Ivan Kokshaysky 98c532ecbe alpha: use single HAE window on T2 core logic (gamma, sable) ... T2 are the only alpha SMP systems that do HAE switching at runtime, which is fundamentally racy on SMP. This patch limits MMIO space on T2 to HAE0 only, like we did on MCPCIA (rawhide) long ago. This leaves us with only 112 Mb of PCI MMIO (128 Mb HAE aperture minus 16 Mb reserved for EISA), but since linux PCI allocations are reasonably tight, it should be enough for sane hardware configurations. Also, fix a typo in MCPCIA_FROB_MMIO macro which shouldn't call set_hae() if MCPCIA_ONE_HAE_WINDOW is defined. It's more for correctness, as set_hae() is a no-op anyway in that case.
