[ Upstream commit 6eefaee4f2d366a389da0eb95e524ba82bf358c4 ]
With a couple allies at Intel, and much badgering, I got confirmation
from Intel that at least BXT suffers from the same SPI chip-select
issue as Cannonlake (and beyond). The issue being that after going
through runtime suspend/resume, toggling the chip-select line without
also sending data does nothing.
Add the quirk to BXT to briefly toggle dynamic clock gating off and
on, forcing the fabric to wake up enough to notice the CS register
change.

Prior to commit 8eb7e28d4c ("arm64/mm: move runtime pgds to
rodata"), idmap_pgd_dir, tramp_pg_dir, reserved_ttbr0, swapper_pg_dir,
and init_pg_dir were contiguous at the end of the kernel image. The
maintenance at the end of __create_page_tables assumed these were
contiguous, and affected everything from the start of idmap_pg_dir
to the end of init_pg_dir.
That commit moved all but init_pg_dir into the .rodata section, with
other data placed between idmap_pg_dir and init_pg_dir, but did not
update the maintenance. Hence the maintenance is performed on much
more data than necessary (but as the bootloader previously made this
clean to the PoC there is no functional problem).
As we only alter idmap_pg_dir, and init_pg_dir, we only need to perform
maintenance for these. As the other dirs are in .rodata, the bootloader
will have initialised them as expected and cleaned them to the PoC. The
kernel will initialize them as necessary after enabling the MMU.
This patch reworks the maintenance to only cover the idmap_pg_dir and
init_pg_dir to avoid this unnecessary work.

The subdev set pad format operation currently misbehaves in multiple ways:
- mipi_csis_try_format() unconditionally stores the format in the device
state, even for V4L2_SUBDEV_FORMAT_TRY.
- The format is never stored in the pad cfg, but the pad cfg format
always overwrites the format requested by the user.
- The sink format is not propagated to the source.
Fix all this by reworking the set format operation as follows:
1. For the source pad, turn set() into get() as the source format is not
modifiable.
2. Validate the requested format and updated the stored format
accordingly.
3. Return the format actually set.
4. Propagate the format from sink to source.

Also, fix stackoverflow issue seen after propagating above changes.
Console TX is getting stuck in recursive call and leading to
stackoverflow issue.
Steps that leads to bad recursion call:
1) msm_geni_serial_handle_tx calls for stop_tx if all the data are sent and
acknowledged.
2) stop_tx issue cancel command if the main sequencer is still
active.
3) As part of cancel command execution msm_geni_serial_handle_tx is called
again that takes us to step 1 and goes in a loop.
To fix above scenario remove the stop_tx call from geni_serial_handle_tx
because if the data is transmited and acknowledged main sequencer should
automatically go to inactive state.
Ideally we should never enter into this situation the first place because
after receiving CMD_DONE we expect that sequencer will go IDLE/inactive.
So, probably this can be a race btw updation of CMD_DONE and GENI_STATUS
register because after adding some more IPC logs in the above code path we
are not hitting this issue. It might be adding required delay.

The only use of I_DIRTY_TIME_EXPIRE is to detect in
__writeback_single_inode() that inode got there because flush worker
decided it's time to writeback the dirty inode time stamps (either
because we are syncing or because of age). However we can detect this
directly in __writeback_single_inode() and there's no need for the
strange propagation with I_DIRTY_TIME_EXPIRE flag.

When we are processing writeback for sync(2), move_expired_inodes()
didn't set any inode expiry value (older_than_this). This can result in
writeback never completing if there's steady stream of inodes added to
b_dirty_time list as writeback rechecks dirty lists after each writeback
round whether there's more work to be done. Fix the problem by using
sync(2) start time is inode expiry value when processing b_dirty_time
list similarly as for ordinarily dirtied inodes. This requires some
refactoring of older_than_this handling which simplifies the code
noticeably as a bonus.

Inode's i_io_list list head is used to attach inode to several different
lists - wb->{b_dirty, b_dirty_time, b_io, b_more_io}. When flush worker
prepares a list of inodes to writeback e.g. for sync(2), it moves inodes
to b_io list. Thus it is critical for sync(2) data integrity guarantees
that inode is not requeued to any other writeback list when inode is
queued for processing by flush worker. That's the reason why
writeback_single_inode() does not touch i_io_list (unless the inode is
completely clean) and why __mark_inode_dirty() does not touch i_io_list
if I_SYNC flag is set.
However there are two flaws in the current logic:
1) When inode has only I_DIRTY_TIME set but it is already queued in b_io
list due to sync(2), concurrent __mark_inode_dirty(inode, I_DIRTY_SYNC)
can still move inode back to b_dirty list resulting in skipping
writeback of inode time stamps during sync(2).
2) When inode is on b_dirty_time list and writeback_single_inode() races
with __mark_inode_dirty() like:
writeback_single_inode() __mark_inode_dirty(inode, I_DIRTY_PAGES)
inode->i_state |= I_SYNC
__writeback_single_inode()
inode->i_state |= I_DIRTY_PAGES;
if (inode->i_state & I_SYNC)
bail
if (!(inode->i_state & I_DIRTY_ALL))
- not true so nothing done
We end up with I_DIRTY_PAGES inode on b_dirty_time list and thus
standard background writeback will not writeback this inode leading to
possible dirty throttling stalls etc. (thanks to Martijn Coenen for this
analysis).
Fix these problems by tracking whether inode is queued in b_io or
b_more_io lists in a new I_SYNC_QUEUED flag. When this flag is set, we
know flush worker has queued inode and we should not touch i_io_list.
On the other hand we also know that once flush worker is done with the
inode it will requeue the inode to appropriate dirty list. When
I_SYNC_QUEUED is not set, __mark_inode_dirty() can (and must) move inode
to appropriate dirty list.
