Module Name: src
Committed By: kamil
Date: Tue Dec 13 13:09:00 UTC 2016
Modified Files:
src/tests/kernel/arch/amd64: t_ptrace_wait.c
Log Message:
Remove dbregs* in arch/amd64/t_ptrace_wait*
CPU Debug Registers won't be exposed as is to userland.
Hardware Watchpoints will be exported to userland dedicated interface
through the ptrace(2) interface.
