Module Name: src
Committed By: reinoud
Date: Thu Sep 15 12:23:51 UTC 2011
Modified Files:
src/sys/arch/usermode/include: thunk.h
src/sys/arch/usermode/usermode: thunk.c
Log Message:
Implement a dprintf_debug() analog to aprint_debug() but printing it to stderr
using vdprintf() to bypass the kernel buffer. It is currently printing only on
the -x boot flag but might get a more specific one since its quite verbose!
