c265a3a669 net: mac802154: Explain the use of ieee802154_wake/stop_queue()
It is not straightforward to the newcomer that a single skb can
currently be sent at a time and that the internal process is to stop the
queue when processing a frame before re-enabling it.

Make this clear by documenting the ieee802154_wake/stop_queue()
helpers.

There is no point in accepting frames with a wrong or missing checksum,
at least not outside of a promiscuous setting. Set the right flag by

c705c87110 arm64: dts: renesas: ulcb-kf: Add 9-asix sensor device
This adds nodes for the lsm9ds0 sensor installed on the KF board.

With this patch, the sensor data becomes available over the IIO sysfs
interface.

The interrupt definition is not added yet, because the interrupt lines
of lsm9ds0 are pulled to VCC on the board, which implies a need for
active-low configuration. But the st_sensors drivers currently can't
work with active-low interrupts on this chip.

[1274934.746891] Kernel panic - not syncing: Bad Address (null pointer deref?)

The bug is caused by overrunning the sglist and incorrectly testing
sg_dma_len(sglist) before nents. Normally this doesn't cause a crash,
but in this case sglist crossed a page boundary. This occurs in the
following code:

	while (sg_dma_len(sglist) && nents--) {

The fix is simply to test nents first and move the decrement of nents
into the loop.

9129886b88 parisc: Drop __init from map_pages declaration
With huge kernel pages, we randomly eat a SPARC in map_pages(). This
is fixed by dropping __init from the declaration.

However, map_pages references the __init routine memblock_alloc_try_nid
via memblock_alloc.  Thus, it needs to be marked with __ref.

memblock_alloc is only called before the kernel text is set to readonly.

The __ref on free_initmem is no longer needed.

Comment regarding map_pages being in the init section is removed.

Split the drrs code that actually changes the refresh rate
(via PIPECONF or M/N values) to small helper functions that
only deal with the hardware details an nothing else. We'll

Use REG_GENMASK() & co. for the M/N register values. There are
also a lot of weird unused defines (eg. *_OFFSET) we can just

Also let's mask out the unused bits during readout for good

of the registers, which was a bit too inconsistent for my
taste.

bc1922e5d3 drm/i915: Fix a race between vma / object destruction and unbinding
The vma destruction code was using an unlocked advisory check for
drm_mm_node_allocated() to avoid racing with eviction code unbinding
the vma.

This is very fragile and prohibits the dereference of non-refcounted
pointers of dying vmas after a call to __i915_vma_unbind(). It also
prohibits the dereference of vma->obj of refcounted pointers of
dying vmas after a call to __i915_vma_unbind(), since even if a
refcount is held on the vma, that won't guarantee that its backing
object doesn't get destroyed.

So introduce an unbind under the vm mutex at object destroy time,
removing all weak references of the vma and its object from the
object vma list and from the vm bound list.

[   11.200000] mxs-mmc 80010000.spi: Error applying setting, reverse things back

Fix it by removing the MX23_PAD_SSP1_DETECT pin from the hog group as it

With this change the rootfs can be mounted and the imx23-evk board can

Device tree nodes for RTC devices should be called "rtc", so fix up some

7e9102c9f9 ARM: dts: imx28: Use correct compatible string for RTC
The "mxim" vendor prefix does not exit, though it looks like it might
have been a typo'ed "maxim". Still, no compatible string exists that
matches "maxim,ds1339". The closest is the "dallas,ds1339" and since
this node is named "rtc" that's probably the one that was intended.

e7d786331c Merge branch 'udp-ipv6-optimisations'
Pavel Begunkov says:

====================
udp/ipv6 optimisations

Shed some weight from udp/ipv6. Zerocopy benchmarks over dummy showed
~5% tx/s improvement, should be similar for small payload non-zc
cases.

The performance comes from killing 4 atomics and a couple of big struct
memcpy/memset. 1/10 removes a pair of atomics on dst refcounting for
cork->skb setup, 9/10 saves another pair on cork init. 5/10 and 8/10
kill extra 88B memset and memcpy respectively.
