One fix for the MMC card detect on the Pine H64 board

  arm64: dts: allwinner: Revert SD card CD GPIO for Pine64-LTS

Link: https://lore.kernel.org/r/45fc5e4d-ef48-4729-a869-79a8f288bb83.lettre@localhostSigned-off-by: NArnd Bergmann <arnd@arndb.de>

Commit 941432d0 ("arm64: dts: allwinner: Drop non-removable from
SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module,
along the way with the Pine64-LTS, which share the same base .dtsi.

This was based on the observation that the Pine64-LTS has as "push-push"
SD card socket, and that the schematic mentions the card detect GPIO.

After having received two reports about failing SD card access with that
patch, some more research and polls on that subject revealed that there
are at least two different versions of the Pine64-LTS out there:
- On some boards (including mine) the card detect pin is "stuck" at
  high, regardless of an microSD card being inserted or not.
- On other boards the card-detect is working, but is active-high, by
  virtue of an explicit inverter circuit, as shown in the schematic.

To cover all versions of the board out there, and don't take any chances,
let's revert the introduction of the active-low CD GPIO, but let's use
the broken-cd property for the Pine64-LTS this time. That should avoid
regressions and should work for everyone, even allowing SD card changes
now.
The SOPine card detect has proven to be working, so let's keep that
GPIO in place.

Fixes for omaps for v5.12-rc cycle

Fix swapped mmc device order also for omap3 that got changed with the
recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the aliases
should be board specific, all the mmc device instances are all there in
the SoC, and we do probe them by default so that PM runtime can idle the

Although every Beelink GS1 seems to have external 32768 Hz oscillator,
it works only on one from four tested. There are more reports of RTC
issues elsewhere, like Armbian forum.

One Beelink GS1 owner read RTC osc status register on Android which
shipped with the box. Reported value indicated problems with external
oscillator.

In order to fix RTC and related issues (HDMI-CEC and suspend/resume with
Crust) on all boards, switch to internal oscillator.

Commit 941432d0 ("arm64: dts: allwinner: Drop non-removable from
SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module,
along the way with the Pine64-LTS, which share the same base .dtsi.

However while both boards indeed have a working CD GPIO on PF6, the
polarity is different: the SOPine modules uses a "push-pull" socket,
which has an active-high switch, while the Pine64-LTS use the more
traditional push-push socket and the common active-low switch.

Fix the polarity in the sopine.dtsi, and overwrite it in the LTS
board .dts, to make the SD card work again on systems using SOPine
modules.

For each device, the nosy driver allocates a pcilynx structure.
A use-after-free might happen in the following scenario:

 1. Open nosy device for the first time and call ioctl with command
    NOSY_IOC_START, then a new client A will be malloced and added to
    doubly linked list.
 2. Open nosy device for the second time and call ioctl with command
    NOSY_IOC_START, then a new client B will be malloced and added to
    doubly linked list.
 3. Call ioctl with command NOSY_IOC_START for client A, then client A
    will be readded to the doubly linked list. Now the doubly linked
    list is messed up.
 4. Close the first nosy device and nosy_release will be called. In
    nosy_release, client A will be unlinked and freed.
 5. Close the second nosy device, and client A will be referenced,
    resulting in UAF.

The root cause of this bug is that the element in the doubly linked list
is reentered into the list.

Fix this bug by adding a check before inserting a client.  If a client
is already in the linked list, don't insert it.

The following KASAN report reveals it:

  something other than 8 (user space knows how to handle this), the 8
  extra words was not accounted for when reserving the event on the ring
  buffer, and added 8 more entries, due to the calculation of
  "sizeof(*entry) + nr_entries * sizeof(long)", as the sizeof(*entry)
  now contains 8 entries.

  The size of the caller field needs to be subtracted from the size of
  the entry to create the correct allocation size"

It's non-obvious how retry is done for block backed files, when it happens
off the kiocb done path. It also makes it tricky to deal with the iov_iter
handling.

Just mark the req as needing a reissue, and handling it from the
submission path instead. This makes it directly obvious that we're not
re-importing the iovec from userspace past the submit point, and it means
that we can just reuse our usual -EAGAIN retry path from the read/write
handling.

At some point in the future, we'll gain the ability to always reliably
return -EAGAIN through the stack. A previous attempt on the block side
didn't pan out and got reverted, hence the need to check for this
information out-of-band right now.

If IOCB_NOWAIT is set on submission, then that needs to get propagated to
REQ_NOWAIT on the block side. Otherwise we completely lose this
information, and any issuer of IOCB_NOWAIT IO will potentially end up
blocking on eg request allocation on the storage side.

In RV64, the size of each entry in excp_vect_table is 8 bytes. If the
base of the table is not 8-byte aligned, loading an entry in the table
will raise a misaligned exception. Although such exception will be
handled by opensbi/bbl, this still causes performance degradation.
