There is a buffer overflow in printint function which can be triggered if numbers with more than 16 digits are written to the terminal. Numbers 18446744073709551615 and -9223372036854775808 both have 20 digits for instance. To this extent, I increased the buffer size to 20 characters which can fit base 10 of all 64 bit numbers (negative or positive).

interrupts. I recently got a panic caused by this (process moved to a different core between mycpu() and ->noff). also, make panic msg printing more robust if mycpu()->noff or locks are broken.
sbrk() is the eager version Speedup countfree() by using eager allocation Simplify some usertests by using eager allocation
sbrk already uses it
no more typing 0xffffffffffffffffLL
kernel sys_sleep() -> sys_pause() kernel fork() -> kfork() kernel exec() -> kexec() kernel wait() -> kwait() kernel exit() -> kexit() kernel kill() -> kkill() SYS_sleep -> SYS_pause
