This patch fixes a false positive uninitialised variable warning
in aead_perform by moving the source processing in front of the

This patch saves the value of the internal hash register at the end of an
'update' operation then restores this value before starting the next
'update'. This way the driver can now properly handle context switches.
WARNING: only hardware versions from sama5d4x and later provide the
needed interface to update the internal hash value. Especially, sama5d3x
cannot implement this feature so context switches are still broken.

The 'done' tasklet handler used to check the 'BUSY' flag to either
finalize the processing of a crypto request which had just completed or
manage the crypto queue to start the next crypto request.
On request R1 completion, the driver calls atmel_sha_finish_req(), which:
1 - clears the 'BUSY' flag since the hardware is no longer used and is
ready again to process new crypto requests.
2 - notifies the above layer (the client) about the completion of the
asynchronous crypto request R1 by calling its base.complete()
callback.
3 - schedules the 'done' task to check the crypto queue and start to
process the next crypto request (the 'BUSY' flag is supposed to be
cleared at that moment) if such a pending request exists.
However step 2 might wake the client up so it can now ask our driver to
process a new crypto request R2. This request is enqueued by calling the
atmel_sha_handle_queue() function, which sets the 'BUSY' flags then
starts to process R2.
If the 'done' tasklet, scheduled by step 3, runs just after, it would see
that the 'BUSY' flag is set then understand that R2 has just completed,
which is wrong!
So the state of 'BUSY' flag is not a proper way to detect and handle
crypto request completion.
This patch fixes this race condition by using two different tasklets, one
to handle the crypto request completion events, the other to manage the
crypto queue if needed.

This patch fixes a crash which occured during the computation of the
digest of an empty message.
Indeed, when processing an empty message, the atmel_sha_handle_queue()
function was never called, hence the dd->req pointer remained
uninitialized.
Later, when the atmel_sha_final_req() function was called, it used
to crash while using this uninitialized dd->req pointer.
Hence this patch adds missing initializations of dd->req before calls of
the atmel_sha_final_req() function.
This bug prevented us from passing the tcrypt test suite on SHA algo.

Commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero")
added a check to prevent ahash algorithms from successfully registering
if the import and export functions were not implemented. This prevents
an oops in the hash_accept function of algif_hash. This commit causes
the ccp-crypto module SHA support and AES CMAC support from successfully
registering and causing the ccp-crypto module load to fail because the
ahash import and export functions are not implemented.
Update the CCP Crypto API support to provide import and export support
for ahash algorithms.

Previous change (see "Fixes" tag) to the MCFGR register
clears AWCACHE[0] ("bufferable" AXI3 attribute) (which is "1" at POR).
This makes all writes non-bufferable, causing a ~ 5% performance drop
for PPC-based platforms.
Rework previous change such that MCFGR[AWCACHE]=4'b0011
(bufferable + cacheable) for all platforms.
Note: For ARM-based platforms, AWCACHE[0] is ignored
by the interconnect IP.

This adds support for the interrupt controller present on PIC32 class
devices. It handles all internal and external interrupts. This controller
exists outside of the CPU core and is the arbitrator of all interrupts
(including interrupts from the CPU itself) before they are presented to
the CPU.
The following features are supported:
- DT properties for EVIC and for devices/peripherals that use interrupt lines
- Persistent and non-persistent interrupt handling
- irqdomain and generic chip support
- Configuration of external interrupt edge polarity

gcc warns about the 'found' variable possibly being used uninitialized:
drivers/soc/qcom/spm.c: In function 'spm_dev_probe':
drivers/soc/qcom/spm.c:305:5: error: 'found' may be used uninitialized in this function [-Werror=maybe-uninitialized]
However, the code is correct because we know that there is
always at least one online CPU. This initializes the 'found'
variable to zero before the loop so the compiler knows
it does not have to warn about it.

If the parameter given to the macro is replaced throughout the macro as
it is evaluated. The intent is that the macro parameter should replace
the only the first parameter to container_of(). However, the way the
macro was written, it would also inadvertantly replace a structure field
name. If a parameter of any other name is given to the macro, it will
fail to compile, if the structure does not contain a field of the same
name. At worst, it will compile, and hide improper access of an
unintended field in the structure.
Change the macro parameter name, so it does not conflict with the
structure field name.

(NTB) device on the Zeppelin platform. The driver connnects to the
standard NTB sub-system interface, with modification to add hooks
for power management in a separate patch. The AMD NTB device has 3
memory windows, 16 doorbell, 16 scratch-pad registers, and supports
up to 16 PCIe lanes running a Gen3 speeds.
