Pull MIPS fixes from Ralf Baechle: "Random fixes across the MIPS tree. The two hotspots are several bugs in the module loader and the ath79 SOC support; also noteworthy is the restructuring of the code to synchronize CPU timers across CPUs on startup; the old code recently ceased to work due to unrelated changes. All except one of these patches have sat for a significant time in linux-next for testing." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: pci-ar724x: avoid data bus error due to a missing PCIe module MIPS: Malta: Delete duplicate PCI fixup.

Pull block-related fixes from Jens Axboe: - Improvements to the buffered and direct write IO plugging from Fengguang. - Abstract out the mapping of a bio in a request, and use that to provide a blk_bio_map_sg() helper. Useful for mapping just a bio instead of a full request. - Regression fix from Hugh, fixing up a patch that went into the previous release cycle (and marked stable, too) attempting to prevent a loop in __getblk_slow(). - Updates to discard requests, fixing up the sizing and how we align them. Also a change to disallow merging of discard requests, since that doesn't really work properly yet. - A few drbd fixes. - Documentation updates. * 'for-linus' of git://git.kernel.dk/linux-block: block: replace __getblk_slow misfix by grow_dev_page fix drbd: Write all pages of the bitmap after an online resize drbd: Finish requests that completed while IO was frozen drbd: fix drbd wire compatibility for empty flushes Documentation: update tunable options in block/cfq-iosched.txt Documentation: update tunable options in block/cfq-iosched.txt Documentation: update missing index files in block/00-INDEX block: move down direct IO plugging block: remove plugging at buffered write time block: disable discard request merge temporarily bio: Fix potential memory leak in bio_find_or_create_slab() block: Don't use static to define "void *p" in show_partition_start() block: Add blk_bio_map_sg() helper block: Introduce __blk_segment_map_sg() helper fs/block-dev.c:fix performance regression in O_DIRECT writes to md block devices block: split discard into aligned requests block: reorganize rounding of max_discard_sectors

Hugh Dickins authored
Commit 91f68c89 ("block: fix infinite loop in __getblk_slow") is not good: a successful call to grow_buffers() cannot guarantee that the page won't be reclaimed before the immediate next call to __find_get_block(), which is why there was always a loop there. Yesterday I got "EXT4-fs error (device loop0): __ext4_get_inode_loc:3595: inode #19278: block 664: comm cc1: unable to read itable block" on console, which pointed to this commit. I've been trying to bisect for weeks, why kbuild-on-ext4-on-loop-on-tmpfs sometimes fails from a missing header file, under memory pressure on ppc G5. I've never seen this on x86, and I've never seen it on 3.5-rc7 itself, despite that commit being in there: bisection pointed to an irrelevant pinctrl merge, but hard to tell when failure takes between 18 minutes and 38 hours (but so far it's happened quicker on 3.6-rc2). (I've since found such __ext4_get_inode_loc errors in /var/log/messages from previous weeks: why the message never appeared on console until yesterday morning is a mystery for another day.) Revert 91f68c89, restoring __getblk_slow() to how it was (plus a checkpatch nitfix). Simplify the interface between grow_buffers() and grow_dev_page(), and avoid the infinite loop beyond end of device by instead checking init_page_buffers()'s end_block there (I presume that's more efficient than a repeated call to blkdev_max_block()), returning -ENXIO to __getblk_slow() in that case. And remove akpm's ten-year-old "__getblk() cannot fail ... weird" comment, but that is worrying: are all users of __getblk() really now prepared for a NULL bh beyond end of device, or will some oops??

Andreas Herrmann authored
This issue was recently observed on an AMD C-50 CPU where a patch of maximum size was applied. Commit be62adb4 ("x86, microcode, AMD: Simplify ucode verification") added current_size in get_matching_microcode(). This is calculated as size of the ucode patch + 8 (ie. size of the header). Later this is compared against the maximum possible ucode patch size for a CPU family. And of course this fails if the patch has already maximum size.

When debugging is enabled, we use a temporary on-stack buffer for formatting the key strings like "(11368871, direntry, 0xcd0750)". The buffer size is 32 bytes and sometimes it is not enough to fit the key string - e.g., when inode numbers are high. This is not fatal, but the key strings are incomplete and UBIFS complains like this: UBIFS assert failed in dbg_snprintf_key at 137 (pid 1) This is a regression caused by "515315a1 UBIFS: fix key printing". Fix the issue by increasing the buffer to 48 bytes. Reported-by:
