This series continues the work of reducing fs/ext4l/ext4_uboot.h by
moving definitions to their proper locations in include/linux/ headers.

The ext4_uboot.h file provides Linux kernel compatibility for the ext4l
filesystem driver. Many definitions were placed there temporarily during
initial development. This series moves them to standard header locations
matching the Linux kernel organisation:

- Inode locking stubs and helpers to linux/fs.h
- Compiler helpers (data_race, might_sleep) to linux/compiler.h and
  linux/kernel.h
- Instruction pointer macros to linux/kernel.h
- Credential types (user_namespace) to linux/cred.h
- Filesystem types (fstrim_range) to linux/fs.h
- Quota types (qsize_t) to linux/quotaops.h
- String helpers (memweight) to linux/string.h
- UID/GID helpers to new linux/highuid.h
- Overflow helpers (struct_size) to new linux/overflow.h
- Min/max helpers (umin) to linux/minmax.h
- Slab helpers (KMEM_CACHE) to linux/slab.h
- Rate limit helpers (WARN_RATELIMIT) to linux/ratelimit.h
- Cycle counter (get_cycles) to new asm-generic/timex.h
- Superblock definition (struct super_block) to new linux/fs/super_types.h

This reduces ext4_uboot.h from 1666 to 1620 lines.
