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. This problem is addessed by allocating the memory using kvzalloc that circunvents this limitation.
