LoongArch: Wire up memfd_secret system call
...
LoongArch supports ARCH_HAS_SET_DIRECT_MAP, therefore wire up the
memfd_secret system call, which just depends on it.

selftests/bpf: Use asm constraint "m" for LoongArch
...
Currently, LoongArch LLVM does not support the constraint "o" and no plan
to support it, it only supports the similar constraint "m", so change the
constraints from "nor" in the "else" case to arch-specific "nmr" to avoid
the build error such as "unexpected asm memory constraint" for LoongArch.
Fixes: 630301b0d59d ("selftests/bpf: Add basic USDT selftests")

kunit: qemu_configs: loongarch: Enable shutdown
...
QEMU for LoongArch does not yet support shutdown/restart through ACPI.
Use the pvpanic driver to enable shutdowns.
This requires 9.1.0 for shutdown support in pvpanic, but that is the
requirement of kunit on LoongArch anyways.

kunit: qemu_configs: Add LoongArch config
...
Add a basic config to run kunit tests on LoongArch.
This requires QEMU 9.1.0 or later for the necessary direct kernel boot
support.
