Many Colibri carrier boards are using 3.3V pull-up resistors on the
SD-Card connector. Letting it switch to 1.8V is an invalid state.
Do prevent this from happening by keeping the signaling voltage at 3.3V.

They're still in the operating range according to i.MX 8M Quad
datasheet. There's some headroom added over minimal values to
account for voltage drop.
Operational ranges (min - typ - max [selected]):
- VDD_SOC (BUCK1): 0.81 - 0.9 - 0.99 [0.88]
- VDD_ARM (BUCK2): 0.81 - 0.9 - 1.05 [0.84] (1000MHz)
0.90 - 1.0 - 1.05 [0.93] (1500MHz)
- VDD_GPU (BUCK3): 0.81 - 0.9 - 1.05 [0.85] (800MHz)
0.90 - 1.0 - 1.05 [ -- ] (1000MHz)
- VDD_VPU (BUCK4): 0.81 - 0.9 - 1.05 [ -- ] (550/500/588MHz)
0.90 - 1.0 - 1.05 [0.93] (660/600/800MHz)
Idle power consumption doesn't appear to be influenced much,
but a simple load test (`cat /dev/urandom | pigz - > /dev/null`
combined with running Animatch) seems to show about 0.3W of
difference.
Care is advised, as there may be differences between each
units in how low can they be undervolted - in my experience,
reaching that point usually makes the phone fail to boot.
In my case, it appears that my Birch phone can go down the most.
This is a somewhat conservative set of values that I've seen
working well on all my devices; I haven't tried very hard to
optimize it, so more experiments are welcome.

Calling '__v9fs_get_acl' method in 'v9fs_get_acl' creates the
following chain of function calls:
__v9fs_get_acl
v9fs_fid_get_acl
v9fs_fid_xattr_get
p9_client_xattrwalk
Function p9_client_xattrwalk accepts a pointer to u64-typed
variable attr_size and puts some u64 value into it. However,
after the executing the p9_client_xattrwalk, in some circumstances
we assign the value of u64-typed variable 'attr_size' to the
variable 'retval', which we will return. However, the type of
'retval' is ssize_t, and if the value of attr_size is larger
than SSIZE_MAX, we will face the signed type overflow. If the
overflow occurs, the result of v9fs_fid_xattr_get may be
negative, but not classified as an error. When we try to allocate
an acl with 'broken' size we receive an error, but don't process
it. When we try to free this acl, we face the 'wild-memory-access'
error (because it wasn't allocated).
This patch will add new condition to the 'v9fs_fid_xattr_get'
function, so it will return an EOVERFLOW error if the 'attr_size'
is larger than SSIZE_MAX.
In this version of the patch I simplified the condition.
In previous (v2) version of the patch I removed explicit type conversion
and added separate condition to check the possible overflow and return
an error (in v1 version I've just modified the existing condition).
Tested via syzkaller.

Current code always maps MMIO devices as shared (decrypted) in a
confidential computing VM. But Hyper-V guest VMs on AMD SEV-SNP with vTOM
use a paravisor running in VMPL0 to emulate some devices, such as the
IO-APIC and TPM. In such a case, the device must be accessed as private
(encrypted) because the paravisor emulates the device at an address below
vTOM, where all accesses are encrypted.
Add a new hypervisor callback to determine if an MMIO address should
be mapped private. The callback allows hypervisor-specific code to handle
any quirks, the use of a paravisor, etc. in determining whether a mapping
must be private. If the callback is not used by a hypervisor, default
to returning "false", which is consistent with normal coco VM behavior.
Use this callback as another special case to check for when doing
ioremap(). Just checking the starting address is sufficient as an
ioremap range must be all private or all shared.
Also make the callback in early boot IO-APIC mapping code that uses the
fixmap.

- Add a AMX ptrace self test
- Prevent a false-positive warning when retrieving the (invalid)
address of dynamic FPU features in their init state which are not
saved in init_fpstate at all
- Randomize per-CPU entry areas only when KASLR is enabled

Convert 'pwm_chip_to_gb_pwm_chip' from a macro to a static
inline function, to make the relevant types apparent in the
definition and to benefit from the type checking performed by
the compiler at call sites.

The remap of fill and completion rings was frowned upon as they
control the usage of UMEM which does not support concurrent use.
At the same time this would disallow the remap of these rings
into another process.
A possible use case is that the user wants to transfer the socket/
UMEM ownership to another process (via SYS_pidfd_getfd) and so
would need to also remap these rings.
This will have no impact on current usages and just relaxes the
remap limitation.

Add extended call instructions. Uses the term "program-local" for
call by offset. And there are instructions for calling helper functions
by "address" (the old way of using integer values), and for calling
helper functions by BTF ID (for kfuncs).
