As amd driver doesn't bind to PCI device, we'd better manage reource

- add IRQF_SHARED to request_irq flags to support parts such as
the p1023 that has one IRQ line per couple of rings.
- resetting a job ring triggers an interrupt, so move request_irq
prior to jr_reset to avoid 'got IRQ but nobody cared' messages.
- disable IRQs in h/w to avoid contention between reset and
interrupt status
- delete invalid comment - if there were incomplete jobs,
module would be in use, preventing an unload.

This patch fixes 2 hmac inter-dependent bugs.
1. "omap-sham: hash-in-progress is stored in hw format" commit introduced
optimization where temporary hash had been stored in OMAP specific format
(big endian).
For SHA1 it is different to real hash format, which is little endian.
Final HMAC value was calculated using incorrect hash.
Because CONFIG_CRYPTO_MANAGER_TESTS was disabled this error remained
unnoticed. After enabling this option, bug has been found.
2. HMAC was calculated using temporrary hash value.
For a single-request updates, temporary hash was the final one and
HMAC result was correct. But in fact only the final hash had to be used.
All crypto tests for HMAC produces only single request and
could not catch the problem. This problem is fixed here.

The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status
FIFO. The command FIFO takes the requests that are to be performed and
the status FIFO reports the results. It is possible to get into the
situation where there are more free spaces in the command FIFO than the
status FIFO if we don't empty the status FIFO quickly enough resulting
in a possible overflow of the status FIFO. This can result in incorrect
status being reported in the status FIFO.
Make sure that when we are submitting requests the number of requests
that have been dispatched but not yet popped from the status FIFO does
not exceed the size of a single FIFO.

Add new SHA-1/256 module that never needs any fallback and just calls the
PadLock hardware instruction supported from VIA Nano processors to implement
the "update" and "final" function.
They are respectively named "sha1_alg_nano" and "sha256_alg_nano", and will
be used on any VIA Nano processor or the later ones. On VIA C7 CPU, the
"sha1_alg" and "sha256_alg" modules will still be used as before.

- all the integration parameters have been captured by the binding.
- the block name really uniquely identifies this hardware.
Some advocate putting SoC names everywhere in case software needs
to work around some chip-specific bug, but more precise SoC
information already exists in SVR, and board information already
exists in the top-level device tree node.
Note that sometimes the SoC name is a worse identifier than the
block version, as the block version can change between revisions
of the same SoC.
As a matter of historical reference, neither SEC versions 2.x
nor 3.x (driven by talitos) ever needed CHIP references.

ARRAY_SIZE() was intended here instead of sizeof(). sizeof() is four
times larger than ARRAY_SIZE(). outstr is normally 256 chars so
printing garbage to it could overfill the buffer and corrupt memory.

The SEC4 supercedes the SEC2.x/3.x as Freescale's
Integrated Security Engine. Its programming model is
incompatible with all prior versions of the SEC (talitos).
The SEC4 is also known as the Cryptographic Accelerator
and Assurance Module (CAAM); this driver is named caam.
This initial submission does not include support for Data Path
mode operation - AEAD descriptors are submitted via the job
ring interface, while the Queue Interface (QI) is enabled
for use by others. Only AEAD algorithms are implemented
at this time, for use with IPsec.
Many thanks to the Freescale STC team for their contributions
to this driver.

commit c340b1d64000 ("fs/partitions/ldm.c: fix oops caused by corrupted

previously allocated memory is used.

Don't powerdown Compaq Triflex IDE device on suspend
This fixes APM suspend on Compaq Armada 7400.
APM BIOS doesn't suspend if IDE is powered down when suspending.
The Triflex controller is found only on old Compaq boards,

Previously we used Maximum Unmap LBA Count in the Block Limits VPD to
signal the maximum number of sectors we could handle in a single Write
Same command.
Starting with SBC3r26 the Block Limits VPD has an explicit limit on the
number of blocks in a Write Same. This means we can stop abusing a field
related to the Unmap command and let our SAT use the proper value in the
VPD (Maximum Write Same Length).

* New code correctly calculates SMC registers values, adjusts calculated
to admissible ranges, enlarges cycles when required and converts values
into SMC's format.
* Support for TDF cycles (ATA t6z) and IORDY line added.
* Eliminate need in the initial_timing structure.
* Code cleanup.

This is a cosmetic change to prevent libata-sff adding irq
descriptions to dummy ports, since the information, while largely
unused, is erroneous.

The old IDE cmd64x checks the status of the CNTRL register to see if
the ports are enabled before probing them. pata_cmd64x doesn't do
this, which causes a HPMC on parisc when it tries to poke at the
secondary port because apparently the BAR isn't wired up (and a
non-responding piece of memory causes a HPMC).
Fix this by porting the CNTRL register port detection logic from IDE
cmd64x. In addition, following converns from Alan Cox, add a check to
see if a mobility electronics bridge is the immediate parent and forgo
the check if it is (prevents problems on hotplug controllers).

When building with:
CONFIG_64BIT=y
CONFIG_MIPS32_COMPAT=y
CONFIG_COMPAT=y
CONFIG_MIPS32_O32=y
CONFIG_MIPS32_N32=y
CONFIG_SYSVIPC is not set
(and implicitly: CONFIG_SYSVIPC_COMPAT is not set)
the final link fails with unresolved symbols for:
compat_sys_semctl, compat_sys_msgsnd, compat_sys_msgrcv,
compat_sys_shmctl, compat_sys_msgctl, compat_sys_semtimedop
The fix is to add cond_syscall declarations for all syscalls in
ipc/compat.c

commit a35e2c1b6d905 (macvlan: use rx_handler_data pointer to store
macvlan_port pointer V2) added a bug in macvlan_port_create()
Steps to reproduce the bug:
# ifenslave bond0 eth0 eth1
# ip link add link eth0 up name eth0#1 type macvlan
->error EBUSY
# ip link add link eth0 up name eth0#1 type macvlan
->panic
Fix: Dont set IFF_MACVLAN_PORT in error case.

Commit dabc5c670d3f86d15ee4f42ab38ec5bd2682487d, entitled
"tg3: Move TSO_CAPABLE assignment", moved some TSO flagging code around.
In the process it failed to add braces around an exceptional 5906
condition. This patch fixes the problem.

Mahesh Bandewar noticed that the features cleanup in commit
0da0606f493c5cdab74bdcc96b12f4305ad94085, entitled
"tg3: Consolidate all netdev feature assignments", mistakenly sets
NETIF_F_LOOPBACK by default. This patch corrects the error.

When one macvlan device is dismantled, we can avoid one
synchronize_rcu() call done after deletion from hash list, since caller
will perform a synchronize_net() call after its ndo_stop() call.
Add a new netdev->dismantle field to signal this dismantle intent.
Reduces RTNL hold time.

IP_ROUTE_CLASSID depends on INET and NET_CLS_ROUTE4 selects
IP_ROUTE_CLASSID, but when INET is not enabled, this kconfig warning
is produced, so fix it by making NET_CLS_ROUTE4 depend on INET.
warning: (NET_CLS_ROUTE4) selects IP_ROUTE_CLASSID which has unmet direct dependencies (NET && INET)

The variable 'ret' is set but unused, and this pointed out that
errors from irlmp_connect_response() are not propagated to the
caller.
Note that this is currently academic since irlmp_connect_response()
always returns 0. :-)
