The ext4l filesystem uses a large compatibility header (ext4_uboot.h)
containing stubs for Linux kernel interfaces. This series moves these
stubs to their proper locations in include/linux/, making them available
to other subsystems and improving code organisation.

The series:
- Fixes list_sort() callback signature to match Linux kernel
- Moves struct definitions and stubs to appropriate linux/ headers
- Adds missing stubs to existing headers (fs.h, blkdev.h, slab.h, etc.)
- Creates new stub headers where needed (iomap.h, super_types.h)
- Consolidates and sorts the remaining includes

This reduces ext4_uboot.h from over 550 lines to around 270 lines. At
this point, the work can be considered complete.

  linux/sort.h: Fix qsort implicit declaration warning
  list: Add const qualifiers to list_sort callback signature
  ext4l: Remove redundant header-location comments from ext4_uboot.h
  ext4l: Move file_operations and inode_operations to linux/fs.h
  ext4l: Move struct inode and time accessors to linux/fs.h
  ext4l: Move sb_ functions and SB_ macros to super_types.h
  ext4l: Move seq_ functions to linux/seq_file.h
  ext4l: Move inode state accessors to linux/fs.h

  ext4l: Move O_SYNC, S_NOQUOTA and kfree_link to headers
  linux: Add PAGE_SHIFT and PAGE_MASK to linux/compat.h
  linux: Add DEFINE_RAW_FLEX to linux/overflow.h
  ext4l: Consolidate and sort includes in ext4_uboot.h
