Subject: [PATCH v4 00/22] Add XIP support to ext4

... or, as it should probably be called now "Complete rewrite of everything
XIP related".  It's only compile-tested; before I get too much further down
this path, I wanted to get some opinions on the approach.

Matthew Wilcox (21):
  Fix XIP fault vs truncate race
  Simplify COW of XIP mappings
  axonram: Fix bug in direct_access
  Change direct_access calling convention
  Introduce IS_XIP(inode)
  Treat XIP like O_DIRECT
  Rewrite XIP page fault handling
  Change xip_truncate_page to take a get_block parameter
  Remove mm/filemap_xip.c
  Remove get_xip_mem
  Replace ext2_clear_xip_target with xip_clear_blocks
  ext2: Remove ext2_xip_verify_sb()
  ext2: Remove ext2_use_xip
  ext2: Remove xip.c and xip.h
  Remove CONFIG_EXT2_FS_XIP
  ext2: Remove ext2_aops_xip
  xip: Add xip_zero_page_range
  ext4: Make ext4_block_zero_page_range static
  ext4: Fix typos
  Add support for pmd_faults
  xip: Add reporting of major faults

Ross Zwisler (1):
  ext4: Add XIP functionality
