2008-04-28[MIPS] Reimplement clear_page/copy_pageThiemo Seufer
Fold the SB-1 specific implementation of clear_page/copy_page in the generic version, and rewrite that one in tlbex style. The immediate benefits: - It converts the compile-time workaround for SB-1 pass 1 prefetches to a more efficient run-time check. - It allows adjustment of loop unfolling, which helps to reduce the number of redundant cdex cache ops. - It fixes some esoteric cornercases (the cache line length calculations can go wrong, and support for 64k pages without prefetch instructions will overflow the addiu immediate). - Somewhat better guesses of "good" prefetch values.

2008-04-28kernel-doc: detect/prevent duplicate doc section namesRandy Dunlap
I saw this problem recently. With this kernel-doc: * Note: some important info * * Note: other important info kernel-doc uses the "section name" (preceding the ':', like "Note") as a hash key for storing the descriptive text ("blah important info"). It is (was) possible to have duplicate (colliding) section names, without any kind of warning or error. kernel-doc happily used the latter descriptive text for all instances of printing the <section-name> descriptive text and the former important info was lost. One way to "fix" this is to modify the kernel-doc comments, e.g.: * Note1: foo bar * * Note.2: blah zay For now, kernel-doc will signal an error when it sees colliding section names like this.

2008-04-28fat: detect media without partition table correctlyFrank Seidel
I received a complaint that some FAT formated medias (e.g. sd memory cards) trigger a "unknown partition table" message even though there is no partition table and they work correctly, while in general (when e.g. formated with mkdosfs or even Windows Vista) this message is not shown. Currently this seems only to happen when the medias get formatted with Windows XP (and possibly Win 2000). Then the boot indicator byte contains garbage (part of text message) and so do the other parts checked by msdos_paritition which then later triggers this message. References: novell bug #364365 Most fat formatted media without partition table contains zeros in the boot indication and the other tested bytes and so falls through the checks in msdos_partition, leading it to return with 1 (all is fine). But some (e.g. WinXP formatted) fat fomated medias don't use boot_ind and so the check fails and causes a "unkown partition table" warning eventhough there is none and everything would be fine. This additional check directly verifies if there is a fat formatted medium without a partition table.

2008-04-28FAT_VALID_MEDIA(): remove pointless testAndrew Morton
The on-disk media specification field in FAT is only 8-bits, so testing for <=0xff is pointless, and can generate a "comparison is always true due to limited range of data type" warning. While we're there, convert FAT_VALID_MEDIA() into a C function - the present implementation is buggy: it generates either one or two references to its argument.
