Aside from the bug Jan pointed out with the patch, we're also using
cflflush in other places (arch/i386/kernel/alternative.c and
arch/x86_64/kernel/tce.c). Is the issue with clflush support specific
to pageattr.c or should it be disabled every else too? what
specifically is the issue?

Cheers,
Muli
