9b047d4a9a Enhance config to handle MACHINEs with multiple architectures:
- Passing -m to config will now print the MACHINE and MACHINE_ARCH
  given in the passed kernel configuration file and then exit.
- If an option is defined in options.MACHINE with the same name as the
  architecture of the kernel being configured, that option will be
  considered set. This allows conditional compilation based on CPU
  architecture.

Config version is now 600010.

72ccfc240b A previous change moved the GETATTR RPC for open() calls that hit in the
name cache up into nfs_lookup() instead of nfs_open().  Continue this
trend by flushing the attribute cache for leaf nodes in nfs_lookup() during
an open() if we do a LOOKUP RPC.  For NFSv3 this should generally be a NOP
as the attributes are flushed before fetching the post-op attributes from
the LOOKUP RPC which most (all?) NFSv3 servers provide, so the post-op
attributes should populate the cache.

Now all NFS open() calls will always clear the cached attributes during the
nfs_lookup() prior to nfs_open() in the !NMODIFIED case to provide CTOC.
As a result, we can remove the conditional flushing of the attribute
cache from nfs_open().

cd646aba81 Revert and remake r209883:
Do not grab lock while setting up interrupt, as it causes LOR with
allocation code. Instead make interrupt handler check that CAM bus
initialization completed before touching it.

While there, slightly improve attach errors handling.

160f3477ee Merge jmallett@'s n64 work into HEAD.
Merge changes for initial n64 support in pmap.c. Use direct mapped (XKPHYS)
access for a lot of operations that earlier needed temporary mapping. Add
support for using XKSEG for kernel mappings.

d1d3233ebd Convert Freescale PowerPC platforms to FDT convention.
The following systems are affected:

  - MPC8555CDS
  - MPC8572DS

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Freescale MPC85XX SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
    QUICC, UART, CFI.

  - Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
    ocpbus(4) driver, which was based on hard-coded config data.

Note that world for these platforms has to be built WITH_FDT.

3bc5958c0e Remove interval validation from cpu_tick_calibrate(). As I found, check
was needed at preliminary version of the patch, where number of CPU ticks
was divided strictly on 16 seconds. Final code instead uses real interval
duration, so precise interval should not be important. Same time aliasing
issues around second boundary causes false positives, periodically logging
useless "t_delta ... too long/short" messages when HZ set below 256.
