Here are a few miscellaneous MIPS fixes, which were mostly found by running an up to date KVM guest kernel. Patch 1 fixes the fixmap address for KVM guests, which was never updated to reside in USEG. Patch 2 fixes a bug in the XPA patches, which seems to manifest in KVM guests in particular (for unclear reasons). Patch 3 makes a tweak related to patch 2. (Steven's review of these two patches in particular would be appreciated). Finally patch 4 enables ZONE_DMA32 on 64-bit Malta kernels to prevent exhaustion of the 16MiB DMA zone being a problem (try enabling KVM_PROVE_LOCKING in a recent kernel).
