This reverts commit e4f0a7ec586b7644107839f5394fb685cf1aadcc.
When using this new interface, both efi_pstore and ramoops
backends are unable to properly decompress dmesg if using
zstd, lz4 and lzo algorithms (and maybe more). It does succeed
with deflate though.
The message observed in the kernel log is:
[2.328828] pstore: crypto_acomp_decompress failed, ret = -22!
The pstore infrastructure is able to collect the dmesg with
both backends tested, but since decompression fails it's
unreadable. With this revert everything is back to normal.
Fixes: e4f0a7ec586b ("pstore: migrate to crypto acomp interface")

mlx5 xsk updates part2 2022-09-28
XSK buffer improvements, This is part #2 of 4 parts series.
1) Expose xsk min chunk size to drivers, to allow the driver to adjust to a
better buffer stride size
2) Adjust MTT page size to the XSK frame size, to avoid umem overrun in
certain situations.
3) Use xsk frame size as the striding RQ page size for XSK RQs
4) KSM for unaligned XSK, KSM allows arbitrary buffer chunk lengths
registration in HW, which makes more sense for unaligned XSK.
4) More cleanups and optimizations in preparation for next improvements

mlx5e_alloc_unit stores the DMA address and a pointer to either struct
page (regular RQ) or struct xdp_buff (XSK RQ). This DMA address is
redundant, because when a page or an XSK frame is allocated, the same
address is also stored there. Some flows take the address from struct
mlx5e_alloc_unit, and some take it from struct page or xdp_buff.
This commit removes the address from struct mlx5e_alloc_unit, which
makes it twice as small and improves locality (this struct is used in an
array), also saving on unnecessary stores to the addr field. Almost all
flows know unambiguously whether the DMA address should be taken from
page or from xdp_buff. The exception is the allocation flows, where a
new branch appeared, which will be optimized out in the next commits.
struct mlx5e_alloc_unit used to be called mlx5e_dma_info.

The next commit will remove the DMA address from the struct currently
called mlx5e_dma_info, because the same value can be retrieved with
page_pool_get_dma_addr(page) in almost all cases, with the notable
exception of SHAMPO (HW GRO implementation) that modifies this address
on the fly, after the initial allocation.
To keep the SHAMPO logic intact, struct mlx5e_dma_info remains in the
SHAMPO code, consisting of addr and page (XSK is not compatible with
SHAMPO). The struct used in all other places is renamed to
mlx5e_alloc_unit, allowing the next commit to remove the addr field
without affecting SHAMPO.
The new name means "allocation unit", and it's more appropriate after
the field with the DMA address gets removed.

RX page cache stores dma_info structs, that consist of a pointer to
struct page and a DMA address. In fact, the DMA address is extracted
from struct page using page_pool_get_dma_addr when a page is pushed to
the cache. By moving this call to the point when a page is popped from
the cache, we can avoid storing the DMA address in the cache,
effectively reducing its size by two times without losing any
functionality.

WQEs must not cross page boundaries, they are padded with NOPs if they
don't fit the page. mlx5e_mpwrq_total_umr_wqebbs doesn't take into
account this padding, risking reserving not enough space.
The padding is not straightforward to add to this calculation, because
WQEs of different sizes may be mixed together in the queue. If each page
ends with a big WQE that doesn't fit and requires at most its size minus
1 WQEBB of padding, the total space can be much bigger than in case when
smaller WQEs take advantage of this padding.
Replace the wrong exact calculation by the following estimation. Each
padding can be at most the size of the maximum WQE used in the queue
minus one WQEBB. Let's call the rest of the page "useful space". If we
divide the total size of all needed WQEs by this useful space, rounding
up, we'll get the number of pages, which is enough to contain all these
WQEs. It's correct, because every WQE that appeared on the boundary
between two blocks of useful space would start in the useful space of
one page and end in the padding of the same page, while our estimation
reserved space for its tail in the next space, making the estimation not
smaller than the real space occupied in the queue.
The code actually uses a looser estimation: instead of taking the
maximum size of all used WQE types minus 1 WQEBB, it takes the maximum
hardware size of a WQE. It's made for simplicity and extensibility.

UMR MTTs used in striding RQ have certain alignment requirements. While
it's guaranteed to work when UMR pages are aligned to the UMR page size,
in practice it works then UMR pages are aligned to 8 bytes. However,
it's still not enough flexibility for the unaligned mode of XSK. This
patch leverages KSM to map UMR pages without alignment requirements,
when unaligned XSK is active. The downside is that KSM entries are twice
as big as MTTs, which limits the maximum WQE size, so regular RQs and
aligned XSK continue using MTTs.

Currently, rq->mkey_be keeps a big-endian value of either the PA MKey
(for legacy RQ, no address translation) or MTT MKey (for striding RQ,
direct address translation). Striding RQ stores the same value in
rq->umr_mkey in the native endianness.
The next commit will make striding RQ use KSM MKey (indirect address
translation) for the unaligned mode of XSK, which will require storing
both KSM MKey and PA MKey in the RQ struct. This commit optimizes fields
of mlx5e_rq: umr_mkey is removed (it's redundant), mkey_be always points
to the PA MKey, and mpwqe.umr_mkey_be points to the MTT MKey (or to the
KSM MKey, starting from the next commit).

XSK RQs support striding RQ linear mode, but the stride size is always
set to PAGE_SIZE. It may be larger than the XSK frame size,
unnecessarily reducing the useful space in a WQE, but more importantly
causing UMEM data corruption in certain cases.
Normally, stride size bigger than XSK frame size is not a problem if the
hardware enforces the MTU. However, traffic between vports skips the
hardware MTU check, and oversized packets may be received.
If an oversized packet is bigger than the XSK frame but not bigger than
the stride, it will cause overwriting of the adjacent UMEM region. If
the packet takes more than one stride, they can be recycled for reuse
so it's not a problem when the XSK frame size matches the stride size.
To reduce the impact of the above issue, attempt to use the MTT page
size for striding RQ that matches the XSK frame size, allowing to safely
use 2048-byte frames on an up-to-date firmware.

This commit allows striding RQ to determine MTT page size at runtime,
instead of sticking to the compile-time PAGE_SIZE. This functionality
will be used by a following commit that adjusts the MTT page size to the
XSK frame size.
Stick with PAGE_SIZE for XSK on legacy RQ, as frag_stride is not used in
data path, it only helps calculate how pages are partitioned into
fragments, and PAGE_SIZE will ensure each fragment starts at the
beginning of a new allocation unit (XSK frame).

Now that the normal passthrough end_io path doesn't need the request
anymore, we can kill the explicit blk_mq_free_request() and just pass
back RQ_END_IO_FREE instead. This enables the batched completion from
freeing batches of requests at the time.
This brings passthrough IO performance at least on par with bdev based
O_DIRECT with io_uring. With this and batche allocations, peak performance
goes from 110M IOPS to 122M IOPS. For IRQ based, passthrough is now also
about 10% faster than previously, going from ~61M to ~67M IOPS.

With end_io handlers now being able to potentially pass ownership of
the request upon completion, we can allow requests with end_io handlers
in the batch completion handling.

Everything is just converted to returning RQ_END_IO_NONE, and there
should be no functional changes with this patch.
In preparation for allowing the end_io handler to pass ownership back
to the block layer, rather than retain ownership of the request.

The filesystem IO path can take advantage of allocating batches of
requests, if the underlying submitter tells the block layer about it
through the blk_plug. For passthrough IO, the exported API is the
blk_mq_alloc_request() helper, and that one does not allow for
request caching.
Wire up request caching for blk_mq_alloc_request(), which is generally
done without having a bio available upfront.

We've never had any useful reports from this BUG_ON(), and in fact a
number of the BUG_ON()'s in the flush handling need to be turned into
more graceful handling.
In preparation for allowing batched completions of the end_io handling,
where we can enter the flush completion with queuelist having been reused
for the batch, get rid of this BUG_ON().

EHCI Oxynos (drivers/usb/host/ehci-exynos.c) drives VBUS GPIO high when
trying to power up the bus, therefore the GPIO in DTS must be marked as
"active high". This will be important when EHCI driver is converted to
gpiod API that respects declared polarities.

According to s3fwrn5 driver code the "enable" GPIO line is driven "high"
when chip is not in use (mode is S3FWRN5_MODE_COLD), and is driven "low"
when chip is in use.
s3fwrn5_phy_power_ctrl():
...
gpio_set_value(phy->gpio_en, 1);
...
if (mode != S3FWRN5_MODE_COLD) {
msleep(S3FWRN5_EN_WAIT_TIME);
gpio_set_value(phy->gpio_en, 0);
msleep(S3FWRN5_EN_WAIT_TIME);
}
Therefore the line described by "en-gpios" property should be annotated
as "active low".
The wakeup gpio appears to have correct polarity (active high).

1) Use the inner instead of the outer protocol for GSO on inter
address family tunnels. This fixes the GSO case for address
family tunnels. From Sabrina Dubroca.
2) Reset ipcomp_scratches with NULL when freed, otherwise
it holds obsolete address. From Khalid Masum.
3) Reinject transport-mode packets through workqueue
instead of a tasklet. The tasklet might take too
long to finish. From Liu Jian.
Please pull or let me know if there are problems.
