Similar comments to 1/4.
-  Last line of first paragraph can be rephrased like " ... on kexec,
do not contain architecture specific code, but are currently limited to
powerpc."
-  This patch should be limited to moving existing functions.  
Truncate the Subject line to "Move arch independent IMA kexec functions
to ima_kexec.c."
- Don't refer to a later patch, but explain the purpose here.  For
example, "Move ... , making them accessible to other archs."
- The definition of "FDT_PROP_IMA_KEXEC_BUFFER" should be made as a
separate, prepartory patch, prior to the existing 1/4.  The resulting
code being moved in this patch (and similarly for 1/4) will be exactly
the same as the code being deleted.

thanks,

Mimi
