[ Upstream commit a53936361330e4c55c0654605178281387d9c761 ]
Commit 3c6c2bebef ("f2fs: avoid punch_hole overhead when releasing
volatile data") introduced FI_FIRST_BLOCK_WRITTEN as below reason:
This patch is to avoid some punch_hole overhead when releasing volatile
data. If volatile data was not written yet, we just can make the first
page as zero.
After commit 7bc155fec5 ("f2fs: kill volatile write support"), we
won't support volatile write, but it missed to remove obsolete
FI_FIRST_BLOCK_WRITTEN, delete it in this patch.

This seems to be because an event handler is registered before the

Instead, only register the event handler after srpt device initialization

Realtek codec on HP Envy laptop series are heavily modified by vendor.
Therefore, need intervention to make it work properly. The patch fixes:
- B&O soundbar speakers (between lid and keyboard) activation
- Enable LED on mute button
- Add missing process coefficient which affects the output amplifier
- Volume control synchronization between B&O soundbar and side speakers
- Unmute headset output on several HP Envy models
- Auto-enable headset mic when plugged
This patch was tested on HP Envy x360 13-AR0107AU with Realtek ALC285
The only unsolved problem is output amplifier of all built-in speakers
is too weak, which causes volume of built-in speakers cannot be loud
as vendor's proprietary driver due to missing _DSD parameter in the
firmware. The solution is currently on research. Expected to has another
patch in the future.

cifs writeback doesn't correctly handle the case where
cifs_extend_writeback() hits a point where it is considering an additional
folio, but this would overrun the wsize - at which point it drops out of
the xarray scanning loop and calls xas_pause(). The problem is that
xas_pause() advances the loop counter - thereby skipping that page.
What needs to happen is for xas_reset() to be called any time we decide we
don't want to process the page we're looking at, but rather send the
request we are building and start a new one.
Fix this by copying and adapting the netfslib writepages code as a
temporary measure, with cifs writeback intending to be offloaded to
netfslib in the near future.
This also fixes the issue with the use of filemap_get_folios_tag() causing
retry of a bunch of pages which the extender already dealt with.
This can be tested by creating, say, a 64K file somewhere not on cifs
(otherwise copy-offload may get underfoot), mounting a cifs share with a
wsize of 64000, copying the file to it and then comparing the original file
and the copy:
dd if=/dev/urandom of=/tmp/64K bs=64k count=1
mount //192.168.6.1/test /mnt -o user=...,pass=...,wsize=64000
cp /tmp/64K /mnt/64K
cmp /tmp/64K /mnt/64K
Without the fix, the cmp fails at position 64000 (or shortly thereafter).

The synchronization here is to ensure the ordering of freeing of a module
init so that it happens before W+X checking. It is worth noting it is not
that the freeing was not happening, it is just that our sanity checkers
raced against the permission checkers which assume init memory is already
gone.
Commit 1a7b7d9220 ("modules: Use vmalloc special flag") moved calling
do_free_init() into a global workqueue instead of relying on it being
called through call_rcu(..., do_free_init), which used to allowed us call
do_free_init() asynchronously after the end of a subsequent grace period.
The move to a global workqueue broke the gaurantees for code which needed
to be sure the do_free_init() would complete with rcu_barrier(). To fix
this callers which used to rely on rcu_barrier() must now instead use
flush_work(&init_free_wq).
Without this fix, we still could encounter false positive reports in W+X
checking since the rcu_barrier() here can not ensure the ordering now.
Even worse, the rcu_barrier() can introduce significant delay. Eric
Chanudet reported that the rcu_barrier introduces ~0.1s delay on a
PREEMPT_RT kernel.

The current register offset used for the GCC_UBI0_AXI_ARES reset
seems wrong. Or at least, the downstream driver uses [1] the same
offset which is used for other the GCC_UBI0_*_ARES resets.
Change the code to use the same offset used in the downstream
driver and also specify the reset bit explicitly to use the
same format as the followup entries.

The following table shows the values of the 'halt_reg' and the
'enable_reg' fields from the pcie clocks defined in the current
driver:
clock halt_reg enable_reg
gcc_pcie0_ahb_clk 0x75010 0x75010
gcc_pcie0_aux_clk 0x75014 0x75014

gcc_pcie1_axi_s_clk 0x7600c 0x7600c
gcc_pcie1_pipe_clk 8* 0x76018
Based on the table, it is quite likely that the pcie0 and the pci1
clocks are using the same register layout, however it seems that
the value of the 'halt_reg' field in the 'gcc_pcie1_pipe_clk' clock
is wrong.
In the downstream driver [1], the same '0x76018' value is used for
both the 'halt_reg' and for the 'enable_reg' fields of the
'gcc_pcie1_pipe_clk' clock.
Update the current driver to use the same value used downstream as
probably that is the correct value.

[ Upstream commit f982adcc1b1c02a3114f68ac73c811cbfabe90fa ]
The value of the 'enable_reg' field in the 'gcc_gmac0_sys_clk'
clock definition seems wrong as it is greater than the
'max_register' value defined in the regmap configuration.
Additionally, all other gmac specific branch clock definitions
within the driver uses the same value both for the 'enable_reg'
and for the 'halt_reg' fields.
Due to the lack of documentation the correct value is not known.
Looking into the downstream driver does not help either, as that
uses the same (presumably wrong) value [1].
Nevertheless, change the 'enable_reg' field of 'gcc_gmac0_sys_clk'
to use the value from the 'halt_reg' field so it follows the pattern
used in other gmac clock definitions. The change is based on the
assumption that the register layout of this clock is the same
as the other gmac clocks.

The above error is because of the hcall failure as required

have other reasons for hcall failures like H_AUTHORITY/H_PARAMETER with

It's possible that mtk_crtc->event is NULL in
mtk_drm_crtc_finish_page_flip().
pending_needs_vblank value is set by mtk_crtc->event, but in
mtk_drm_crtc_atomic_flush(), it's is not guarded by the same
lock in mtk_drm_finish_page_flip(), thus a race condition happens.
Consider the following case:
CPU1 CPU2
step 1:
mtk_drm_crtc_atomic_begin()
mtk_crtc->event is not null,
step 1:
mtk_drm_crtc_atomic_flush:
mtk_drm_crtc_update_config(
!!mtk_crtc->event)
step 2:
mtk_crtc_ddp_irq ->
mtk_drm_finish_page_flip:
lock
mtk_crtc->event set to null,
pending_needs_vblank set to false
unlock
pending_needs_vblank set to true,
step 2:
mtk_crtc_ddp_irq ->
mtk_drm_finish_page_flip called again,
pending_needs_vblank is still true
//null pointer
Instead of guarding the entire mtk_drm_crtc_atomic_flush(), it's more
efficient to just check if mtk_crtc->event is null before use.

Previously, the statement looked like:
slpm[x] &= ~BIT(g->grp.pins[i]);
Where:
- slpm is a unsigned int pointer;
- g->grp.pins[i] is a pin number. It can grow to more than 32.
The expected shift amount is a pin bank offset.
This bug does not occur on every group or pin: the altsetting must be
NMK_GPIO_ALT_C and the pin must be 32 or above. It might have occured.
For example, in pinctrl-nomadik-db8500.c, pin group i2c3_c_2 has the

Per commit b3f11af9b2 ("arm64: ftrace: forbid CALL_OPS with
CC_OPTIMIZE_FOR_SIZE"), GCC is silently ignoring `-falign-functions=N`
when passed `-Os`, causing functions to be improperly aligned. This
doesn't seem to be a problem with Clang though, where enabling CALL_OPS
with CC_OPTIMIZE_FOR_SIZE doesn't spit out any warnings at boot about
misaligned patch-sites. Only forbid CALL_OPS if GCC is used and we're
optimizing for size so that CALL_OPS can be used with clang optimizing
for size.
