  MAINTAINERS: Consolidate core exec/vCPU handling section (2025-03-09 17:00:47 +0100)

----------------------------------------------------------------
Generic CPUs / accelerators patch queue

- Reduce "exec/tb-flush.h" inclusion on linux-user
- Consider alignment in bsd-user's mmap_find_vma()
- Unify MMAP common user emulation API
- Simplify cpu-target.c further
- Prefer cached CpuClass over CPU_GET_CLASS() macro
- Restrict CPU has_work() handlers to system emulation
- Consolidate core exec/vCPU section in MAINTAINERS

Following spurious checkpatch error deliberately ignored:
