linuxkpi: Define `ULL()`
It simply appends "ULL" to its argument.
The amdgpu DRM driver used it at some point in the development cycle of
Linux 6.14 but the use case was dropped later. Let's still add it to
linuxkpi because it will help if we need to do a git bisect in drm-kmod.

linuxkpi: Define `struct vfsmount` in <linux/mount.h>
In the context of the DRM drivers, this is used to show GEM objects in a
shmfs virtual filesystem. The new `shmem_file_setup_with_mnt()` - also
introduced in this commit as an alias to `shmem_file_setup()` - takes a
`struct vfsmount` as its first argument to indicate which shmfs mount
should be used.
For now, the structure is empty. As we don't present GEM objects in a
virtual filesystem right now, we can defer the actual implementation of
this structure once we have an actual use for it.
The DRM generic code started to use it in Linux 6.13.

Add Netlink payload decoding support for sendto(), recvfrom(), and

libnetbsd: Avoid bringing in all of sys/param.h in sys/types.h
It's okay to hard-code NBBY, as the value is somewhat unlikely to

The pollution from sys/param.h makes it harder to import test code from
NetBSD since it can introduce conflicting definitions, e.g.,
MIN()/MAX().

sound: Retire unused SD_F_EQ_PC
This flag is neither set anywhere, nor is there a way to set it from
userland, so it is effectively useless, and currently the effect is that
EQ can only be enabled for primary playback channels.
Retire the flag and keep this behavior, and think later whether we want
to allow virtual channels to get their own EQ feeder as well.

riscv: Vector Extension (RVV) support.
RVV is a scalable SIMD (Single Instruction, Multiple Data) extension
designed to accelerate data-intensive workload such as AI, machine-learning
and DSP.
RVV exposes vector-length agnostic (VLA) execution and programming model,
with implementation defined vector register file size, dynamic vector
length selection, flexible register grouping, and rich instruction
semantics, serving as the foundation for portable, high-throughput
data-parallel acceleration.
Spec: https://github.com/riscvarchive/riscv-v-spec
RVV extends a base scalar RISC-V ISA with 32 vector registers and seven
unprivileged control-status registers (CSRs) to control the engine. Each
vector register could be up to 2^16 bits in length, depending on
implementation.

* In MockFS::write_response, write(2) may fail if m_fuse_fd has already
