2012-06-22SCSI & usb-storage: add try_rc_10_first flagAlan Stern
Several bug reports have been received recently for USB mass-storage devices that don't handle READ CAPACITY(16) commands properly. They report bogus sizes, in some cases becoming unusable as a result. The bugs were triggered by commit 09b6b51b0b6c1b9bb61815baf205e4d74c89ff04 (SCSI & usb-storage: add flags for VPD pages and REPORT LUNS), which caused usb-storage to stop overriding the SCSI level reported by devices. By default, the sd driver will try READ CAPACITY(16) first for any device whose level is above SCSI_SPC_2. It seems likely that any device large enough to require the use of READ CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ CAPACITY(10) commands properly. Indeed, I don't know of any devices that don't handle READ CAPACITY(10) properly. Therefore this patch (as1559) adds a new flag telling the sd driver to try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag for every USB mass-storage device. If a device really is larger than 2 TB, sd will fall back to READ CAPACITY(16) just as it used to. This fixes Bugzilla #43391.

2012-06-22r8169: RxConfig hack for the 8168evl.françois romieu
The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards are very prone to NETDEV watchdog problems without this change. See https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance. I don't know why it *works*. It's depressingly effective though. For the record: - the problem may go along IOMMU (AMD-Vi) errors but it really looks like a red herring. - the patch sets the RX_MULTI_EN bit. If the 8168c doc is any guide, the chipset now fetches several Rx descriptors at a time. - long ago the driver ignored the RX_MULTI_EN bit. e542a2269f232d61270ceddd42b73a4348dee2bb changed the RxConfig settings. Whatever the problem it's now labeled a regression. - Realtek's own driver can identify two different 8168evl devices (CFG_METHOD_16 and CFG_METHOD_17) where the r8169 driver only sees one. It sucks.

2012-06-23drm/i915: rip out the PM_IIR WARNDaniel Vetter
After banging my head against this for the past few months, I still don't see how this could possible race under the premise that once an irq bit is masked in PM_IMR and reset in PM_IIR it won't show up again until we unmask it in PM_IMR. Still, we have reports of this being seen in the wild. Now Bspec has this little bit of lovely language in the PMIIR register: Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR": "For each bit, the IIR can store a second pending interrupt if two or more of the same interrupt conditions occur before the first condition is cleared. Upon clearing the interrupt, the IIR bit will momentarily go low, then return high to indicate there is another interrupt pending." Now if we presume that PMIMR only prevent new interrupts from being queued, we could easily end up masking an interrupt and clearing it, but the 2nd pending interrupt setting the bit in PMIIR right away again. Which leads, the next time the irq handler runs, to hitting the WARN. Also, no bad side effects of this have ever been reported. And we've tracked down our issues with the gpu turbo getting stuck to bogus interrupt generation limits in th RPLIMIT register. So let's just rip out this WARN as bogus and call it a day. The only shallow thing here is that this 2-deep irq queue in the hw makes you wonder how racy the windows irq handler is ...

2012-06-21xfs: Fix overallocation in xfs_buf_allocate_memory()Jan Kara
Commit de1cbee which removed b_file_offset in favor of b_bn introduced a bug causing xfs_buf_allocate_memory() to overestimate the number of necessary pages. The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively every buffer is straddling a page boundary which causes xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access which is unnecessary. Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the buffer is inserted into the cache only after being fully initialized now. So just make xfs_buf_alloc() fill in proper block number from the beginning.

An inode in the AIL can be flush locked and marked stale if a cluster free transaction occurs at the right time. The inode item is then marked as flushing, which causes xfsaild to spin and leaves the filesystem stalled. This is reproduced by running xfstests 273 in a loop for an extended period of time. Check for stale inodes before the flush lock. This marks the inode as pinned, leads to a log flush and allows the filesystem to proceed.

We need to initialize this to false, because the is_rb callback only ever sets it to true. Noticed while reading through the code.

2012-06-20mm, mempolicy: fix mbind() to do synchronous migrationDavid Rientjes
If the range passed to mbind() is not allocated on nodes set in the nodemask, it migrates the pages to respect the constraint. The final formal of migrate_pages() is a mode of type enum migrate_mode, not a boolean. do_mbind() is currently passing "true" which is the equivalent of MIGRATE_SYNC_LIGHT. This should instead be MIGRATE_SYNC for synchronous page migration. Signed-off-by: David Rientjes <rientjes@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
