Move MALTA_COMMON to std.MALTA (as we have for XLP and SWARM).
This avoids universe trying to build MALTA_COMMON and fail due to
the problem addressed in r276773.
Include std.MALTA from the MALTA mipsel and MALTA64 mips64el config files,
where the machine lines exist.

Refactor common options from MALTA and MALTA64 kernel
configs into MALTA_COMMON file.

* Add a random device
* Use the same rootdev path as MALTA, so the same emulator setups
can be used with minimal fuss.

- Set proper KERNLOADADDR
- Add bpf(4) required by dhclient

o) Use ABI, not ISA_* options, to determine whether to compile bits if libkern
required for the ABI the kernel is being built for.
XXX This is implemented in a kind-of nasty way that involves including source
files, but it's still an improvement.
o) Retire ISA_* options since they're unused and were always wrong.

Use new option names for NFS client and NFS server

See UPDATING entry for 20110427

Switch the GENERIC kernels for all architectures to the new CAM-based ATA
stack. It means that all legacy ATA drivers are disabled and replaced by
respective CAM drivers. If you are using ATA device names in /etc/fstab or
other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise
with tunables, see cam(4)).

ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool
for management. Instead of /dev/arX device names, use /dev/raid/rX.

ldscript and conf cleanup for MIPS

- Remove sys/conf/ldscript.mips.64 and sys/conf/ldscript.mips.n32 and use
ldscript.mips for all ABIs. The default OUTPUT_FORMAT of the toolchain
is correct.
- Remove LDSCRIPT_NAME entires from XLR n32 and n64 conf files.
- Remove TARGET_BIG_ENDIAN from XLR conf files.
- Fix machine entry in XLRN32

Remove the 'machine mips' from DEFAULTS. Put the proper 'machine mips
mipsel' or 'machine mips mipseb' into the config file (with a few 64's
tossed in for good measure). This will let us build the proper
kernels with different worlds as part of make universe.

TARGET_64BIT isn't needed anymore, GC it (partial merge from tbemd).

Get rid of unused options: KERNPHYSADDR, KERNVIRTADDR, PHYSADDR, PHYS_ADDR_64BIT

Discussed with: gonzo, imp

Adjust style (following the already existing rules) for the newly
introduced option DEADLKRES.

Reported by: danfe, julian, avg

Add the options DEADLKRES (introducing the deadlock resolver thread) in
the 'debugging' section of any HEAD kernel and enable for the mainstream
ones, excluding the embedded architectures.
It may, of course, enabled on a case-by-case basis.

Set the svn:eol-style = native and svn:mime-type = text/plain
properties on all files in this tree.

Place proper svn:keywords tag on all these files. They were created
somehow without them on projects/mips, and that mistake was propigated
over to head.

Submitted by: rpaulo@

Using svn cp rather than cp to copy these files over had the benefit
of preserving their history. It had the problem that it also copied
over mergeinfo data. Since we're retiring the projects/mips branch,
I'm removing the svn:mergeinfo property from them all.

Merge from projects/mips to head by hand:

Copy over MALTA64, the 64-bit varianat of the malta board...

Set the ldscript for malta64 correctly.

Flag this as a 64-bit build.

# Too many flagas needed to build 64-bit, plus different endian, etc. The
# makefile is getting kinda gross with ifdefs.

Add support for compiling MALTA as mips64.

# MALTA64 builds, but doesn't link yet.
