To Artifact [298efe4468]:
- File mod/kcore/boot.rt.c — part of check-in [62fd1bfe97] at 2020-01-05 17:52:15 on branch trunk — Fix _start to properly find the environment. The arguments and environment are directly on the initial stack, which means that more work is needed to find the start of the environment properly. Also remove the hack in _boot that made it work if there were no arguments, as all of the math is being done in _start now. (user: glowpelt, size: 1097) [annotate] [blame] [check-ins using]
