- hold/release device in start/done routines, this will probably slow
down things a bit, but previous code was racy;
- only release device if g_gate_destroy() failed - if it succeeded device
is dead and there is nothing to release;
- various other changes which makes forcible destruction reliable.

- Make the PROBE_KEYBOARD option better resemble the -P option in
boot2, i.e., if keyboard isn't present then boot with both
RB_SERIAL and RB_MULTIPLE set.

any threads to them. However, it still counts those cores as "active but
permanently idle" when calculating system-wide CPUs statistics. It is
incorrect, since it skews statistics quite a bit and creates real problems
for certain types of applications (monitoring applications for example),
by making them believe that the system does have enough idle CPU resources,
while in fact it does not.
Correct the problem by not calling performance counting routines on "disabled"
cores. The cleaner solution would be to just disable APIC timer interrupts on
those cores completely, but ENOTIME here and it is not clear if the
additional complexity really worth minor performance gain.

we can find another way to issue an #error, but using a preprocessed
assembler for that purpose and clobbering libc.a with an empty .o
just for the sake of #error reporting is way too much of a burden.
* Expose functions for setting the "skip file" dev/ino information
* Expose functions for setting/querying the block size on reads
* Correctly propagate errors out of archive_read_close/archive_write_close
* Update manpage with information about new functions
the "device isa" presence out of the opt_isa.h in the kernel
build directory, rather than always assuming its presence.
sparc64 is still special cased and is not affected by this

This helps systems that don't actually have atkbd controllers, such as the Intel
SBX82 blade, boot without device.hints hacks.

for a bit before retrying to resend an IPI in order to avoid
deadlocks if the other CPU is also trying to send one.
OpenSolaris uses a delay of 1 microsecond here but waiting 2
microseconds with interrupts enabled like Linux does shouldn't
hurt but is a bit safer.
