ab128251da media: dt-bindings: qcom,sm8250-venus: sort out power domains
First of all, on SM8250 Iris (ex-Venus) core needs to scale clocks which
are powered by the MMCX domain. Add MMCX domain to the list of the power
domain to be used on this platform.

cannot be defined in top-level allOf:if:then:properties:, because it

since child nodes do not have clocks at all, there is little point in
disallowing them in the first place.

8c16c1c001 ntfs: fix empty_buf and ra lifetime bugs in ntfs_empty_logfile()
ntfs_empty_logfile() has three related allocator bugs around the
@empty_buf and @ra buffers it uses inside the per-cluster loop.

When the loop encounters a runlist entry with LCN_RL_NOT_MAPPED, the
function kvfrees @empty_buf and goes to map_vcn to remap.  @empty_buf
is not cleared.  If ntfs_map_runlist_nolock() fails on re-entry,
control jumps to the err label which kvfrees @empty_buf a second time.

In the same branch, @ra is left allocated.  When the remap succeeds
the function falls through the @empty_buf re-allocation and the @ra
re-allocation, overwriting the previous @ra pointer and leaking it.

The success path frees @empty_buf with kfree() instead of kvfree().
kvzalloc() may fall back to vmalloc(), in which case kfree() does not
correctly release the memory.

A KASAN-enabled QEMU harness mirroring this control flow reports
"BUG: KASAN: double-free" when the second ntfs_map_runlist_nolock()
fails.

Clear both @empty_buf and @ra after the in-loop releases so the err
path is a no-op when the buffers have already been freed and so the
remap-success path does not leak the previous @ra.  Switch the success
path to kvfree() to match the @empty_buf allocator.

c41f66ea9d clk: qcom: dispcc-x1e80100: Fix (possibly) dumping regmap
Reading few registers at the end of the block (e.g. 0x10000, 0x10004)
might result in synchronous external abort, so limit the regmap to the
last readable register which allows dumping the regs for debugging.

bde860892c arm64: dts: qcom: purwa: Add EL2 overlay for purwa-iot-evk
Add support for building an EL2 combined DTB for the purwa-iot-evk
in the Qualcomm DTS Makefile.

The new purwa-iot-evk-el2.dtb is generated by combining the base
purwa-iot-evk.dtb with the x1-el2.dtbo overlay, enabling EL2-specific
configurations required by the platform.

bc27dbefae clk: qcom: x1e80100-dispcc: Stop disp_cc_mdss_mdp_clk_src from getting parked
Parking disp_cc_mdss_mdp_clk_src at 19.2MHz causing the EFI GOP framebuffer
to stop functioning. The EFI GOP framebuffer should keep working until
the msm display driver loads, to help with boot debugging and to ensure
display output when the msm module is not in the initramfs.

Switch disp_cc_mdss_mdp_clk_src over to clk_rcg2_shared_no_init_park_ops
to keep the EFI GOP working after binding the x1e80100-dispcc driver.

79602b750b soc: qcom: smem: Switch partitions to xarray
The partitions array is currently statically sized and uses the remote
host ID as an index.

Future protocol improvements to allow for more than two hosts in a
partition will require hostIDs to be bitwise significant integers.
This will result in large, sparse host IDs that generally exceed the
current static limit.

Switch to using xarray to efficiently handle these sparse indices and
allow for dynamic growth.

3ac1a467e3 bpf: Fix off-by-one boundary validation in arena direct-value access
BPF_MAP_TYPE_ARENA accepts BPF_PSEUDO_MAP_VALUE offsets at exactly
the end of the arena mapping (off == arena_size). The boundary check
in arena_map_direct_value_addr() uses `>` instead of `>=`, which
incorrectly allows a one-past-end pointer to be accepted.

Change the condition to `>=` to correctly reject offsets that fall
outside the valid arena user_vm range.

bf6d507f7e xskmap: reject TX-only AF_XDP sockets
XSKMAP entries are used as redirect targets for incoming XDP frames.
A TX-only AF_XDP socket lacks an Rx ring and cannot handle redirected
traffic, but xsk_map_update_elem() currently allows such sockets to
be inserted into the map.

Redirecting packets to such a socket on the veth generic-XDP path
causes a kernel crash in xsk_generic_rcv().

This became possible after xsk_is_setup_for_bpf_map() was removed from
the XSKMAP update path, which allowed bound TX-only sockets to be
inserted into the map.

Reject TX-only sockets during XSKMAP updates to avoid the crash.
They remain fully operational for pure Tx purposes outside XSKMAP.

512809bb8a bpf: Don't run arg-tracking analysis twice on main subprog
Because subprog 0, the main subprog, is considered a global function,
we end up running the arg-tracking dataflow analysis twice on it. That
results in slightly longer verification but mostly in more verbose
verifier logs. This patch fixes it by keeping only the iteration over
global subprogs.

When running over all of Cilium's programs with BPF_LOG_LEVEL2, this
reduces verbosity by ~20% on average.

cf52058dcd lib/crypto: powerpc/md5: Drop powerpc optimized MD5 code
MD5 is obsolete, is vulnerable to collision attacks, and is being
replaced by SHA-256 in new systems.  It doesn't make sense to continue
to maintain architecture-optimized implementations of MD5.  Effort
should be spent on modern algorithms.

Indeed, architecture-optimized MD5 code remains only for powerpc.  It
was already removed from mips and sparc, and it never existed for any
other architecture (e.g. x86, arm, or arm64) in the first place.
Earlier the decision was made to keep the powerpc MD5 code for a while
anyway because of someone using it via AF_ALG via libkcapi-hasher
(https://lore.kernel.org/r/f0d771d5-ed70-444c-957a-ad4c16f6c115@csgroup.eu/)

However, with AF_ALG itself now being on its way out due to its
continuous stream of security vulnerabilities
(https://lore.kernel.org/r/20260430011544.31823-1-ebiggers@kernel.org/),
it's also time to be a bit more forceful with nudging people towards
userspace crypto code.  It's always been the better solution anyway, and
it's much more efficient if properly optimized code is used.

Note that the md5-asm.S file contains no privileged instructions and
could be run in userspace just fine.

Thus, we now have two factors going against keeping the powerpc MD5
code.  Different people might weigh these two factors differently, but I
think the two of them together make the removal the clear choice.

Let's remove it.

03d958da4f sched_ext: Fix ops_cid layout assert
ca1d48a86f ("sched_ext: Use offsetofend on both sides of the ops_cid
layout assert") replaced sizeof() with offsetofend() to dodge 32-bit
PPC trailing padding, but the resulting check is tautological: with
CID_OFFSET_MATCH(priv, priv) already enforcing offsetof(priv) equality
and @priv being the same type in both structs, the two offsetofends
are equal by construction. The original protection - catching a stray
field added past @priv in sched_ext_ops_cid - is gone.

Anchor on a zero-size __end[] marker appended after @priv. Its offset
sits flush after @priv regardless of trailing struct padding; if a
field is inserted past @priv, __end shifts and the assert fires.
