    drm/lima: Fix lima cache creation · 15b43d77
    Andreas Baierl authored
    Due to the kernel merge of the hardened usercopy patch set
    we have to whitelist the memory area which is used for
    copy_from_user actions. Otherwise lima fails with an abort
    and segmentation fault.
    
    This is necessary on systems with CONFIG_HARDENED_USERCOPY enabled.
    It was tested on a Cubieboard 1, Allwinner A10.
