Here are some basic Tegra test results for Linux v3.18-rc1. Logs and other details at:

The 64MiB decrease in highmem is a bit mysterious. Am thinking that it is probably PCIe-related, given the PCIe messages in the boot logs:

Looks like we also have some PL310 DT work to do:
+PL310 OF: cache setting yield illegal associativity +PL310 OF: 0 calculated, only 8 and 16 legal
Also the Cortex-A15 boards are no longer using the ARM localtimers:
