r228476 fixed superfluous link UP/DOWN messages but broke IPMI
access during boot. It's not clear why r228476 breaks IPMI and
should be revisited.

Replace them with a single uart_cpu_x86.c.
o delete uart_cpu_i386.c

o update files.amd64 and files.i386 accordingly.

are used across threads, multiple threads can end up with the same TLS base.
Madness will then result.
This makes behavior on PPC match that on x86 systems and on Linux.

compatibility, it broke programs using devstat, under 32-bit compatibility and
not.
It's very difficult to fix the identifiers used by devstat, so this change is
simply being backed out. Since changes to 3rd-party code seem likely, and may be
necessary to properly fix 32-bit binaries on 64-bit kernel, it would seem better
to make more invasive changes to fix GEOM's problems with 32-bit compatibility in
general.
The right thing to do is to replace all of the use of pointers as opaque
identifiers with a fixed-size (64-bit or even 32-bit should be enough for tracking
unique GEOM elments) field. That probably maintains source compatibility with
most GEOM consumers, and allows xml2tree to make better assumptions about how to
decode the identifiers.

add a FreeBSD_version check. It should work fine for compiling

* Conditionally compile the 11n options only when 11n is enabled.
The above changes allow the ath(4) driver to compile and run on
8.1-RELEASE (Hi old PC-BSD!) but with the 11n stuff disabled.
I've done a test against the net80211 and tools in 8.1-RELEASE.
The NIC used in testing is the AR2427 in an EEEPC.
Just to be clear - this change is to allow the -HEAD ath/hal/rate
code to run on 9.x _and_ 8.x with no source changes. However,
when running on earlier kernels, it should only be used for legacy
mode. (Don't define ATH_ENABLE_11N.)
this commit is not enough to enable CARP operation on

called in the !SMP case too.
Fix this by:
- Adding the BSP as an interrupt target directly in cpu_startup().
- Remove an obsolete optimization where the BSP are skipped in
set_apic_interrupt_ids().

If the named semaphore is already open, sem_open() only increments a

happens by passing them to open()). Add an extra check for O_CREAT|O_EXCL.
