Miller" To: torvalds@osdl.org Cc: akpm@osdl.org, linux-arch -at- vger Subject: [BK] flush_cache_page() pfn arg addition Linus, please pull from: bk://kernel.bkbits.net/davem/flush_cache_page-2.6 to get these changesets. Like the set_pte() changes I just sent off, this stuff simplifies ARM, SH, and SH64 ports significantly. These three chips can have cache variants which require a physical page frame number in order to flush the cache properly. And like the set_pte() case, this new argument is available in all the call sites already. What these people do right now is walk the page tables for the given vma->vm_mm+addr combination and read out the pte, and that's kind of silly and expensive. Most platforms simply nop out the new arg or ignore it as is usual practice with such interface changes. This also has the necessary documentation updates as well. It has been build and run tested on several platforms. Thanks. ChangeSet@1.2049.4.1, 2005-02-25 16:36:06-08:00, davem@nuts.davemloft.net [MM]: Add 'pfn' arg to flush_cache_page().
