commit ec6a75ef8e33fe33f963b916fd902c52a0be33ff upstream.
Previously, pci_pm_resume_noirq() cleared the PME Status bit in the Root
Status register only if the device had no driver or the driver did not
implement legacy power management. It should clear PME Status regardless
of what sort of power management the driver supports, so do this before
checking for legacy power management.
This affects Root Ports and Root Complex Event Collectors, for which the
usual driver is the PCIe portdrv, which implements new power management, so
this change is just on principle, not to fix any actual defects.

commit 1137e61dcb99f7f8b54e77ed83f68b5b485a3e34 upstream.
find_next_bit() takes a parameter of size long, and performs arithmetic

Therefore we cannot pass a u32, since this will cause find_next_bit()

commit 364b3f1ff8f096d45f042a9c85daf7a1fc78413e upstream.
Aardvark's PCI_EXP_LNKSTA_LT flag in its link status register is not
implemented and does not reflect the actual link training state (the
flag is always set to 0). In order to support link re-training feature
this flag has to be emulated. The Link Training and Status State
Machine (LTSSM) flag in Aardvark LMI config register could be used as
a link training indicator. Indeed if the LTSSM is in L0 or upper state
then link training has completed (see [1]).
Unfortunately because after asking a link retraining it takes a while
for the LTSSM state to become less than 0x10 (due to L0s to recovery
state transition delays), LTSSM can still be in L0 while link training
has not finished yet. So this waits for link to be in recovery or lesser
state before returning after asking for a link retrain.

commit 75fcc0ce72e5cea2e357cdde858216c5bad40442 upstream.
We try to keep PCIe hotplug ports runtime suspended when entering system
suspend. Because the PCIe portdrv sets the DPM_FLAG_NEVER_SKIP flag, the PM
core always calls system suspend/resume hooks even if the device is left
runtime suspended. Since PCIe hotplug driver re-used the same function for
both runtime suspend and system suspend, it ended up disabling hotplug
interrupt twice and the second time following was printed:
pciehp 0000:03:01.0:pcie204: pcie_do_write_cmd: no response from device
Prevent this from happening by checking whether the device is already
runtime suspended when the system suspend hook is called.

completely.
There's no reason to do the strdup in cases where the filesystem does

The geode AES driver is heavily broken because it stores per-request
state in the transform context. So it will crash or produce the wrong
result if used by any of the many places in the kernel that issue
concurrent requests for the same transform object.
This driver is also implemented using the deprecated blkcipher API,
which makes it difficult to fix, and puts it among the drivers
preventing that API from being removed.
Convert this driver to use the skcipher API, and change it to not store
per-request state in the transform context.

commit 5b0fe9552336338acb52756daf65dd7a4eeca73f upstream.
When algif_skcipher does a partial operation it always process data
that is a multiple of blocksize. However, for algorithms such as
CTR this is wrong because even though it can process any number of
bytes overall, the partial block must come at the very end and not
in the middle.
This is exactly what chunksize is meant to describe so this patch
changes blocksize to chunksize.

In order to allow for CBC to be chained, which is something that the
CTS template relies upon, implementations of CBC need to pass the
IV to be used for subsequent invocations via the IV buffer. This was
not implemented yet for virtio-crypto so implement it now.

The proximal cause is that this rpcrdma_rep has a rr_rdmabuf that
is still pointing to the old ib_device, which has been freed. The
only way that is possible is if this rpcrdma_rep was not destroyed
by rpcrdma_ia_remove.
Debugging showed that was indeed the case: this rpcrdma_rep was
still in use by a completing RPC at the time of the device removal,
and thus wasn't on the rep free list. So, it was not found by
rpcrdma_reps_destroy().
The fix is to introduce a list of all rpcrdma_reps so that they all
can be found when a device is removed. That list is used to perform
only regbuf DMA unmapping, replacing that call to
rpcrdma_reps_destroy().
Meanwhile, to prevent corruption of this list, I've moved the
destruction of temp rpcrdma_rep objects to rpcrdma_post_recvs().
rpcrdma_xprt_drain() ensures that post_recvs (and thus rep_destroy) is
not invoked while rpcrdma_reps_unmap is walking rb_all_reps, thus
protecting the rb_all_reps list.

I've found that on occasion, "rmmod <dev>" will hang while if an NFS

Ensure that ri_remove_done is initialized only just before the
transport is woken up to force a close. This avoids the completion
possibly getting initialized again while the CM event handler is
waiting for a wake-up.

commit 6ae01050e49f0080ae30575d9b45a6d4a3d7ee23 upstream.
Use our default values when wrong module-parameters are given, instead of
refusing to load. Refusing to load leaves the fan at the BIOS default
setting, which is "Off". The CPU's thermal throttling should protect the
system from damage, but not-loading is really not the best fallback in this
case.
This commit fixes this by re-setting module-parameter values to their
defaults if they are out of range, instead of failing the probe with
-EINVAL.
