Linus Torvalds 3abc3ae553 9p-for-5.19-rc4: fid refcount and fscache fixes
This contains a couple of fixes:
  - fid refcounting was incorrect in some corner cases and would
 leak resources, only freed at umount time. The first three commits
 fix three such cases
  - cache=loose or fscache was broken when trying to write a partial
 page to a file with no read permission since the rework a few releases
 ago. The fix taken here is just to restore old behavior of using the
 special 'writeback_fid' for such reads, which is open as root/RDWR
 and such not get complains that we try to read on a WRONLY fid.
 Long-term it'd be nice to get rid of this and not issue the read at
 all (skip cache?) in such cases, but that direction hasn't progressed

Jakub Kicinski 877fe9d49b Revert "drivers/net/ethernet/neterion/vxge: Fix a use-after-free bug in vxge-main.c"
This reverts commit 8fc74d1863.

BAR0 is the main (only?) register bank for this device. We most
obviously can't unmap it before the netdev is unregistered.
This was pointed out in review but the patch got reposted and
merged, anyway.

The author of the patch was only testing it with a QEMU model,
which I presume does not emulate enough for the netdev to be brought
up (author's replies are not visible in lore because they kept sending
their emails in HTML).

regmap-irq: Fix a bug in regmap_irq_enable() for type_in_mask chips
When enabling a type_in_mask irq, the type_buf contents must be
AND'd with the mask of the IRQ we're enabling to avoid enabling
other IRQs by accident, which can happen if several type_in_mask
irqs share a mask register.

CQ Tang d976521a99 drm/i915: extend i915_vma_pin_iomap()
In the future display might try call this with a normal smem object,
which doesn't require PIN_MAPPABLE underneath in order to CPU map the
pages (unlike stolen).  Extend i915_vma_pin_iomap() to directly use
i915_gem_object_pin_map() for such cases.

This change was suggested by Chris P Wilson, that we pin
the smem with i915_gem_object_pin_map_unlocked().

Jason A. Donenfeld f3eac42665 powerpc/powernv: wire up rng during setup_arch
The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call.

Complicating things, however, is that POWER8 systems need some per-cpu
state and kmalloc, which isn't available at this stage. So we split
things up into an early phase and a later opportunistic phase. This
commit also removes some noisy log messages that don't add much.

Johan Hovold ae60aac59a USB: serial: pl2303: add support for more HXN (G) types
Add support for further HXN (G) type devices (GT variant, GL variant, GS
variant and GR) and document the bcdDevice mapping.

Note that the TA and TB types use the same bcdDevice as some GT and GE
variants, respectively, but that the HX status request can be used to
determine which is which.

Also note that we currently do not distinguish between the various HXN
(G) types in the driver but that this may change eventually (e.g. when
adding GPIO support).

Lukas Wunner 2642cc6c3b net: phy: smsc: Disable Energy Detect Power-Down in interrupt mode
Simon reports that if two LAN9514 USB adapters are directly connected
without an intermediate switch, the link fails to come up and link LEDs
remain dark.  The issue was introduced by commit 1ce8b37241 ("usbnet:
smsc95xx: Forward PHY interrupts to PHY driver to avoid polling").

The PHY suffers from a known erratum wherein link detection becomes
unreliable if Energy Detect Power-Down is used.  In poll mode, the
driver works around the erratum by briefly disabling EDPD for 640 msec
to detect a neighbor, then re-enabling it to save power.

In interrupt mode, no interrupt is signaled if EDPD is used by both link
partners, so it must not be enabled at all.

We'll recoup the power savings by enabling SUSPEND1 mode on affected
LAN95xx chips in a forthcoming commit.

Pavel Begunkov c0737fa9a5 io_uring: fix double poll leak on repolling
We have re-polling for partial IO, so a request can be polled twice. If
it used two poll entries the first time then on the second
io_arm_poll_handler() it will find the old apoll entry and NULL
kmalloc()'ed second entry, i.e. apoll->double_poll, so leaking it.

Anatolii Gerasymenko a632b2a4c9 ice: ethtool: Prohibit improper channel config for DCB
Do not allow setting less channels, than Traffic Classes there are
via ethtool. There must be at least one channel per Traffic Class.

If you set less channels, than Traffic Classes there are, then during
ice_vsi_rebuild there would be allocated only the requested amount
of tx/rx rings in ice_vsi_alloc_arrays. But later in ice_vsi_setup_q_map
there would be requested at least one channel per Traffic Class. This
results in setting num_rxq > alloc_rxq and num_txq > alloc_txq.
Later, there would be a NULL pointer dereference in
ice_vsi_map_rings_to_vectors, because we go beyond of rx_rings or
tx_rings arrays.

Change ice_set_channels() to return error if you try to allocate less
channels, than Traffic Classes there are.
Change ice_vsi_setup_q_map() and ice_vsi_setup_q_map_mqprio() to return
status code instead of void.
Add error handling for ice_vsi_setup_q_map() and
ice_vsi_setup_q_map_mqprio() in ice_vsi_init() and ice_vsi_cfg_tc().

Chaitanya Dhere aeb73c608c drm/amd/display: Implement a pme workaround function
[Why]
For DCN32 we do not have a pme workaround function defined that sends a
BacoAudio message. Default code had uses the DCN30 function for pme
workaround. PMFW headers are inconsistent with their message ID
definitions which cause ID's to clash leading to inconsistent system
behaviour. There is a clash with FCLK message due to inconsitent PMFW
headers.

[How]
Implement a new BacoAudio function to workaround the problem of
inconsistent PMFW headers in order to avoid BacoAudio message clasing
with FCLK Enable message.

George Shen a3a885878e drm/amd/display: Fix divide-by-zero in DPPCLK and DISPCLK calculation
[Why]
Certain use cases will pass in zero in the new_clocks parameter for all
clocks. This results in a divide-by-zero error when attempting to round
up the new clock.

When new_clocks are zero, no rounding is required, so we can skip it.

[How]
Guard the division calculation with a check to make sure clocks are not
zero.

Alvin Lee 04e6931a76 drm/amd/display: Update DPPCLK programming sequence
[Description]
- When lowering DPPCLK, we want to program the DPP DTO before updating
the DPP refclk.
- Also update DPPCLK to the exact frequency that will be set after clock
divider has been programmed. This will prevent rounding errors when
making the request to PMFW (we need DPP DTO to match exactly with the
exact DPP refclk).
