msm-fixes for v6.4-rc3
Display Fixes:
+ Catalog fixes:
- fix the programmable fetch lines and qos settings of msm8998
to match what is present downstream
- fix the LM pairs for msm8998 to match what is present downstream.
The current settings are not right as LMs with incompatible
connected blocks are paired
- remove unused INTF0 interrupt mask from SM6115/QCM2290 as there
is no INTF0 present on those chipsets. There is only one DSI on
index 1
- remove TE2 block from relevant chipsets because this is mainly
used for ping-pong split feature which is not supported upstream
and also for the chipsets where we are removing them in this
change, that block is not present as the tear check has been moved
to the intf block
- relocate non-MDP_TOP INTF_INTR offsets from dpu_hwio.h to
dpu_hw_interrupts.c to match where they belong
- fix the indentation for REV_7xxx interrupt masks
- fix the offset and version for dither blocks of SM8[34]50/SC8280XP
chipsets as it was incorrect
- make the ping-pong blk length 0 for appropriate chipsets as those
chipsets only have a dither ping-pong dither block but no other
functionality in the base ping-pong
- remove some duplicate register defines from INTF
+ Fix the log mask for the writeback block so that it can be enabled
correctly via debugfs
+ unregister the hdmi codec for dp during unbind otherwise it leaks
audio codec devices
+ Yaml change to fix warnings related to 'qcom,master-dsi' and
'qcom,sync-dual-dsi'
GPU Fixes:
+ fix submit error path leak
+ arm-smmu-qcom fix for regression that broke per-process page tables
+ fix no-iommu crash

This code was written prior to previous updates to this
logic for other chips. The RSC registers are part of
SMUIO which is an always on block so there is no need
to disable gfxoff. Additionally add the carryover and
preemption checks.

Normally the extended attributes in the inode body would have been
checked when the inode is first opened, but if someone is writing to
the block device while the file system is mounted, it's possible for
the inode table to get corrupted. Add bounds checking to avoid
reading beyond the end of allocated memory if this happens.

Whether the file system is mounted read-only or read/write is more
important than the quota mode, which we are already printing. Add the
ro vs r/w indication since this can be helpful in debugging problems
from the console log.

If there are failures while changing the mount options in
__ext4_remount(), we need to restore the old mount options.
This commit fixes two problem. The first is there is a chance that we
will free the old quota file names before a potential failure leading
to a use-after-free. The second problem addressed in this commit is
if there is a failed read/write to read-only transition, if the quota
has already been suspended, we need to renable quota handling.

Ext4 has a filesystem wide lock protecting ext4_writepages() calls to
avoid races with switching of journalled data flag or inode format. This
lock can however cause a deadlock like:
CPU0 CPU1
ext4_writepages()
percpu_down_read(sbi->s_writepages_rwsem);
ext4_change_inode_journal_flag()
percpu_down_write(sbi->s_writepages_rwsem);
- blocks, all readers block from now on
ext4_do_writepages()
ext4_init_io_end()
kmem_cache_zalloc(io_end_cachep, GFP_KERNEL)
fs_reclaim frees dentry...
dentry_unlink_inode()
iput() - last ref =>
iput_final() - inode dirty =>
write_inode_now()...
ext4_writepages() tries to acquire sbi->s_writepages_rwsem
and blocks forever
Make sure we cannot recurse into filesystem reclaim from writeback code
to avoid the deadlock.

Previously, ext4_get_group_info() would treat an invalid group number
as BUG(), since in theory it should never happen. However, if a
malicious attaker (or fuzzer) modifies the superblock via the block
device while it is the file system is mounted, it is possible for
s_first_data_block to get set to a very large number. In that case,
when calculating the block group of some block number (such as the
starting block of a preallocation region), could result in an
underflow and very large block group number. Then the BUG_ON check in
ext4_get_group_info() would fire, resutling in a denial of service
attack that can be triggered by root or someone with write access to
the block device.
For a quality of implementation perspective, it's best that even if
the system administrator does something that they shouldn't, that it
will not trigger a BUG. So instead of BUG'ing, ext4_get_group_info()
will call ext4_error and return NULL. We also add fallback code in
all of the callers of ext4_get_group_info() that it might NULL.
Also, since ext4_get_group_info() was already borderline to be an
inline function, un-inline it. The results in a next reduction of the
compiled text size of ext4 by roughly 2k.
