a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc. This
is because the kernel linker only searches for symbols in dependent modules,
so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc
was not compiled into the kernel (even if you hand-loaded mmc first).
(Thanks to jilles@ for providing the vital clue about the kernel linker.)
ahci.c had one signed long, which was passed into rman, rather than u_long.
After the switch of rman_res_t from size u_long to size uintmax_t, the sign
extension caused ranges to get messed up, and ahcich* to not attach.
There may be more signed longs used in this way, which will be fixed as they're
reported.

1. Limit secs to INT32_MAX / 2 to avoid errors from kern_setitimer().
Assert that kern_setitimer() returns 0.
Remove bogus cast of secs.
Fix style(9) issues.
2. Increment the return value if the remaining tv_usec value more than 500000 as a Linux does.

There's some upcoming work to add new chipset support here and I'd
like to only add 802.11n support to one driver, instead of both
urtwn and rtwn.
There's also missing support for things like 802.11n, some powersave
work, bluetooth integration/coexistence, etc, and also newer parts
(like 8192EU, maybe some 11ac parts, not sure yet.)
So, this is hopefully the first step in a longer set of steps to unify
rtwn/urtwn and extend it with more interesting chipset and functionality
support.

Illumos recently included space in 'print' class. We already had
this but the code had slight sorting differences. Move it some
lines up to reduce diffs with Illumos.
No functional change.

meta mode, treat missing reads as for writes.
Update dirdeps.mk - much improved startup time.
Update meta.stage.mk - avoid ln when chmod required.
An IPI cannot be sent via the local APIC if a previous IPI is still
being delivered. Attempts to send an IPI will wait for a pending IPI
to clear. Prior to r278325 these checks used a spin loop with a
hardcoded maximum count which broke AP startup on some systems.
However, r278325 also enforced a minimum latency of 5 microseconds if an
IPI was still pending which resulted in a measurable performance hit.
This change reduces that minimum latency to 1 microsecond.

For the !unmap case it may happen that pbuf gets called unreferenced
when vm_fault_quick_hold_pages() fails.
Initialize it so it doesn't cause trouble.

This is a subset of what's in the linux 802.11ac implementation.
I've verified that the bits that mention an 802.11ac draft are
still the same in 802.11ac-2013 and noted it accordingly.
This is for the most part one big no-op.
