Module Name: src
Committed By: thorpej
Date: Wed Jul 20 18:25:10 UTC 2022
Modified Files:
src/sys/arch/alpha/alpha: locore.s
Log Message:
Fix a couple of nits with savectx():
- Note that this function is only used by dumpsys().
- Don't safe the PS word; there isn't actually a spot for it in the PCB.
- Don't bother returning anything; savectx() is declared void.
