    drm/i915: Replace a calloc followed by copying data over it with malloc. · c8e0f93a
    Eric Anholt authored
    Execbufs involve quite a bit of payload, to the extent that cache misses
    show up in the profiles here, and a suspicion that some of those cachelines
    may get evicted and then reloaded in the subsequent copy.
    
    This is still abstracted like drm_calloc_large since we want to check for
    size overflow, and because we want to choose between kmalloc and vmalloc
    on the fly.  cairo's interface for malloc-with-calloc's-args was used as
    the model.
