Jonas 'Sortie' Termansen c0c20860ed Lots of improvements to 64-bit Sortix.

Added 64-bit system call stubs in libmaxsi.
Added a Elf64 program loader.
Fixed uninitialized memory bug in the scheduler.
x64/boot.s now takes care of user-space memory permissions.
Fixed bug in x64/syscall.s

That's right. The system now boots in 64-bit mode.

It is horribly unstable, though.

Jonas 'Sortie' Termansen 46c0cc6a12 -1 is no longer an allowed system call.
This treats a nasty bug where forking and exiting before the child
causes the kernel to panic, because the syscall -1 is run, which
just contains a trash value that happened to be 0.

The cause is still unknown. Might be the scheduler.

This won't help me sleep at night.
