Currently, --entries uses -e as the short version in the hist mode of
timerlat and osnoise tools. But as -e is already used to enable events
on trace sessions by other tools, thus let's keep it available for the
same usage for all rtla tools.
Make -E the short version of --entries for hist mode on all tools.
Note: rtla was merged in this merge window, so rtla was not released yet.

Add KVM_CAP_PPC_AIL_MODE_3 to advertise the capability to set the AIL
resource mode to 3 with the H_SET_MODE hypercall. This capability
differs between processor types and KVM types (PR, HV, Nested HV), and
affects guest-visible behaviour.
QEMU will implement a cap-ail-mode-3 to control this behaviour[1], and
use the KVM CAP if available to determine KVM support[2].

ASoC: Fixes for v5.18
More fixes that have arrived in the past few -rcs, plus a MAINTAINERS
update. The biggest update here is the fix for control change
notifications in ASoC generic controls found by mixer-test.
The problem I'm addressing was discovered by the LTP test covering
cve-2018-1000204.
A short description of what happens follows:
1) The test case issues a command code 00 (TEST UNIT READY) via the SG_IO
interface with: dxfer_len == 524288, dxdfer_dir == SG_DXFER_FROM_DEV
and a corresponding dxferp. The peculiar thing about this is that TUR
is not reading from the device.
2) In sg_start_req() the invocation of blk_rq_map_user() effectively
bounces the user-space buffer. As if the device was to transfer into
it. Since commit a45b599ad8 ("scsi: sg: allocate with __GFP_ZERO in
sg_build_indirect()") we make sure this first bounce buffer is
allocated with GFP_ZERO.
3) For the rest of the story we keep ignoring that we have a TUR, so the
device won't touch the buffer we prepare as if the we had a
DMA_FROM_DEVICE type of situation. My setup uses a virtio-scsi device
and the buffer allocated by SG is mapped by the function
virtqueue_add_split() which uses DMA_FROM_DEVICE for the "in" sgs (here
scatter-gather and not scsi generics). This mapping involves bouncing
via the swiotlb (we need swiotlb to do virtio in protected guest like
s390 Secure Execution, or AMD SEV).
4) When the SCSI TUR is done, we first copy back the content of the second
(that is swiotlb) bounce buffer (which most likely contains some
previous IO data), to the first bounce buffer, which contains all
zeros. Then we copy back the content of the first bounce buffer to
the user-space buffer.
5) The test case detects that the buffer, which it zero-initialized,
ain't all zeros and fails.
One can argue that this is an swiotlb problem, because without swiotlb
we leak all zeros, and the swiotlb should be transparent in a sense that
it does not affect the outcome (if all other participants are well
behaved).
Copying the content of the original buffer into the swiotlb buffer is
the only way I can think of to make swiotlb transparent in such
scenarios. So let's do just that if in doubt, but allow the driver
to tell us that the whole mapped buffer is going to be overwritten,
in which case we can preserve the old behavior and avoid the performance
impact of the extra bounce.

Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
Over time dma-buf-map grew up to more functionality than the one used by
dma-buf: in fact it's just a shim layer to abstract system memory, that
can be accessed via regular load and store, from IO memory that needs to
be acessed via arch helpers.
The idea is to extend this API so it can fulfill other needs, internal
to a single driver. Example: in the i915 driver it's desired to share
the implementation for integrated graphics, which uses mostly system
memory, with discrete graphics, which may need to access IO memory.
The conversion was mostly done with the following semantic patch:

Then some files had their includes adjusted and some comments were
update to remove mentions to dma-buf-map.
Since this is not specific to dma-buf anymore, move the documentation to
the "Bus-Independent Device Accesses" section.
v2:
- Squash patches
v3:
- Fix wrong removal of dma-buf.h from MAINTAINERS
- Move documentation from dma-buf.rst to device-io.rst
v4:
- Change documentation title and level

Fixes for omaps
A series of fixes for omap variants for minor issues, and a fix for a timer
regression for some omap3 beagleboard versions.
The timer fix needs to patch both the dts and the timer code because
otherwise the timer quirk handling for old dtbs will prevent the dts fix
from working.
The other changes are for issues found by automated analysis, a macasp
typo fix, and two cosmetic fixes for clocks.

Pull drm fixes from Dave Airlie:
"Regular fixes for the week. Daniel has agreed to bring back the fbcon
hw acceleration under a CONFIG option for the non-drm fbdev users, we
don't advise turning this on unless you are in the niche that is old
fbdev drivers, Since it's essentially a revert and shouldn't be high
impact seemed like a good time to do it now.
Otherwise, i915 and amdgpu fixes are most of it, along with some minor
fixes elsewhere.
fbdev:
- readd fbcon acceleration
i915:
- fix DP monitor via type-c dock
- fix for engine busyness and read timeout with GuC
- use ALLOW_FAIL for error capture buffer allocs
- don't use interruptible lock on error paths
- smatch fix to reject zero sized overlays.
amdgpu:
- mGPU fan boost fix for beige goby
- S0ix fixes
- Cyan skillfish hang fix
- DCN fixes for DCN 3.1
- DCN fixes for DCN 3.01
