src/sys/arch/aarch64/aarch64: aarch64_machdep.c
Log Message:
Two fixes for loading free pages into UVM
- Only consider a boot_physmem (inner loop) range that has its end
(bp_end) after the bootconfig.dram (outer loop) range start (start).
This was harmless as a later condition correctly checks there is only
something to do if start < bp_end.
- Stop processing boot_physmem ranges if all the bootconfig.dram range has
been passed to UVM. This fixes a boot problem for simon@
