2018-04-10platform/chrome: mfd/cros_ec_dev: Add sysfs entry to set keyboard wake lid angleGwendal Grignou
This adds a sysfs attribute (/sys/class/chromeos/cros_ec/kb_wake_angle) used to set and get the keyboard wake lid angle. This attribute is present only if 2 accelerometers are controlled by the EC. This patch also moves the cros_ec features check before the device is added so the features map obtained from the EC is ready on time.

The code refactoring by commit 0176adb00406 ("swiotlb: refactor coherent buffer allocation") made swiotlb_alloc_buffer almost always failing due to a thinko: namely, the function evaluates the dma_coherent_ok call incorrectly and dealing as if it's invalid.

2018-04-10NFS: advance nfs_entry cookie only after decoding completes successfullyFrank Sorenson
In nfs[34]_decode_dirent, the cookie is advanced as soon as it is read, but decoding may still fail later in the function, returning an error. Because the cookie has been advanced, the failing entry is not re-requested from the server, resulting in a missing directory entry. In addition, nfs v3 and v4 read the cookie at different locations in the xdr_stream, so the behavior of the two can be inconsistent. Fix these by reading the cookie into a temporary variable, and only advancing the cookie once the entire entry has been decoded from the xdr_stream successfully.

2018-04-10NFS: More fine grained attribute trackingTrond Myklebust
Currently, if the NFS_INO_INVALID_ATTR flag is set, for instance by a call to nfs_post_op_update_inode_locked(), then it will not be cleared until all the attributes have been revalidated. This means, for instance, that NFSv4 writes will always force a full attribute revalidation. Track the ctime, mtime, size and change attribute separately from the other attributes so that we can have nfs_post_op_update_inode_locked() set them correctly, and later have the cache consistency bitmask be able to clear them.

2018-04-10NFSv4: Don't return the delegation when not needed by NFSv4.x (x>0)Trond Myklebust
