- Remove XD bit in page tables
- Fix cylinder+head+sector arithmetic
- Implement fstat() for serial file descriptors on metal
Here's how to boot an Actually Portable Executable in QEMU:
make -j12 o//tool/viz/deathstar.com
qemu-system-x86_64 -serial stdio -fda o//tool/viz/deathstar.com
Here's a screenshot of DEATHSTAR.COM booted in QEMU:

Thus metal support is in much better shape now, but still incomplete.
Only a few system calls have been polyfilled. To figure out which ones
your program needs, simply boot it in the blinkenlights emulator with a
breakpoint, and press CTRL-C to continue to the system call breakpoint.
If it doesn't break then you should be good. (Note: to emulate normally
you can press 'c' and use CTRL-T and ALT-T to tune the speed.)
m=tiny
make -j12 SILENT=0 MODE=$m \
o/$m/tool/build/blinkenlights.com \
o/$m/tool/viz/deathstar.com
o/$m/tool/build/blinkenlights.com \
-r -t -b systemfive.linux \
o/$m/tool/viz/deathstar.com
Thank @Theldus for the bug report that made this change possible.
Fixes #20 which explains this change further.
