Thus spake Benjamin Herrenschmidt (benh@kernel.crashing.org):

> Hrm. This is really strange...

Is this a problem? in pte-8xx.h you added:

+#define _PAGE_SPECIAL  0x0008  /* SW entry, forced to 0 by the TLB miss */

but there is already this:

#define _PAGE_EXEC      0x0008  /* software: i-cache coherency required */

take care!
