Paul Mundt 55661fc1f1 sh: Assume new page cache pages have dirty dcache lines. This follows the ARM change `c01778001a` ("ARM: 6379/1: Assume new page cache pages have dirty D-cache") for the same rationale: There are places in Linux where writes to newly allocated page cache pages happen without a subsequent call to flush_dcache_page() (several PIO drivers including USB HCD). This patch changes the meaning of PG_arch_1 to be PG_dcache_clean and always flush the D-cache for a newly mapped page in update_mmu_cache(). This addresses issues seen with executing binaries from MMC, in addition to some of the other HCDs that don't explicitly do cache management for their pipe-in buffers.
