d15f935586 Oops. Last commit to tsb.h should have gone here.
Fix macros for eadling with tte contexts and add macros for sfsr fields.

491842fc97 Sigh. Add two files needed for the sparc64 fp contect switching code
that were forgotten in the last commit.

7cabcd9841 Move some code related to managing pv entries from the pmap module to
the pv module.  It works now that vtophys for sttes works.

d741ca6bdb Fix a bug translating virtual translation table entry addresses to physical
addresses.  It helps to use the physical address that the virtual address
actually maps to (doh!).  Comment out some code that crashes.

89bf8575ee Flesh out the sparc64 port considerably. This contains:
- mostly complete kernel pmap support, and tested but currently turned
  off userland pmap support
- low level assembly language trap, context switching and support code
- fully implemented atomic.h and supporting cpufunc.h
- some support for kernel debugging with ddb
- various header tweaks and filling out of machine dependent structures

98bb5304e1 Add skeleton machine dependent headers and c files for a port of freebsd
to a new architecture.  This is the base of the sparc64 port, but contains
limited machine dependent code, and can be used a base for ports.  Included
are:
- standard machine dependent headers, tweaked for a 64 bit, big endian
  architecture, including empty versions of all the machine dependent
  structures
- a machine independent atomic.h, which can be used until a port has
  support for interrupts and the operations really need to be atomic
- stub versions of all the machine dependent functions, which panic
  when called and print out the name of the function that needs to
  be implemented.  functions which are normally in assembly files are
  not included, but this should reduce the number of different undefined
  references on the first few compiles from hundreds to 5 or 6
Given minimal startup code and console support it should be trivial to
make this compile and run the first few sysinits on almost any architecture.

1f94b9005c Don't need the .keep_me files. Obrien and I committed past each other.
Add 0-9 to the list of possible kernel names at matsushita-san's
suggestion.

1453323996 Grrr, this was added in the wrong place.
Have I mentioned before how much I hate remove CVS when adding directories???
Ask me about it (got 3 hours...)
