ALSA: pcm: fix delta calculation at boundary wraparound
In the cleanup of the hw_ptr update functions in 2.6.33, the calculation
of the delta value was changed to use the modulo operator to protect
against a negative difference due to the pointer wrapping around at the
boundary.
However, the ptr variables are unsigned, so a negative difference would
result in the two complement's value which has no relation to the actual
difference relative to the boundary; the result is typically some value
near LONG_MAX-boundary. Furthermore, even if the modulo operation would
be done with signed types, the result of a negative dividend could be
negative.
The invalid delta value is then caught by the following checks, but this
means that the pointer update is ignored.
To fix this, use a range check as in the other pointer calculations.

ALSA: pcm: fix the fix of the runtime->boundary calculation
Commit
7910b4a1db63fefc3d291853d33c34c5b6352e8e in 2.6.34 changed the
runtime->boundary calculation to make this value a multiple of both the
buffer_size and the period_size, because the latter is assumed by the
runtime->hw_ptr_interrupt calculation.
However, due to the lack of a ioctl that could read the software
parameters before they are set, the kernel requires that alsa-lib
calculates the boundary value, too. The changed algorithm leads to
a different boundary value used by alsa-lib, which makes, e.g., mplayer
fail to play a 44.1 kHz file because the silence_size parameter is now
invalid; bug report:
<https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5015>.
This patch reverts the change to the boundary calculation, and instead
fixes the hw_ptr_interrupt calculation to be period-aligned regardless
of the boundary value.

i2c-omap: add mpu wake up latency constraint in i2c
While waiting for completion of the i2c transfer, the
MPU could hit OFF mode and cause several msecs of
delay that made i2c transfers fail more often. The
extra delays and subsequent re-trys cause i2c clocks
to be active more often. This has also an negative
effect on power consumption.
Created a mechanism for passing and using the
constraint setting function in driver code. The used
mpu wake up latency constraints are now set individually
per bus, and they are calculated based on clock rate
and fifo size.
Thanks to Jarkko Nikula, Moiz Sonasath, Paul Walmsley,
and Nishanth Menon for tuning out the details of
this patch.
Updates by Kevin as requested by Tony:
- Remove omap_set_i2c_constraint_func() in favor of conditionally
adding the flag in omap_i2c_add_bus() in order to keep all the OMAP
conditional checking in a single location.
- Update set_mpu_wkup_lat prototypes to match OMAP PM layer so
OMAP PM function can be used directly in pdata.

i2c-s3c2410: Remove unconditional 1ms delay on each transfer
The S3C I2C controller indicates completion of I2C transfers before
the bus has a stop condition on it. In order to ensure that we do not
attempt to start a new transfer before the bus is idle the driver
currently inserts a 1ms delay. This is vastly larger than is generally
required and has a visible effect on performance under load, such as
when bringing up audio CODECs or reading back status information with
non-bulk I2C reads.
Replace the sleep with a spin on the IIC status register for up to 1ms.
This will busy wait but testing on my SMDK6410 system indicates that
the overwhelming majority of transactions complete on the first spin,
with maximum latencies of less than 10 spins so the absolute overhead
of busy waiting should be at worst comprable to msleep(), and the
overall system performance is dramatically improved.
The main risk is poor interaction with multimaster systems where
we may miss the bus going idle before the next transaction. Defend
against this by falling back to the original 1ms delay after 20 spins.
The overall effect in my testing is an approximately 20% improvement
in kernel startup time.

cpumask: fix compat getaffinity
Commit
a45185d2d "cpumask: convert kernel/compat.c" broke libnuma, which
abuses sched_getaffinity to find out NR_CPUS in order to parse
/sys/devices/system/node/node*/cpumap.
On NUMA systems with less than 32 possibly CPUs, the current
compat_sys_sched_getaffinity now returns '4' instead of the actual
NR_CPUS/8, which makes libnuma bail out when parsing the cpumap.
The libnuma call sched_getaffinity(0, bitmap, 4096) at first. It mean
the libnuma expect the return value of sched_getaffinity() is either len
argument or NR_CPUS. But it doesn't expect to return nr_cpu_ids.
Strictly speaking, userland requirement are
1) Glibc assume the return value mean the lengh of initialized
of mask argument. E.g. if sched_getaffinity(1024) return 128,
glibc make zero fill rest 896 byte.
2) Libnuma assume the return value can be used to guess NR_CPUS
in kernel. It assume len-arg<NR_CPUS makes -EINVAL. But
it try len=4096 at first and 4096 is always bigger than
NR_CPUS. Then, if we remove strange min_length normalization,
we never hit -EINVAL case.
sched_getaffinity() already solved this issue. This patch adapts
compat_sys_sched_getaffinity() to match the non-compat case.

libata-sff: clean up BMDMA initialization
When BMDMA initialization failed or BMDMA was not available for
whatever reason, bmdma_addr was left at zero and used as an indication
that BMDMA shouldn't be used. This leads to the following problems.
p1. For BMDMA drivers which don't use traditional BMDMA register,
ata_bmdma_mode_filter() incorrectly inhibits DMA modes. Those
drivers either have to inherit from ata_sff_port_ops or clear
->mode_filter explicitly.
p2. non-BMDMA drivers call into BMDMA PRD table allocation. It
doesn't actually allocate PRD table if bmdma_addr is not
initialized but is still confusing.
p3. For BMDMA drivers which don't use traditional BMDMA register, some
methods might not be invoked as expected (e.g. bmdma_stop from
ata_sff_post_internal_cmd()).
p4. SFF drivers w/ custom DMA interface implement noop BMDMA ops
worrying libata core might call into one of them.
These problems are caused by the muddy line between SFF and BMDMA and
the assumption that all BMDMA controllers initialize bmdma_addr.
This patch fixes p1 and p2 by removing the bmdma_addr assumption and
moving prd allocation to BMDMA port start. Later patches will fix the
remaining issues.
This patch improves BMDMA initialization such that
* When BMDMA register initialization fails, falls back to PIO instead
of failing. ata_pci_bmdma_init() never fails now.
* When ata_pci_bmdma_init() falls back to PIO, it clears
ap->mwdma_mask and udma_mask instead of depending on
ata_bmdma_mode_filter(). This makes ata_bmdma_mode_filter()
unnecessary thus resolving p1.
* ata_port_start() which actually is BMDMA specific is moved to
ata_bmdma_port_start(). ata_port_start() and ata_sff_port_start()
are killed.
* ata_sff_port_start32() is moved and renamed to
ata_bmdma_port_start32().
Drivers which no longer call into PRD table allocation are...
pdc_adma, sata_inic162x, sata_qstor, sata_sx4, pata_cmd640 and all
drivers which inherit from ata_sff_port_ops.
pata_icside sets ->port_start to ATA_OP_NULL as it doesn't need PRD
but is a BMDMA controller and doesn't have custom port_start like
other such controllers.
Note that with the previous patch which makes all and only BMDMA
drivers inherit from ata_bmdma_port_ops, this change doesn't break
drivers which need PRD table.

3. In sata_mv, unlike mv5, mv6 is BMDMA. Inherit from bmdma and

4. bf54x and icside are quasi-BMDMA controllers which don't use the

DMA modes if bmdma_addr is not initialized.
For 2 and 3, this patch makes the drivers explicitly specify

D'oh. Okay, here's v2, should fix that buglet too.
This hack was used when the imon driver was using internal key lookup

After reviewing the logic at the function, instead of just adding a patch to
revert the wrong one, the better is to apply a different logic: add a goto
that will always unlock and return the error.
This simplifies the code a little bit, and, instead of just return -EINVAL,
it will return the error condition reported by the called functions.
This patch is folded with another patch from Dan that added one missing
goto.

V4L/DVB: s2255drv: return if vdev not found
The original code didn't handle the case where vdev was not found so I
added a check for that.

V4L/DVB: ov511: cleanup: remove unneeded null check
We dereference "ov" unconditionally throughout the function so there is
no way it can be NULL here. This code has been around for ages so if
it were possible for "ov" to be NULL someone would have complained.

V4L/DVB: dvb/stv6110x: cleanup error handling
The "stv6110x" is NULL so we can just return directly without calling
kfree(). Also I changed the printk() to make checkpatch.pl happy.
