a510b61613 MIPS: Add support for ZSTD-compressed kernels
Add support for self-extracting kernels with a ZSTD compression.

Tested on a kernel for the GCW-Zero, it allows to reduce the size of the
kernel file from 4.1 MiB with gzip to 3.5 MiB with ZSTD, and boots just
as fast.

Compressed kernels are now also compiled with -D__DISABLE_EXPORTS in
order to disable the EXPORT_SYMBOL() macros inside of
lib/zstd/decompress.c.

1c4dd334df lib: decompress_unzstd: Limit output size
The zstd decompression code, as it is right now, will most likely fail
on 32-bit systems, as the default output buffer size causes the buffer's
end address to overflow.

Address this issue by setting a sane default to the default output size,
with a value that won't overflow the buffer's end address.

After commit 70b838292b ("MIPS: Update default config file for
Loongson-3"), CONFIG_VHOST_SCSI and CONFIG_VHOST are set when use
loongson3_defconfig, and then there exists the following two build
warnings related with these two configs:

  CC [M]  drivers/vhost/scsi.o
drivers/vhost/scsi.c: In function ‘vhost_scsi_flush’:
drivers/vhost/scsi.c:1374:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]

 }
 ^

CONFIG_FRAME_WARN=2048 can fix it, since the default CONFIG_FRAME_WARN
for 64BIT is 2048, just delete the CONFIG_FRAME_WARN line in defconfig.

Commit 1355c31eeb ("asm-generic: pgalloc: provide generic pmd_alloc_one()

pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for
PMD.

Restore the original version of pmd_alloc_one() for parisc, just use
GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and
memset.

d4e7cd36a9 io_uring: sanitize double poll handling
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.
