This patch fixes most of the sparse endianness warnings in stm32.
The patch itself doesn't change anything apart from markings,
but there is some questionable code in stm32_cryp_check_ctr_counter.
That function operates on the counters as if they're in CPU order,
however, they're then written out as big-endian. This looks like
a genuine bug. Therefore I've left that warning alone until
someone can confirm that this really does work as intended on
little-endian.

pm_runtime_get_sync() increments the runtime PM usage counter
even when it returns an error code. However, users of cc_pm_get(),
a direct wrapper of pm_runtime_get_sync(), assume that PM usage
counter will not change on error. Thus a pairing decrement is needed
on the error handling path to keep the counter balanced.

This patch squashes all the sparse warnings in mediatek, some of
which appear to be genuine bugs. In particular, previously on
BE the keys and IVs all get 32-bit swabbed which can't be right
because they don't get swabbed on LE. I presume LE is the one
that actually works.
Another funky thing is that the GHASH key gets swabbed on LE.
This makes no sense but I'm presuming someone actually tested
this on LE so I'm preserving the swabbing. Someone needs to
test this though as it is entirely possible that GCM is the
only thing that worked on BE but not LE.

When the devices are removed or not existing, the corresponding algorithms
which are registered by 'hisi-zip' driver can't be used.
Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to
'hisi_zip_probe'. The algorithms will be registered to crypto only when
there is device bind on the driver. And when the devices are removed,
the algorithms will be unregistered.
In the previous process, the function 'xxx_register_to_crypto' need a lock
and a static variable to judge if the registration is the first time.

The current code waits for data to be available before attempting a
second read. However the second read would not be executed as the
while loop will exit.
This fix does not wait if all data has been read (skips the call to
msleep(0)) and reads a second time if partial data was retrieved on
the first read.
Worth noticing that since msleep(0) schedules a one jiffy timeout is
better to skip such a call.

Current minimum required version of binutils is 2.23,
which supports CRC32 instruction mnemonic.
Replace the byte-wise specification of CRC32 with this proper mnemonic.
The compiler is now able to pass memory operand to the instruction,
so there is no need for a temporary register anymore.
Some examples of the improvement:

12d: f2 48 0f 38 f1 f1 crc32q %rcx,%rsi
133: 48 83 c0 08 add $0x8,%rax
137: 48 39 d0 cmp %rdx,%rax

to:
125: f2 48 0f 38 f1 06 crc32q (%rsi),%rax
12b: 48 83 c6 08 add $0x8,%rsi
12f: 48 39 d6 cmp %rdx,%rsi
132: 75 f1 jne 125 <crc32c_intel_update+0x15>
and:
146: 0f b6 08 movzbl (%rax),%ecx
149: f2 0f 38 f0 f1 crc32b %cl,%esi
14e: 48 83 c0 01 add $0x1,%rax
152: 48 39 d0 cmp %rdx,%rax
155: 75 ef jne 146 <crc32c_intel_update+0x36>
to:
13b: f2 0f 38 f0 02 crc32b (%rdx),%eax
140: 48 83 c2 01 add $0x1,%rdx
144: 48 39 ca cmp %rcx,%rdx
147: 75 f2 jne 13b <crc32c_intel_update+0x2b>
As the compiler has some more freedom w.r.t. register allocation,
there is also a couple of reg-reg moves removed.
There are no hidden states for CRC32 insn, so there is no need to mark
assembly as volatile.

Merge tag 'io_uring-5.9-2020-08-15' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"A few differerent things in here.
Seems like syzbot got some more io_uring bits wired up, and we got a
handful of reports and the associated fixes are in here.
General fixes too, and a lot of them marked for stable.
Lastly, a bit of fallout from the async buffered reads, where we now
more easily trigger short reads. Some applications don't really like
that, so the io_read() code now handles short reads internally, and
got a cleanup along the way so that it's now easier to read (and
documented). We're now passing tests that failed before"
