After some investigation, I think I found the root cause: commit
2bfc6cd81bd ("move kernel mapping outside of linear mapping") moves
BPF JIT region after the kernel:
| #define BPF_JIT_REGION_START PFN_ALIGN((unsigned long)&_end)
The &_end is unlikely aligned with PMD size, so the front bpf jit
region sits with part of kernel .data section in one PMD size mapping.
But kernel is mapped in PMD SIZE, when bpf_jit_binary_lock_ro() is
called to make the first bpf jit prog ROX, we will make part of kernel
.data section RO too, so when we write to, for example memset the
.data section, MMU will trigger a store page fault.
To fix the issue, we need to ensure the BPF JIT region is PMD size
aligned. This patch acchieve this goal by restoring the BPF JIT region
to original position, I.E the 128MB before kernel .text section. The
modification to kasan_init.c is inspired by Alexandre.

Patch series "Actually fix freelist pointer vs redzoning", v4.
This fixes redzoning vs the freelist pointer (both for middle-position
and very small caches). Both are "theoretical" fixes, in that I see no
evidence of such small-sized caches actually be used in the kernel, but
that's no reason to let the bugs continue to exist, especially since
people doing local development keep tripping over it. :)
This patch (of 3):
Instead of repeating "Redzone" and "Poison", clarify which sides of
those zones got tripped. Additionally fix column alignment in the
trailer.
Before:
BUG test (Tainted: G B ): Redzone overwritten
...
Redzone (____ptrval____): bb bb bb bb bb bb bb bb ........

After:
BUG test (Tainted: G B ): Right Redzone overwritten

When computing the access permissions of a shadow page, use the effective
permissions of the walk up to that point, i.e. the logic AND of its parents'
permissions. Two guest PxE entries that point at the same table gfn need to
be shadowed with different shadow pages if their parents' permissions are
different. KVM currently uses the effective permissions of the last
non-leaf entry for all non-leaf entries. Because all non-leaf SPTEs have
full ("uwx") permissions, and the effective permissions are recorded only
in role.access and merged into the leaves, this can lead to incorrect
reuse of a shadow page and eventually to a missing guest protection page
fault.
For example, here is a shared pagetable:
pgd[] pud[] pmd[] virtual address pointers
/->pmd1(u--)->pte1(uw-)->page1 <- ptr1 (u--)
/->pud1(uw-)--->pmd2(uw-)->pte2(uw-)->page2 <- ptr2 (uw-)
pgd-| (shared pmd[] as above)
\->pud2(u--)--->pmd1(u--)->pte1(uw-)->page1 <- ptr3 (u--)
\->pmd2(uw-)->pte2(uw-)->page2 <- ptr4 (u--)
pud1 and pud2 point to the same pmd table, so:
- ptr1 and ptr3 points to the same page.
- ptr2 and ptr4 points to the same page.
(pud1 and pud2 here are pud entries, while pmd1 and pmd2 here are pmd entries)
- First, the guest reads from ptr1 first and KVM prepares a shadow
page table with role.access=u--, from ptr1's pud1 and ptr1's pmd1.
"u--" comes from the effective permissions of pgd, pud1 and
pmd1, which are stored in pt->access. "u--" is used also to get
the pagetable for pud1, instead of "uw-".
- Then the guest writes to ptr2 and KVM reuses pud1 which is present.
The hypervisor set up a shadow page for ptr2 with pt->access is "uw-"
even though the pud1 pmd (because of the incorrect argument to
kvm_mmu_get_page in the previous step) has role.access="u--".
- Then the guest reads from ptr3. The hypervisor reuses pud1's
shadow pmd for pud2, because both use "u--" for their permissions.
Thus, the shadow pmd already includes entries for both pmd1 and pmd2.
- At last, the guest writes to ptr4. This causes no vmexit or pagefault,
because pud1's shadow page structures included an "uw-" page even though
its role.access was "u--".
Any kind of shared pagetable might have the similar problem when in
virtual machine without TDP enabled if the permissions are different
from different ancestors.
In order to fix the problem, we change pt->access to be an array, and
any access in it will not include permissions ANDed from child ptes.
The test code is: https://lore.kernel.org/kvm/20210603050537.19605-1-jiangshanlai@gmail.com/
Remember to test it with TDP disabled.
The problem had existed long before the commit 41074d07c78b ("KVM: MMU:
Fix inherited permissions for emulated guest pte updates"), and it
is hard to find which is the culprit. So there is no fixes tag here.

There is a fair amount of warnings when running 'make dtbs_check' with

arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0: [66, 0, 0] is too long
The reason is that the sound-dai phandle provided has cells, and in such
case the schema should use 'phandle-array' instead of 'phandle'.

At the moment, the edt-ft5x06 driver can control a single regulator
("vcc"). However, some FocalTech touch controllers have an additional
IOVCC pin that should be supplied with the digital I/O voltage.
The I/O voltage might be provided by another regulator that should also
be kept on. Otherwise, the touchscreen can randomly stop functioning if
the regulator is turned off because no other components still require it.
Document (optional) support for controlling the regulator for IOVCC
using "iovcc-supply".

This converts the CYTTSP "Cypress TrueTouch Standard Product"
to YAML bindings and fixes and adds some things in the process:
- Rename the bindings file to cypress,cy8ctma340 after the main
product in the series.
- Add proper compatibles for the two known products:
CY8CTMA340 and CY8CTST341.
- Deprecate "cypress,cyttsp-spi" and "cypress,cyttsp-i2c"
because device compatibles should be named after the
hardware and not after which bus they are connected to.
The topology implicitly tells us which bus it is and what
interface to used.
- Add VCPIN and VDD supplies, these are present just like
on the CY8CTMA140.
