Nexoniarz 1ba93dde2c kernel: syscalls get the whole kernel stack 
syscall_entry put the frame at kstack + 4096 - 16, from when a kernel
stack was one page. It has been two since, so every syscall ran in the
bottom 4 KB while traps used the top, and a deep enough read -- startx
exec'ing through the new compressed ramdisk -- ran over the canary at
kstack[0]. The frame now sits at the top of KSTACKSIZE, where allocproc
and the TSS already put it, and exec's user-rsp slot moves with it.
