commit 8a092e682f20f193f2070dba2ea1904e95814126 upstream.
Bypass support was added in commit d38018f2019c ("regulator: anatop: Add
bypass support to digital LDOs"). A check for valid voltage selectors was
added in commit da0607c8df5c ("regulator: anatop: Fail on invalid voltage
selector") but it also discards all regulators that are in bypass mode. Add
check for the bypass setting. Errors below were seen on a Variscite mx6
board.
anatop_regulator 20c8000.anatop:regulator-vddcore@140: Failed to read a valid default voltage selector.
anatop_regulator: probe of 20c8000.anatop:regulator-vddcore@140 failed with error -22

commit e43e94c1eda76dabd686ddf6f7825f54d747b310 upstream.
Currently, the userspace governor only updates frequency on GOV_LIMITS
if policy->cur falls outside policy->{min/max}. However, it is also
necessary to update current frequency on GOV_LIMITS to match the user
requested value if it can be achieved within the new policy->{max/min}.
This was previously the behaviour in the governor until commit d1922f0
("cpufreq: Simplify userspace governor") which incorrectly assumed that
policy->cur == user requested frequency via scaling_setspeed. This won't
be true if the user requested frequency falls outside policy->{min/max}.
Ex: a temporary thermal cap throttled the user requested frequency.
Fix this by storing the user requested frequency in a seperate variable.
The governor will then try to achieve this request on every GOV_LIMITS
change.
Fixes: d1922f02562f (cpufreq: Simplify userspace governor)

commit 8b18e2359aff2ab810aba84cebffc9da07fef78f upstream.
For algorithms that implement IV generators before the crypto ops,
the IV needed for decryption is initially located in req->src
scatterlist, not in req->iv.
Avoid copying the IV into req->iv by modifying the (givdecrypt)
descriptors to load it directly from req->src.
aead_givdecrypt() is no longer needed and goes away.

commit a77ec83a57890240c546df00ca5df1cdeedb1cc3 upstream.
The address of the iovec &vq->iov[out] is not guaranteed to contain the scsi
command's response iovec throughout the lifetime of the command. Rather, it
is more likely to contain an iovec from an immediately following command
after looping back around to vhost_get_vq_desc(). Pass along the iovec
entirely instead.

The fifo code in upstream bcache can't use the last element in the buffer,
which was the cause of the bug: if you asked for a power of two size,
it'd give you a fifo that could hold one less than what you asked for
rather than allocating a buffer twice as big.

commit 532c34b5fbf1687df63b3fcd5b2846312ac943c6 upstream.
The sclp_ctl_ioctl_sccb function uses two copy_from_user calls to
retrieve the sclp request from user space. The first copy_from_user
fetches the length of the request which is stored in the first two
bytes of the request. The second copy_from_user gets the complete
sclp request, but this copies the length field a second time.
A malicious user may have changed the length in the meantime.

in single-threaded code and never modified after it is
created, and thus needs no locking. This patch introduces
a semaphore for tree access, as other patches in this

[ Upstream commit ea76543127da32dec28af0a13ea1b06625fc085e ]
While profiling the cxlflash_queuecommand() path under a heavy load it
was found that number of retries to find cmd_room was fairly high.
There are two problems with the current back-off:
a) It starts with a udelay of 0
b) It backs-off linearly
Tried several approaches (a higher multiple 10*n, 100*n, as well as n^2,
2^n) and found that the exponential back-off(2^n) approach had the least
overall cost. Cost as being defined as overall time spent waiting.
The fix is to change the linear back-off to an exponential back-off.
This solution also takes care of the problem with the initial
delay (starts with 1 usec).

[ Upstream commit d5e26bb1d812ba74f29b6bcbc88c3dbfb3eed824 ]
Applications which use virtual LUN's that are backed by a physical LUN
over both adapter ports may experience an I/O failure in the event of a
link loss (e.g. cable pull).
Virtual LUNs may be accessed through one or both ports of the adapter.
This access is encoded in the translation entries that comprise the
virtual LUN and used by the AFU for load-balancing I/O and handling
failover scenarios. In a link loss scenario, even though the AFU is able
to maintain connectivity to the LUN, it is up to the application to
retry the failed I/O. When applications are unaware of the virtual LUN's
underlying topology, they are unable to make a sound decision of when to
retry an I/O and therefore are forced to make their reaction to a failed
I/O absolute. The result is either a failure to retry I/O or increased
latency for scenarios where a retry is pointless.
To remedy this scenario, provide feedback back to the application on
virtual LUN creation as to which ports the LUN may be accessed. LUN's
spanning both ports are candidates for a retry in a presence of an I/O
failure.

[ Upstream commit 22f35042593c2b369861f0b9740efb8065a42db0 ]
Apparently some CHV boards failed to hook up the port presence straps
for HDMI ports as well (earlier we assumed this problem only affected
eDP ports). So let's check the VBT in addition to the strap, and if
either one claims that the port is present go ahead and register the
relevant connector.
While at it, change port D to register DP before HDMI as we do for ports
B and C since
commit 457c52d87e5d ("drm/i915: Only ignore eDP ports that are connected")
Also print a debug message when we register a HDMI connector to aid
in diagnosing missing/incorrect ports. We already had such a print for
DP/eDP.
v2: Improve the comment in the code a bit, note the port D change in
the commit message

If the VBT says that a certain port should be eDP (and hence fused off
from HDMI), but in reality it isn't, we need to try and acquire the HDMI
connection instead. So only trust the VBT edp setting if we can connect
to an eDP device on that port.

[ Upstream commit 3f4c68cfde30caa1f6d8368fd19590671411ade2 ]
Check for SMU RX local/remote faults along with SPU LINK
status. Otherwise at times link is UP at our end but DOWN
at link partner's side. Also due to an issue in BGX it's
rarely seen that initialization doesn't happen properly
and SMU RX reports faults with everything fine at SPU.
This patch tries to reinitialize LMAC to fix it.
Also fixed LMAC disable sequence to properly bring down link.

The hang is because of a 3 way dead-lock:
Process A holds the recovery mutex, and waits for eehd to complete.
Process B holds the semaphore and waits for the recovery mutex.
eehd waits for semaphore.
The fix is to have Process B above release the semaphore before
attempting to acquire the recovery mutex. This will allow
eehd to proceed to completion.

[ Upstream commit 603ecce95f4817074a724a889cd88c3c8210f933 ]
When switching to the internal LUN defined on the
IBM CXL flash adapter, there is an unnecessary
scan occurring on the second port. This scan leads
to the following extra lines in the log:
Dec 17 10:09:00 tul83p1 kernel: [ 3708.561134] cxlflash 0008:00:00.0: cxlflash_queuecommand: (scp=c0000000fc1f0f00) 11/1/0/0 cdb=(A0000000-00000000-10000000-00000000)
Dec 17 10:09:00 tul83p1 kernel: [ 3708.561147] process_cmd_err: cmd failed afu_rc=32 scsi_rc=0 fc_rc=0 afu_extra=0xE, scsi_extra=0x0, fc_extra=0x0
By definition, both of the internal LUNs are on the first port/channel.
When the lun_mode is switched to internal LUN the
same value for host->max_channel is retained. This
causes an unnecessary scan over the second port/channel.
This fix alters the host->max_channel to 0 (1 port), if internal
LUNs are configured and switches it back to 1 (2 ports) while
going back to external LUNs.

vmbus_initiate_unload()
[ Upstream commit 415719160de3fae3bb9cbc617664649919cd00d0 ]
We have to call vmbus_initiate_unload() on crash to make kdump work but
the crash can also be happening in interrupt (e.g. Sysrq + c results in
such) where we can't schedule or the following will happen:
[ 314.905786] bad: scheduling from the idle thread!
Just skipping the wait (and even adding some random wait here) won't help:
to make host-side magic working we're supposed to receive CHANNELMSG_UNLOAD
(and actually confirm the fact that we received it) but we can't use
interrupt-base path (vmbus_isr()-> vmbus_on_msg_dpc()). Implement a simple
busy wait ignoring all the other messages and use it if we're in an
interrupt context.

Looks like g4x hpd live status bits actually agree with the spec. At
least they do on the machine I have, and apparently on Nick Bowler's
g4x as well.
So gm45 may be the only platform where they don't agree. At least
that seems to be the case based on the (somewhat incomplete)
logs/dumps in [1], and Daniel has also tested this on his gm45
sometime in the past.
So let's change the bits to match the spec on g4x. That actually makes
the g4x bits identical to vlv/chv so we can just share the code
between those platforms, leaving gm45 as the special case.
