Currently, the memory to the composition frame is being allocated using the kzmalloc. This comes with the limitation of maximum size of one page size(which in the x86_64 is 4Kb and 4MB for default and hugepage respectively). Somes test of igt (e.g. kms_plane@pixel-format) uses more than 4MB when testing some pixel formats like ARGB16161616 and the following error were showing up when running kms_plane@plane-panning-bottom-right*: [drm:vkms_composer_worker [vkms]] *ERROR* Cannot allocate memory for output frame. This problem is addessed by allocating the memory using kvzalloc that circunvents this limitation. V5: Improve the commit message and drop the debugging issues in VKMS TO-DO(Melissa Wen).
