ok, I got lost in the maze of macros.
128 bytes is a pretty small amount of stack though, so I'm just as confused
as to what the actual bug here is.
After trying the proposed fix, I got another oops in the early init code..
<trace>
nr_free_zone_pages
nr_free_pagecache_pages
build_all_zonelists
start_kernel
<rip> ffffffffbc164b1e next_zones_zonelist
<rsp> ffffffffbcc01f00
I'll poke at it more in the morning. Too sleepy.
