Currently gup_longterm assumes that filesystems support fallocate() and uses
that to allocate space in files, however this is an optional feature and is
in particular not implemented by NFSv3 which is commonly used in CI systems
leading to spurious failures. Check for lack of support and report a s

Hello,
this series follows some discussions started in [1] around bpf
trampolines limitations on specific cases. When a trampoline is
generated for a target function involving many arguments, it has to
properly find and save the arguments that has been passed through stack.
While this is doable wit
powerpc allows using up to 8 registers to pass arguments between function
calls. This value is hardcoded in multiple places, use a define for this
value.

When attaching ebpf programs to functions through fentry/fexit, the
generated trampolines can not really make sure about the arguments exact
location on the stack if those are structures: those structures can be
altered with attributes such as packed or aligned(x), but this
information is not encod

The new TEE remoteproc driver is used to manage remote firmware in a
secure, trusted context. The 'st,stm32mp1-m4-tee' compatibility is
introduced to delegate the loading of the firmware to the trusted
execution context. In such cases, the firmware should be signed and

The "st,stm32mp1-m4-tee" compatible is utilized in a system configuration
where the Cortex-M4 firmware is loaded by the Trusted Execution Environment
