To allow an additional external regulator to be controlled by an mmc host
driver, let's add support for a vqmmc2 regulator to the mmc core.
For an SD UHS-II interface the vqmmc2 regulator may correspond to the so
called vdd2 supply, as described by the SD spec. Initially, only 1.8V is
needed, hence limit the new helper function, mmc_regulator_set_vqmmc2() to
this too.
Note that, to allow for flexibility mmc host drivers need to manage the
enable/disable of the vqmmc2 regulator themselves, while the regulator is
looked up through the common mmc_regulator_get_supply().

To inform the users about SD UHS-II cards, let's extend the print at card
insertion with a "UHS-II" substring. Within this change, it seems
reasonable to convert from using "ultra high speed" into "UHS-I speed", for
the UHS-I type, as it should makes it more clear.
Note that, the new print for UHS-II cards doesn't include the actual
selected speed mode. Instead, this is going to be added from subsequent
change.

The SD UHS-II interface was introduced to the SD spec v4.00 several years
ago. The interface is fundamentally different from an electrical and a
protocol point of view, comparing to the legacy SD interface.
However, the legacy SD protocol is supported through a specific transport
layer (SD-TRAN) defined in the UHS-II addendum of the spec. This allows the
SD card to be managed in a very similar way as a legacy SD card, hence a
lot of code can be re-used to support these new types of cards through the
mmc subsystem.
Moreover, an SD card that supports the UHS-II interface shall also be
backwards compatible with the legacy SD interface, which allows a UHS-II
card to be inserted into a legacy slot. As a matter of fact, this is
already supported by mmc subsystem as of today.
To prepare to add support for UHS-II, this change puts the basic foundation
in the mmc core in place, allowing it to be more easily reviewed before
subsequent changes implements the actual support.
Basically, the approach here adds a new UHS-II bus_ops type and adds a
separate initialization path for the UHS-II card. The intent is to avoid us
from sprinkling the legacy initialization path, but also to simplify
implementation of the UHS-II specific bits.
At this point, there is only one new host ops added to manage the various
ios settings needed for UHS-II. Additional host ops that are needed, are
being added from subsequent changes.

ACMD22 is used to verify the previously write operation. Normally, it
returns the number of written sectors as u32. SDUC, however, returns it
as u64. This is not a superfluous requirement, because SDUC writes may
exceeds 2TB. For Linux mmc however, the previously write operation
could not be more than the block layer limits, thus we make room for a
u64 and cast the returning value to u32.

The SDUC spec expects CMD22 to get squeezed between CMD23 and the
read/write command, e.g. CMD23->CMD22->CMD18 and CMD23->CMD22->CMD25.
At this early stage of adoption, we want to avoid an amid stream of
fixes & quirks of bogus hw, that tends to apply extra logic specifically
around auto-cmd12 & auto-cmd23.
Let's leave close-ended out for now, and re-consider this should those
cards become ubiquitous, if any.
It also means that BLK_FEAT_FUA will not be used for I/O, but instead we
will rely on BLK_FEAT_WRITE_CACHE.

SDUC memory addressing spans beyond 2TB and up to 128TB. Therefore, 38
bits are required to access the entire memory space of all sectors.
Those extra 6 bits are to be carried by CMD22 prior of sending
read/write/erase commands: CMD17, CMD18, CMD24, CMD25, CMD32, and CMD33.
CMD22 will carry the higher order 6 bits, and must precedes any of the
above commands even if it targets sector < 2TB.
No error related to address or length is indicated in CMD22 but rather
in the read/write command itself.

Ultra Capacity SD cards (SDUC) was already introduced in SD7.0. Those
cards support capacity larger than 2TB and up to including 128TB.
ACMD41 was extended to support the host-card handshake during
initialization. The card expects that the HCS & HO2T bits to be set in
the command argument, and sets the applicable bits in the R3 returned
response. On the contrary, if a SDUC card is inserted to a
non-supporting host, it will never respond to this ACMD41 until
eventually, the host will timed out and give up.
Also, add SD CSD version 3.0 - designated for SDUC, and properly parse
the csd register as the c_size field got expanded to 28 bits.
Do not enable SDUC for now - leave it to the last patch in the series.

GIGASTONE Gaming Plus microSD cards manufactured on 02/2022 report that
they support poweroff notification and cache, but they are not working
correctly.
Flush Cache bit never gets cleared in sd_flush_cache() and Poweroff
Notification Ready bit also never gets set to 1 within 1 second from the
end of busy of CMD49 in sd_poweroff_notify().
This leads to I/O error and runtime PM error state.
I observed that the same card manufactured on 01/2024 works as expected.
This problem seems similar to the Kingston cards fixed with
commit c467c8f081 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston

for build, run-time errors, and reporting errors:
-- ftrace: regression test for a kernel crash when running function graph
tracing and then enabling function profiler.
-- rseq: fix for mm_cid test failure.
-- vDSO:
- fixes to reporting skip and other error conditions.
- changes unconditionally build chacha and getrandom tests on

Now that 'remove()' has been converted to the sane new API, there's
no reason for the 'remove_new()' use, so this converts back to the
traditional and simpler name.

Fix rcuog kthread wakeup invocation from softirq context on a CPU
which has been marked offline. This can happen when new callbacks
are enqueued from a softirq on an offline CPU before it calls
rcutree_report_cpu_dead(). When this happens on NOCB configuration,
the rcuog wake-up is deferred through an IPI to an online CPU.
This is done to avoid call into the scheduler which can risk
arming the RT-bandwidth after hrtimers have been migrated out
and disabled. However, doing IPI call from softirq is not allowed
Fix this by forcing deferred rcuog wakeup through the NOCB timer
when the CPU is offline.
