The RB532 platform specific irq_to_gpio() implementation has been
removed with commit 832f5dacfa0b ("MIPS: Remove all the uses of
custom gpio.h"). Now the platform uses the generic stub which causes
the following error:
pata-rb532-cf pata-rb532-cf: no GPIO found for irq149
pata-rb532-cf: probe of pata-rb532-cf failed with error -2
Drop the irq_to_gpio() call and get the GPIO number from platform
data instead. After this change, the driver works again:

actions could change the etherproto in particular with ethernet
tunnelled data. Typically such actions, after peeling the outer header,
will ask for the packet to be reclassified. We then need to restart
the classification with the new proto header.
Example setup used to catch this:
sudo tc qdisc add dev $ETH ingress
sudo $TC filter add dev $ETH parent ffff: pref 1 protocol 802.1Q \

The assumption when adding the intel_display_power_is_enabled() checks
was that if it returns success the power can't be turned off afterwards
during the HW access, which is guaranteed by modeset locks. This isn't
always true, so make sure we hold a dedicated reference for the time of
the access.

A non-atomic PCM stream may take snd_pcm_link_rwsem rw semaphore twice
in the same code path, e.g. one in snd_pcm_action_nonatomic() and
another in snd_pcm_stream_lock(). Usually this is OK, but when a
write lock is issued between these two read locks, the problem
happens: the write lock is blocked due to the first reade lock, and
the second read lock is also blocked by the write lock. This
eventually deadlocks.
The reason is the way rwsem manages waiters; it's queued like FIFO, so
even if the writer itself doesn't take the lock yet, it blocks all the
waiters (including reads) queued after it.
As a workaround, in this patch, we replace the standard down_write()
with an spinning loop. This is far from optimal, but it's good
enough, as the spinning time is supposed to be relatively short for
normal PCM operations, and the code paths requiring the write lock
aren't called so often.

A kernel page fault oops with the callstack below was observed
when a read syscall was made to a pmem device after a huge amount
(>512GB) of vmalloc ranges was allocated by ioremap() on a x86_64
system:

Since v4.1, ioremap() supports large page (pud/pmd) mappings in
x86_64 and PAE. vmalloc_fault() however assumes that the vmalloc
range is limited to pte mappings.
vmalloc faults do not normally happen in ioremap'd ranges since
ioremap() sets up the kernel page tables, which are shared by
user processes. pgd_ctor() sets the kernel's PGD entries to
user's during fork(). When allocation of the vmalloc ranges
crosses a 512GB boundary, ioremap() allocates a new pud table
and updates the kernel PGD entry to point it. If user process's
PGD entry does not have this update yet, a read/write syscall
to the range will cause a vmalloc fault, which hits the Oops
above as it does not handle a large page properly.
Following changes are made to vmalloc_fault().
64-bit:
- No change for the PGD sync operation as it handles large
pages already.
- Add pud_huge() and pmd_huge() to the validation code to
handle large pages.
- Change pud_page_vaddr() to pud_pfn() since an ioremap range
is not directly mapped (while the if-statement still works
with a bogus addr).
- Change pmd_page() to pmd_pfn() since an ioremap range is not
backed by struct page (while the if-statement still works
with a bogus addr).
32-bit:
- No change for the sync operation since the index3 PGD entry
covers the entire vmalloc range, which is always valid.
(A separate change to sync PGD entry is necessary if this
memory layout is changed regardless of the page size.)
- Add pmd_huge() to the validation code to handle large pages.
This is for completeness since vmalloc_fault() won't happen
in ioremap'd ranges as its PGD entry is always valid.

Since commit 113c74d83eef ("net: phy: turn carrier off on phy attach"),
this lead to the link not coming up at boot anymore, due to the phy
state machine being stuck at waiting for interrupts (off by default on
the 88E1510).
For seven other Marvell PHYs, marvell_of_reg_init was not called at all.
Add a generic marvell_config_init function, which in turn calls
marvell_of_reg_init.
PHYs, which already have a specific config_init function with a call to
marvell_of_reg_init, are left untouched. The generic marvell_config_init
function is called for all the others, to get consistent behavior across
all Marvell PHYs.

Remove the ftrace module notifier in favor of directly calling
ftrace_module_enable() and ftrace_release_mod() in the module loader.
Hard-coding the function calls directly in the module loader removes
dependence on the module notifier call chain and provides better
visibility and control over what gets called when, which is important
to kernel utilities such as livepatch.
This fixes a notifier ordering issue in which the ftrace module notifier
(and hence ftrace_module_enable()) for coming modules was being called
after klp_module_notify(), which caused livepatch modules to initialize
incorrectly. This patch removes dependence on the module notifier call
chain in favor of hard coding the corresponding function calls in the
module loader. This ensures that ftrace and livepatch code get called in
the correct order on patch module load and unload.

- Platform information. Vendor, model, id, pci id.
- Graphical environment: Gnome, KDE, openbox, etc...

- Also good if you could run PSR test cases of Intel-gpu-tools
- Please mention if forcing main link standby or main link off helps you.

- Platform information. Vendor, model, id, pci id.
- Graphical environment: Gnome, KDE, openbox, etc...
- Details how to reproduce.
- Also good if you could run PSR test cases of Intel-gpu-tools
- Please mention if forcing main link standby or main link off helps you.
There are Intel-gpu-tools test cases that can be helpful to
determine if PSR is working as expected:
kms_psr_sink_crc and kms_psr_frontbuffer_tracking.

This will give us flexibility to enable PSR by default independently so
issues and corner cases in one platform won't affect others were we have
it working properly.

The example in the DT binding documentation uses the preliminary DT
bindings for the r8a7795 MSTP clocks, which never went upstream.
Update the example to use the DT bindings for the upstream Clock Pulse
Generator / Module Standby and Software Reset hardware block.

When a VLAN device leaves a bridge its STP state is set to DISABLED,
which causes the hardware to discard any packets coming through the port
with this VLAN.
Fix that by setting STP state to FORWARDING when the device leaves its
bridge and allow traffic to be directed to CPU.

A previous commit (33f72e6) added notification via netlink for tunnels
when created/modified/deleted. If the notification returned an error,
this error was returned from the tunnel function. If there were no
listeners, the error code ESRCH was returned, even though having no
listeners is not an error. Other calls to this and other similar
notification functions either ignore the error code, or filter ESRCH.
This patch checks for ESRCH and does not flag this as an error.

Pull block fixes from Jens Axboe:
"A collection of fixes from the past few weeks that should go into 4.5.
This contains:
- Overflow fix for sysfs discard show function from Alan.
- A stacking limit init fix for max_dev_sectors, so we don't end up
artificially capping some use cases. From Keith.
- Have blk-mq proper end unstarted requests on a dying queue, instead
of pushing that to the driver. From Keith.
- NVMe:
- Update to Kconfig description for NVME_SCSI, since it was
vague and having it on is important for some SUSE distros.
From Christoph.
- Set of fixes from Keith, around surprise removal. Also kills
the no-merge flag, so it supports merging.
- Set of fixes for lightnvm from Matias, Javier, and Wenwei.
- Fix null_blk oops when asked for lightnvm, but not available. From
Matias.
- Copy-to-user EINTR fix from Hannes, fixing a case where SG_IO fails
if interrupted by a signal.
- Two floppy fixes from Jiri, fixing signal handling and blocking
open.
- A use-after-free fix for O_DIRECT, from Mike Krinkin.
- A block module ref count fix from Roman Pen.
- An fs IO wait accounting fix for O_DSYNC from Stephane Gasparini.
- Smaller reallo fix for xen-blkfront from Bob Liu.
- Removal of an unused struct member in the deadline IO scheduler,
from Tahsin.
- Also from Tahsin, properly initialize inode struct members
associated with cgroup writeback, if enabled.
- From Tejun, ensure that we keep the superblock pinned during cgroup
writeback"

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
"This includes two fixes.
The first is something that has come up a few times and has been
worked out individually, but it's come up now enough that the problem
should be generic. Tracepoints are protected by RCU sched. There are
several tracepoints within core infrastructure like kfree(). If a
tracepoint is called when the CPU is going down, or when it's coming
up but has yet to be recognized by RCU, a RCU warning is triggered.
This is a true bug as that tracepoint is not protected by RCU.
Usually, this is taken care of by testing for cpu online as a
tracepoint condition. But as this is happening more often, moving it
from a individual tracepoint to a check in the tracepoint
infrastructure is more robust.
Note, there is now a duplicate of a cpu online test, because this
update does not remove the individual checks. But the overhead is
small enough that the removal can be done in another release.
The second change is strange linker breakage due to the branch
tracer's builtin_constant_p() check failing, and treating the
condition as a variable instead of a constant. Arnd Bergmann found
that this can be fixed by testing !!(cond) instead of just (cond)"
* tag 'trace-fixes-v4.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing: Fix freak link error caused by branch tracer
tracepoints: Do not trace when cpu is offline
