Define how to handle buffers with multiple possible placement so we
don't get incompatible implementations. Callout the resident requirement
for drm-purgeable- explicitly. Remove the requirement for there to be
only drm-memory- or only drm-resident-, it's not what's implemented and
having both is better for back-compat. Also re-order the paragraphs to
flow better.

The DP subsystem for ZynqMP supports audio via two channels, and the DP
DMA has dma-engines for those channels. For some reason the DT binding
has not specified those channels, even if the picture included in
xlnx,zynqmp-dpsub.yaml shows "2 x aud" DMAs.
This hasn't caused any issues as the drivers have not supported audio,
and has thus gone unnoticed.
To make it possible to add the audio support to the driver, add the two
audio DMAs to the binding. While strictly speaking this is an ABI break,
there should be no regressions caused by this as we're adding new
entries at the end of the dmas list, and, after the audio support has
been added in "arm64: dts: zynqmp: Add DMA for DP audio", the driver
will treat the audio DMAs as optional to also support the old bindings.

Pull arm64 fixes from Catalin Marinas:
"Nothing major, some left-overs from the recent merging window (MTE,
coco) and some newly found issues like the ptrace() ones.
- MTE/hugetlbfs:
- Set VM_MTE_ALLOWED in the arch code and remove it from the core
code for hugetlbfs mappings
- Fix copy_highpage() warning when the source is a huge page but
not MTE tagged, taking the wrong small page path
- drivers/virt/coco:
- Add the pKVM and Arm CCA drivers under the arm64 maintainership
- Fix the pkvm driver to fall back to ioremap() (and warn) if the
MMIO_GUARD hypercall fails
- Keep the Arm CCA driver default 'n' rather than 'm'
- A series of fixes for the arm64 ptrace() implementation,
potentially leading to the kernel consuming uninitialised stack
variables when PTRACE_SETREGSET is invoked with a length of 0
- Fix zone_dma_limit calculation when RAM starts below 4GB and
ZONE_DMA is capped to this limit
- Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a
call to page_to_phys() (from patch_map()) which checks pfn_valid()
before vmemmap has been set up
- Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI
ops when the kernel assumes 8-bit ASIDs but running under a
hypervisor on a system that implements 16-bit ASIDs (found running
Linux under Parallels on Apple M4)
- ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A as it
is using the same SMMU PMCG as HIP09 and suffers from the same
errata
- Add GCS to cpucap_is_possible(), missed in the recent merge"

can be aged out of the cache.
Bug Fixes:
- fix 'Do simple duplicate message elimination' to clear previous
state when updating in capability audit cache
- Fix memory leak for aa_unpack_strdup()
- properly handle cx/px lookup failure when in complain mode
- allocate xmatch for nullpdb inside aa_alloc_null fixing a NULL ptr
deref of tracking profiles in when in complain mode
Cleanups:
- Remove everything being reported as deadcode
- replace misleading 'scrubbing environment' phrase in debug print
- Remove unnecessary NULL check before kvfree()
- clean up duplicated parts of handle_onexec()
- Use IS_ERR_OR_NULL() helper function
- move new_profile declaration to top of block instead immediately
after label to remove C23 extension warning
Documentation:
- add comment to document capability.c:profile_capable ad ptr
parameter can not be NULL
- add comment to document first entry is in packed perms struct is
reserved for future planned expansion.
- Update LSM/apparmor.rst add blurb for DEFAULT_SECURITY_APPARMOR"

Pull more tracing updates from Steven Rostedt:
- Add trace flag for NEED_RESCHED_LAZY
Now that NEED_RESCHED_LAZY is upstream, add it to the status bits of
the common_flags. This will now show when the NEED_RESCHED_LAZY flag
is set that is used for debugging latency issues in the kernel via a
trace.
- Remove leftover "__idx" variable when SRCU was removed from the
tracepoint code
- Add rcu_tasks_trace guard
To add a guard() around the tracepoint code, a rcu_tasks_trace guard
needs to be created first.
- Remove __DO_TRACE() macro and just call __DO_TRACE_CALL() directly
The DO_TRACE() macro has conditional locking depending on what was
passed into the macro parameters. As the guts of the macro has been
moved to __DO_TRACE_CALL() to handle static call logic, there's no
reason to keep the __DO_TRACE() macro around.
It is better to just do the locking in place without the conditionals
and call __DO_TRACE_CALL() from those locations. The "cond" passed in
can also be moved out of that macro. This simplifies the code.
- Remove the "cond" from the system call tracepoint macros
The "cond" variable was added to allow some tracepoints to check a
condition within the static_branch (jump/nop) logic. The system calls
do not need this. Removing it simplifies the code.
- Replace scoped_guard() with just guard() in the tracepoint logic
guard() works just as well as scoped_guard() in the tracepoint logic
and the scoped_guard() causes some issues.

ASoC: Fixes for v6.13
A pile of driver specific quirks and fixes that came in since the merge
window. One of the AMD fixes is a bit broken for some systems, I'm
expecting an incremental change to fix that but it seems better overall
to merge the rest of the fixes.
There's also one small documentation update that seemed sensible to
apply now, pointing to the dapm-graph tool.
Unless an explicit O= option is provided, external module builds must
start from the kernel directory.
This can be achieved by using the -C option:
$ make -C /path/to/kernel M=/path/to/external/module
This commit allows starting external module builds from any directory,
so you can also do the following:
$ make -f /path/to/kernel/Makefile M=/path/to/external/module
The key difference is that the -C option changes the working directory
and parses the Makefile located there, while the -f option only
specifies the Makefile to use.
As shown in the examples in Documentation/kbuild/modules.rst, external
modules usually have a wrapper Makefile that allows you to build them
without specifying any make arguments. The Makefile typically contains
a rule as follows:
KDIR ?= /path/to/kernel
default:
$(MAKE) -C $(KDIR) M=$(CURDIR) $(MAKECMDGOALS)
The log will appear as follows:
$ make
make -C /path/to/kernel M=/path/to/external/module
make[1]: Entering directory '/path/to/kernel'
make[2]: Entering directory '/path/to/external/module'
CC [M] helloworld.o
MODPOST Module.symvers
CC [M] helloworld.mod.o
CC [M] .module-common.o
LD [M] helloworld.ko
make[2]: Leaving directory '/path/to/external/module'
make[1]: Leaving directory '/path/to/kernel'
This changes the working directory twice because the -C option first
switches to the kernel directory, and then Kbuild internally recurses
back to the external module directory.
With this commit, the wrapper Makefile can directly include the kernel
Makefile:
KDIR ?= /path/to/kernel
export KBUILD_EXTMOD := $(realpath $(dir $(lastword $(MAKEFILE_LIST))))
include $(KDIR)/Makefile
This avoids unnecessary sub-make invocations:
$ make
CC [M] helloworld.o
MODPOST Module.symvers
CC [M] helloworld.mod.o
CC [M] .module-common.o
LD [M] helloworld.ko

There has been a long-standing request to support building external
modules in a separate build directory.
This commit introduces a new environment variable, KBUILD_EXTMOD_OUTPUT,
and its shorthand Make variable, MO.
A simple usage:
$ make -C <kernel-dir> M=<module-src-dir> MO=<module-build-dir>

Currently, Kbuild always operates in the output directory of the kernel,
even when building external modules. This increases the risk of external
module Makefiles attempting to write to the kernel directory.
This commit switches the working directory to the external module
directory, allowing the removal of the $(KBUILD_EXTMOD)/ prefix from
some build artifacts.
The command for building external modules maintains backward
compatibility, but Makefiles that rely on working in the kernel
directory may break. In such cases, $(objtree) and $(srctree) should
be used to refer to the output and source directories of the kernel.
The appearance of the build log will change as follows:
[Before]
$ make -C /path/to/my/linux M=/path/to/my/externel/module
make: Entering directory '/path/to/my/linux'
CC [M] /path/to/my/externel/module/helloworld.o
MODPOST /path/to/my/externel/module/Module.symvers
CC [M] /path/to/my/externel/module/helloworld.mod.o
CC [M] /path/to/my/externel/module/.module-common.o
LD [M] /path/to/my/externel/module/helloworld.ko
make: Leaving directory '/path/to/my/linux'
[After]
$ make -C /path/to/my/linux M=/path/to/my/externel/module
make: Entering directory '/path/to/my/linux'
make[1]: Entering directory '/path/to/my/externel/module'
CC [M] helloworld.o
MODPOST Module.symvers
CC [M] helloworld.mod.o
CC [M] .module-common.o
LD [M] helloworld.ko
make[1]: Leaving directory '/path/to/my/externel/module'
make: Leaving directory '/path/to/my/linux'
Printing "Entering directory" twice is cumbersome. This will be
addressed later.
