devm_kasprintf() returns a pointer to dynamically allocated memory.
Pointer could be NULL in case allocation fails. Check pointer validity.

A process can spawn a PD on DSP with some attributes that can be
associated with the PD during spawn and run. The invocation
corresponding to the create request with attributes has total
4 buffers at the DSP side implementation. If this number is not
correct, the invocation is expected to fail on DSP. Added change
to use correct number of buffer count for creating fastrpc scalar.

This PFSM controls the operational modes of the PMIC:
- STANDBY and LP_STANDBY,
- ACTIVE state,
- MCU_ONLY state,
- RETENTION state, with or without DDR and/or GPIO retention.
Depending on the current operational mode, some voltage domains
remain energized while others can be off.
This PFSM is also used to trigger a firmware update, and provides
R/W access to device registers.
See Documentation/misc-devices/tps6594-pfsm.rst for more
information.

Patch series "remove the vmas parameter from GUP APIs", v6.
(pin_/get)_user_pages[_remote]() each provide an optional output parameter
for an array of VMA objects associated with each page in the input range.
These provide the means for VMAs to be returned, as long as mm->mmap_lock
is never released during the GUP operation (i.e. the internal flag
FOLL_UNLOCKABLE is not specified).
In addition, these VMAs can only be accessed with the mmap_lock held and
become invalidated the moment it is released.
The vast majority of invocations do not use this functionality and of
those that do, all but one case retrieve a single VMA to perform checks
upon.
It is not egregious in the single VMA cases to simply replace the
operation with a vma_lookup(). In these cases we duplicate the (fast)
lookup on a slow path already under the mmap_lock, abstracted to a new
get_user_page_vma_remote() inline helper function which also performs
error checking and reference count maintenance.
The special case is io_uring, where io_pin_pages() specifically needs to
assert that the VMAs underlying the range do not result in broken
long-term GUP file-backed mappings.
As GUP now internally asserts that FOLL_LONGTERM mappings are not
file-backed in a broken fashion (i.e. requiring dirty tracking) - as
implemented in "mm/gup: disallow FOLL_LONGTERM GUP-nonfast writing to
file-backed mappings" - this logic is no longer required and so we can
simply remove it altogether from io_uring.
Eliminating the vmas parameter eliminates an entire class of danging
pointer errors that might have occured should the lock have been
incorrectly released.
In addition, the API is simplified and now clearly expresses what it is
intended for - applying the specified GUP flags and (if pinning) returning
pinned pages.
This change additionally opens the door to further potential improvements
in GUP and the possible marrying of disparate code paths.
I have run this series against gup_test with no issues.
Thanks to Matthew Wilcox for suggesting this refactoring!
This patch (of 6):
No invocation of get_user_pages() use the vmas parameter, so remove it.
The GUP API is confusing and caveated. Recent changes have done much to
improve that, however there is more we can do. Exporting vmas is a prime
target as the caller has to be extremely careful to preclude their use
after the mmap_lock has expired or otherwise be left with dangling
pointers.
Removing the vmas parameter focuses the GUP functions upon their primary
purpose - pinning (and outputting) pages as well as performing the actions
implied by the input flags.
This is part of a patch series aiming to remove the vmas parameter
altogether.

For certain configs objtool will complain like:
vmlinux.o: warning: objtool: lkdtm_UNSET_SMEP+0x1c3: relocation to !ENDBR: native_write_cr4+0x41
What happens is that GCC optimizes the loop:
insn = (unsigned char *)native_write_cr4;
for (i = 0; i < MOV_CR4_DEPTH; i++)
to read something like:
for (insn = (unsigned char *)native_write_cr4;
insn < (unsigned char *)native_write_cr4 + MOV_CR4_DEPTH;
insn++)
Which then obviously generates the text reference
native_write_cr4+041. Since none of this is a fast path, simply
confuse GCC enough to inhibit this optimization.

The current code will, if we do not specify unique labels
for the SRAM subnodes, fail to register several nodes named
the same.
Example:
sram@40020000 {
(...)
sram@0 {
(...)
};
sram@1000 {
(...)
};
};
Since the child->name in both cases will be "sram" the
gen_pool_create() will fail because the name is not unique.
Use dev_name() for the device as this will have bus ID
set to the fully translated address for the node, and that
will always be unique.

Function ll_rw_block was removed in commit 79f597842069 ("fs/buffer:

read or write buffer in block layer for now. Consider similar sematics,
we can choose submit_bh() to replace ll_rw_block() as predefined crash
point. In submit_bh(), it also takes read or write flag as the first
argument and invoke submit_bio() to submit I/O request to block layer.

The inode can be different in a container, for example, a docker and host
both open the same uacce parent device, which uses the same uacce struct
but different inode, so uacce->inode is not enough.
What's worse, when docker stops, the inode will be destroyed as well,
causing use-after-free in uacce_remove.
So use q->mapping to replace uacce->inode->i_mapping.

The channel's rpmsg object allows new invocations to be made. After old
invocations are already interrupted, the driver shouldn't try to invoke
anymore. Invalidating the rpmsg at the end of the driver removal
function makes it easy to cause a race condition in userspace. Even
closing a file descriptor before the driver finishes its cleanup can
cause an invocation via fastrpc_release_current_dsp_process() and
subsequent timeout.
Invalidate the channel before the invocations are interrupted to make
sure that no invocations can be created to hang after the device closes.

The return value is initialized as -1, or -EPERM. The completion of an

"Permission denied" does not accurately describe the outcome of the

The userspace map request for remote heap allocates CMA memory.
The ownership of this memory needs to be reassigned to proper
owners to allow access from the protection domain running on
DSP. This reassigning of ownership is not correct if done for
any other supported flags.
When any other flag is requested from userspace, fastrpc is
trying to reassign the ownership of memory and this reassignment
is getting skipped for remote heap request which is incorrect.
Add proper flag check to reassign the memory only if remote heap
is requested.

If a map request is made with securemap attribute, the memory
ownership needs to be reassigned to new VMID to allow access
from protection domain. Currently only DSP VMID is passed to
the reassign call which is incorrect as only a combination of
HLOS and DSP VMID is allowed for memory ownership reassignment
and passing only DSP VMID will cause assign call failure.
Also pass proper restoring permissions to HLOS as the source
permission will now carry both HLOS and DSP VMID permission.
Change is also made to get valid physical address from
scatter/gather for this allocation request.

Since the child->name in both cases will be "sram" the
gen_pool_create() will fail because the name is not unique.
Use dev_name() for the device as this will have bus ID
set to the fully translated address for the node, and that
will always be unique.

When using nvmem layouts it is possible devm_nvmem_register returns

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening
in the driver core in the quest to be able to move "struct bus" and
"struct class" into read-only memory, a task now complete with these
changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
