If ops->set_phys_id() returned an error, previously we would only break
out of the inner loop, which neither stopped the outer loop nor returned
the error to the user (since 'rc' would be overwritten on the next pass
through the loop).
Thus, rewrite it to use a single loop, so that the break does the right
thing. Use u64 for 'count' and 'i' to prevent overflow in case of
(unreasonably) large values of id.data and n.

While CHELSIO_INLINE_CRYPTO is a guard symbol, and just enabling it does
not cause any additional code to be compiled in, all configuration
options protected by it depend on CONFIG_CHELSIO_T4. Hence it doesn't
make much sense to bother the user with the guard symbol question when
CONFIG_CHELSIO_T4 is disabled.
Fix this by moving the dependency from the individual config options to
the guard symbol.

Convert mvpp2 to split PCS support
This series converts the mvpp2 driver to use the split PCS support
that has been merged into phylink last time around. I've been running
this for some time here and, apart from the recent bug fix sent to
net-next, have not seen any issues on DT based systems. I have not
tested ACPI setups, although I've tried to preserve the workaround.
Patch 1 formalises the ACPI workaround.
Patch 2 moves some of mac_config() to the mac_prepare() and
mac_finish() callbacks so we can keep the ordering when we split
the PCS bits out.
Patch 3 ensures that the port is forced down while changing the
interface mode - when in in-band mode, doing this in mac_prepare()
and mac_finish().
Patch 4 moves the reset handling to mac_prepare() and mac_finish()
Patch 5 does a straight conversion to use PCS operations.
Patch 6 splits the PCS operations into a GMAC PCS operations and
XLG PCS operations, selecting the appropriate set during
mac_prepare(). This eliminates a bunch of conditionals from the
code.

l2tp: miscellaneous cleanups
This series of patches makes the following cleanups and improvements to
the l2tp code:
* various API tweaks to remove unused parameters from function calls
* lightly refactor the l2tp transmission path to capture more error
conditions in the data plane statistics
* repurpose the "magic feather" validation in l2tp to check for
sk_user_data (ab)use as opposed to refcount debugging
* remove some duplicated code

l2tp_tunnel_closeall is called as a part of tunnel shutdown in order to
close all the sessions held by the tunnel. The code it uses to close a
session duplicates what l2tp_session_delete does.
Rather than duplicating the code, have l2tp_tunnel_closeall call
l2tp_session_delete instead.
This involves a very minor change to locking in l2tp_tunnel_closeall.
Previously, l2tp_tunnel_closeall checked the session "dead" flag while
holding tunnel->hlist_lock. This allowed for the code to step to the
next session in the list without releasing the lock if the current
session happened to be in the process of closing already.
By calling l2tp_session_delete instead, l2tp_tunnel_closeall must now
drop and regain the hlist lock for each session in the tunnel list.
Given that the likelihood of a session being in the process of closing
when the tunnel is closed, it seems worth this very minor potential
loss of efficiency to avoid duplication of the session delete code.

The l2tp tunnel and session structures contain a "magic feather" field
which was originally intended to help trace lifetime bugs in the code.
Since the introduction of the shared kernel refcount code in refcount.h,
and l2tp's porting to those APIs, we are covered by the refcount code's
checks and warnings. Duplicating those checks in the l2tp code isn't
useful.
However, magic feather checks are still useful to help to detect bugs
stemming from misuse/trampling of the sk_user_data pointer in struct
sock. The l2tp code makes extensive use of sk_user_data to stash
pointers to the tunnel and session structures, and if another subsystem
overwrites sk_user_data it's important to detect this.
As such, rework l2tp's magic feather checks to focus on validating the
tunnel and session data structures when they're extracted from
sk_user_data.
* Add a new accessor function l2tp_sk_to_tunnel which contains a magic
feather check, and is used by l2tp_core and l2tp_ip[6]
* Comment l2tp_udp_encap_recv which doesn't use this new accessor function
because of the specific nature of the codepath it is called in
* Drop l2tp_session_queue_purge's check on the session magic feather:
it is called from code which is walking the tunnel session list, and
hence doesn't need validation
* Drop l2tp_session_free's check on the tunnel magic feather: the
intention of this check is covered by refcount.h's reference count
sanity checking
* Add session magic validation in pppol2tp_ioctl. On failure return
-EBADF, which mirrors the approach in pppol2tp_[sg]etsockopt.

l2tp_xmit_skb has a number of failure paths which are not reflected in
the tunnel and session statistics because the stats are updated by
l2tp_xmit_core. Hence any errors occurring before l2tp_xmit_core is
called are missed from the statistics.
Refactor the transmit path slightly to capture all error paths.
l2tp_xmit_skb now leaves all the actual work of transmission to
l2tp_xmit_core, and updates the statistics based on l2tp_xmit_core's

If tg3_reset_task() fails, the device state is left in an inconsistent
state with IFF_RUNNING still set but NAPI state not enabled. A
subsequent operation, such as ifdown or AER error can cause it to
soft lock up when it tries to disable NAPI state.
Fix it by bringing down the device to !IFF_RUNNING state when
tg3_reset_task() fails. tg3_reset_task() running from workqueue
will now call tg3_close() when the reset fails. We need to
modify tg3_reset_task_cancel() slightly to avoid tg3_close()
calling cancel_work_sync() to cancel tg3_reset_task(). Otherwise
cancel_work_sync() will wait forever for tg3_reset_task() to

There've been quite a few regression reports about the lowered volume
(reduced to ca 65% from the previous level) on Lenovo Thinkpad X1
after the commit d2cd795c4e ("ALSA: hda - fixup for the bass speaker
on Lenovo Carbon X1 7th gen"). Although the commit itself does the
right thing from HD-audio POV in order to have a volume control for
bass speakers, it seems that the machine has some secret recipe under
the hood.
Through experiments, Benjamin Poirier found out that the following
routing gives the best result:
* DAC1 (NID 0x02) -> Speaker pin (NID 0x14)
* DAC2 (NID 0x03) -> Shared by both Bass Speaker pin (NID 0x17) &
Headphone pin (0x21)
* DAC3 (NID 0x06) -> Unused
DAC1 seems to have some equalizer internally applied, and you'd get
again the output in a bad quality if you connect this to the
headphone pin. Hence the headphone is connected to DAC2, which is now
shared with the bass speaker pin. DAC3 has no volume amp, hence it's
not connected at all.
For achieving the routing above, this patch introduced a couple of
workarounds:
* The connection list of bass speaker pin (NID 0x17) is reduced not to
include DAC3 (NID 0x06)
* Pass preferred_pairs array to specify the fixed connection
Here, both workarounds are needed because the generic parser prefers
the individual DAC assignment over others.
When the routing above is applied, the generic parser creates the two
volume controls "Front" and "Bass Speaker". Since we have only two
DACs for three output pins, those are not fully controlling each
output individually, and it would confuse PulseAudio. For avoiding
the pitfall, in this patch, we rename those volume controls to some
unique ones ("DAC1" and "DAC2"). Then PulseAudio ignore them and
concentrate only on the still good-working "Master" volume control.
If a user still wants to control each DAC volume, they can still
change manually via "DAC1" and "DAC2" volume controls.

On RM400(a20r) machines ISA and SCSI interrupts share the same interrupt
line. Commit 49e6e07e3c ("MIPS: pass non-NULL dev_id on shared
request_irq()") accidently dropped the IRQF_SHARED bit, which breaks
registering SCSI interrupt. Put back IRQF_SHARED and add dev_id for
ISA interrupt.

In cc97ab235f ("MIPS: Simplify FP context initialization), init_fp_ctx
just initialize the fp/msa context, and own_fp_inatomic just restore
FCSR and 64bit FP regs from it, but miss MSACSR and upper MSA regs for
MSA, so MSACSR and MSA upper regs's value from previous task on current
cpu can leak into current task and cause unpredictable behavior when MSA
context not initialized.

SYSFW ABI 3.0 has changed the rchan_oes_offset value for am654 to support
SR2.
Since the kernel now needs SYSFW API 3.0 to work because the merged irqchip
update, we need to also update the am654 rchan_oes_offset.

Looks like when we converted everything over to Nvidia's class headers,
we mistakenly included the nvif/push507b.h instead of nvif/pushc37b.h,
which resulted in breaking CRC reporting for volta+:

Commit 2e26ccb119 ("drm/radeon: prefer lower reference dividers")
fixed screen flicker for HP Compaq nx9420 but breaks other laptops like
Asus X50SL.
Turns out we also need to favor lower feedback dividers.
Users confirmed this change fixes the regression and doesn't regress the
original fix.

On my R9 390, the voltage was reported as a constant 1000 mV.
This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor()
function, where some magic constants were used in a condition,
to determine whether the voltage should be read from PLANE2_VID
or PLANE1_VID. The VDDC mask was incorrectly used, instead of
the VDDGFX mask.
This patch changes the code to use the correct defined constants
(and apply the correct bitshift), thus resulting in correct voltage reporting.

Starting in Linux 5.8, the graphics and memory clock frequency were not being
reported for CIK cards. This is a regression, since they were reported correctly
in Linux 5.7.
After investigation, I discovered that the smum_send_msg_to_smc() function,
attempts to call the corresponding get_argument() function of ci_smu_funcs.
However, the get_argument() function is not defined in ci_smu_funcs.
This patch fixes the bug by specifying the correct get_argument() function.

Normally softwareshutdowntemp should be greater than Thotspotlimit.
However, on some VEGA10 ASIC, the softwareshutdowntemp is 91C while
Thotspotlimit is 105C. This seems not right and may trigger some
