io_arm_poll_handler() will recycle the buffer appropriately if we end
up arming poll (or if we're ready to retry), but not for the io-wq case
if we have attempted poll first.

Explicitly recycle the buffer to avoid both hanging on to it too long,
but also to avoid multiple reads grabbing the same one. This can happen
for ring mapped buffers, since it hasn't necessarily been committed.

For recv/recvmsg, IO either completes immediately or gets queued for a
retry. This isn't the case for read/readv, if eg a normal file or a block
device is used. Here, an operation can get queued with the block layer.
If this happens, ring mapped buffers must get committed immediately to
avoid that the next read can consume the same buffer.

Check if we're dealing with pollable file, when getting a new ring mapped
provided buffer. If it's not, commit it immediately rather than wait post
issue. If we don't wait, we can race with completions coming in, or just
plain buffer reuse by committing after a retry where others could have
grabbed the same buffer.

Pull random number generator fixes from Jason Donenfeld:

 - A fix for a 5.19 regression for a case in which early device tree
   initializes the RNG, which flips a static branch.

   On most plaforms, jump labels aren't initialized until much later, so
   this caused splats. On a few mailing list threads, we cooked up easy
   fixes for arm64, arm32, and risc-v. But then things looked slightly
   more involved for xtensa, powerpc, arc, and mips. And at that point,
   when we're patching 7 architectures in a place before the console is
   even available, it seems like the cost/risk just wasn't worth it.

   So random.c works around it now by checking the already exported
   `static_key_initialized` boolean, as though somebody already ran into
   this issue in the past. I'm not super jazzed about that; it'd be
   prettier to not have to complicate downstream code. But I suppose
   it's practical.

 - A few small code nits and adding a missing __init annotation.

 - A change to the default config values to use the cpu and bootloader's
   seeds for initializing the RNG earlier.

   This brings them into line with what all the distros do (Fedora/RHEL,
   Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
   least), and moreover will now give us test coverage in various test
   beds that might have caught the above device tree bug earlier.

 - A change to WireGuard CI's configuration to increase test coverage
   around the RNG.

 - A documentation comment fix to unrelated maintainerless CRC code that
   I was asked to take, I guess because it has to do with polynomials
   (which the RNG thankfully no longer uses).

WMI queries fail on some devices where the ACPI method HWMC
unconditionally attempts to create Fields beyond the buffer
if the buffer is too small, this breaks essential features
such as power profiles:

         CreateByteField (Arg1, 0x10, D008)
         CreateByteField (Arg1, 0x11, D009)
         CreateByteField (Arg1, 0x12, D010)
         CreateDWordField (Arg1, 0x10, D032)
         CreateField (Arg1, 0x80, 0x0400, D128)

In cases where args->data had zero length, ACPI BIOS Error
(bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit
offset/length 128/8 exceeds size of target Buffer (128 bits)
(20211217/dsopcode-198) was obtained.

ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit
offset/length 136/8 exceeds size of target Buffer (136bits)
(20211217/dsopcode-198)

The original code created a buffer size of 128 bytes regardless if
the WMI call required a smaller buffer or not.  This particular
behavior occurs in older BIOS and reproduced in OMEN laptops.  Newer
BIOS handles buffer sizes properly and meets the latest specification
requirements.  This is the reason why testing with a dynamically
allocated buffer did not uncover any failures with the test systems at
hand.

This patch was tested on several OMEN, Elite, and Zbooks.  It was
confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN
Laptop 15-ek0xxx.  No problems were reported when testing on several Elite
