Hurrah,
I was curious about the huge kernel images, and had it on my list to poke at. Adrian's changes merged last night sorted it:
x86: Explicitly declare adress of .phys.bss
x86: Add BSS regions for BOOT and PHYS code
Simulation debug x86_64 image is down from 7.1M to 1.1M. That's more like it!
Nice! :-)
Thanks,
Jeff
