Marius Strobl db3a488fb0 In order to save instructions the MMU trap handlers assumed that the kernel ... TSB is located within the 32-bit address space, which held true as long as we were using virtual addresses magic-mapped before the location of the kernel for addressing it. However, with r216803 in place when possible we address it via its physical address instead, which on machines like Sun Fire V880 have no physical memory in the 32-bit address space at all requires to use 64-bit addressing. When using physical addressing it still should be safe to assume that we can just ignore the lowest 10 bits of the address as a minor optimization as we did before r216803.		2011-01-17 20:32:17 +00:00
