Roland Dreier reported in http://lkml.org/lkml/2008/2/27/194 [ 8425.915139] BUG: unable to handle kernel paging request at ffffc20001a0a000 [ 8425.919087] IP: [<ffffffff8021dacc>] clflush_cache_range+0xc/0x25 [ 8425.919087] PGD 1bf80e067 PUD 1bf80f067 PMD 1bb497067 PTE 80000047000ee17b This is on a Intel machine with 36bit physical address space. The PTE entry references 47000ee000, which is outside of it. Add a check for the physical address space and warn/printk about the stupid caller.
