The kernel page table splitting code will split page tables even for features the CPU does not support. E.g. a CPU may not support the NX feature. In order to avoid this, remove those bits from the flags parameter that correlate with unsupported CPU features within __set_memory(). In addition add an early exit if the flags parameter does not have any bits set afterwards. Signed-off-by:Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by:
