mmc: core: Extend support for mmc regulators with a vqmmc2
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().
mmc: core: Announce successful insertion of an SD UHS-II card
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.
mmc: core: Cleanup printing of speed mode at card insertion
The current print of the bus speed mode in mmc_add_card() has grown over
the years and is now difficult to parse. Let's clean up the code and also
take the opportunity to properly announce "DDR" for eMMCs as
"high speed DDR", which is according to the eMMC spec.

Pull driver core fixes from Greg KH:
"Here is a single driver core fix, and a .mailmap update.
The fix is for the rust driver core bindings, turned out that the
from_raw binding wasn't a good idea (don't want to pass a pointer to a
reference counted object without actually incrementing the pointer.)
So this change fixes it up as the from_raw binding came in in -rc1.
The other change is a .mailmap update.
Both have been in linux-next for a while with no reported issues"

"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"

Commit ac9f97ff8b32 ("powerpc/8xx: Inconditionally use task PGDIR in
DTLB misses") relies on re-reading DAR register to know if an error is
due to a missing copy of a PMD entry in task's PGDIR, allthough DAR
was already read in the exception prolog and copied into thread
struct. This is because is it done very early in the exception and
there are not enough registers available to keep a pointer to thread
struct.
However, dcbz instruction is buggy and doesn't update DAR register on
fault. That is detected and generates a call to FixupDAR workaround
which updates DAR copy in thread struct but doesn't fix DAR register.
Let's fix DAR in addition to the update of DAR copy in thread struct.
