	myself it is right either

2006-09-06	standardize various * conventions	rsc

2006-08-10	interrupts could be recursive since lapic_eoi() called before rti	rtm
	so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi()
2006-07-18	prevent longjmp / forkret from writing over tf->edi	rtm

2006-07-15	no more recursive locks	rtm
	wakeup1() assumes you hold proc_table_lock sleep(chan, lock) provides atomic sleep-and-release to wait for condition ugly code in swtch/scheduler to implement new sleep fix lots of bugs in pipes, wait, and exit fix bugs if timer interrupt goes off in schedule() console locks per line, not per byte
2006-07-12	no more big kernel lock	rtm
	succeeds at usertests.c pipe test
2006-07-01	swtch saves callee-saved registers	rtm
	swtch idles on per-CPU stack, not on calling process's stack fix pipe bugs usertest.c tests pipes, fork, exit, close
2006-06-27	file descriptors	rtm
	pipes
