| 2008-12-22 | sh: Move arch_get_unmapped_area() in to arch/sh/mm/mmap.c. | Paul Mundt | |
| Now that arch/sh/mm/mmap.c exists, move arch_get_unmapped_area() there. Follows the ARM change. Signed-off-by: Paul Mundt <lethal@linux-sh.org> | |||

| 2008-11-12 | sh: Provide a sane valid_phys_addr_range() to prevent TLB reset with PMB. | Paul Mundt | |
| With the PMB enabled, only P1SEG and up are covered by the PMB mappings, meaning that situations where out-of-bounds physical addresses are read from will lead to TLB reset after the PMB miss, allowing for use cases like dd if=/dev/mem to reset the TLB. Fix this up to make sure the reference is between __MEMORY_START (phys) and __pa(high_memory). This is coherent across all variants of sh/sh64 with and without MMU, though the PMB bug itself is only applicable to SH-4A parts.
