Commit 3a533374 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'for-linus' of git://www.jni.nu/cris

* 'for-linus' of git://www.jni.nu/cris:
  [CRISv10] Clean up compressed/misc.c
  [CRISv10] Correct whitespace damage.
  [CRIS] Correct definition of subdirs for install_headers.
  [CRIS] Correct image makefiles to allow using a separate OBJ-directory.
  [CRIS] Build fixes for compressed and rescue images for v10 and v32:
  It looks at least odd to apply spin_unlock to a mutex.
  cris: compile fixes for 2.6.26-rc5
