sparc32: Kill trap table freeing code.
Normally, srmmu uses different trap table register values to allow determination of the cpu we're on. All of the trap tables have identical content, they just sit at different offsets from the first trap table, and the offset shifted down and masked out determines the cpu we are on. The code tries to free them up when they aren't actually used (don't have all 4 cpus, we're on sun4d, etc.) but that causes problems. For one thing it triggers false positives in the DMA debugging code. And fixing that up while preserving this relative offset thing isn't trivial. So just kill the freeing code, it costs us at most 3 pages, big deal... Signed-off-by: David S. Miller <email@example.com>
