 9	  Write kernel log output directly via the hypervisor console.

11	  This is useful for kernel debugging when your machine crashes very
12	  early before the console code is initialized. For normal operation
13	  it is not recommended because it looks ugly and doesn't cooperate
14	  with klogd/syslogd. You should normally N here,
15	  unless you want to debug such a crash.

20	help
21	  This option will cause messages to be printed if free stack space
22	  drops below a certain limit.

27	default ""
28	help
29	  Debug info can be large, and flags like
30	  `-femit-struct-debug-baseonly' can reduce the kernel file
31	  size and build time noticeably.  Such flags are often
32	  helpful if the main use of debug info is line number info.
