DAMON's virtual address space operation set implementation (vaddr) calls
pte_offset_map_lock() inside the page table walk callback function. This
is for reading and writing page table accessed bits. If
pte_offset_map_lock() fails, it retries by returning the page table walk
callback function with ACTION_AGAIN.
pte_offset_map_lock() can continuously fail if the target is a pmd
migration entry, though. Hence it could cause an infinite page table walk
if the migration cannot be done until the page table walk is finished.
This indeed caused a soft lockup when CPU hotplugging and DAMON were
running in parallel.
Avoid the infinite loop by simply not retrying the page table walk. DAMON
is promising only a best-effort accuracy, so missing access to such pages
is no problem.

A vmalloc allocation is preserved using binary structure similar to global
KHO memory tracker. It's a linked list of pages where each page is an
array of physical address of pages in vmalloc area.
kho_preserve_vmalloc() hands out the physical address of the head page to
the caller. This address is used as the argument to kho_vmalloc_restore()
to restore the mapping in the vmalloc address space and populate it with
the preserved pages.

Patch series "kho: add support for preserving vmalloc allocations", v5.
Following the discussion about preservation of memfd with LUO [1] these
patches add support for preserving vmalloc allocations.
Any KHO uses case presumes that there's a data structure that lists
physical addresses of preserved folios (and potentially some additional
metadata). Allowing vmalloc preservations with KHO allows scalable
preservation of such data structures.
For instance, instead of allocating array describing preserved folios in
the fdt, memfd preservation can use vmalloc:
preserved_folios = vmalloc_array(nr_folios, sizeof(*preserved_folios));
memfd_luo_preserve_folios(preserved_folios, folios, nr_folios);
kho_preserve_vmalloc(preserved_folios, &folios_info);
This patch (of 4):
Instead of checking if kho is finalized in each caller of
__kho_preserve_order(), do it in the core function itself.

The point of isolating code that uses kernel mode FPU in separate
compilation units is to ensure that even implicit uses of, e.g., SIMD
registers for spilling occur only in a context where this is permitted,
i.e., from inside a kernel_fpu_begin/end block.
This is important on arm64, which uses -mgeneral-regs-only to build all
kernel code, with the exception of such compilation units where FP or
SIMD registers are expected to be used. Given that the compiler may
invent uses of FP/SIMD anywhere in such a unit, none of its code may be
accessible from outside a kernel_fpu_begin/end block.
This means that all callers into such compilation units must use the
DC_FP start/end macros, which must not occur there themselves. For
robustness, all functions with external linkage that reside there should
call dc_assert_fp_enabled() to assert that the FPU context was set up
correctly.
Fix this for the DCN35, DCN351 and DCN36 implementations.

Commit 27758d8c25 ("kbuild: enable -Werror for hostprogs")
unconditionally enabled -Werror for the compiler, assembler, and linker
when building the host programs, as the build footprint of the host
programs is small (thus risk of build failures from warnings are low)
and that stage of the build may not have Kconfig values (thus
CONFIG_WERROR could not be used as a precondition).
While turning warnings into errors unconditionally happens in a few
places within the kernel, it can be disruptive to people who may be
building with newer compilers, such as while doing a bisect. While it is
possible to avoid this behavior by passing HOSTCFLAGS=-w or
HOSTCFLAGS=-Wno-error, it may not be the most intuitive for regular
users not intimately familiar with Kbuild.
Avoid being disruptive to the entire build by depending on the explicit
opt-in of CONFIG_WERROR or W=e to enable -Werror and the like while
building the host programs. While this means there is a small portion of
the build that does not have -Werror enabled (namely scripts/kconfig/*
and scripts/basic/fixdep), it is better than not having it altogether.

Pull clk updates from Stephen Boyd:
"There's a bunch of patches here across drivers/clk/ to migrate drivers
to use struct clk_ops::determine_rate() instead of the round_rate()
one so that we can remove the round_rate clk_op entirely. Brian has
taken up that task which nobody else has wanted to do for close to a
decade. Thanks Brian!
This is all prerequisite work to get to the real task of improving the
clk rate setting process. Once we have determine_rate() used
everywhere, we'll be able to do things like chain the rate request
structs in linked lists to order the rate setting operations or add
more parameters without having to change every clk driver in
existence. It's also nice to not have multiple ways to do something
which just causes confusion for clk driver authors. Overall I'm glad
this is getting done.
Beyond this change we also have a tweak to the clk_lookup() function
in the core framework to use hashing on the clk name instead of a clk
tree walk with string comparisons. We _still_ rely on the clk name to
be unique, because historically we've used globally unique strings to
describe the clk tree topology. This tree walk becomes increasingly
slow as more clks are added to the system. Searching from the roots
for a duplicate is simple but pretty dumb and it wastes boot time so
we're using a hash table as an improvement. Ideally we wouldn't rely
on the strings to be unique at all, relegating them to simply debug
information, but that is future work that will likely require some
sort of Kconfig knob indicating strings aren't used for topology
description.
Outside of the core framework changes we have the usual new SoC
support and fixes to clk drivers for things that were discovered once
the clks were used by consumer drivers. Nothing in particular is
jumping out at me in the "misc" pile, except maybe the Amlogic driver
that has gone through a refactoring. That series got a fix from
testing in -next though so it seems likely that things have been
getting good test coverage for a couple weeks already"
