Analyze and fix the following issue in the Linux kernel code: powerpc: Further compile fixup for STRICT_MM_TYPECHECKS
Problem Details: A patch of mine was recently committed to fix up STRICT_MM_TYPECHECKS behaviour on powerpc (f5ea64dcbad89875d130596df14c9b25d994a737). However, something which breaks it again seems to have slipped in afterwards. So, here's another small fix. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> ...
