[Mesa-dev] [PATCH 3/7] i965: Don't map/unmap in brw_print_program_cache on LLC platforms.

[Kenneth Graunke]

We have a persistent mapping.  Don't map it a second time or try to
unmap it.  Just use the pointer.

This most likely would wreak havoc except that this code is unused
(it's only called from an if (0) debug block).
