Subject: [PATCH] PA-RISC: Fix bogus warnings from modpost


parisc and parisc64 seem to name sections a little differently from other
targets.  parisc64 gives spurious warnings like:

WARNING: drivers/net/dummy.o - Section mismatch: reference to .init.text:dummy_setup from .data.rel.ro between '.LC1' (at offset 0x0) and '.LC6'

and parisc gives spurious warnings like:

WARNING: drivers/net/dummy.o - Section mismatch: reference to .init.text:dummy_setup from .rodata.cst4 between '.LC1' (at offset 0x0) and '.LC6'

Given the other comments in modpost.c, it seems that the best solution
is to move rodata down to the 'match at start of name' section and add
.data.rel.ro to the 'match entire name' section.
