implementations for each of the chips we support. Most chips up through
armv6 can use the armv4 implementation which has a single coprocessor
opcode for this operation. The rather more complex armv7 implementation
comes from netbsd.
- Support for double-tap and drag.
- Support for 2-finger horizontal scrolling which translates to page-back/forward events.
- Single finger tap is equivalent to a left-button press.
- Two-finger taps are mapped to the right-button click.
- Three fingers are mapped to middle button.
- Add sysctl to disable single finger tapping.
- Fix for multiple open of /dev/atp0
- Enhanced support for the Fountain/Geyser family by adding Geyser4.
- Update manual page.

SPARC: Implement TRAP lowering. Matches what GCC emits.
This lets clang emit "ta 5" for trap instructions on sparc64, instead of
emitting a call to abort(), making it possible to link the kernel.
While this is technically more correct, I don't think it much matters,
because the only thing in the tree that calls cpu_flush_dcache() is md(4)
and I'm > 99% sure it's bogus that it does so; md has no ability to do
anything that can perturb data cache coherency.
it into a bunch of different .c files. Remove declarations for the unused
mptramp() function from everywhere except AramadaXP (and I think it's
really not used there either, because the code that references it appears
to be insanely does-nothing in nature).
these binaries aren't immediately useful on other MIPSes, still build them
as part of mips64 world in order to expose them to tinderbox.

a 64-bit architecture, rather than trying to share the 32-bit MIPS ficl
configuration.
When building ficl on MIPS, don't conflate 32-bit and 64-bit ISAs -- unlike
x86, we don't want a 32-bit loader on a 64-bit CPU. Use quite conservative
code generation -- e.g., softfloat, no GOT, etc -- suitable for early boot.

UCL is heavily infused by nginx configuration as the example of a convenient
configuration system. However, UCL is fully compatible with JSON format and is
able to parse json files.
UCL is used by pkg(8) for its configuration file as well for the manifest format
in packages, it will be used in base for the pkg boostrap (signature checking
and configuration file parsing.)

-mcmodel=large, for now. While here, disable -msoft-float for clang
since it is not supported, and add -fno-dwarf2-cfi-asm to stop it from
emitting .cfi directives, which GNU as does not support.
WANDBOARD.common config, but with the freescale-specific optons and devices
all together at the bottom now. In addition to reformatting and shuffling
lines around, two new options are added because they're now known to work,
VFP and FREEBSD_BOOT_LOADER.
This config does not include any static DTB, it requires that u-boot
provide a DTB (or a custom kernel config can compile one in).
This will supercede all the existing WANDBOARD* configs, but those will
be left around for a while to help people transition their customized
configs to include this new one instead.
The name is taken from the u-boot env vars fdtfile or fdt_file. If the
name isn't fully-qualified a search is done in module_path locations.
The search order for a usable dtb in fdt_setup_fdtp() is now
- A dtb loaded with an explicit "load -t dtb" command.
- A dtb already loaded into memory somehow[*] and pointed to by fdt_to_load.
- A dtb in the memory pointed to by the u-boot env vars fdtaddr or fdt_addr.
- A file named by the u-boot env vars fdtfile or fdt_file.
- A static dtb compiled into the kernel.
* Presumably by some arch-specific command or code.
The ext4 developers tend to tag Ext4-specific flags as
"incompatible" even when such features are not relevant for
read-only support. This is a consequence of the process
though which this filesystem is implemented without design
and the fact that some new features are not extensible to
ext2/3.
Organize the features according to what we support and sort
them so that we can now read-only mount filesystems with
some features that may be found in newly formatted ext4 fs.

arguments from type,filename to filename,type to be consistant with other
public file_whatever() functions, and change it to return a pointer to
the preloaded_file struct describing the file. Adjust existing callers.
The old code basically said it was going to use some particular blob
without knowing whether it could successfully do so, then it would invoke
the function to do that and return its status. If it failed, you were
done, even if other blobs might be available. Now the code attempts to use
some particular blob and if that succeeds it says so and returns success,
otherwise it moves on to try another potential blob.
One specific problem this solves is when u-boot sets an fdtaddr variable
to point to some memory address, then doesn't actually load a blob at
that address. Now the header check will fail, and the code will move
on to the fallback dtb compiled into the kernel (if any).
processor family to determine if the workaround for AMD Family 10h Erratum
383 should be enabled. To enable virtual machine migration among a
heterogeneous collection of physical machines, the hypervisor may have
been configured to report an older processor family with a reduced feature
set. Effectively, the reported processor family and its features are like
a "least common denominator" for the collection of machines.
Therefore, when the kernel is running in a virtual machine, instead of
relying upon the processor family, we now test for features that prove
that the underlying processor is not affected by the erratum. (The
features that we test for are unlikely to ever be emulated in software
on an affected physical processor.)

If a "loaderdev=<device>" env variable is set and the named device
exists, it is used. If the device doesn't exist, fall back to the
historic "probe" loop that prefers disk devices over network devices.
If the env var is not set, preserve the historic behavior of using the
first working disk device provided by u-boot, or a network device if no
functional disk device is found and a network device exists.
The old probe loop is reworked so that it checks all bootable devices
provided by u-boot rather than taking an early-out on the first device
found. This results in the cosmetic change of listing all potential boot
devices for the user, but the behavior of which device it chooses is the
same as it has always been.
Some modules do not align data at least to size of pointer, they uses a
smaller alignment, but our pointer should be aligned to its native
boundary, otherwise on some platforms, hardware alignment checking
will cause bus error.

attempt a ZFS boot if there is more than one ZFS
dataset found during the disk probe.

- Add the ZFS pool and filesystem tables
devicename.c
- correctly format ZFS devices

- increase the size of the libstand malloc pool
to account for the increased usage from ZFS buffers
- probe for a ZFS dataset, and if one is
found, attempt to boot from it.
