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+:
nouveau 0000:1f:00.0: disp: chid 0 stat 10003361 reason 3
[RESERVED_METHOD] mthd 0d84 data 00000000 code 00000000

Commit 2e26ccb119bd ("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.

tpg->np_login_sem
The iSCSI target login thread might get stuck with the following stack:
cat /proc/`pidof iscsi_np`/stack
[<0>] down_interruptible+0x42/0x50
[<0>] iscsit_access_np+0xe3/0x167
[<0>] iscsi_target_locate_portal+0x695/0x8ac
[<0>] __iscsi_target_login_thread+0x855/0xb82
[<0>] iscsi_target_login_thread+0x2f/0x5a
[<0>] kthread+0xfa/0x130
[<0>] ret_from_fork+0x1f/0x30
This can be reproduced via the following steps:
1. Initiator A tries to log in to iqn1-tpg1 on port 3260. After finishing
PDU exchange in the login thread and before the negotiation is finished
the the network link goes down. At this point A has not finished login
and tpg->np_login_sem is held.
2. Initiator B tries to log in to iqn2-tpg1 on port 3260. After finishing
PDU exchange in the login thread the target expects to process remaining
login PDUs in workqueue context.
3. Initiator A' tries to log in to iqn1-tpg1 on port 3260 from a new
socket. A' will wait for tpg->np_login_sem with np->np_login_timer
loaded to wait for at most 15 seconds. The lock is held by A so A'
eventually times out.
4. Before A' got timeout initiator B gets negotiation failed and calls
iscsi_target_login_drop()->iscsi_target_login_sess_out(). The
np->np_login_timer is canceled and initiator A' will hang forever.
Because A' is now in the login thread, no new login requests can be
serviced.
Fix this by moving iscsi_stop_login_thread_timer() out of
iscsi_target_login_sess_out(). Also remove iscsi_np parameter from
iscsi_target_login_sess_out().

Change the default value of hard_header_len in hdlc.c from 16 to 0.
Currently there are 6 HDLC protocol drivers, among them:
hdlc_raw_eth, hdlc_cisco, hdlc_ppp, hdlc_x25 set hard_header_len when
attaching the protocol, overriding the default. So this patch does not
affect them.
hdlc_raw and hdlc_fr don't set hard_header_len when attaching the
protocol. So this patch will change the hard_header_len of the HDLC
device for them from 16 to 0.
This is the correct change because both hdlc_raw and hdlc_fr don't have
header_ops, and the code in net/packet/af_packet.c expects the value of
hard_header_len to be consistent with header_ops.
In net/packet/af_packet.c, in the packet_snd function,
for AF_PACKET/DGRAM sockets it would reserve a headroom of
hard_header_len and call dev_hard_header to fill in that headroom,
and for AF_PACKET/RAW sockets, it does not reserve the headroom and
does not call dev_hard_header, but checks if the user has provided a
header of length hard_header_len (in function dev_validate_header).

We recently added some calls to clk_disable_unprepare() but we missed
the last error path if register_netdev() fails.
I made a couple cleanups so we avoid mistakes like this in the future.
First I reversed the "if (!ret)" condition and pulled the code in one
indent level. Also, the "port->netdev = NULL;" is not required because
"port" isn't used again outside this function so I deleted that line.

The "tx/rx-transfer - crossing PAGE_SIZE" test always fails when

with iteration values: len = 131071, tx_off = 0, rx_off = 3
with iteration values: len = 131071, tx_off = 0, rx_off = 4

actual_length: 131071
spi_transfer@ffffffd5a41576f8
len: 131071
tx_buf: ffffffd5a4340ffc
Note that rx_offset > 3 can only occur if the SPI controller driver sets
->dma_alignment to a higher value than 4, so most SPI controller drivers
are not affect.
The allocated Rx buffer is of size SPI_TEST_MAX_SIZE_PLUS, which is 132
KiB (assuming 4 KiB pages). This test uses an initial offset into the
rx_buf of PAGE_SIZE - 4, and a len of 131071, so the range expected to
be written in this transfer ends at (4096 - 4) + 5 + 131071 == 132 KiB,
which is also the end of the allocated buffer. But the code which
verifies the content of the buffer reads a byte beyond the allocated
buffer and spuriously fails because this out-of-bounds read doesn't
return the expected value.
Fix this by using ITERATE_LEN instead of ITERATE_MAX_LEN to avoid
testing sizes which cause out-of-bounds reads.

If the zero duty cycle doesn't correspond to any voltage in the voltage
table, the PWM regulator returns an -EINVAL from get_voltage_sel() which
results in the core erroring out with a "failed to get the current
voltage" and ending up not applying the machine constraints.
Instead, return -ENOTRECOVERABLE which makes the core set the voltage
since it's at an unknown value.
For example, with this device tree:
fooregulator {
compatible = "pwm-regulator";
pwms = <&foopwm 0 100000>;
regulator-min-microvolt = <2250000>;
regulator-max-microvolt = <2250000>;
regulator-name = "fooregulator";
regulator-always-on;
regulator-boot-on;
voltage-table = <2250000 30>;
};

All three generations of Sandisk SSDs lock up hard intermittently.
Experiments showed that disabling NCQ lowered the failure rate significantly
and the kernel has been disabling NCQ for some models of SD7's and 8's,
which is obviously undesirable.
Karthik worked with Sandisk to root cause the hard lockups to trim commands
larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which
limits max trim size to 128M and applies it to all three generations of
Sandisk SSDs.

This patch fixes a few bugs:
1- We weren't taking into account sha_leftovers when adding multiple
ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with
the beginning of ksv[j]
2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was
being placed on the wrong half of sha_text, overlapping the leftover
ksv value
3- In the sha_leftovers == 2 case, we need to manually terminate the
byte stream with 0x80 since the hardware doesn't have enough room to
add it after writing M0
The upside is that all of the HDCP supported HDMI repeaters I could
find on Amazon just strip HDCP anyways, so it turns out to be _really_
hard to hit any of these cases without an MST hub, which is not (yet)
supported. Oh, and the sha_leftovers == 1 case works perfectly!

since it means the first hunk of the patch this fixes won't actually do

It was discovered that sdparm will fail when attempting to disable write
cache on a SATA disk connected via libsas.
In the ATA command set the write cache state is controlled through the SET
FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and
the latter command is what is used in the SCSI-ATA translation layer. A
subtle difference is that a MODE SELECT carries data whereas SET FEATURES
is defined as a non-data command in ATA.
Set the DMA data direction to DMA_NONE if the requested ATA command is
identified as non-data.

The dm-integrity target did not report errors in bitmap mode just after
creation. The reason is that the function integrity_recalc didn't clean up
ic->recalc_bitmap as it proceeded with recalculation.
Fix this by updating the bitmap accordingly -- the double shift serves
to rounddown.

Commit 935fcc56abc3 ("dm mpath: only flush workqueue when needed")
changed flush_multipath_work() to avoid needless workqueue
flushing (of a multipath global workqueue). But that change didn't
realize the surrounding flush_multipath_work() code should also only
run if 'pg_init_in_progress' is set.
Fix this by only doing all of flush_multipath_work()'s PG init related
work if 'pg_init_in_progress' is set.
Otherwise multipath_wait_for_pg_init_completion() will run
unconditionally but the preceeding flush_workqueue(kmpath_handlerd)
may not. This could lead to deadlock (though only if kmpath_handlerd
never runs a corresponding work to decrement 'pg_init_in_progress').
It could also be, though highly unlikely, that the kmpath_handlerd
work that does PG init completes before 'pg_init_in_progress' is set,
and then an intervening DM table reload's multipath_postsuspend()
triggers flush_multipath_work().

The function dax_direct_access doesn't take partitions into account,
it always maps pages from the beginning of the device. Therefore,
persistent_memory_claim() must get the partition offset using
get_start_sect() and add it to the page offsets passed to
dax_direct_access().

On machines with much memory (> 2 TByte) and log_mtts_per_seg == 0, a
max_order of 31 will be passed to mlx_buddy_init(), which results in
s = BITS_TO_LONGS(1 << 31) becoming a negative value, leading to
kvmalloc_array() failure when it is converted to size_t.

This fixes the behavior of the scaling_max_freq and scaling_min_freq
sysfs files in systems which had turbo disabled by the BIOS.
Caleb noticed that the HWP is programmed to operate in the wrong
P-state range on his system when the CPUFREQ policy min/max frequency
is set via sysfs. This seems to be because in his system
intel_pstate_get_hwp_max() is returning the maximum turbo P-state even
though turbo was disabled by the BIOS, which causes intel_pstate to
scale kHz frequencies incorrectly e.g. setting the maximum turbo
frequency whenever the maximum guaranteed frequency is requested via
sysfs.

When intel_pstate switches the operation mode from "active" to
"passive" or the other way around, freeing its data structures
representing CPUs and allocating them again from scratch is not
necessary and wasteful. Moreover, if these data structures are
preserved, the cached HWP Request MSR value from there may be
written to the MSR to start with to reinitialize it and help to
restore the EPP value set previously (it is set to 0xFF when CPUs
go offline to allow their SMT siblings to use the full range of
EPP values and that also happens when the driver gets unregistered).
Accordingly, modify the driver to only do a full cleanup on driver
object registration errors and when its status is changed to "off"
via sysfs and to write the cached HWP Request MSR value back to
the MSR on CPU init if the data structure representing the given
CPU is still there.

Add ->offline and ->online driver callbacks to prepare for taking a
CPU offline and to restore its working configuration when it goes
back online, respectively, to avoid invoking the ->init callback on
every CPU online which is quite a bit of unnecessary overhead.
Define ->offline and ->online so that they can be used in the
passive mode as well as in the active mode and because ->offline
will do the majority of ->stop_cpu work, the passive mode does
not need that callback any more, so drop it from there.
Also modify the active mode ->suspend and ->resume callbacks to
prevent them from interfering with the new ->offline and ->online
ones in case the latter are invoked withing the system-wide suspend
and resume code flow and make the passive mode use them too.

Modify the EPP sysfs interface to reject attempts to change the EPP
to values different from 0 ("performance") in the active mode with
the "performance" policy (ie. scaling_governor set to "performance"),
to avoid situations in which the kernel appears to discard data
passed to it via the EPP sysfs attribute.

Make intel_pstate update the cached EPP value when setting the EPP
via sysfs in the active mode just like it is the case in the passive
mode, for consistency, but also for the benefit of subsequent
changes.
No intentional functional impact.

After commit f6ebbcf08f37 ("cpufreq: intel_pstate: Implement passive
mode with HWP enabled") it is possible to change the driver status
to "off" via sysfs with HWP enabled, which effectively causes the
driver to unregister itself, but HWP remains active and it forces the
minimum performance, so even if another cpufreq driver is loaded,
it will not be able to control the CPU frequency.
For this reason, make the driver refuse to change the status to
"off" with HWP enabled.
