Because the counters use a custom batch size, the comparison
functions need to be aware of that batch size otherwise the
comparison does not work correctly. This leads to ASSERT failures
on generic/027 like this:

This is a regression introduced by commit 501ab32 ("xfs: use generic
percpu counters for inode counter").
This patch fixes the same problem for both the inode counter and the
free block counter in the superblocks.

XFS uses non-stanard batch sizes for avoiding frequent global
counter updates on it's allocated inode counters, as they increment
or decrement in batches of 64 inodes. Hence the standard percpu
counter batch of 32 means that the counter is effectively a global
counter. Currently Xfs uses a batch size of 128 so that it doesn't
take the global lock on every single modification.
However, Xfs also needs to compare accurately against zero, which
means we need to use percpu_counter_compare(), and that has a
hard-coded batch size of 32, and hence will spuriously fail to
detect when it is supposed to use precise comparisons and hence
the accounting goes wrong.
Add __percpu_counter_compare() to take a custom batch size so we can
use it sanely in XFS and factor percpu_counter_compare() to use it.

Function percpu_counter_read just return the current counter, which can be
negative. This will cause the checking of "allocated inode
counts <= m_maxicount" false positive. Use percpu_counter_read_positive can
solve this problem, and be consistent with the purpose to introduce percpu
mechanism to xfs.

bdi_unregister() now contains very little functionality.
It contains a "WARN_ON" if bdi->dev is NULL. This warning is of no
real consequence as bdi->dev isn't needed by anything else in the function,
and it triggers if
blk_cleanup_queue() -> bdi_destroy()
is called before bdi_unregister, which happens since
Commit: 6cd18e711dd8 ("block: destroy bdi before blockdev is unregistered.")
So this isn't wanted.
It also calls bdi_set_min_ratio(). This needs to be called after
writes through the bdi have all been flushed, and before the bdi is destroyed.
Calling it early is better than calling it late as it frees up a global
resource.
Calling it immediately after bdi_wb_shutdown() in bdi_destroy()
perfectly fits these requirements.
So bdi_unregister() can be discarded with the important content moved to
bdi_destroy(), as can the
writeback_bdi_unregister
event which is already not used.

The power management related assembly on omaps needs to interact with
ARM mode bootrom code, so we need to keep most of the related assembly
in ARM mode.
Turns out this error is because of missing ENDPROC for assembly code
as suggested by Stephen Boyd <sboyd@codeaurora.org>. Let's fix the
problem by adding ENDPROC in two places to sleep34xx.S.
Let's also remove the now duplicate custom code for mode switching.
This has been unnecessary since commit 6ebbf2ce437b ("ARM: convert
all "mov.* pc, reg" to "bx reg" for ARMv6+").
And let's also remove the comments about local variables, they are
now just confusing after the ENDPROC.
The reason why ENDPROC makes a difference is it sets .type and then
the compiler knows what to do with the thumb bit as explained at:

The cmd_in_flight tracking was introduced to workaround faulty
power management hardware, by having the driver keep the NIC
awake as long as there are commands in flight. However, some of
the code handling this workaround was unconditionally executed,
which resulted with an inconsistent state where the driver assumed
that the NIC was awake although it wasn't.
Fix this by renaming 'cmd_in_flight' to 'cmd_hold_nic_awake' and
handling the NIC requested awake state only for hardwares for
which the workaround is needed.

This commit introduces a variant of the mv_mbus_dram_info() function
called mv_mbus_dram_info_nooverlap(). Both functions are used by
Marvell drivers supporting devices doing DMA, and provide them a
description the DRAM ranges that they need to configure their DRAM
windows.
The ranges provided by the mv_mbus_dram_info() function may overlap
with the I/O windows if there is a lot (>= 4 GB) of RAM
installed. This is not a problem for most of the DMA masters, except
for the upcoming new CESA crypto driver because it does DMA to the
SRAM, which is mapped through an I/O window. For this unit, we need to
have DRAM ranges that do not overlap with the I/O windows.
A first implementation done in commit 1737cac69369 ("bus: mvebu-mbus:
make sure SDRAM CS for DMA don't overlap the MBus bridge window"),
changed the information returned by mv_mbus_dram_info() to match this
requirement. However, it broke the requirement of the other DMA
masters than the DRAM ranges should have power of two sizes.
To solve this situation, this commit introduces a new
mv_mbus_dram_info_nooverlap() function, which returns the same
information as mv_mbus_dram_info(), but guaranteed to not overlap with
the I/O windows.
In the end, it gives us two variants of the mv_mbus_dram_info*()
functions:
- The normal one, mv_mbus_dram_info(), which has been around for many
years. This function returns the raw DRAM ranges, which are
guaranteed to use power of two sizes, but will overlap with I/O
windows. This function will therefore be used by all DMA masters
(SATA, XOR, Ethernet, etc.) except the CESA crypto driver.
- The new 'nooverlap' variant, mv_mbus_dram_info_nooverlap(). This
function returns DRAM ranges after they have been "tweaked" to make
sure they don't overlap with I/O windows. By doing this tweaking,
we remove the power of two size guarantee. This variant will be
used by the new CESA crypto driver.

bridge window"
This reverts commit 1737cac69369 ("bus: mvebu-mbus: make sure SDRAM CS
for DMA don't overlap the MBus bridge window"), because it breaks DMA
on platforms having more than 2 GB of RAM.
This commit changed the information reported to DMA masters device
drivers through the mv_mbus_dram_info() function so that the returned
DRAM ranges do not overlap with I/O windows.
This was necessary as a preparation to support the new CESA Crypto
Engine driver, which will use DMA for cryptographic operations. But
since it does DMA with the SRAM which is mapped as an I/O window,
having DRAM ranges overlapping with I/O windows was problematic.
To solve this, the above mentioned commit changed the mvebu-mbus to
adjust the DRAM ranges so that they don't overlap with the I/O
windows. However, by doing this, we re-adjust the DRAM ranges in a way
that makes them have a size that is no longer a power of two. While
this is perfectly fine for the Crypto Engine, which supports DRAM
ranges with a granularity of 64 KB, it breaks basically all other DMA
masters, which expect power of two sizes for the DRAM ranges.
Due to this, if the installed system memory is 4 GB, in two
chip-selects of 2 GB, the second DRAM range will be reduced from 2 GB
to a little bit less than 2 GB to not overlap with the I/O windows, in
a way that results in a DRAM range that doesn't have a power of two
size. This means that whenever you do a DMA transfer with an address
located in the [ 2 GB ; 4 GB ] area, it will freeze the system. Any
serious DMA activity like simply running:
for i in $(seq 1 64) ; do dd if=/dev/urandom of=file$i bs=1M count=16 ; done
in an ext3 partition mounted over a SATA drive will freeze the system.
Since the new CESA crypto driver that uses DMA has not been merged
yet, the easiest fix is to simply revert this commit. A follow-up
commit will introduce a different solution for the CESA crypto driver.

A recent change removed the need for locking around writing
to "sync_action" (and various other places), but introduced a
subtle race.
When e.g. setting 'reshape' on a 'frozen' array, the 'frozen'
flag is cleared before 'reshape' is set, so the md thread can
get in and start trying recovery - which isn't wanted.
So instead of clearing MD_RECOVERY_FROZEN for any command
except 'frozen', only clear it when each specific command
is parsed. This allows the handling of 'reshape' to clear
the bit while a lock is held.
Also remove some places where we set MD_RECOVERY_NEEDED,
as it is always set on non-error exit of the function.

The patch removes the use of timekeeping_valid_for_hres which is now
marked as internal for the time keeping subsystem. The jitterentropy
does not really require this verification as a coarse timer (when
random_get_entropy is absent) is discovered by the initialization test
of jent_entropy_init, which would cause the jitter rng to not load in
that case.

This patch makes use of the new AEAD interface which uses a single
SG list instead of separate lists for the AD and plain text.
Note that the user-space interface now requires both input and
output to be of the same length, and both must include space for
the AD as well as the authentication tag.

This patch defines the behaviour of AD in the new interface more
clearly. In particular, it specifies that if the user must copy
the AD to the destination manually when src != dst if they wish
to guarantee that the destination buffer contains a copy of the
AD.
The reason for this is that otherwise every AEAD implementation
would have to perform such a copy when src != dst. In reality
most users do in-place processing where src == dst so this is
not an issue.
This patch also kills some remaining references to cryptoff.
