This patch adds a new tracepoint to gather specific name information
of the superblock types.
This tracepoint can be used in conjunction with mm_shrink_slab_start and
mm_shrink_slab_end to get information like latency, number of
objects scanned by that particular shrinker, etc. The shrinker struct

Use IS_ALIGNED instead of opencoding to check the unaligned
case. And size is aligned to ZRAM_LOGICAL_BLOCK_SIZE which
will not make end <= start, so we do not need to compare
the start and end.

Currently, devices attached via a UART are not well supported in the
kernel. The problem is the device support is done in tty line disciplines,
various platform drivers to handle some sideband, and in userspace with
utilities such as hciattach.
There have been several attempts to improve support,
The UART bus is designed for slave devices such as Bluetooth, WiFi, GPS
and NFC connected to UARTs on host processors. Tradionally these have
been handled with tty line disciplines, rfkill, and userspace glue such
as hci_attach. This approach has many drawbacks since it doesn't fit
into the Linux d

Hi Michael,
Could you help to review this version when you have time?
Thanks!

Hi,
A few months ago, Chris Arges reported a bug involving alternatives/paravirt
patching that was discussed here [1] and here [2]. To briefly summarize the
bug, patch modules that contained .altinstructions or .parainstructions
sections would break because these alternative/paravirt patches would
Implement arch_klp_init_object_loaded() for x86, which applies
alternatives/paravirt patches. This fixes the order in which relocations
and alternatives/paravirt patches are applied.
Previously, if a patch module had alternatives or paravirt patches,
these were applied first by the module loader b
Introduce arch_klp_init_object_loaded() to complete any additional
arch-specific tasks during patching. Architecture code may override this
function.

The image converter kernel API supports conversion contexts and
job queues, so we should allow more than one handle to the IC, so
that multiple users can add jobs to the queue.
Note however that users that control the IC manually (that do not
use the image converter APIs but setup the IC task by h
This patch implements complete image conversion support to ipu-ic,
with tiling to support scaling to and from images up to 4096x4096.
Image rotation is also supported.
The internal API is subsystem agnostic (no V4L2 dependency except
for the use of V4L2 fourcc pixel formats).

v4:
- pruned included headers.
v3:
- renamed and exported ipu_vdi_set_top_field_man() to
ipu_vdi_set_field_order(). Args include std and field to determine
correct field order.
- exported ipu_vdi_set_motion().

Adds functions to link and unlink source channels to sink
channels in the FSU:
int ipu_fsu_link(struct ipu_soc *ipu, int src_ch, int sink_ch);
int ipu_fsu_unlink(struct ipu_soc *ipu, int src_ch, int sink_ch);
The channels numbers are usually IDMAC channels, but they can also be

In this version:
- rebased against latest drm-next.
- cleaned up header includes in ipu-vdi.c.
- do away with struct ipu_ic_tile_off in ipu-ic.c, and move tile offsets
into struct ipu_ic_tile. This paves the way for possibly allowing for
each tile to have different dimensions in the future.
Hi Guenter,
How about changing the property name for SuperSpeed as following?
It is more simple and reduce the length of property name.
- EXTCON_PROP_USB_SUPERSPEED -> EXTCON_PROP_USB_SS

1) Buffers powersave frame test is reversed in cfg80211, fix from
Felix Fietkau.
2) Remove bogus WARN_ON in openvswitch, from Jarno Rajahalme.
3) Fix some tg3 ethtool logic bugs, and one that would cause no
interrupts to be generated when rx-coalescing is set to 0.
