adds an immediate return from the conditional block to avoid
setting bits again to indicate a free block on this freelist. The bits
would already be set because there was an existing free block on this
freelist.

xvmalloc will not currently function with 64K pages. Newly allocated
pages will be inserted at an offset beyond the end of the first-level
index. This tuning is needed to properly size the allocator for 64K
pages.
The default 3 byte shift results in a second level list size which can not
be indexed using the 64 bits of the flbitmap in the xv_pool structure.
The shift must increase to 4 bytes between second level list entries to
fit the size of the first level bitmap.
Here are a few statistics for structure sizes on 32- and 64-bit CPUs
with 4KB and 64KB page sizes.
bits_per_long 32 64 64
page_size 4,096 4,096 65,535
xv_align 4 8 8
fl_delta 3 3 4
num_free_lists 508 508 4,094

per object overhead 32 64 64
zram struct 0.5GB disk 512KB 1024KB 64KB

sizing for 64K pages and adds a safe tuning for any other page sizes.
