platforms that support memory encryption, e.g.:
"Memory Encryption Features active:AMD SEV SEV-ES"
There is no space before "AMD" and two spaces after it. Fix this so that

In the SoC before, such as mt8173, it has 2 pipelines binding to one
mmsys with the same clock driver and the same power domain.
In mt8195, there are 4 pipelines binding to 4 different mmsys, such as
vdosys0, vdosys1, vppsys0 and vppsys1.
Each mmsys uses different clock drivers and different power domain.
Since each mmsys has its own mmio base address, they could be identified
by their different address during probe time.

Add driver for Lontium LT9211 Single/Dual-Link DSI/LVDS or Single DPI to
Single-link/Dual-Link DSI/LVDS or Single DPI bridge. This chip is highly
capable at converting formats, but sadly it is also highly undocumented.
This driver is written without any documentation from Lontium and based
only on shreds of information available in various obscure example codes,
hence long runs of unknown register patches and lengthy delays in various
places. Whichever register meaning could be divined from its behavior has
at least a comment around it.
Currently the only mode tested is Single-link DSI to Single-link LVDS.
Dual-link LVDS might work as well, the register programming is in place,
but is untested.

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and

and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

On a zoned filesystem, if we fail to allocate the root node for the log
root tree while syncing the log, we end up returning without finishing
the IO plug we started before, resulting in leaking resources as we
have started writeback for extent buffers of a log tree before. That
allocation failure, which typically is either -ENOMEM or -ENOSPC, is not
fatal and the fsync can safely fallback to a full transaction commit.
So release the IO plug if we fail to allocate the extent buffer for the
root of the log root tree when syncing the log on a zoned filesystem.

get some drm_WARN_ON(&dev_priv->drm, !(tmp & PSR2_MAN_TRK_CTL_ENABLE))

This is probably due psr2_sel_fetch_cff_enabled being left set during
PSR disable in the pipe A, so the PSR2_MAN_TRK_CTL write in
intel_psr2_program_trans_man_trk_ctl() is skipped in pipe B and then
we get the warning when actually enabling PSR after planes programing.
We don't get such warnings when running tests in pipe A because
PSR2_MAN_TRK_CTL is only cleared when enabling PSR2 with hardware
tracking.
Was not able to reproduce this issue but cleaning the PSR state
disable will not harm anything at all.

====================
rtnetlink: improve ALT_IFNAME config and fix dangerous GROUP usage
First commit forbids dangerous calls when both IFNAME and GROUP are
given, since it can introduce unexpected behaviour when IFNAME does not
match any interface.
Second patch achieves primary goal of this patchset to fix/improve
IFLA_ALT_IFNAME attribute, since previous code was never working for
newlink/setlink. ip-link command is probably getting interface index
before, and was not using this feature.
Last two patches are improving error code on corner cases.
Changes in v2:
* Remove ifname argument in rtnl_dev_get/do_setlink
functions (simplify code)
* Use a boolean to avoid condition duplication in __rtnl_newlink
Changes in v3:
* Simplify rtnl_dev_get signature
Changes in v4:
* Rename link_lookup to link_specified
Changes in v5:
* Re-order patches
