There are a lot of under the hood changes here: - Move syscalls to be a dispatch table, defined by syscalls.inc - Don't need a full process state (push_all) in syscalls now - In push_all, define REGS instead of using offsets - Save TWO stack pointers as well as current saved stack pointer in TCB: - rsp0 is the base of the kernel stack for interrupts - rsp3 is the saved user stack from cpu_data - Update syscall numbers in nulldrv - Some asm-debugging enhancements to the gdb script - fork() still not working
