Merge branch 'topic/func-desc-lkdtm' into next
Merge a topic branch we are maintaining with some cross-architecture
changes to function descriptor handling and their use in LKDTM.
From Christophe's cover letter:
Fix LKDTM for PPC64/IA64/PARISC
PPC64/IA64/PARISC have function descriptors. LKDTM doesn't work on those
three architectures because LKDTM messes up function descriptors with
functions.
This series does some cleanup in the three architectures and refactors
function descriptors so that it can then easily use it in a generic way
in LKDTM.
