have added bits that are not specific to the WRIOP accelerator.
Move these where they belong (in DPIO) such that other accelerators
can make use of them.
While here, fix the values of FD_CTRL_FSE and FD_CTRL_FAERR, which
were shifted off by one bit.

For more than 16 S/G entries, driver currently corrupts memory
on ARMv8, see below KASAN log.
Note: this does not reproduce on PowerPC due to different (smaller)
cache line size - 64 bytes on PPC vs. 128 bytes on ARMv8.
One such use case is one of the cbc(aes) test vectors - with 8 S/G
entries and src != dst. Driver needs 1 (IV) + 2 x 8 = 17 entries,
which goes over the 16 S/G entries limit:
(CAAM_QI_MEMCACHE_SIZE - offsetof(struct ablkcipher_edesc, sgt)) /
sizeof(struct qm_sg_entry) = 256 / 16 = 16 S/Gs
Fix this by:
-increasing object size in caamqicache pool from 512 to 768; this means
the maximum number of S/G entries grows from (at least) 16 to 32
(again, for ARMv8 case of 128-byte cache line)
-add checks in the driver to fail gracefully (ENOMEM) in case the 32 S/G
entries limit is exceeded

Certain cipher modes like CTS expect the IV (req->info) of
ablkcipher_request (or equivalently req->iv of skcipher_request) to
contain the last ciphertext block when the {en,de}crypt operation is done.
This is currently not the case for the CAAM driver which in turn breaks
e.g. cts(cbc(aes)) when the CAAM driver is enabled.
This patch fixes the CAAM driver to properly set the IV after the
{en,de}crypt operation of ablkcipher finishes.
This issue was revealed by the changes in the SW CTS mode in commit
0605c41cc53ca ("crypto: cts - Convert to skcipher")

This is the 2nd part of fixing the usage of GFP_KERNEL for memory
allocations, taking care off all the places that haven't caused a real
problem / failure.
Again, the issue being fixed is that GFP_KERNEL should be used only when
MAY_SLEEP flag is set, i.e. MAY_BACKLOG flag usage is orthogonal.

Changes in the SW cts (ciphertext stealing) code in
commit 0605c41cc53ca ("crypto: cts - Convert to skcipher")
revealed a problem in the CAAM driver:
when cts(cbc(aes)) is executed and cts runs in SW,
cbc(aes) is offloaded in CAAM; cts encrypts the last block
in atomic context and CAAM incorrectly decides to use GFP_KERNEL
for memory allocation.
Fix this by allowing GFP_KERNEL (sleeping) only when MAY_SLEEP flag is
set, i.e. remove MAY_BACKLOG flag.
We split the fix in two parts - first is sent to -stable, while the
second is not (since there is no known failure case).

caam/qi has been backported to kernel v4.4, however the same is not
true for the Queue & Buffer Manager driver, i.e. the SDK version of it
is used instead of a backport of its upstream version.
Update caam/qi to work with QBMan from NXP SDK.

Update txq0's trans_start in order to prevent the netdev watchdog from
triggering too quickly. Since we set the LLTX flag, the stack won't update
the jiffies for other tx queues. Prevent the watchdog from checking the
other tx queues by adding the NETIF_HW_ACCEL_MQ flag.

The wrong register is checked for the Tx flow control bit,
it should have been maccfg1 not maccfg2.
This went unnoticed for so long probably because the impact is
hardly visible, not to mention the tangled code from adjust_link().
First, link flow control (i.e. handling of Rx/Tx link level pause frames)
is disabled by default (needs to be enabled via 'ethtool -A').
Secondly, maccfg2 always returns 0 for tx_flow_oldval (except for a few
old boards), which results in Tx flow control remaining always on
once activated.

For each subsequent device assigned to the m4u_group after its initial
allocation, we need to take an additional reference. Otherwise, the
caller of iommu_group_get_for_dev() will inadvertently remove the
reference taken by iommu_group_add_device(), and the group will be
freed prematurely if any device is removed.
