	better parsing of sh commands (copied from jos sh) cat: read from 1 if no args sbrk system call, but untested getpid system call moved locks in keyboard intr, but why do we get intr w. null characters from keyboard?
2006-08-19	chdir	kaashoek	1	-2/+2
	cd in shell nits in mkdir, ls, etc.
2006-08-15	no more proc[] entry per cpu for idle loop	rtm	1	-39/+30
	each cpu[] has its own gdt and tss no per-proc gdt or tss, re-write cpu's in scheduler (you win, cliff) main0() switches to cpu[0].mpstack

2006-08-13	link()	rtm	1	-3/+0

2006-08-10	interrupts could be recursive since lapic_eoi() called before rti	rtm	1	-2/+14
	so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi()
2006-08-08	fix race in holding() check in acquire()	rtm	1	-4/+6
	give cpu1 a TSS and gdt for when it enters scheduler() and a pseudo proc[] entry for each cpu cpu0 waits for each other cpu to start up read() for files

2006-07-17	nitpicks	rsc	1	-1/+1

2006-07-16	Eliminate annoying Pseudodesc structure.	rsc	1	-4/+3
	Eliminate unnecessary parts of mmu.h.
2006-07-16	standardize on not using foo_ prefix in struct foo	rsc	1	-11/+11

2006-07-16	Rename fd_reference to more suggestive fd_incref.	rsc	1	-1/+1
	(Fd_reference sounds like it might just return the ref count.)
2006-07-16	Attempt to clean up newproc somewhat.	rsc	1	-51/+67
	Also remove all calls to memcpy in favor of memmove, which has defined semantics when the ranges overlap. The fact that memcpy was working in console.c to scroll the screen is not guaranteed by all implementations.
