This patch fixes a complain about possible sleep during
spinlock aquired
"BUG: sleeping function called from invalid context at
include/crypto/algapi.h:426"
for the ctr(aes) and ctr(des) s390 specific ciphers.
Instead of using a spinlock this patch introduces a mutex
which is save to be held in sleeping context. Please note
a deadlock is not possible as mutex_trylock() is used.

The pistachio platform uses the U-Boot bootloader & generally boots a
kernel in the uImage format. As such it's useful to build one when
building the kernel, but to do so currently requires the user to
manually specify a uImage target on the make command line.
Make uImage.gz the pistachio platform's default build target, so that
the default is to build a kernel image that we can actually boot on a
board such as the MIPS Creator Ci40.
Marked for stable backport as far as v4.1 where pistachio support was
introduced. This is primarily useful for CI systems such as kernelci.org
which will benefit from us building a suitable image which can then be
booted as part of automated testing, extending our test coverage to the
affected stable branches.

virt_addr_valid() really returns a boolean value, but currently uses an
integer to represent it. Switch to the bool type to make it clearer that
we really are returning a true or false value.

The virt_addr_valid() function is meant to return true iff
virt_to_page() will return a valid struct page reference. This is true
iff the address provided is found within the unmapped address range
between PAGE_OFFSET & MAP_BASE, but we don't currently check for that
condition. Instead we simply mask the address to obtain what will be a
physical address if the virtual address is indeed in the desired range,
shift it to form a PFN & then call pfn_valid(). This can incorrectly
return true if called with a virtual address which, after masking,
happens to form a physical address corresponding to a valid PFN.
For example we may vmalloc an address in the kernel mapped region
starting a MAP_BASE & obtain the virtual address:
addr = 0xc000000000002000
When masked by virt_to_phys(), which uses __pa() & in turn CPHYSADDR(),
we obtain the following (bogus) physical address:
addr = 0x2000
In a common system with PHYS_OFFSET=0 this will correspond to a valid
struct page which should really be accessed by virtual address
PAGE_OFFSET+0x2000, causing virt_addr_valid() to incorrectly return 1
indicating that the original address corresponds to a struct page.
This is equivalent to the ARM64 change made in commit ca219452c6b8
("arm64: Correctly bounds check virt_addr_valid").
This fixes fallout when hardened usercopy is enabled caused by the
related commit 517e1fbeb65f ("mm/usercopy: Drop extra
is_vmalloc_or_module() check") which removed a check for the vmalloc
range that was present from the introduction of the hardened usercopy
feature.

The qpn allocation logic has a WARN_ON() that intends to detect the use of
an index that will introduce bits in the lower order bits of the QOS bits
in the QPN.
Unfortunately, it has the following bugs:
- it misfires when wrapping QPN allocation for non-QOS
- it doesn't correctly detect low order QOS bits (despite the comment)
The WARN_ON() should not be applied to non-QOS (qos_shift == 1).
Additionally, it SHOULD test the qpn bits per the table below:
2 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^
[ 0, 0, 0, 0, 0, 0, sc0], qp bit 1 always 0*
3-4 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^
[ 0, 0, 0, 0, 0, sc1, sc0], qp bits [21] always 0
5-8 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^
[ 0, 0, 0, 0, sc2, sc1, sc0] qp bits [321] always 0
Fix by qualifying the warning for qos_shift > 1 and producing the correct
mask to insure the above bits are zero without generating a superfluous
warning.

Allwinner DAC seems to have a delay in the Speaker audio routing. When
playing a sound for the first time, the sound gets chopped. On a second
play the sound is played correctly. After some time (~5s) the issue gets
back.
This commit seems to be fixing the same issue as bf14da7 but
for another codepath.
This is the DTS that was used to debug the problem.

When initializing a context, the core wants to reset both src and dst
formats. Right now the order doesn't matter, but if we want to have a
valid default width/height on the non-coded/raw format side (src in
case of encoders, dst in case of decoders), we need to reset those
formats in the right order: first the coded-format side, then the other,
such that width and height on the raw format side can be taken from
the coded format.
Let's provide a helper that will reset both formats and make sure this
is done in the right order.

The V4L2/VB2 implementation for the encoder and decoder logic are very
similar, so let's rename rockchip_vpu_enc.c file into
rockchip_vpu_v4l2.c and remove the _enc_ part in objects/functions
exposed in rockchip_vpu_v4l2.h. We also rename the enc_queue_init()
function (in rockchip_vpu_drv.c) queue_init() since it will be used
to initialize both type of queues.
The implementation itself will be patched to support the decoding case
when decoder support is added.

The call to of_parse_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
Detected by coccinelle with the following warnings:
drivers/media/platform/mtk-vpu/mtk_vpu.c:477:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 464, but without a corresponding object release within this function.

As we did a major change on this file, let's take the moment
to cleanup several coding style issues on it.
This patch was partially done with the help of two tools:
./scripts/checkpatch.pl --fix-inplace --strict
astyle --indent=tab=8 --style=linux
But manually adjusted in order to fit our style.

As this driver had a major change, let's take the opportunity
and do some coding style cleanup, in order to make it compliant
with Kernel's style.
This patch was partially done with the help of two tools:
./scripts/checkpatch.pl --fix-inplace --strict
astyle --indent=tab=8 --style=linux
But manually adjusted in order to fit our style.

This is a new file, so the best moment to make it to follow
Kernel coding style is now.
This patch was partially generated with:
./scripts/checkpatch.pl --fix-inplace --strict -f drivers/media/usb/dvb-usb/cxusb-analog.c
And manually checked and adjusted to avoid any warnings.
