>From the last discussion [1], some more platforms (s390, mips, csky, nios2, openrisc) were willing to enable ARCH_HAS_VM_GET_PAGE_PROT and also provide custom vm_get_page_prot() via switch case statement implementation without any objection. All those platform specific patches have already been acked. This series makes protection_map[] array private on platforms which define their own vm_get_page_prot() via ARCH_HAS_VM_GET_PAGE_PROT, and also drops off their __PXXX/__SXXX macros. This also enables new platforms as in this series, to drop off their __PXXX/__SXXX macros as generic protection_map[] is no longer visible to them.
