f722e650d9 mmc: core: add support for disabling HS400 mode via DT
On some boards the data strobe line isn't wired up, rendering HS400
support broken, even if both the controller and the eMMC claim to
support it. Allow to disable HS400 mode via DT.

Instead of having an indirection through the SDHCI layer and emulating
a capability bit, that isn't there in hardware, do the same same thing
as with HS400_ES and advertise the support for HS400 directly through
the MMC caps.

4d895de350 dt-bindings: mmc: add no-mmc-hs400 flag
HS400 requires a data strobe line in addition to the usual MMC signal
lines. If a board design neglects to wire up this signal, HS400 mode is
not available, even if both the controller and the eMMC are claiming to
support this mode. Add a DT flag to allow boards to disable the HS400
support in this case.

130206a615 mmc: core: Add support for cache ctrl for SD cards
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.

70b52f0908 mmc: block: Disable CMDQ on the ioctl path
According to the eMMC Spec:
"When command queuing is enabled (CMDQ Mode En bit in CMDQ_MODE_EN
field is set to ‘1’) class 11 commands are the only method through
which data transfer tasks can be issued. Existing data transfer
commands, namely CMD18/CMD17 and CMD25/CMD24, are not supported when
command queuing is enabled."
which means if CMDQ is enabled, the FFU commands will not be supported.
To fix this issue, just simply disable CMDQ on the ioctl path, and
re-enable CMDQ once ioctl request is completed.

2c5d427690 mmc: core: Add support for Power Off Notification for SD cards
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.

c784f92769 mmc: core: Read the SD function extension registers for power management
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.

6fa79651cc mmc: core: Enable eMMC sleep commands to use HW busy polling
After the eMMC sleep command (CMD5) has been sent, the card start signals
busy on the DAT0 line, which can be monitored to understand when it's
allowed to proceed to power off the VCC regulator.

When MMC_CAP_WAIT_WHILE_BUSY isn't supported by the host the DAT0 line
isn't being monitored for busy completion, but instead we are waiting a
fixed period of time. The time corresponds to the sleep timeout that is
specified in the EXT_CSD register of the eMMC card. This is many cases
suboptimal, as the timeout corresponds to the worst case scenario.

To improve the situation add support for HW busy polling through the
->card_busy() host ops, when the host supports this.

More precisely, let __mmc_poll_for_busy() take a pointer to a callback
function as in-parameter, which it calls to poll for busy state completion.
Additionally, let's share __mmc_poll_for_busy() to allow it to be re-used
outside of mmc_ops.c. Subsequent changes will make use of it.

331a6edb30 SCSI fixes on 20210613
Four reasonably small fixes to the core for scsi host allocation
 failure paths.  The root problem is that we're not freeing the memory
 allocated by dev_set_name(), which involves a rejig of may of the free
 on error paths to do put_device() instead of kfree which, in turn, has
 several other knock on ramifications and inspection turned up a few
 other lurking bugs.

2e3025434a mm: relocate 'write_protect_seq' in struct mm_struct
0day robot reported a 9.2% regression for will-it-scale mmap1 test
case[1], caused by commit 57efa1fe59 ("mm/gup: prevent gup_fast from
racing with COW during fork").

Further debug shows the regression is due to that commit changes the
offset of hot fields 'mmap_lock' inside structure 'mm_struct', thus some
cache alignment changes.

From the perf data, the contention for 'mmap_lock' is very severe and
takes around 95% cpu cycles, and it is a rw_semaphore

        struct rw_semaphore {
                atomic_long_t count;	/* 8 bytes */
                atomic_long_t owner;	/* 8 bytes */
                struct optimistic_spin_queue osq; /* spinner MCS lock */
                ...

Before commit 57efa1fe59 adds the 'write_protect_seq', it happens to
have a very optimal cache alignment layout, as Linus explained:

 "and before the addition of the 'write_protect_seq' field, the
  mmap_sem was at offset 120 in 'struct mm_struct'.

  Which meant that count and owner were in two different cachelines,
  and then when you have contention and spend time in
  rwsem_down_write_slowpath(), this is probably *exactly* the kind
  of layout you want.

  Because first the rwsem_write_trylock() will do a cmpxchg on the
  first cacheline (for the optimistic fast-path), and then in the
  case of contention, rwsem_down_write_slowpath() will just access
  the second cacheline.

  Which is probably just optimal for a load that spends a lot of
  time contended - new waiters touch that first cacheline, and then
  they queue themselves up on the second cacheline."

After the commit, the rw_semaphore is at offset 128, which means the
'count' and 'owner' fields are now in the same cacheline, and causes
more cache bouncing.

Currently there are 3 "#ifdef CONFIG_XXX" before 'mmap_lock' which will
affect its offset:

  CONFIG_MMU
  CONFIG_MEMBARRIER
  CONFIG_HAVE_ARCH_COMPAT_MMAP_BASES

The layout above is on 64 bits system with 0day's default kernel config
(similar to RHEL-8.3's config), in which all these 3 options are 'y'.
And the layout can vary with different kernel configs.

Relayouting a structure is usually a double-edged sword, as sometimes it
can helps one case, but hurt other cases.  For this case, one solution
is, as the newly added 'write_protect_seq' is a 4 bytes long seqcount_t
(when CONFIG_DEBUG_LOCK_ALLOC=n), placing it into an existing 4 bytes
hole in 'mm_struct' will not change other fields' alignment, while
restoring the regression.

43cb5d49a9 USB fixes for 5.13-rc6
Here are a number of tiny USB fixes for 5.13-rc6.
 
 There are more than I would normally like, but there's been a bunch of
 people banging on the gadget and dwc3 and typec code recently for I
 think an Android release, which has resulted in a number of small fixes.
 It's nice to see companies send fixes upstream for this type of work, a
 notable change from years ago.
 
 Anyway, fixes in here are:
 	- usb-serial device id updates
 	- usb-serial cp210x driver fixes for broken firmware versions
 	- typec fixes for crazy charging devices and other reported
 	  problems
 	- dwc3 fixes for reported problems found
 	- gadget fixes for reported problems
 	- tiny xhci fixes
 	- other small fixes for reported issues.
 	- revert of a problem fix found by linux-next testing
 
 All of these have passed 0-day and linux-next testing with no reported
 problems (the revert for the found linux-next build problem included).
