  "message": "sh: Provide a sane valid_phys_addr_range() to prevent TLB reset with PMB.\n\nWith the PMB enabled, only P1SEG and up are covered by the PMB mappings,\nmeaning that situations where out-of-bounds physical addresses are read\nfrom will lead to TLB reset after the PMB miss, allowing for use cases\nlike dd if\u003d/dev/mem to reset the TLB.\n\nFix this up to make sure the reference is between __MEMORY_START (phys)\nand __pa(high_memory). This is coherent across all variants of sh/sh64\nwith and without MMU, though the PMB bug itself is only applicable to\nSH-4A parts.\n\nReported-by: Hideo Saito \u003csaito@densan.co.jp\u003e\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n",
