Also unhide an error message from bootverbose, this would help to
easier determine the problem.
with geometry. And they do recalculation of user specified parameters.
MBR, PC98, VTOC8, EBR schemes are doing that. For these schemes an
auto alignment feature (ie. gpart add -a alignment) would not work.
But it can work for GPT and BSD schemes. BSD scheme usualy is created
inside MBR, so we can use knowledge about offset of MBR partition to
calculate aligned values for BSD partitions.
Use "offset" attribute of the parent provider for better alignment.

- Add shorthand aliases for common media+option combinations as announced
by miibus(4) so that one can actually supply the media strings found in
the dmesg output to ifconfig(8).

clear the options of the current media, i.e. only inherit the instance,
which matches what NetBSD does. Without this it's really non-intuitive
that the following sequence:
ifconfig bge0 media 1000baseT mediaopt full-duplex
ifconfig bge0 media 100baseTX
results in 100baseTX full-duplex to be set or that:
ifconfig bge0 media autoselect mediaopt flowcontrol
ifconfig bge0 media 1000baseT mediaopt full-duplex
tries to set 1000baseT full-duplex with flowcontrol, which isn't suported
und thus fails while the following:
ifconfig re0 media 1000baseT mediaopt flowcontrol,full-duplex
ifconfig re0 media autoselect
just switches to autoselection without flowcontrol.

The other queues, especially the command queue, uses the FIFO mode
which doesn't require the byte count table because queued entries are
processed in order.

Since the returned NF will be -ve, checking for <= 0 is not good
enough. For now, check whether it equals 0 or -1; a future commit
will tidy this mess up and have it return HAL_BOOL instead.

Allow the usage of a private address and make sure

because we need to do ioctl(2)s, which are not permitted in the capability
mode. What we do now is to chroot(2) to /var/empty, which restricts access
to file system name space and we drop privileges to hast user and hast
group.
This still allows to access to other name spaces, like list of processes,
network and sysvipc.
To address that, use jail(2) instead of chroot(2). Using jail(2) will restrict
access to process table, network (we use ip-less jails) and sysvipc (if
security.jail.sysvipc_allowed is turned off). This provides much better
separation.

The eeprom Get method should return HAL_OK if fastclock is enabled in the
EEPROM. It was returning the opposite of what it should have.
Submitted by: Matthew Fleming <mdf356@gmail.com>
The code assumed it could return HAL_OK, HAL_EINVAL and other
HAL_STATUS types; so it shouldn't be declared as returning HAL_BOOL.

the register stack. While the ordering doesn't matter, it creates an
invariant not previously there: the memory stack pointer will always be
larger than the register stack pointer. With this invariant in place,
it's easier to add instrumentation code that detects a stack overflow
because in such a scenario the memory stack pointer and register stack
pointers have crossed each other.
Aside: basic kernel operation needs about half the stack size (~16K)
at most. We have plenty of head room on the kernel stack...
o Clobber the register that holds the restart token immediately after
crossing the restart point. This prevents false positives (i.e. a
nested exception that we don't know can happen and that is being
treated as one we know by virtue of a lingering restart token).
o Now that the bootstrap kernel stack is free, switch onto it and call
trap() for nested traps that we don't know about. In trap we panic()
so that we can analyze the condition.
I've tested this locally and it does indeed read and attach to an AR9287
EEPROM. But a lot more code needs to be ported over to the HAL before
the AR9287 is functional.
I'm importing this separate from the rest of the codebase (and unlinked from
the build for now) in case someone wishes to begin fiddling with porting
the rest of the code over from Linux ath9k.

Now that printf(1) is a shell builtin, there is no need to emulate it
anymore. The external printf(1) is /usr/bin/printf and therefore may not be
available in early boot.
It may be faster to use printf directly but the function is useful for
compatibility.
flags are also specified. This change makes use of this behaviour and removes
unneeded -mno-* flags.
Note that clang does not yet enable AVX support for any CPU. However at some
point in the future it will and since we definitely want to disable it for the
kernel, we might as well add the -mno-avx flag now.

is totally disabled.
The Atheros HAL code does this for Sowl/Howl but not for Owl (AR5416) where
RIFS is disabled by default.
This seems to quieten the occasional baseband hang I've been seeing with
the AR9160 in STA mode under constant heavy traffic load.
