Subject: [PATCH] - 2.6 fixes:   - mds_lock_new_child() uses specific namespace
 to avoid deadlock     if i_generations == 0   - portals_debug_copy_to_user()
 uses kmap_atomic() instead of     kmap() because it's called beinged locked
 with disabled interrupts   - ugly hacks which prevent userspace tools to try
 to load modules   - corrections in Makefiles   - minor compatibility defines
 and tweaks   - inode->c_index is used as orphans counter   -
 ll_lookup_finish_locks() doesn't release intent     because on 2.6 it may be
 needed several times   - check that nd isn't NULL before using   -
 ll_update_inode() decoded dev number wrong way   - PDE define is used to
 retrieve procfs-related data   - rw26.c is almost copy of rw24.c   -
 super25.c registers lustre and lustre_lite

- 2.6 kernel patches:
  - 2.6.0-mm2
  - dev_read_only_2.6.0.patch stores dev number, not struct block_device *
  - ext3-init-generation-2.6.0.patch - lustre dislikes when ext3 resets
    s_next_generation to 0 upon mount
  - ext3-map_inode_page-2.6.0.patch - added fix to unmap underlaying metadata
  - ext3-start_this_handle-must-return-error.patch - jbd returned 0 always:
    posssible oops
  - vfs_nointent_2.6.0-test6.patch - small contexts changes
  - invalidate_show-2.6.0.patch - port onto 2.6
  - iopen-2.6.0-test6.patch - several fixes
  - vfs_intent_2.6.0.patch - port onto 2.5.0
  - kernel_text_address-2.6.0.patch
  - export_symbols-2.6.0.patch

- kgdb_2.6.0 series
