git://git.kernel.org/pub/scm/linux/kernel/git/konrad/mm Pull frontswap feature from Konrad Rzeszutek Wilk: "Frontswap provides a "transcendent memory" interface for swap pages. In some environments, dramatic performance savings may be obtained because swapped pages are saved in RAM (or a RAM-like device) instead of a swap disk. This tag provides the basic infrastructure along with some changes to the existing backends." Fix up trivial conflict in mm/Makefile due to removal of swap token code changing a line next to the new frontswap entry. This pull request came in before the merge window even opened, it got delayed to after the merge window by me just wanting to make sure it had actual users. Apparently IBM is using this on their embedded side, and Jan Beulich says that it's already made available for SLES and OpenSUSE users. Also acked by Rik van Riel, and Konrad points to other people liking it too. So in it goes.

2012-06-04drm/i915: hold forcewake around ring hw initDaniel Vetter
Empirical evidence suggests that we need to: On at least one ivb machine when running the hangman i-g-t test, the rings don't properly initialize properly - the RING_START registers seems to be stuck at all zeros. Holding forcewake around this register init sequences makes chip reset reliable again. Note that this is not the first such issue: commit f01db988ef6f6c70a6cc36ee71e4a98a68901229 Author: Sean Paul <seanpaul@chromium.org> Date: Fri Mar 16 12:43:22 2012 -0400 drm/i915: Add wait_for in init_ring_common added delay loops to make RING_START and RING_CTL initialization reliable on the blt ring at boot-up. So I guess it won't hurt if we do this unconditionally for all force_wake needing gpus. To avoid copy&pasting of the HAS_FORCE_WAKE check I've added a new intel_info bit for that. v2: Fixup missing commas in static struct and properly handling the error case in init_ring_common, both noticed by Jani Nikula.

2012-06-04drm/i915: Mark the ringbuffers as being in the GTT domainChris Wilson
By correctly describing the rinbuffers as being in the GTT domain, it appears that we are more careful with the management of the CPU cache upon resume and so prevent some coherency issue when submitting commands to the GPU later. A secondary effect is that the debug logs are then consistent with the actual usage (i.e. they no longer describe the ringbuffers as being in the CPU write domain when we are accessing them through an wc iomapping.)

2012-06-04iommu/amd: Fix deadlock in ppr-handling error pathJoerg Roedel
In the error path of the ppr_notifer it can happen that the iommu->lock is taken recursivly. This patch fixes the problem by releasing the iommu->lock before any notifier is invoked. This also requires to move the erratum workaround for the ppr-log (interrupt may be faster than data in the log) one function up.

2012-06-04IB/mlx4: Fix EQ deallocation in legacy modeShlomo Pongratz
Commit e605b743f33d ("IB/mlx4: Increase the number of vectors (EQs) available for ULPs") didn't handle correctly the case where there aren't enough MSI-X vectors to increase the number of EQs, so only the legacy EQs are allocated. This results in an attempt to memset() to zero the EQ table which was never allocated and a kernel crash. Fix this by checking in the teardown flow if the table of EQs was ever allocated. Also remove some unneeded setting to zero of the EQ related fields in struct mlx4_ib_dev.

2012-06-03target/file: Use O_DSYNC by default for FILEIO backendsNicholas Bellinger
Convert to use O_DSYNC for all cases at FILEIO backend creation time to avoid the extra syncing of pure timestamp updates with legacy O_SYNC during default operation as recommended by hch. Continue to do this independently of Write Cache Enable (WCE) bit, as WCE=0 is currently the default for all backend devices and enabled by user on per device basis via attrib/emulate_write_cache. This patch drops the now unnecessary fd_buffered_io= token usage that was originally signalling when to explictly disable O_SYNC at backend creation time for buffered I/O operation. This can end up being dangerous for a number of reasons during physical node failure, so go ahead and drop this option for now when O_DSYNC is used as the default. Also allow explict FUA WRITEs -> vfs_fsync_range() call to function in fd_execute_cmd() independently of WCE bit setting.

2012-06-02dm thin: provide userspace access to pool metadataJoe Thornber
This patch implements two new messages that can be sent to the thin pool target allowing it to take a snapshot of the _metadata_. This, read-only snapshot can be accessed by userland, concurrently with the live target. Only one metadata snapshot can be held at a time. The pool's status line will give the block location for the current msnap. Since version 0.1.5 of the userland thin provisioning tools, the thin_dump program displays the msnap as follows: thin_dump -m <msnap root> <metadata dev> Available here: https://github.com/jthornber/thin-provisioning-tools Now that userland can access the metadata we can do various things that have traditionally been kernel side tasks: i) Incremental backups. By using metadata snapshots we can work out what blocks have changed over time. Combined with data snapshots we can ensure the data doesn't change while we back it up. A short proof of concept script can be found here: https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb ii) Migration of thin devices from one pool to another. iii) Merging snapshots back into an external origin. iv) Asyncronous replication.

2012-06-02dm mpath: allow ioctls to trigger pg initMikulas Patocka
After the failure of a group of paths, any alternative paths that need initialising do not become available until further I/O is sent to the device. Until this has happened, ioctls return -EAGAIN. With this patch, new paths are made available in response to an ioctl too. The processing of the ioctl gets delayed until this has happened. Instead of returning an error, we submit a work item to kmultipathd (that will potentially activate the new path) and retry in ten milliseconds. Note that the patch doesn't retry an ioctl if the ioctl itself fails due to a path failure. Such retries should be handled intelligently by the code that generated the ioctl in the first place, noting that some SCSI commands should not be retried because they are not idempotent (XOR write commands). For commands that could be retried, there is a danger that if the device rejected the SCSI command, the path could be errorneously marked as failed, and the request would be retried on another path which might fail too. It can be determined if the failure happens on the device or on the SCSI controller, but there is no guarantee that all SCSI drivers set these flags correctly.

2012-06-02dm mpath: delay retry of bypassed pgMike Christie
If I/O needs retrying and only bypassed priority groups are available, set the pg_init_delay_retry flag to wait before retrying. If, for example, the reason for the bypass is that the controller is getting reset or there is a firmware upgrade happening, retrying right away would cause a flood of log messages and retries for what could be a few seconds or even several minutes.

Since commit 6a918bade9dab40aaef80559bd1169c69e8d69cb, the mxc_nand driver fails with: Driver must set ecc.strength when using hardware ECC This is because nand_scan_tail checks for correct ecc strength settings, so we must set them up before nand_scan_tail.

2012-06-01mtd: block2mtd: fix recursive call of mtd_writevGabor Juhos
The 'mtd_writev' interface calls the function assigned to the '_write' field of a given mtd device if that is not NULL. The block2mtd driver sets the '_writev' field to the 'mtd_writev' function itself and thus causes a endless loop. This is caused by 1dbebd32562b3c2caeca35960e5cb00bfcc12900 (mtd: harmonize mtd_writev usage). Remove the assignment from the block2mtd driver to fix the issue.

2012-06-018139cp/8139too: terminate the eeprom access with the right opmodeJason Wang
Currently, we terminate the eeprom access through clearing the CS by: RTL_W8 (Cfg9346, ~EE_CS); or writeb (~EE_CS, ee_addr); This would left the eeprom into "Config. Register Write Enable:" state which is not expcted as the highest two bits were set to 0x11 ( expected is the "Normal" mode (0x00)).
