  In an attempt to simplify some includes in <include/dcache.h>, it
appeared, when compiling fs/ecryptfs/dentry.c, that <linux/bit_spinlock.h>
was relying on other includes to get the definition of cpu_relax().
(see [1])

It broke on ARC.

Include <linux/processor.h> in <linux/bit_spinlock.h> to fix the issue.
This will help to remove some un-needed includes from <include/dcache.h>.
