from doc/BRANCHES:

	idle lwp, and some changes depending on it.

	1. separate context switching and thread scheduling.
	   (cf. gmcgarry_ctxsw)

a7afe56d70 Fix polyd trapping when running pic and grn during groff tool builds on 
vax.  From OpenBSD:

Addressing mode work by Jim Uhl:
    - fix PC relative byte displacement in getaddr_byte
    - add support for word displacement to getaddr_byte

This allows certain libm inverse trig functions to work on systems
that lack a native polyd instruction.

ef1bc24053 Link the boot loader for address 4M-64k, as requested by Hans Rosenfeld. 
It's not likely that a vax has less than 4MB of memory today, if someone
has a small-memory-machine he have to recompile boot himself.

c147748d84 - Make the proclist_lock a mutex. The write:read ratio is unfavourable, 
and mutexes are cheaper use than RW locks.
- LOCK_ASSERT -> KASSERT in some places.
- Hold proclist_lock/kernel_lock longer in a couple of places.

4410329b87 add a pair of new bus_dma(9) functions: 
int _bus_dmatag_subregion(bus_dma_tag_t tag,
				  bus_addr_t min_addr,
				  bus_addr_t max_addr,
				  bus_dma_tag_t *newtag,
				  int flags)
	void _bus_dmatag_destroy(bus_dma_tag_t tag)

that allow a (normally broken/limited) device to restrict the bus address
range it can talk to.  this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.

all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several
people on tech-kern.

XXX: bus_dma(9) needs an update still.

934634a18c Change the process/lwp flags seen by userland via sysctl back to the 
P_*/L_* naming convention, and rename the in-kernel flags to avoid
conflict. (P_ -> PK_, L_ -> LW_ ). Add back the (now unused) LSDEAD
constant.

Restores source compatibility with pre-newlock2 tools like ps or top.
