Stupid me, hex formatting would have been easier to read :)
Lookup failed for 0xFFFF 8100 8C08 0000
ioremap: 0x0000 0000 8C08 0000 length 16384
It seems, that this patch only reveals some other wreckage. The code is
called as part of ioremap, where it adjusts the caching attributes of
the mapping, which was setup right before change_page_attr_address() is
called.
