engine->stat_irq_thresh was initialized after device_create_file() in

Once the crypto hash walk is started by crypto_hash_walk_first()
returning non-zero, crypto_hash_walk_done() must be called to unmap any
memory which was mapped by *_walk_first().
Ensure crypto_hash_walk_done() is called properly by:
1) Re-arranging the check for device data to be prior to calling
*_walk_first()
2) on error call crypto_hash_walk_done() with an error code to
allow the hash walk code to clean up.
While we are at it clean up the 'out' label to be more meaningful.

Currently the debugfs fops are defined in caam/intern.h. This causes
problems because it creates identical static functions and variables
in multiple files. It also creates warnings when those files don't
use the fops.

It also removes unnecessary uses of ifdefs on CONFIG_DEBUG_FS.

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:
12a: 48 8b 08 mov (%rax),%rcx
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
13a: 75 ee jne 12a <crc32c_intel_update+0x1a>
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.
v2: Introduce CRC32_INST define.

This patch fixes most sparse warnings in the cesa driver. The only
ones remaining are to do with copying data between iomem pointers and
SG lists.
Most changes are trivial. The following are the noteworthy ones:
- Removal of swab in mv_cesa_aes_setkey. This appears to be bogus
as everything gets swabbed again later on so for BE this ends up
being different from LE. The change takes the LE behaviour as the
correct one.
- next_dma in mv_cesa_tdma_chain was not swabbed.

The power keeps going on here so I haven't have a chance to give this the

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.
Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().
Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
works), fixes will be provided soon.
clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.

Pull more perf tools updates from Arnaldo Carvalho de Melo:
"Fixes:
- Fixes for 'perf bench numa'.
- Always memset source before memcpy in 'perf bench mem'.
- Quote CC and CXX for their arguments to fix build in environments
using those variables to pass more than just the compiler names.
- Fix module symbol processing, addressing regression detected via
"perf test".
- Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
test' entry.
Improvements:
- Add script to autogenerate socket family name id->string table from
copy of kernel header, used so far in 'perf trace'.
- 'perf ftrace' improvements to provide similar options for this
utility so that one can go from 'perf record', 'perf trace', etc to
'perf ftrace' just by changing the name of the subcommand.
- Prefer new "sched:sched_waking" trace event when it exists in 'perf
sched' post processing.
- Update POWER9 metrics to utilize other metrics.
- Fall back to querying debuginfod if debuginfo not found locally.
Miscellaneous:
- Sync various kvm headers with kernel sources"

Patch series "iomap: Constify ioreadX() iomem argument", v3.
The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.
It seems there is nothing really stopping all of them to take pointer to
const.
This patch (of 4):
The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On
some architectures void *__iomem address argument is a pointer to const,
on some not.
Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.
