Xavier Roumegue authored
Add a V4L2 mem-to-mem driver for the Vivante DW100 Dewarp Processor IP core found on i.MX8MP SoC. The processor core applies a programmable geometrical transformation on input images to correct distorsion introduced by lenses. The transformation function is exposed as a grid map with 16x16 pixel macroblocks indexed using X, Y vertex coordinates. The dewarping map can be set from application through a dedicated v4l2 control. If not set or invalid, the driver computes an identity map prior to starting the processing engine. The driver supports scaling, cropping and pixel format conversion.

Enable multipage folio support for the afs filesystem. Support has already been implemented in netfslib, fscache and cachefiles and in most of afs, but I've waited for Matthew Wilcox's latest folio changes. Note that it does require a change to afs_write_begin() to return the correct subpage. This is a "temporary" change as we're working on getting rid of the need for ->write_begin() and ->write_end() completely, at least as far as network filesystems are concerned - but it doesn't prevent afs from making use of the capability.
