Pull s390 fixes from Heiko Carstens:

 - With CONFIG_VMAP_STACK enabled it is not possible to load the s390
   specific diag288_wdt watchdog module. The reason is that a pointer to
   a string is passed to an inline assembly; this string however is
   located on the stack, while the instruction within the inline
   assembly expects a physicial address. Fix this by copying the string
   to a kmalloc'ed buffer.

 - The diag288_wdt watchdog module does not indicate that it accesses
   memory from an inline assembly, which it does. Add "memory" to the
   clobber list to prevent the compiler from optimizing code incorrectly
   away.

 - Pass size of the uncompressed kernel image to __decompress() call.
   Otherwise the kernel image decompressor may corrupt/overwrite an
   initrd. This was reported to happen on s390 after commit 2aa14b1a
   ("zstd: import usptream v1.5.2").

The code expect the PHY to be in power down which is only true after reset.
Allow changes of the SGMII parameters more than once.

Only power down when reconfiguring to avoid bouncing the link when there's
no reason to - based on code from Russell King.

There are cases when the SGMII_PHYA_PWD register contains 0x9 which
prevents SGMII from working. The SGMII still shows link but no traffic
can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
taken from a good working state of the SGMII interface.

When received corrupted snap trace we don't know what exactly has
happened in MDS side. And we shouldn't continue IOs and metadatas
access to MDS, which may corrupt or get incorrect contents.

This patch will just block all the further IO/MDS requests
immediately and then evict the kclient itself.

The reason why we still need to evict the kclient just after
blocking all the further IOs is that the MDS could revoke the caps
faster.

The test tool can check that the zerocopy number of completions value is
valid taking into consideration the number of datagram send calls. This can
catch the system into a state where the datagrams are still in the system
(for example in a qdisk, waiting for the network interface to return a
completion notification, etc).

This change adds a retry logic of computing the number of completions up to
a configurable (via CLI) timeout (default: 2 seconds).

"udpgro_bench.sh" invokes udpgso_bench_rx/udpgso_bench_tx programs
subsequently and while doing so, there is a chance that the rx one is not
ready to accept socket connections. This racing bug could fail the test
with at least one of the following:

./udpgso_bench_tx: connect: Connection refused
./udpgso_bench_tx: sendmsg: Connection refused
./udpgso_bench_tx: write: Connection refused

This change addresses this by making udpgro_bench.sh wait for the rx
program to be ready before firing off the tx one - up to a 10s timeout.

Commit 2dc0b46b ("libata: sata_down_spd_limit should return if
driver has not recorded sstatus speed") changed the behavior of
sata_down_spd_limit() to return doing nothing if a drive does not report
a current link speed, to avoid reducing the link speed to the lowest 1.5
Gbps speed.

However, the change assumed that a speed was recorded before probing
(e.g. before a suspend/resume) and set in link->sata_spd. This causes
problems with adapters/drives combination failing to establish a link
speed during probe autonegotiation. One example reported of this problem
is an mvebu adapter with a 3Gbps port-multiplier box: autonegotiation
fails, leaving no recorded link speed and no reported current link
speed. Probe retries also fail as no action is taken by sata_set_spd()
after each retry.

Fix this by returning early in sata_down_spd_limit() only if we do have
a recorded link speed, that is, if link->sata_spd is not 0. With this
fix, a failed probe not leading to a recorded link speed is retried at
the lower 1.5 Gbps speed, with the link speed potentially increased
later on the second revalidate of the device if the device reports
that it supports higher link speeds.

The timer for the transmission of isotp PDUs formerly had two functions:
1. send two consecutive frames with a given time gap
2. monitor the timeouts for flow control frames and the echo frames

This led to larger txstate checks and potentially to a problem discovered
by syzbot which enabled the panic_on_warn feature while testing.

The former 'txtimer' function is split into 'txfrtimer' and 'txtimer'
to handle the two above functionalities with separate timer callbacks.

The two simplified timers now run in one-shot mode and make the state
transitions (especially with isotp_rcv_echo) better understandable.
