DMA transfers must be greater than the watermark level size. spi_imx->rx_wml and spi_imx->tx_wml contain the watermark level in 32bit words whereas struct spi_transfer contains the transfer len in bytes. Fix the check if DMA is possible for a transfer accordingly. This fixes transfers with sizes between 33 and 128 bytes for which previously was claimed that DMA is possible.

Regression fix for systemd getting confused about unknown connector state after resume. Just stop setting the state to unknown, turned out to be a silly idea anyway. What drivers imo really should do (and i915 still does that) is forcing a full reprobe on resume to make sure connector changes while suspended are caught. Most drivers seem to get this wrong. Otoh it took us years to get fixes merged where some probe races resulted in eating uevents, I guess userspace expectations for reliable hpd are just really low :( * tag 'topic/drm-fixes-2015-07-23' of git://anongit.freedesktop.org/drm-intel: drm: Stop resetting connector state to unknown

The handling of in detach_mounts of unmounted but connected mounts is buggy and can lead to an infinite loop. Correct the handling of unmounted mounts in detach_mount. When the mountpoint of an unmounted but connected mount is connected to a dentry, and that dentry is deleted we need to disconnect that mount from the parent mount and the deleted dentry. Nothing changes for the unmounted and connected children. They can be safely ignored. Cc: stable@vger.kernel.org Fixes: ce07d891 mnt: Honor MNT_LOCKED when detaching mounts Signed-off-by:

This continues the attempt to fix commit fb170fb4 ("iommu/vt-d: Introduce helper functions to make code symmetric for readability"). The previous attempt in commit 71684406 ("iommu/vt-d: Detach domain *only* from attached iommus") overlooked the fact that dmar_domain.iommu_bmp gets cleared for VM domains when devices are detached: intel_iommu_detach_device domain_remove_one_dev_info domain_detach_iommu The domain is detached from the iommu, but the iommu is still attached to the domain, for whatever reason. Thus when we get to domain_exit(), we can't rely on iommu_bmp for VM domains to find the active iommus, we must check them all. Without that, the corresponding bit in intel_iommu.domain_ids doesn't get cleared and repeated VM domain creation and destruction will run out of domain IDs. Meanwhile we still can't call iommu_detach_domain() on arbitrary non-VM domains or we risk clearing in-use domain IDs, as 71684406 attempted to address. It's tempting to modify iommu_detach_domain() to test the domain iommu_bmp, but the call ordering from domain_remove_one_dev_info() prevents it being able to work as fb170fb4 seems to have intended. Caching of unused VM domains on the iommu object seems to be the root of the problem, but this code is far too fragile for that kind of rework to be proposed for stable, so we simply revert this chunk to its state prior to fb170fb4.

rmdir mntpoint will result in an infinite loop when there is a mount locked on the mountpoint in another mount namespace. This is because the logic to test to see if a mount should be disconnected in umount_tree is buggy. Move the logic to decide if a mount should remain connected to it's mountpoint into it's own function disconnect_mount so that clarity of expression instead of terseness of expression becomes a virtue. When the conditions where it is invalid to leave a mount connected are first ruled out, the logic for deciding if a mount should be disconnected becomes much clearer and simpler.

It's causing piles of issues since we've stopped forcing full detect cycles in the sysfs interfaces with commit c484f02d Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Mar 6 12:36:42 2015 +0000 drm: Lighten sysfs connector 'status' The original justification for this was that the hpd handlers could use the unknown state as a hint to force a full detection. But current i915 code isn't doing that any more, and no one else really uses reset on resume. So instead just keep the old state around.
