b1cae1f84a s390: fix irq state tracing
With commit 58c644ba51 ("sched/idle: Fix arch_cpu_idle() vs
tracing") common code calls arch_cpu_idle() with a lockdep state that
tells irqs are on.

This doesn't work very well for s390: psw_idle() will enable interrupts
to wait for an interrupt. As soon as an interrupt occurs the interrupt
handler will verify if the old context was psw_idle(). If that is the
case the interrupt enablement bits in the old program status word will
be cleared.

A subsequent test in both the external as well as the io interrupt
handler checks if in the old context interrupts were enabled. Due to
the above patching of the old program status word it is assumed the
old context had interrupts disabled, and therefore a call to
TRACE_IRQS_OFF (aka trace_hardirqs_off_caller) is skipped. Which in
turn makes lockdep incorrectly "think" that interrupts are enabled
within the interrupt handler.

Fix this by unconditionally calling TRACE_IRQS_OFF when entering
interrupt handlers. Also call unconditionally TRACE_IRQS_ON when
leaving interrupts handlers.

This leaves the special psw_idle() case, which now returns with
interrupts disabled, but has an "irqs on" lockdep state. So callers of
psw_idle() must adjust the state on their own, if required. This is
currently only __udelay_disabled().

a2bd4097b3 s390/pci: fix CPU address in MSI for directed IRQ
The directed MSIs are delivered to CPUs whose address is
written to the MSI message address. The current code assumes
that a CPU logical number (as it is seen by the kernel)
is also the CPU address.

The above assumption is not correct, as the CPU address
is rather the value returned by STAP instruction. That
value does not necessarily match the kernel logical CPU
number.

Because of how for_each_bvec() works it never advances across multiple
entries at a time, so bvec_iter_advance() is an overkill. Add
specialised bvec_iter_advance_single() that is faster. It also handles
zero-len bvecs, so can kill bvec_iter_skip_zero_bvec().

The series supports new machines with rt1015p and rt5682.  Reuses most of
the code in mt8192-mt6359-rt1015-rt5682.c.

The first 3 patches refactor the existing mt8192-mt6359-rt1015-rt5682.c.
For easier to support newly added components later.

The 4th patch fixes a typo in DT bindings document.

The 5th patch proposes a new compatible string "mt8192_mt6359_rt1015p_rt5682"
for machines with rt1015p and rt5682.

The 6th patch reuses the existing machine driver to support machines with
rt1015p and rt5682.

1ed36ecd14 media: i2c: imx219: Selection compliance fixes
To comply with the intended usage of the V4L2 selection target when
used to retrieve a sensor image properties, adjust the rectangles
returned by the imx219 driver.

The top/left crop coordinates of the TGT_CROP rectangle were set to
(0, 0) instead of (8, 8) which is the offset from the larger physical
pixel array rectangle. This was also a mismatch with the default values
crop rectangle value, so this is corrected. Found with v4l2-compliance.

While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
CROP_BOUNDS have the same size as the non-active pixels are not readable
using the selection API. Found with v4l2-compliance.

[reword commit message, use macros for pixel offsets]

Currently pointer nvm is being dereferenced before it is being null
checked.  Fix this by moving the assignments of pointers client and
ov2740 so that are after the null check hence avoiding any potential
null pointer dereferences on pointer nvm.

0359af7ac3 SUNRPC: Remove XDRBUF_SPARSE_PAGES flag in gss_proxy upcall
There's no need to defer allocation of pages for the receive buffer.

- This upcall is quite infrequent
- gssp_alloc_receive_pages() can allocate the pages with GFP_KERNEL,
  unlike the transport
- gssp_alloc_receive_pages() knows exactly how many pages are needed

989bea4891 media: v4l: subdev: Set sd->devnode before registering the subdev
The subdev's video device node was only assigned after registering the
device node in the system. While it is unlikely that a driver needed to
use this field in handling system calls to its file handle, there remains
a slim chance the devnode field remains NULL while the driver expects to
find a video node there.

Assign the devnode field before registering the device, and assign it back
to NULL if the registration failed.

d0fbdcbe75 media: ccs: Request for "reset" GPIO
The DT bindings documented "reset-gpios" property but the driver never
made use of it. Instead it used a GPIO called "xshutdown", with apprently
wrong polarity.

Fix this by requesting "reset" GPIO with the right polarity first, and if
that fails, then request "xshutdown" GPIO with the old polarity. This way
it works for new users as expected while if someone, somewhere, depended
on "xshutdown" GPIO, that continues to work as well.
