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
