At some point with all the GPIO clean-up we've broken the
MPUIO interrupts. Those are just a little bit different from
the GPIO interrupts, so we can fix it up just by setting
different irqchip functions for it. And then we can just
remove all old code trying to do the same.

But since RPMB partition is special and can not be accessed

If a P2P GO was allowed on a channel because of the GO concurrent
relaxation, i.e., another station interface was associated to an AP on
the same channel or the same UNII band, and the station interface
disconnected from the AP, allow the following use cases unless the
channel is marked as indoor only and the device is not operating in an
indoor environment:
1. Allow the P2P GO to stay on its current channel. The rationale behind
this is that if the channel or UNII band were allowed by the AP they
could still be used to continue the P2P GO operation, and avoid connection
breakage.
2. Allow another P2P GO to start on the same channel or another channel
that is in the same UNII band as the previous instantiated P2P GO.

f9fd54f22e ("mmc: sh_mmcif: Use msecs_to_jiffies() for host->timeout")
changed the timeout value from 1000 jiffies to 1s. In the case where
HZ is 1000 the values are the same. However, for smaller HZ values the
timeout is now smaller, 1s instead of 10s in the case of HZ=100.
Since the timeout occurs in spite of a normal data transfer a timeout of
10s seems more appropriate. This restores the previous timeout in the
case where HZ=100 and results in an increase over the previous timeout
for larger values of HZ.

f893959b08 ("x86/fpu: Don't abuse drop_init_fpu() in flush_thread()")
removed drop_init_fpu() usage from flush_thread(). This seems to break
things for me - the Go 1.4 test suite fails all over the place with
floating point comparision errors (offending commit found through
bisection).
The functional change was that flush_thread() after this commit
only calls restore_init_xstate() when both use_eager_fpu() and
!used_math() are true. drop_init_fpu() (now fpu_reset_state()) calls
restore_init_xstate() regardless of whether current used_math() - apply
the same logic here.
Switch used_math() -> tsk_used_math(tsk) to consistently use the grabbed
tsk instead of current, like in the rest of flush_thread().

In our department we are using some older Janz ICAN3-modules in our dekstop
pcs. There we have slightly different carrier boards than the janz-cmodio
supported in the kernel sources, called CAN-PCI2 with two submodules. But the
pci configuration regions are identical. So extending the supported pci devices
to the corresponding device ids is sufficient to get the drivers working.
* The old ICAN3-modules with firmware 1.28 need more then 250ms for the restart
after reset. I've increased the timeout to 500ms.
* The janz_ican3 module uses the raw can services of the Janz-firmware, this
means firmware must be ICANOS/2. Our ICAN3-modules are equipped with
CAL/CANopen-firmware, so I must use the appropriate commands for the layer
management services.
Te driver detects the firmware after module reset and selects the commands
matching the firmware. This affects the bus on/off-command
(ican3_set_bus_state) and the configuration of the bittiming
(ican3_set_bittiming). For better diagnostics the detected firmware string is
presented as sysfs attribute (fwinfo).

While setting the time, the RTC TIME register should not be accessed.
However due to hardware constraints, setting the RTC time involves
sleeping during 100ms. This sleep was done outside the critical section
protected by the spinlock, so it was possible to read the RTC TIME
register and get an incorrect value. This patch introduces a mutex for
protecting the RTC TIME access, unlike the spinlock it is allowed to
sleep in a critical section protected by a mutex.
The RTC STATUS register can still be used from the interrupt handler but
it has no effect on setting the time.

The range check for b-tree level parameter in nilfs_btree_root_broken()
is wrong; it accepts the case of "level == NILFS_BTREE_LEVEL_MAX" even
though the level is limited to values in the range of 0 to
(NILFS_BTREE_LEVEL_MAX - 1).
Since the level parameter is read from storage device and used to index
nilfs_btree_path array whose element count is NILFS_BTREE_LEVEL_MAX, it
can cause memory overrun during btree operations if the boundary value
is set to the level parameter on device.
This fixes the broken sanity check and adds a comment to clarify that

The documentation shows a need for gcc > 4.9.2, but it's really >=. The
Kconfig entries don't show require versions so add them. Correct a
latter/later typo too. Also mention that gcc 5 required to catch out of
bounds accesses to global and stack variables.

Currently memory_failure() calls shake_page() to sweep pages out from
pcplists only when the victim page is 4kB LRU page or thp head page.
But we should do this for a thp tail page too.
Consider that a memory error hits a thp tail page whose head page is on
a pcplist when memory_failure() runs. Then, the current kernel skips
shake_pages() part, so hwpoison_user_mappings() returns without calling
split_huge_page() nor try_to_unmap() because PageLRU of the thp head is
still cleared due to the skip of shake_page().
As a result, me_huge_page() runs for the thp, which is broken behavior.
One effect is a leak of the thp. And another is to fail to isolate the
memory error, so later access to the error address causes another MCE,
which kills the processes which used the thp.
This patch fixes this problem by calling shake_page() for thp tail case.
Fixes: 385de35722 ("thp: allow a hwpoisoned head page to be put back to LRU")

The file lib/find_last_bit.c was no longer used and supposed to be
deleted by commit 8f6f19dd51 ("lib: move find_last_bit to
lib/find_next_bit.c") but that delete didn't happen. This gets rid of
it.

The Firmware uses dynamic EQs allocation based on number of VFs and
max EQs that can be allocated. As a result, VF can have EQ numbers
that are larger than 256.
According to the firmware spec, the max value is limited to be 1024
(10 bits), adapt the relevant code accordingly. This bug was impossible
to hit prior to commit 7ae0e400cd ("net/mlx4_core: Flexible (asymmetric)
allocation of EQs and MSI-X vectors for PF/VFs") which actually enables
large number of EQs for VFs.
