Also use __DEFAULT_DEPENDENT_OPTIONS for options that
generally depend on META_MODE.
Deal with MK_META_MODE and MK_AUTO_OBJ directly.
Also allow MK_META_FILES if no -B
this is very handy for getting meta files from say buildworld
By moving META_MODE bits from local.sys.mk, they are easier
to skip when MK_META_MODE=no
Update some filters to cope with sync from head.
If buildworld etc or WITHOUT_META_MODE disable all the META_MODE
related options.
In smp_rendezvous_cpus we expect to wait for all cpus to enter
smp_rendezvous_action. If we call this holding a proc lock swapper may
attempt to also lock it, however as interrupts are disabled the cpu never
handles the ipi. Because smp_rendezvous_action waits for all signaled
cpus before contining it may get caught waiting for the cpu running swapper
as the proc mutex will be unlocked after smp_rendezvous_cpus finishes.
The fix is to enable interrupts in the configure stage as we should be
doing.

to sleep while it waits to start scheduling. The boot core can then use
the send-event instruction to wake the cores when they should enter the
scheduler.

so that it would not return less data than requested.
Since returning less directory data than requested is not a problem
for FreeBSD and even UFS no longer returns directory structures
with d_fileno == 0, this patch stops the client from doing this.
Although entries with d_fileno == 0 should not be a problem,
the man pages no longer document that these entries should be
ignored, so there was a concern that these entries might be an
issue in the future.

stopping signals should obey, but also all forms of single-threading.
Otherwise, thread might sleep interruptible while owning some
resources, and single-threading thread could try to access them.
An example is owning vnode lock while dumping core.

when allocation fails, it suffices to perform VM_WAIT. The direct map
covers the entirely of physical memory, so unlike 32-bit mips any
physical page can be used as a page table page.
ieee80211_pwrsave() can fail due to queue overflow, check its return code
and increment oerrors counter when it fails. Also handle more error cases
and update oerrors counter when we don't send mbuf due to some errors.
Return ENETDOWN when parent interface isn't ready. Update obytes and omcasts
counters in corresponding places.
