The size of an omap2plus_defconfig kernel has increased by 760K - a remarkable increase that fortunately does not appear to be matched by runtime memory consumption. (Whatever caused this, it doesn't appear to have affected the N800 builds.)
The +16M runtime memory increase for the OMAP4/5 boards appears to be due to the CMA area now being accounted in highmem memory consumption.
As mentioned previously, 2420n800, 3517evm, and 4430es2panda are currently temporarily skipped.
