Christophe Leroy 385e89d5b2 powerpc/mm: add exec protection on powerpc 603 ... The 603 doesn't have a HASH table, TLB misses are handled by software. It is then possible to generate page fault when _PAGE_EXEC is not set like in nohash/32. There is one "reserved" PTE bit available, this patch uses it for _PAGE_EXEC. In order to support it, set_pte_filter() and set_access_flags_filter() are made common, and the handling is made dependent on MMU_FTR_HPTE_TABLE Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>		2018-12-19 18:56:32 +11:00
