3bbb7f7d45 Move pmap_map() function definition to MD headers, as appropriate. It's 
an internal function, and the VM system shouldn't try to prototype it.
(Note that some ports _don't_ prototype it.)

4399060ec9 - Perform all necessary bus_dmamap_sync() operations.

  for group changes.
* Since the above is a violation of the semantics specified by POSIX and
  X/Open, add corresponding compatibility syscalls: __posix_chown(),
  __posix_fchown(), __posix_lchown().  (Neither fchown() nor lchown() is
  specified by POSIX; the prefix is intended to reflect the semantics.)

f49dd3ef30 Avoid declaring the "astpending" and "want_resched" globals in cpu.h,

872181c2f2 A few changes to make it possible to read UVM histories from userland: 
- Protect option headers from inclusion if ! _KERNEL or if _LKM.
- Make sure struct uvm_history is always the same size (not dependent
  on NCPU).
- Add fmtlen and fnlen members to struct uvm_history_ent, which specify
  the lengths fo the fmt and fn strings.
- Add name, namelen, and a list entry to struct uvm_history.
- When a history is initialized, place it on the global list of all histories.

25d056473c Clean up kernel initialization. Use the bootinfo structure (or innate 
knowledge) earlier, and gather all information needed earlier.  Mark the
init code carefully re: when it can print stuff out, when it can expect
the firmware to stop working, etc.  Be more careful about using the PROM
console and other PROM facilities, and hint that in the future all use
of firmware/boot program callbacks by the kernel should go away (since
the world may not be mapped the way the firmware/boot program wants!).

- In the console getc routine, block until a character becomes ready

- In the console putc routine, if the UART has trouble, do NOT proceed
  to print a diagnostic message, which would recursively invoke the
