Evolve the ctlreq interface added to geom_gpt into a generic partitioning class that supports multiple schemes. Current schemes supported are APM (Apple Partition Map) and GPT. Change all GEOM_APPLE anf GEOM_GPT options into GEOM_PART_APM and GEOM_PART_GPT (resp). The ctlreq interface supports verbs to create and destroy partitioning schemes on a disk; to add, delete and modify partitions; and to commit or undo changes made. 2007-02-07 18:55:31 +00:00			`options GEOM_PART_GPT # GUID Partition Tables.`

Turn console printf buffering into a kernel option and only on by default for sun4v where it is absolutely required. This change moves the buffer from struct pcpu to the stack to avoid using the critical section which created a LOR in a couple of cases due to interaction with the tty code and kqueue. The LOR can't be fixed with the critical section and the pcpu buffer can't be used without the critical section. Putting the buffer on the stack was my initial solution, but it was pointed out that the stress on the stack might cause problems depending on the call path. We don't have a way of creating tests for those possible cases, so it's best to leave this as an option for the time being. In time we may get enough data to enable this option more generally. 2006-11-30 04:17:05 +00:00			`options PRINTF_BUFR_SIZE=128 # Prevent printf output being interspersed.`
Enable AUDIT by default in the GENERIC kernel, allowing security event auditing to be turned on without a kernel recompile, just an rc.conf option. Approved by: re (kensmith) Obtained from: TrustedBSD Project 2007-06-08 20:29:07 +00:00			`options AUDIT # Security event auditing`
