Use 'sysmsg_result' macro for consistency

Don't directly use the 'sm_result' union member in 'struct sysmsg',
consistent with other kernel code.

kernel: Add 'static' to some function definitions.

The declarations already have it, so no functional difference.

kernel - Cleanup gcc warnings

* Cleanup gcc warnings at higher optimization levels. This will allow
us to build kernels -O2 or -O3.

kernel: Use the new auto-created sysctl ctx/tree in various drivers.

Everywhere where we formerly rolled a hw.fooX.* per-device ctx/tree
ourselves.

This commit switches it to dev.foo.X.*

Use C99 __func__ instead of __FUNCTION__.

kernel/amr: Extend the visibility of AMR_DEBUG.

Half the code was missing the setting of AMR_DEBUG in the config file
because its visibility was reduced to amr.c only.

kernel: Remove some unused variables in RAID and disk drivers.

amr(4): Remove some unused code (amr_timeout()).

Taken-from: FreeBSD

amr(4): Remove an extra newline in a debug message.

amr(4): Make AMR_DEBUG a kernel configuration option.

kernel: Add descriptions to the intrhooks that miss them.

The description is printed in the

"**WARNING** waiting for the following device to finish configuring: ..."

kernel: Add descriptions to the intrhooks that miss them.

The description is printed in the

"**WARNING** waiting for the following device to finish configuring: ..."

messages we occasionally see, from run_interrupt_driven_config_hooks(),
most of the times for xpt.

Some of them had been accidentally removed in past synchronizations with
FreeBSD (mostly by me).

amr(4): Remove unused code.

amr(4): Some fixes.

* Bring in some small updates from FreeBSD.

* Add MODULE_VERSION.

* Make the interrupt handler MPSAFE. This was a porting oversight by me.

kernel: Remove some bogus casts of NULL to something.

kernel: Remove newlines from the panic messages that have one.

panic() itself will add a newline.

kernel: Remove unused attributes from stuff that is, in fact, used.

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

Silence warnings about unhandled enum values.

If ae is NULL, just print that the controller is unsupported and return,
instead of continuing and dereferencing it later.

Flesh out BUF_CMD_FLUSH support.

Remove bogus checks after kmalloc(M_WAITOK) which never returns NULL.

* The diskslice abstraction now stores offsets/sizes as 64 bit quantities.
(NOTE: DOS partition tables and standard disklabels can't handle 64 bit
sector numbers yet). For future pluggable disklabel/partitioning schemes.

* The kernel panic / kernel core API is now 64 bits.

* The VN device now uses 64 bit sector numbers and can handle block devices
up to what is supported by the filesystem (typically 8TB). This change
was made primarily so we can test future disklabel / partition table
support.

* Pass 64 bit LBAs to various block devices and to the SCSI layer.

* Check for and assert 32 bit overflow conditions in various places, instead
of wrapping.

Do a major clean-up of the BUSDMA architecture. A large number of
essentially machine-independant drivers use the structures and definitions
in machine-dependant directories that are really machine-independant in
nature.

Split <machine/bus_dma.h> into machine-depdendant and machine-independant parts
and make the primary access run through <sys/bus_dma.h>.

Remove <machine/bus.h>, <machine/bus_memio.h> and <machine/bus_pio.h>. The
optimizations related to bus_memio.h and bus_pio.h made a huge mess,
introduced machine-specific knowledge into essentially machine-independant
drivers, and required specific #include file orderings to do their job.
They may be reintroduced in some other form later on.

Move <machine/resource.h> to <sys/bus_resource.h>. The contents of the file
is machine-independant or can be made a superset across many platforms.

Make <sys/bus.h> include <sys/bus_dma.h> and <sys/bus_resource.h> and
include <sys/bus.h> where necessary. Remove all #include's of
<machine/resource.h> and <machine/bus.h>. That is, make the BUSDMA
infrastructure integral to I/O-mapped and memory-mapped accesses to devices
and remove a large chunk of machine-specific dependancies from drivers.
bus_if.h and device_if.h are now required to be present when using <sys/bus.h>.
