Pull arm64 fixes from Will Deacon:
"A bumper crop of arm64 fixes for -rc3.
The largest change is fixing our parsing of the 'rodata=full' command
line option, which kstrtobool() started treating as 'rodata=false'.
The fix actually makes the parsing of that option much less fragile
and updates the documentation at the same time.
We still have a boot issue pending when KASLR is disabled at compile
time, but there's a fresh fix on the list which I'll send next week if
it holds up to testing.
Summary:
- Fix workaround for Cortex-A76 erratum #1286807
- Add workaround for AMU erratum #2457168 on Cortex-A510
- Drop reference to removed CONFIG_ARCH_RANDOM #define
- Fix parsing of the "rodata=full" cmdline option
- Fix a bunch of issues in the SME register state switching and sigframe code
- Fix incorrect extraction of the CTR_EL0.CWG register field
- Fix ACPI cache topology probing when the PPTT is not present
- Trivial comment and whitespace fixes"

There are several places in the kernel where wait_on_bit is not followed
by a memory barrier (for example, in drivers/md/dm-bufio.c:new_read).
On architectures with weak memory ordering, it may happen that memory
accesses that follow wait_on_bit are reordered before wait_on_bit and
they may return invalid data.
Fix this class of bugs by introducing a new function "test_bit_acquire"
that works like test_bit, but has acquire memory ordering semantics.

Microchip RISC-V devicetree fixes for 6.0-rc3
Two sets of fixes this time around:
- A fix for the interrupt ordering of the l2-cache controller. If the
driver is enabled, it would spam the console /constantly/, rendering
the system useless.
- General cleanup for some bogus properties in the dt, part of my quest
for zero dtbs_check warnings.
On that note, the interrupt ordering adds a dtbs_check warning - but I
considered that fixing the potentially useless system was more of a
priority.

net: lantiq_xrx200: fix errors under memory pressure
This series fixes issues that can occur in the driver under memory pressure.
Situations when the system cannot allocate memory are rare, so the mentioned
bugs have been fixed recently. The patches have been tested on a BT Home
router with the Lantiq xRX200 chipset.
Changelog:
v3: - removed netdev_err() log from the first patch
v2:
- the second patch has been changed, so that under memory pressure situation
the driver will not receive packets indefinitely regardless of the NAPI budget,
- the third patch has been added.

When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll
function immediately returns an error.
This is incorrect for two reasons:
* the function terminates without enabling interrupts or scheduling NAPI,
* the error code (-ENOMEM) is returned instead of the number of received
packets.
After the first memory allocation failure occurs, packet reception is
locked due to disabled interrupts from DMA..

This is a follow-up to the discussion in [0]. It seems to me that
at least the IP version used on Amlogic SoC's sometimes has a problem
if register MAC_CTRL_REG is written whilst the chip is still processing
a previous write. But that's just a guess.
Adding a delay between two writes to this register helps, but we can
also simply omit the offending second write. This patch uses the second
approach and is based on a suggestion from Qi Duan.
Benefit of this approach is that we can save few register writes, also
on not affected chip versions.

Assign a random mac address to the VF interface station
address if it boots with a zero mac address in order to match
similar behavior seen in other VF drivers. Handle the errors
where the older firmware does not allow the VF to set its own
station address.
Newer firmware will allow the VF to set the station mac address
if it hasn't already been set administratively through the PF.
Setting it will also be allowed if the VF has trust.

FW_ACTIVATE_STATUS command fail while it is in its EAGAIN loop
waiting for the FW activate step to finsh inside the FW. The
firmware is complaining that the done bit is set when a new
dev_cmd is going to be processed.
Doing a clean on the cmd registers and doorbell before exiting
the wait-for-done and cleaning the done bit before the sleep
prevents this from occurring.

There is a case found in heavy testing where a link flap happens just
before a firmware Recovery event and the driver gets stuck in the
BROKEN state. This comes from the driver getting interrupted by a FW
generation change when coming back up from the link flap, and the call
to ionic_start_queues() in ionic_link_status_check() fails. This can be
addressed by having the fw_up code clear the BROKEN bit if seen, rather
than waiting for a user to manually force the interface down and then
back up.

Fix three bugs in the rxrpc's sendmsg implementation:
(1) rxrpc_new_client_call() should release the socket lock when returning
an error from rxrpc_get_call_slot().
(2) rxrpc_wait_for_tx_window_intr() will return without the call mutex
held in the event that we're interrupted by a signal whilst waiting
for tx space on the socket or relocking the call mutex afterwards.
Fix this by: (a) moving the unlock/lock of the call mutex up to
rxrpc_send_data() such that the lock is not held around all of
rxrpc_wait_for_tx_window*() and (b) indicating to higher callers
whether we're return with the lock dropped. Note that this means
recvmsg() will not block on this call whilst we're waiting.
(3) After dropping and regaining the call mutex, rxrpc_send_data() needs
to go and recheck the state of the tx_pending buffer and the
tx_total_len check in case we raced with another sendmsg() on the same
call.
Thinking on this some more, it might make sense to have different locks for
sendmsg() and recvmsg(). There's probably no need to make recvmsg() wait
for sendmsg(). It does mean that recvmsg() can return MSG_EOR indicating
that a call is dead before a sendmsg() to that call returns - but that can
currently happen anyway.
Without fix (2), something like the following can be induced:
WARNING: bad unlock balance detected!

When translate_further is enabled, page table depth needs to
be updated. This was missing on Arcturus MMHUB init. This was
causing address translations to fail for SDMA user-mode queues.

We usually copy all bits that a request needs from the userspace for
async execution, so the userspace can keep them on the stack. However,
send zerocopy violates this pattern for addresses and may reloads it
e.g. from io-wq. Save the address if any in ->async_data as usual.

LoongArch only support 32-bit/64-bit xchg/cmpxchg in native. But percpu
operation, qspinlock and some drivers need 8-bit/16-bit xchg/cmpxchg. We
add subword xchg/cmpxchg emulation in this patch because the emulation
has better performance than the generic implementation (on NUMA system),
and it can fix some build errors meanwhile [1].
LoongArch's guarantee for forward progress (avoid many ll/sc happening
at the same time and no one succeeds):
We have the "exclusive access (with timeout) of ll" feature to avoid
simultaneous ll (which also blocks other memory load/store on the same
address), and the "random delay of sc" feature to avoid simultaneous
sc. It is a mandatory requirement for multi-core LoongArch processors
to implement such features, only except those single-core and dual-core
processors (they also don't support multi-chip interconnection).
Feature bits are introduced in CPUCFG3, bit 3 and bit 4 [2].

When enable GENERIC_IOREMAP, there will be circular dependency to cause
build errors. The root cause is that pgtable.h shouldn't include io.h
but pgtable.h need some macros defined in io.h. So cleanup those macros
and remove the unnecessary inclusions, as other architectures do.

entry points, from Florian Westphal.
2) Fix possible TCP connection clogging up with default 5-days
timeout in conntrack, from Florian.
3) Fix crash in nf_tables tproxy with unsupported chains, also from Florian.
4) Do not allow to update implicit chains.
5) Make table handle allocation per-netns to fix data race.
6) Do not truncated payload length and offset, and checksum offset.
Instead report EINVAl.
7) Enable chain stats update via static key iff no error occurs.
8) Restrict osf expression to ip, ip6 and inet families.
9) Restrict tunnel expression to netdev family.
10) Fix crash when trying to bind again an already bound chain.
11) Flowtable garbage collector might leave behind pending work to
delete entries. This patch comes with a previous preparation patch
as dependency.
12) Allow net.netfilter.nf_conntrack_frag6_high_thresh to be lowered,
from Eric Dumazet.

The ixgbe_ptp_start_cyclecounter is intended to be called whenever the
cyclecounter parameters need to be changed.
Since commit a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x
devices"), this function has cleared the SYSTIME registers and reset the
TSAUXC DISABLE_SYSTIME bit.
While these need to be cleared during ixgbe_ptp_reset, it is wrong to clear
them during ixgbe_ptp_start_cyclecounter. This function may be called
during both reset and link status change. When link changes, the SYSTIME
counter is still operating normally, but the cyclecounter should be updated
to account for the possibly changed parameters.
Clearing SYSTIME when link changes causes the timecounter to jump because
the cycle counter now reads zero.
Extract the SYSTIME initialization out to a new function and call this
during ixgbe_ptp_reset. This prevents the timecounter adjustment and avoids
an unnecessary reset of the current time.
This also restores the original SYSTIME clearing that occurred during
ixgbe_ptp_reset before the commit above.
