The "set_ios" function is called with a clock of 0 when the clock is
turning off. There's no reason to go through all the extra Rockchip
logic (whose goal is to make sure DIV is 0 or 1) in that case. The
Rockchip logic happened to work because the CCF will pick the lowest
possible rate when you ask it for a clock of 0, but it's silly to go
through all the remuxing and adjusting for no reason.

We've already got a reset of DMA after it's done. Add one before we
start DMA too. This fixes a data corruption on Rockchip SoCs which
will get bad data when doing a DMA transfer after doing a PIO transfer.
We tested this on an Exynos 5800 with HS200 and didn't notice any
difference in sequential read throughput.

While starting the bkops the previously prepared request should be canceled
and restarted after the bkops. As the prepared resource might already
setup the dma channels and ready to be started. Now with the arrival of bkops
request this prepared request can be serviced ONLY after the bkops. So
holding on to the prepared request in the host driver is confusing at
this point in time, so it makes sense to cleanup such dangling requests and
reissue this request once bkops is done.
Canceling the prepared request would give opportunity to the host drivers
to perform cleanup on the prepared request.
Without this patch host drivers like mmci gets confused when a blocking
request like send_ext_csd(CMD8) is issued while there is already a prepared
request. With the help of this patch, the driver can better manage such
blocking requests and cleanup the prepared requests which are not started yet.
Without this patch I hit below crash on Qualcomm APQ8064 based IFC6410 board
with mmci host driver.

Add the case of SET_BLOCK_COUNT command error to the error conditions
check for making a controller reset at request handling finish.
Otherwise, if the SET_BLOCK_COUNT command failed, e.g. with a timeout,
the controller state was not reset, and the next command failed too.
In the case of data error the controller reset is already done in
finish_data() function before sending stop command (if present),
so the finish tasklet should make a reset after data error only
if no stop command existed in the request.

The Parallella board comes with a U-Boot bootloader that loads one of
two predefined FPGA bitstreams before booting the kernel. Both define an
AXI interface to the on-board Epiphany processor.
Enable clocks FCLK0..FCLK3 for the Programmable Logic by default.
Otherwise accessing, e.g., the ESYSRESET register freezes the board,
as seen with the Epiphany SDK tools e-reset and e-hw-rev, using /dev/mem.

Merge tag 'xfs-for-linus-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs fixes from Dave Chinner:
"This update fixes a warning in the new pagecache_isize_extended() and
updates some related comments, another fix for zero-range
misbehaviour, and an unforntuately large set of fixes for regressions
in the bulkstat code.
The bulkstat fixes are large but necessary. I wouldn't normally push
such a rework for a -rcX update, but right now xfsdump can silently
create incomplete dumps on 3.17 and it's possible that even xfsrestore
won't notice that the dumps were incomplete. Hence we need to get
this update into 3.17-stable kernels ASAP.
In more detail, the refactoring work I committed in 3.17 has exposed a
major hole in our QA coverage. With both xfsdump (the major user of
bulkstat) and xfsrestore silently ignoring missing files in the
dump/restore process, incomplete dumps were going unnoticed if they
were being triggered. Many of the dump/restore filesets were so small
that they didn't evenhave a chance of triggering the loop iteration
bugs we introduced in 3.17, so we didn't exercise the code
sufficiently, either.
We have already taken steps to improve QA coverage in xfstests to
avoid this happening again, and I've done a lot of manual verification
of dump/restore on very large data sets (tens of millions of inodes)
of the past week to verify this patch set results in bulkstat behaving
the same way as it does on 3.16.
Unfortunately, the fixes are not exactly simple - in tracking down the
problem historic API warts were discovered (e.g xfsdump has been
working around a 20 year old bug in the bulkstat API for the past 10
years) and so that complicated the process of diagnosing and fixing
the problems. i.e. we had to fix bugs in the code as well as
discover and re-introduce the userspace visible API bugs that we
unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly.
Summary:
- incorrect warnings about i_mutex locking in pagecache_isize_extended()
and updates comments to match expected locking
- another zero-range bug fix for stray file size updates
- a bunch of fixes for regression in the bulkstat code introduced in
3.17"
