Pull RISC-V fixes from Palmer Dabbelt:
- A fix for an __{get,put}_kernel_nofault to avoid an uninitialized
value causing spurious failures
- compat_vdso.so.dbg is now installed to the standard install location
- A fix to avoid initializing PERF_SAMPLE_BRANCH_*-related events, as
they aren't supported and will just later fail
- A fix to make AT_VECTOR_SIZE_ARCH correct now that we're providing
AT_MINSIGSTKSZ
- pgprot_nx() is now implemented, which fixes vmap W^X protection
- A fix for the vector save/restore code, which at least manifests as
corrupted vector state when a signal is taken
- A fix for a race condition in instruction patching
- A fix to avoid leaking the kernel-mode GP to userspace, which is a
kernel pointer leak that can be used to defeat KASLR in various ways
- A handful of smaller fixes to build warnings, an overzealous printk,
and some missing tracing annotations

Pull thermal control fixes from Rafael Wysocki:
"These fix two power allocator thermal governor issues and an ACPI
thermal driver regression that all were introduced during the 6.8
development cycle.
Specifics:
- Allow the power allocator thermal governor to bind to a thermal

Travkin)
- Make the ACPI thermal driver register a tripless thermal zone when
it cannot find any usable trip points instead of returning an error
from acpi_thermal_add() (Stephen Horvath)"

Pull vfs fixes from Christian Brauner:
"This contains a few small fixes. This comes with some delay because I
wanted to wait on people running their reproducers and the Easter
Holidays meant that those replies came in a little later than usual:
- Fix handling of preventing writes to mounted block devices.
Since last kernel we allow to prevent writing to mounted block
devices provided CONFIG_BLK_DEV_WRITE_MOUNTED isn't set and the
block device is opened with restricted writes. When we switched to
opening block devices as files we altered the mechanism by which we
recognize when a block device has been opened with write
restrictions.
The detection logic assumed that only read-write mounted
filesystems would apply write restrictions to their block devices
from other openers. That of course is not true since it also makes
sense to apply write restrictions for filesystems that are
read-only.
Fix the detection logic using an FMODE_* bit. We still have a few
left since we freed up a couple a while ago. I also picked up a
patch to free up four additional FMODE_* bits scheduled for the
next merge window.
- Fix counting the number of writers to a block device. This just
changes the logic to be consistent.
- Fix a bug in aio causing a NULL pointer derefernce after we
implemented batched processing in aio.
- Finally, add the changes we discussed that allows to yield block
devices early even though file closing itself is deferred.
This also allows us to remove two holder operations to get and
release the holder to align lifetime of file and holder of the
block device"

When adding sanitization of the label, the path through
edge_detector_setup() that leads to debounce_setup() was overlooked.
A request taking this path does not allocate a new label and the
request label is freed twice when the request is released, resulting
in memory corruption.
Add label sanitization to debounce_setup().

After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two
consecutive device resets"), reset is not executed from bind operation and
mac address is not read from the device registers or the devicetree at that
moment. Since the check to configure if the assigned mac address is random
or not for the interface, happens after the bind operation from
usbnet_probe, the interface keeps configured as random address, although the
address is correctly read and set during open operation (the only reset
now).
In order to keep only one reset for the device and to avoid the interface
always configured as random address, after reset, configure correctly the
suitable field from the driver, if the mac address is read successfully from
the device registers or the devicetree. Take into account if a locally
administered address (random) was previously stored.

We need to take into account that a line's consumer label may be NULL
and not try to kstrdup() it in that case but rather pass the NULL
pointer up the stack to the interrupt request function.
To that end: let make_irq_label() return NULL as a valid return value
and use ERR_PTR() instead to signal an allocation failure to callers.

Preempt fences can sleep waiting for an exec queue suspend operation to
complete. If the system_unbound_wq is used for waiting and the number of
waiters exceeds max_active this will result in other users of the
system_unbound_wq getting starved. Use a device private work queue for
preempt fences to avoid starvation of the system_unbound_wq.
Even though suspend operations can complete out-of-order, all suspend
operations within a VM need to complete before the preempt rebind worker
can start. With that, use a device private ordered wq for preempt fence
waiting.

For each rebind we insert a GuC TLB invalidation and add a
corresponding unordered TLB invalidation fence. This might
add a huge number of TLB invalidation fences to wait for so
rather than doing that, defer the TLB invalidation to the
next ring ops for each affected exec queue. Since the TLB
is invalidated on exec_queue switch, we need to invalidate
once for each affected exec_queue.

- Simplify if-statements around the tlb_flush_seqno.

- Add some comments and asserts.

Knowing that sja1110_pcs_mdio_write_c45() is used as a function pointer

int (*pcs_mdio_write_c45)(struct mii_bus *bus, int phy, int mmd,

The error statistics should be updated each time the poll function is
called, even if the full RX work budget has been consumed. This prevents
the counts from becoming stuck when RX bandwidth usage is high.
This also ensures that error counters are not updated after we've
re-enabled interrupts as that could result in a race condition.
Also drop an unnecessary space.

mana_get_rxbuf_cfg() aligns the RX buffer's DMA datasize to be
multiple of 64. So a packet slightly bigger than mtu+14, say 1536,
can be received and cause skb_over_panic.

There are 2 issues with the blamed commit.
1. When the phy is initialized, it would enable the disabled of UDPv4
checksums. The UDPv6 checksum is already enabled by default. So when
1-step is configured then it would clear these flags.
2. After the 1-step is configured, then if 2-step is configured then the
1-step would be still configured because it is not clearing the flag.
So the sync frames will still have origin timestamps set.
Fix this by reading first the value of the register and then
just change bit 12 as this one determines if the timestamp needs to
be inserted in the frame, without changing any other bits.

The driver should ensure that same priority is not mapped to multiple
rx queues. From DesignWare Cores Ethernet Quality-of-Service
Databook, section 17.1.29 MAC_RxQ_Ctrl2:
"[...]The software must ensure that the content of this field is
mutually exclusive to the PSRQ fields for other queues, that is,
the same priority is not mapped to multiple Rx queues[...]"
Previously rx_queue_priority() function was:
- clearing all priorities from a queue
- adding new priorities to that queue
After this patch it will:
- first assign new priorities to a queue
- then remove those priorities from all other queues
- keep other priorities previously assigned to that queue

Setting mac_managed_pm during interface up is too late.
In situations where the link is not brought up yet and the system suspends
the regular PHY power management will run. Since the FEC ETHEREN control
bit is cleared (automatically) on suspend the controller is off in resume.
When the regular PHY power management resume path runs in this context it
will write to the MII_DATA register but nothing will be transmitted on the
MDIO bus.
This can be observed by the following log:
fec 5b040000.ethernet eth0: MDIO read timeout
Microchip LAN87xx T1 5b040000.ethernet-1:04: PM: dpm_run_callback(): mdio_bus_phy_resume+0x0/0xc8 returns -110
Microchip LAN87xx T1 5b040000.ethernet-1:04: PM: failed to resume: error -110
The data written will however remain in the MII_DATA register.
When the link later is set to administrative up it will trigger a call to
fec_restart() which will restore the MII_SPEED register. This triggers the
quirk explained in f166f890c8f0 ("net: ethernet: fec: Replace interrupt
driven MDIO with polled IO") causing an extra MII_EVENT.
This extra event desynchronizes all the MDIO register reads, causing them
to complete too early. Leading all reads to read as 0 because
fec_enet_mdio_wait() returns too early.
When a Microchip LAN8700R PHY is connected to the FEC, the 0 reads causes
the PHY to be initialized incorrectly and the PHY will not transmit any
ethernet signal in this state. It cannot be brought out of this state
without a power cycle of the PHY.

In the very rare case where a packet type is unknown to the driver,
idpf_rx_process_skb_fields would return early without calling
eth_type_trans to set the skb protocol / the network layer handler.
This is especially problematic if tcpdump is running when such a
packet is received, i.e. it would cause a kernel panic.
Instead, call eth_type_trans for every single packet, even when
the packet type is unknown.

The MST code currently assumes that glk+ already supports MST+DSC,
which is incorrect. We need to check for TGL+ actually. ICL does
support SST+DSC, but supposedly it can't do MST+FEC which will
also rule out MST+DSC.
Note that a straight TGL+ check doesn't work here because DSC
support can get fused out, so we do need to also check 'has_dsc'.

IPA probe function was recently refactored to perform extra error checks
and make sure the thermal zone has trip points necessary for the IPA
operation. With this change, if a thermal zone is probed such that it
has no trip points that IPA can use, IPA will fail and the TZ won't be
created. This is the case if a platform defines a TZ without cooling
devices and only with "hot"/"critical" trip points, often found on some
Qualcomm devices [1].
Documentation across IPA code (notably get_governor_trips() kerneldoc)
suggests that IPA is supposed to handle such TZ even if it won't
actually do anything.
This commit partially reverts the previous change to allow IPA to bind
to such "empty" thermal zones.

IPA was recently refactored to split out memory allocation into a
separate funciton. That funciton was made to return -EINVAL if there is
zero power_actors and thus no memory to allocate. This causes IPA to
fail probing when the thermal zone has no attached cooling devices.
Since cooling devices can attach after the thermal zone is created and
the governer is attached to it, failing probe due to the lack of cooling
devices is incorrect.
Change the allocate_actors_buffer() to return success when there is no
cooling devices present.

kobject_get() errors
When a gpiochip gets added by loading a module, then another driver may
be waiting for that gpiochip to load on the deferred-probe list.
If the deferred-probe for the consumer of gpiochip then triggers between
the gpiodev_add_to_list_unlocked() calls which makes gpio_device_find()
see the chip and the gpiochip_setup_dev() later then gpio_device_find()
does a kobject_get() on an uninitialized kobject since the kobject is
initialized by gpiochip_setup_dev() calling device_initialize():

If the RBUF logic is not reset when the kernel starts then there
may be some data left over from any network boot loader. If the
64-byte packet headers are enabled then this can be fatal.
Extend bcmgenet_dma_disable to do perform the reset, but not when
called from bcmgenet_resume in order to preserve a wake packet.
N.B. This different handling of resume is just based on a hunch -
why else wouldn't one reset the RBUF as well as the TBUF? If this
isn't the case then it's easy to change the patch to make the RBUF
reset unconditional.
