raid: improve MD/raid10 handling of correctable read errors.
We've noticed severe lasting performance degradation of our raid
arrays when we have drives that yield large amounts of media errors.
The raid10 module will queue each failed read for retry, and also
will attempt call fix_read_error() to perform the read recovery.
Read recovery is performed while the array is frozen, so repeated
recovery attempts can degrade the performance of the array for
extended periods of time.
With this patch I propose adding a per md device max number of
corrected read attempts. Each rdev will maintain a count of
read correction attempts in the rdev->read_errors field (not
used currently for raid10). When we enter fix_read_error()
we'll check to see when the last read error occurred, and
divide the read error count by 2 for every hour since the
last read error. If at that point our read error count
exceeds the read error threshold, we'll fail the raid device.
In addition in this patch I add sysfs nodes (get/set) for
the per md max_read_errors attribute, the rdev->read_errors
attribute, and added some printk's to indicate when
fix_read_error fails to repair an rdev.
For testing I used debugfs->fail_make_request to inject
IO errors to the rdev while doing IO to the raid array.

md/bitmap: update dirty flag when bitmap bits are explicitly set.
There is a sysfs file which allows bits in the write-intent

When this happens we should really set recovery_cp backwards

md: support barrier requests on all personalities.
Previously barriers were only supported on RAID1. This is because
other levels requires synchronisation across all devices and so needed
a different approach.
Here is that approach.
When a barrier arrives, we send a zero-length barrier to every active
device. When that completes - and if the original request was not
empty - we submit the barrier request itself (with the barrier flag
cleared) and then submit a fresh load of zero length barriers.
The barrier request itself is asynchronous, but any subsequent
request will block until the barrier completes.
The reason for clearing the barrier flag is that a barrier request is
allowed to fail. If we pass a non-empty barrier through a striping
raid level it is conceivable that part of it could succeed and part
could fail. That would be way too hard to deal with.
So if the first run of zero length barriers succeed, we assume all is
sufficiently well that we send the request and ignore errors in the
second run of barriers.
RAID5 needs extra care as write requests may not have been submitted
to the underlying devices yet. So we flush the stripe cache before
proceeding with the barrier.
Note that the second set of zero-length barriers are submitted
immediately after the original request is submitted. Thus when
a personality finds mddev->barrier to be set during make_request,
it should not return from make_request until the corresponding
per-device request(s) have been queued.
That will be done in later patches.

A write intent bitmap can be removed from an array while the
array is active.
When this happens, all IO is suspended and flushed before the
bitmap is removed.
However it is possible that bitmap_daemon_work is still running to
clear old bits from the bitmap. If it is, it can dereference the

before destroying a bitmap.

In general, we should never take the BKL while we're holding a spinlock,

technically sleep - at least not yet), and we'll get nice warnings the
next time this kind of problem happens during BKL removal.

omap: mux: Add new style pin multiplexing data for 34xx
Add new style mux data for 34xx. This should also
work with 3630 easily by adding the processor subset
and ball data.
Note that this data is __initdata, and gets optimized
out except for the GPIO pins if CONFIG_OMAP_MUX
is not set.
Also note that this data uses omap3630 naming for
the SDMMC registers instead of 34xx naming with just
MMC.

omap: mux: Add new style pin multiplexing code for omap3
Initially only for 34xx. This code allows us to:
- Make the code more generic as the omap internal signal
names can stay the same across omap generations for some
devices
- Map mux registers to GPIO registers that is needed for
dynamic muxing of pins during off-idle
- Override bootloader mux values via kernel cmdline using
omap_mux=some.signa1=0x1234,some.signal2=0x1234
- View and set the mux registers via debugfs if
CONFIG_DEBUG_FS is enabled

ARM: OMAP4: PM: Add init api for DPLL nodes
An api at init for all dpll nodes seem to be
needed to reparent the dpll clk node to its
bypass clk in case the dpll is in bypass.
If not done this causes sequencing issues at init
during propogate_rate.
