I have a handful of fixes that I'd like to target for 5.12, regardless
of whether there's an rc8 or not:
* A fix to properly select SPARSEMEM_STATIC on rv32.
* A handful of fixes to kprobes.
I don't generally like sending stuff this late, but these all seem
pretty safe.

After commit 2decad92f4 ("arm64: mte: Ensure TIF_MTE_ASYNC_FAULT is
set atomically"), LLVM's integrated assembler fails to build entry.S:
<instantiation>:5:7: error: expected assembly-time absolute expression
.org . - (664b-663b) + (662b-661b)
^
<instantiation>:6:7: error: expected assembly-time absolute expression
.org . - (662b-661b) + (664b-663b)
^
The root cause is LLVM's assembler has a one-pass design, meaning it
cannot figure out these instruction lengths when the .org directive is
outside of the subsection that they are in, which was changed by the
.arch_extension directive added in the above commit.
Apply the same fix from commit 966a0acce2 ("arm64/alternatives: move
length validation inside the subsection") to the alternative_endif
macro, shuffling the .org directives so that the length validation
happen will always happen in the same subsections. alternative_insn has
not shown any issue yet but it appears that it could have the same issue
in the future so just preemptively change it.

dm verity fec: fix misaligned RS roots IO
commit df7b59ba92 ("dm verity: fix FEC for RS roots unaligned to
block size") introduced the possibility for misaligned roots IO
relative to the underlying device's logical block size. E.g. Android's
default RS roots=2 results in dm_bufio->block_size=1024, which causes
the following EIO if the logical block size of the device is 4096,
given v->data_dev_block_bits=12:
E sd 0 : 0:0:0: [sda] tag#30 request not aligned to the logical block size
E blk_update_request: I/O error, dev sda, sector 10368424 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0
E device-mapper: verity-fec: 254:8: FEC 9244672: parity read failed (block 18056): -5
Fix this by onlu using f->roots for dm_bufio blocksize IFF it is
aligned to v->data_dev_block_bits.

If instruction being single stepped caused a page fault, the kprobes
is cancelled to let the page fault handler continue as a normal page
fault. But the local irqflags are disabled so cpu will restore pstate
with DAIF masked. After pagefault is serviced, the kprobes is
triggerred again, we overwrite the saved_irqflag by calling
kprobes_save_local_irqflag(). NOTE, DAIF is masked in this new saved
irqflag. After kprobes is serviced, the cpu pstate is retored with
DAIF masked.

After the recently added commit fe0f1e3bfd ("drm/i915: Shut down
displays gracefully on reboot"), the DSI panel on a Cherry Trail based
Predia Basic tablet would no longer properly light up after reboot.
I've managed to reproduce this without rebooting by doing:
chvt 3; echo 1 > /sys/class/graphics/fb0/blank;\
echo 0 > /sys/class/graphics/fb0/blank
Which rapidly turns the panel off and back on again.
The vlv_dsi.c code uses an intel_dsi_msleep() helper for the various delays
used for panel on/off, since starting with MIPI-sequences version >= 3 the
delays are already included inside the MIPI-sequences.
The problems exposed by the "Shut down displays gracefully on reboot"
change, show that using this helper for the panel_pwr_cycle_delay is
not the right thing to do. This has not been noticed until now because
normally the panel never is cycled off and directly on again in quick
succession.
Change the msleep for the panel_pwr_cycle_delay to a normal msleep()
call to avoid the panel staying black after a quick off + on cycle.

This leads to allocating no DDB for the Y plane since .min_ddb_alloc

Looks like that there actually are another subset of laptops on the market
that don't support the Intel HDR backlight interface, but do advertise
support for the VESA DPCD backlight interface despite the fact it doesn't
seem to work.
Note though I'm not entirely clear on this - on one of the machines where
this issue was observed, I also noticed that we appeared to be rejecting
the VBT defined backlight frequency in
intel_dp_aux_vesa_calc_max_backlight(). It's noted in this function that:
/* Use highest possible value of Pn for more granularity of brightness
* adjustment while satifying the conditions below.
* ...
* - FxP is within 25% of desired value.
* Note: 25% is arbitrary value and may need some tweak.
*/
So it's possible that this value might just need to be tweaked, but for now
let's just disable the VESA backlight interface unless it's specified in
the VBT just to be safe. We might be able to try enabling this again by
default in the future.

Currently psw_idle does not allocate a stack frame and does not
save its r14 and r15 into the save area. Even though this is valid from
call ABI point of view, because psw_idle does not make any calls
explicitly, in reality psw_idle is an entry point for controlled
transition into serving interrupts. So, in practice, psw_idle stack
frame is analyzed during stack unwinding. Depending on build options
that r14 slot in the save area of psw_idle might either contain a value
saved by previous sibling call or complete garbage.

Currently when interrupt arrives to cpu while in kernel context
INT_HANDLER macro (used for ext_int_handler and io_int_handler)
allocates new stack frame and pt_regs on the kernel stack and
sets up the backchain to jump over the pt_regs to the frame which has
been interrupted. This is not ideal to two reasons:
1. This hides the fact that kernel stack contains interrupt frame in it
and hence breaks arch_stack_walk_reliable(), which needs to know that to
guarantee "reliability" and checks that there are no pt_regs on the way.
2. It breaks the backchain unwinder logic, which assumes that the next
stack frame after an interrupt frame is reliable, while it is not.
In some cases (when r14 contains garbage) this leads to early unwinding
termination with an error, instead of marking frame as unreliable
and continuing.
To address that, only set backchain to 0.

In the first list_for_each_entry() macro of dma_async_device_register,
it gets the chan from list and calls __dma_async_device_channel_register
(..,chan). We can see that chan->local is allocated by alloc_percpu() and
it is freed chan->local by free_percpu(chan->local) when
__dma_async_device_channel_register() failed.
But after __dma_async_device_channel_register() failed, the caller will
goto err_out and freed the chan->local in the second time by free_percpu().
The cause of this problem is forget to set chan->local to NULL when
chan->local was freed in __dma_async_device_channel_register(). My
patch sets chan->local to NULL when the callee failed to avoid double free.

Pull btrfs fix from David Sterba:
"One more patch that we'd like to get to 5.12 before release.
It's changing where and how the superblock is stored in the zoned
mode. It is an on-disk format change but so far there are no
implications for users as the proper mkfs support hasn't been merged
and is waiting for the kernel side to settle.
Until now, the superblocks were derived from the zone index, but zone
size can differ per device. This is changed to be based on fixed
offset values, to make it independent of the device zone size.
The work on that got a bit delayed, we discussed the exact locations
to support potential device sizes and usecases. (Partially delayed
also due to my vacation.) Having that in the same release where the
zoned mode is declared usable is highly desired, there are userspace
projects that need to be updated to recognize the feature. Pushing
that to the next release would make things harder to test"

Pull percpu fix from Dennis Zhou:
"This contains a fix for sporadically failing atomic percpu
allocations.
I only caught it recently while I was reviewing a new series [1] and
simultaneously saw reports by btrfs in xfstests [2] and [3].
In v5.9, memcg accounting was extended to percpu done by adding a
second type of chunk. I missed an interaction with the free page float
count used to ensure we can support atomic allocations. If one type of
chunk has no free pages, but the other has enough to satisfy the free
page float requirement, we will not repopulate the free pages for the
former type of chunk. This led to the sporadically failing atomic
allocations"
