blk_keyslot_manager is misnamed because it doesn't necessarily manage
keyslots. It actually does several different things:
- Contains the crypto capabilities of the device.
- Provides functions to control the inline encryption hardware.
Originally these were just for programming/evicting keyslots;
however, new functionality (hardware-wrapped keys) will require new
functions here which are unrelated to keyslots. Moreover,
device-mapper devices already (ab)use "keyslot_evict" to pass key
eviction requests to their underlying devices even though
device-mapper devices don't have any keyslots themselves (so it
really should be "evict_key", not "keyslot_evict").
- Sometimes (but not always!) it manages keyslots. Originally it
always did, but device-mapper devices don't have keyslots
themselves, so they use a "passthrough keyslot manager" which
doesn't actually manage keyslots. This hack works, but the
terminology is unnatural. Also, some hardware doesn't have keyslots
and thus also uses a "passthrough keyslot manager" (support for such
hardware is yet to be upstreamed, but it will happen eventually).
Let's stop having keyslot managers which don't actually manage keyslots.
Instead, rename blk_keyslot_manager to blk_crypto_profile.
This is a fairly big change, since for consistency it also has to update
keyslot manager-related function names, variable names, and comments --
not just the actual struct name. However it's still a fairly
straightforward change, as it doesn't change any actual functionality.

The last user of this struct gone a couple of releases ago.
Besides that there were not so many users of this API for
more than 10 years:
1/ The one is Intel Merrifield, that had been added 2016-08-31
by the commit 3976b0380b ("x86/platform/intel-mid: Enable
SD card detection on Merrifield") and removed 2021-02-11 by
the commit 4590d98f5a ("sfi: Remove framework for deprecated

2/ The other is Intel Sunrisepoint related, that had been added
2015-02-06 by the commit e1bfad6d93 ("mmc: sdhci-pci: Add
support for drive strength selection for SPT") and removed
2017-03-20 by the commit 51ced59cc0 ("mmc: sdhci-pci: Use

Make 'struct mmc_request' contain a pointer to the request's
'struct bio_crypt_ctx' directly, instead of extracting a 32-bit DUN from
it which is a cqhci-crypto specific detail.
This keeps the cqhci crypto specific details in the cqhci module, and it
makes mmc_core and mmc_block ready for MMC crypto hardware that accepts
the DUN and/or key in a way that is more flexible than that which will
be specified by the eMMC v5.2 standard. Exynos SoCs are an example of
such hardware, as their inline encryption hardware takes keys directly
(it has no concept of keyslots) and supports 128-bit DUNs.
Note that the 32-bit DUN length specified by the standard is very
restrictive, so it is likely that more hardware will support longer DUNs
despite it not following the standard. Thus, limiting the scope of the
32-bit DUN assumption to the place that actually needs it is warranted.

In SD spec v6.x the SD function extension registers for performance
enhancements were introduced. As a part of this an optional internal cache
on the SD card, can be used to improve performance.
The let the SD card use the cache, the host needs to enable it and manage
flushing of the cache, so let's add support for this.
Note that for an SD card supporting the cache it's mandatory for it, to
also support the poweroff notification feature. According to the SD spec,
if the cache has been enabled and a poweroff notification is sent to the
card, that implicitly also means that the card should flush its internal
cache. Therefore, dealing with cache flushing for REQ_OP_FLUSH block
requests is sufficient.

Rather than only deselecting the SD card via a CMD7, before we cut power to
it at system suspend, at runtime suspend or at shutdown, let's add support
for a graceful power off sequence via enabling the SD Power Off
Notification feature.
Note that, the Power Off Notification feature was added in the SD spec
v4.x, which is several years ago. However, it's still a bit unclear how
often the SD card vendors decides to implement support for it. To validate
these changes a Sandisk Extreme PRO A2 64GB has been used, which seems to
work nicely.

In the SD spec v4.0 the CMD48/49 and CMD58/59 were introduced as optional
commands. In the SD spec v4.1 the SD function extension registers were
introduced, which requires support for CMD48/49/58/59 to be read/written
from/to.
Moreover, a specific function extension register were added to let the card
announce support for optional features in regards to power management. The
features that were added are "Power Off Notification", "Power Down Mode"
and "Power Sustenance".
As a first step to support this, let's read and parse the register for
power management during the SD card initialization and store the
information about the supported features in the struct mmc_card. In this
way, we prepare for subsequent changes to implement the complete support
for the new features.

The mmc core uses a PM notifier to temporarily during system suspend, turn
off the card detection mechanism for removal/insertion of (e)MMC/SD/SDIO
cards. Additionally, the notifier may be used to remove an SDIO card
entirely, if a corresponding SDIO functional driver don't have the system
suspend/resume callbacks assigned. This behaviour has been around for a
very long time.
However, a recent bug report tells us there are problems with this
approach. More precisely, when receiving the PM_SUSPEND_PREPARE
notification, we may end up hanging on I/O to be completed, thus also
preventing the system from getting suspended.
In the end what happens, is that the cancel_delayed_work_sync() in
mmc_pm_notify() ends up waiting for mmc_rescan() to complete - and since
mmc_rescan() wants to claim the host, it needs to wait for the I/O to be
completed first.
Typically, this problem is triggered in Android, if there is ongoing I/O
while the user decides to suspend, resume and then suspend the system
again. This due to that after the resume, an mmc_rescan() work gets punted
to the workqueue, which job is to verify that the card remains inserted
after the system has resumed.
To fix this problem, userspace needs to become frozen to suspend the I/O,
prior to turning off the card detection mechanism. Therefore, let's drop
the PM notifiers for mmc subsystem altogether and rely on the card
detection to be turned off/on as a part of the system_freezable_wq, that we
are already using.
Moreover, to allow and SDIO card to be removed during system suspend, let's
manage this from a ->prepare() callback, assigned at the mmc_host_class
level. In this way, we can use the parent device (the mmc_host_class
device), to remove the card device that is the child, in the
device_prepare() phase.
