Still getting the 'WARNING: at arch/x86/mm/ioremap.c:137
__ioremap+0xb1/0x165()' error in -rc5. Seen a few threads on this
error, but apparently still not resolved. Anyone need more info?

the warning is harmless and will be removed in the next x86 update.
(patch is queued up in x86.git already, see below.)
