their prototypes.
- Remove sched_lock locking from kse_purge() as all callers already lock
the sched_lock before calling it.
- Hold the proc lock slightly longer to protect P_SHOULDSTOP().

XXX: vinum should really be using a kernel process via kthread_create()
instead of this hack. I'm not even sure PS_INMEM can be clear at this
point anyways.
kern_sigprocmask() in the various binary compatibility emulators.
- Replace calls to sigsuspend(), sigaltstack(), sigaction(), and
sigprocmask() that used the stackgap with calls to the corresponding
kern_sig*() functions instead without using the stackgap.
OBJS list. This is needed to crunch any program that relies on the
correct .CURDIR setting, e.g. src/bin/csh.

cpu_switch_load_gs, cpu is in context switch, so don't enable interrupt.
because it is in context switch, it is expected sched_lock was held,
so don't PROC_LOCK(p) and psignal, it is LOR, probably we can
set a P_XSIGBUS like flag in p_sflags, and set TDF_ASTPENDING in
td_flags, in ast(), post a SIGBUS to process if P_XSIGBUS was set.
called without Giant; and obj_alloc() in turn calls vm_page_alloc()
without Giant. This causes an assertion failure in vm_page_alloc().
Fortunately, obj_alloc() is now MPSAFE. So, we need only clean up
some assertions.
- Weaken the assertion in vm_page_lookup() to require Giant only
if the vm_object isn't locked.
- Remove an assertion from vm_page_alloc() that duplicates a check
performed in vm_page_lookup().
In collaboration with: gallatin, jake, jeff
instruction requires that a translation is present in the TC. This
may trigger a TLB miss and a subsequent call to vm_fault().
This implementation is deliberately non-inline for debugging and
profiling purposes. Partial or full inlining should eventually be
done.

separate man page. Document new device_is_attached there and remove that
new man page too.
Connect device_get_name to build, and install a link for
device_get_nameunit.
strangely nobody noticed this yet...
PC98 boot blocks don't support UFS2. We keep newfs(8) defaulting to
UFS2.
Warn users that FreeBSD can only boot from a root file system smaller
than 1.5TB; hopefully this will get fixed by the patches currently
floating around on -CURRENT.

This means that you can no longer trash your opened partitions by writing to
the sunlabel through another partition. This is similar to the semantics
implemented for BSD labels.
and this manpage is somewhat machine independent.
- Don't redundantly say that SMP support is present for all supported
architectures. Instead, say that it is present for all Tier-1
architectures.
- Note that an SMP kernel not booting on a UP machine is an i386-only
exception.
- Add a paragraph about hyperthreading support including some docco on the
machdep.hlt_logical_cpus sysctl ps@ recently added.
- Note that SMP support for alpha, ia64, and sparc64 debuted in 5.0.
if attach succeeded. device_is_alive just tells us that probe
succeeded. Since we were using it to do things like detach net
interfaces, this caused problems when there were errors in the attach
routine.
