For smoother upgrade path, keep the previous CONFIG_SND_HDA_CODEC_HDMI
as the meuconfig, so that the kconfig can be taken over from the
previous config. The all belonging HDMI codec drivers are enabled as
default as long as CONFIG_SND_HDA_CODEC_HDMI is set.
This is only about the default config, and each driver can be still
disabled if user wants to reduce the size, too.
The kconfig for the generic HDMI driver is changed to
CONFIG_SND_HDA_CODEC_HDMI_GENERIC along with this action.

The recent split of Realtek HD-audio driver forced users to choose the
right Kconfigs, but most users have no idea which ones to enable.
Although the distros tend to enable all of them, individual users may
have their own favorites and miss something needed via the version
upgrade.
For smoother upgrade path from the previous kernel configuration, now
we take the following changes:
- CONFIG_SND_HDA_CODEC_REALTEK (which is a menuconfig) is changed from
bool to tristate again, so that it can take over from the previous
config gracefully.
- CONFIG_SND_HDA_CODEC_ALC* receive "default y", so that they are
enabled as default as long as CONFIG_SND_HDA_CODEC_REALTEK is set.
Those can be still disabled if users want to reduce the size, too.
At least this allows users to run "make oldconfig" and push RETURN
blindly.

Move scheduler tags (sched_tags) allocation and deallocation outside
both the ->elevator_lock and ->freeze_lock when updating nr_hw_queues.
This change breaks the dependency chain from the percpu allocator lock
to the elevator lock, helping to prevent potential deadlocks, as
observed in the reported lockdep splat[1].
This commit introduces batch allocation and deallocation helpers for
sched_tags, which are now used from within __blk_mq_update_nr_hw_queues
routine while iterating through the tagset.
With this change, all sched_tags memory management is handled entirely
outside the ->elevator_lock and the ->freeze_lock context, thereby
eliminating the lock dependency that could otherwise manifest during
nr_hw_queues updates.

Recent lockdep reports [1] have revealed a potential deadlock caused by a
lock dependency between the percpu allocator lock and the elevator lock.
This issue can be avoided by ensuring that the allocation and release of
scheduler tags (sched_tags) are performed outside the elevator lock.
Furthermore, the queue does not need to be remain frozen during these
operations.
To address this, move all sched_tags allocations and deallocations outside
of both the ->elevator_lock and the ->freeze_lock. Since the lifetime of
the elevator queue and its associated sched_tags is closely tied, the
allocated sched_tags are now stored in the elevator queue structure. Then,
during the actual elevator switch (which runs under ->freeze_lock and
->elevator_lock), the pre-allocated sched_tags are assigned to the
appropriate q->hctx. Once the elevator switch is complete and the locks
are released, the old elevator queue and its associated sched_tags are
freed.
This commit specifically addresses the allocation/deallocation of sched_
tags during elevator switching. Note that sched_tags may also be allocated
in other contexts, such as during nr_hw_queues updates. Supporting that
use case will require batch allocation/deallocation, which will be handled
in a follow-up patch.
This restructuring ensures that sched_tags memory management occurs
entirely outside of the ->elevator_lock and ->freeze_lock context,
eliminating the lock dependency problem seen during scheduler updates.

In preparation for allocating sched_tags before freezing the request
queue and acquiring ->elevator_lock, move the elevator queue allocation
logic from the elevator ops ->init_sched callback into blk_mq_init_sched.
As elevator_alloc is now only invoked from block layer core, we don't
need to export it, so unexport elevator_alloc function.
This refactoring provides a centralized location for elevator queue
initialization, which makes it easier to store pre-allocated sched_tags
in the struct elevator_queue during later changes.

These macros had initially no frequency field. When I added the "maximum
operation frequency" field, I did it initially on very common macros and
I decided to add an optional field for that (with VA_ARGS) in order to
prevent massively unreadable changes. I then added new variants in the
spinand.h header, and requested a frequency field for them by
default. Some times later, I also added maximum frequencies to other
existing variants, but I did it incorrectly, without noticing I was
wrong because the field was optional.
This mix is error prone, so let's do what I should have done since the
very beginning: add a frequency field to all READ_FROM_CACHE variants.
There is no functional change.

In order to pick the best variant, the duration of each typical
operation is derived and then compared. These durations are based on the
maximum capabilities of the chips, which are commonly the limiting
factors. However there are other possible limiting pieces, such as the
hardware layout, EMC considerations and in some cases, the SPI controller
itself.
We need to take this into account to further refine our variant choice,
so let's use the actual frequency that will be used for the operation
instead of the theoretical maximum.

spi_mem_calc_op_duration() is deriving the duration of a specific op, by
multiplying the number of cycles with the time a cycle will last. This
time was measured in nanoseconds, which means at high frequencies the
delta between two frequencies might not be properly catch due to
roundings.
For instance, the Winbond driver has a changing number of dummy cycles
depending on the speed, adding +8 dummy cycles when running at 166MHz
compared to 162MHz.
Both frequencies would lead to using a 6ns delay per cycle for the op
duration computation, whereas in practice there is a small difference
which actually offsets the number of extra dummy cycles on a normal page
read.
Augmenting the precision of the calculation by using picoseconds
prevents selecting a lower frequency if we can do slightly better with
another frequency involving more cycles. As a result, the above
situation leads to comparing cycles of 6024 and 6172 picoseconds which
leads to picking the most efficient variant.

"A quick summary: perf support for Branch Record Buffer Extensions
(BRBE), typical PMU hardware updates, small additions to MTE for
store-only tag checking and exposing non-address bits to signal

There is also a TLBI optimisation on hardware that does not require
break-before-make when changing the user PTEs between contiguous and
non-contiguous.

- Standardize on the __ASSEMBLER__ macro that is provided by GCC
and Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__
in both uapi and non-uapi headers
- Explicitly include <linux/export.h> in architecture and driver
files which contain an EXPORT_SYMBOL() and remove the include
from the files which do not contain the EXPORT_SYMBOL()
- Use the full title of "z/Architecture Principles of Operation"
manual and the name of a section where facility bits are listed
- Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid
unnecessary slowing down of the build and confusing external
kABI tools that process symtypes data
- Print additional unrecoverable machine check information to make
the root cause analysis easier
- Move cmpxchg_user_key() handling to uaccess library code, since
the generated code is large anyway and there is no benefit if it
is inlined
- Fix a problem when cmpxchg_user_key() is executing a code with a
non-default key: if a system is IPL-ed with "LOAD NORMAL", and
the previous system used storage keys where the fetch-protection
bit was set for some pages, and the cmpxchg_user_key() is located
within such page, a protection exception happens
- Either the external call or emergency signal order is used to send
an IPI to a remote CPU. Use the external order only, since it is at
least as good and sometimes even better, than the emergency signal
- In case of an early crash the early program check handler prints
more or less random value of the last breaking event address, since
it is not initialized properly. Copy the last breaking event address
from the lowcore to pt_regs to address this
- During STP synchronization check udelay() can not be used, since the
first CPU modifies tod_clock_base and get_tod_clock_monotonic() might
return a non-monotonic time. Instead, busy-loop on other CPUs, while
the the first CPU actually handles the synchronization operation
- When debugging the early kernel boot using QEMU with the -S flag and
GDB attached, skip the decompressor and start directly in kernel
- Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture
Principles of Operation" manual
- Remove the in-kernel time steering support in favour of the new s390
PTP driver, which allows the kernel clock steered more precisely
- Remove a possible false-positive warning in pte_free_defer(), which
could be triggered in a valid case KVM guest process is initializing
