[WHY]
If there are no DC clock limits present, or if the DC limits are the same
as the AC limits, we can disable the AC/DC codepath as there won't be any
validation differences between the two modes.
[HOW]
When all DC power mode clock limits are the same as the max clock
values, there won't be any difference between AC mode and DC mode. Zero
out DC limits that equal max and provide a new cap to indicate the
presence of any non-zero DC mode limit. In summary:
- zero out DC limits that are the same as max clock value
- new dc cap to indicate the presence of DC mode limits
- set limits present if any clock has distinct AC and DC values from SMU

We do not directly enable/disable VCN IRQ in vcn 5.0.0.
And we do not handle the IRQ state as well. So the calls to
disable IRQ and set state are removed. This effectively gets
rid of the warining of
"WARN_ON(!amdgpu_irq_enabled(adev, src, type))"
in amdgpu_irq_put().

Pull vfs rw iterator updates from Christian Brauner:
"The core fs signalfd, userfaultfd, and timerfd subsystems did still
use f_op->read() instead of f_op->read_iter(). Convert them over since
we should aim to get rid of f_op->read() at some point.
Aside from that io_uring and others want to mark files as FMODE_NOWAIT
so it can make use of per-IO nonblocking hints to enable more
efficient IO. Converting those users to f_op->read_iter() allows them
to be marked with FMODE_NOWAIT"

Pull netfs updates from Christian Brauner:
"This reworks the netfslib writeback implementation so that pages read
from the cache are written to the cache through ->writepages(),
thereby allowing the fscache page flag to be retired.
The reworking also:
- builds on top of the new writeback_iter() infrastructure
- makes it possible to use vectored write RPCs as discontiguous
streams of pages can be accommodated
- makes it easier to do simultaneous content crypto and stream
division
- provides support for retrying writes and re-dividing a stream
- replaces the ->launder_folio() op, so that ->writepages() is used
instead
- uses mempools to allocate the netfs_io_request and
netfs_io_subrequest structs to avoid allocation failure in the
writeback path
Some code that uses the fscache page flag is retained for
compatibility purposes with nfs and ceph. The code is switched to
using the synonymous private_2 label instead and marked with
deprecation comments.
The merge commit contains additional details on the new algorithm that
I've left out of here as it would probably be excessively detailed.
On top of the netfslib infrastructure this contains the work to
convert cifs over to netfslib"

Features:
- Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That
means we now have six free FMODE_* bits in total (but bit #6
already got used for FMODE_WRITE_RESTRICTED)
- Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup)
- Add fd_raw cleanup class so we can make use of automatic cleanup
provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well
- Optimize seq_puts()
- Simplify __seq_puts()
- Add new anon_inode_getfile_fmode() api to allow specifying f_mode
instead of open-coding it in multiple places
- Annotate struct file_handle with __counted_by() and use
struct_size()
- Warn in get_file() whether f_count resurrection from zero is
attempted (epoll/drm discussion)
- Folio-sophize aio
- Export the subvolume id in statx() for both btrfs and bcachefs
- Relax linkat(AT_EMPTY_PATH) requirements
- Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors
for dup*() equality replacing kcmp()
Cleanups:
- Compile out swapfile inode checks when swap isn't enabled
- Use (1 << n) notation for FMODE_* bitshifts for clarity
- Remove redundant variable assignment in fs/direct-io
- Cleanup uses of strncpy in orangefs
- Speed up and cleanup writeback
- Move fsparam_string_empty() helper into header since it's currently
open-coded in multiple places
- Add kernel-doc comments to proc_create_net_data_write()
- Don't needlessly read dentry->d_flags twice

- Fix out-of-range warning in nilfs2
- Fix ecryptfs overflow due to wrong encryption packet size
calculation

Pull slab updates from Vlastimil Babka:
"This time it's mostly random cleanups and fixes, with two performance
fixes that might have significant impact, but limited to systems
experiencing particular bad corner case scenarios rather than general
performance improvements.
The memcg hook changes are going through the mm tree due to
dependencies.
- Prevent stalls when reading /proc/slabinfo (Jianfeng Wang)
This fixes the long-standing problem that can happen with workloads
that have alloc/free patterns resulting in many partially used
slabs (in e.g. dentry cache). Reading /proc/slabinfo will traverse
the long partial slab list under spinlock with disabled irqs and
thus can stall other processes or even trigger the lockup
detection. The traversal is only done to count free objects so that
<active_objs> column can be reported along with <num_objs>.
To avoid affecting fast paths with another shared counter
(attempted in the past) or complex partial list traversal schemes
that allow rescheduling, the chosen solution resorts to
approximation - when the partial list is over 10000 slabs long, we
will only traverse first 5000 slabs from head and tail each and use
the average of those to estimate the whole list. Both head and tail
are used as the slabs near head to tend to have more free objects
than the slabs towards the tail.
It is expected the approximation should not break existing
/proc/slabinfo consumers. The <num_objs> field is still accurate
and reflects the overall kmem_cache footprint. The <active_objs>
was already imprecise due to cpu and percpu-partial slabs, so can't
be relied upon to determine exact cache usage. The difference
between <active_objs> and <num_objs> is mainly useful to determine
the slab fragmentation, and that will be possible even with the
approximation in place.
- Prevent allocating many slabs when a NUMA node is full (Chen Jun)
Currently, on NUMA systems with a node under significantly bigger
pressure than other nodes, the fallback strategy may result in each
kmalloc_node() that can't be safisfied from the preferred node, to
allocate a new slab on a fallback node, and not reuse the slabs
already on that node's partial list.
This is now fixed and partial lists of fallback nodes are checked
even for kmalloc_node() allocations. It's still preferred to
allocate a new slab on the requested node before a fallback, but
only with a GFP_NOWAIT attempt, which will fail quickly when the
node is under a significant memory pressure.
- More SLAB removal related cleanups (Xiu Jianfeng, Hyunmin Lee)
- Fix slub_kunit self-test with hardened freelists (Guenter Roeck)
- Mark racy accesses for KCSAN (linke li)

Pull kcsan update from Paul McKenney:
"Introduce __data_racy type qualifier
This adds a __data_racy type qualifier that enables kernel developers
to inform KCSAN that a given variable is a shared variable without
needing to mark each and every access.
This allows pre-KCSAN code to be correctly (if approximately)
instrumented withh very little effort, and also provides people
reading the code a clear indication that the variable is in fact
shared.
In addition, it permits incremental transition to per-access KCSAN
marking, so that (for example) a given subsystem can be transitioned
one variable at a time, while avoiding large numbers of KCSAN warnings
during this transition"

The ABI documentation indicates that field separators do not need a
space between them, only a ';'. When no spacing is used, the register
must work. Any subsequent register, with or without spaces, must match
and not return -EADDRINUSE.
Add a non-spacing separator case to our self-test register case to ensure
it works going forward.

When the ABI was updated to prevent same name w/different args, it
missed an important corner case when fields don't end with a space.
Typically, space is used for fields to help separate them, like
"u8 field1; u8 field2". If no spaces are used, like
"u8 field1;u8 field2", then the parsing works for the first time.
However, the match check fails on a subsequent register, leading to
confusion.
This is because the match check uses argv_split() and assumes that all
fields will be split upon the space. When spaces are used, we get back
{ "u8", "field1;" }, without spaces we get back { "u8", "field1;u8" }.
This causes a mismatch, and the user program gets back -EADDRINUSE.
Add a method to detect this case before calling argv_split(). If found
force a space after the field separator character ';'. This ensures all
cases work properly for matching.
With this fix, the following are all treated as matching:
u8 field1;u8 field2
u8 field1; u8 field2
u8 field1;\tu8 field2
u8 field1;\nu8 field2

Pull alpha updates from Arnd Bergmann:
"I had investigated dropping support for alpha EV5 and earlier a while
ago after noticing that this is the only supported CPU family in the
kernel without native byte access and that Debian has already dropped
support for this generation last year [1] in order to improve
performance for the newer machines.
This topic came up again when Paul McKenney noticed that parts of the
RCU code already rely on byte access and do not work on alpha EV5
reliably, so we decided on using my series to avoid the problem
entirely.
Al Viro did another series for alpha to address all the known build
issues. I rebased his patches without any further changes and included
it as a baseline for my work here to avoid conflicts and allow
backporting the fixes to stable kernels for the now removed hardware
support as well"
[ I dearly loved alpha back in the days, but the lack of byte and word
operations was a horrible mistake and made everything worse -
including very much the crazy IO contortions that resulted from it.
It certainly wasn't the only mistake in the architecture, but it's the
first-order issue.
So while it's a bit sad to see the support for my first alpha go away,
if you want to run museum hardware, maybe you should use museum
kernels.. - Linus ]
