Move the ZERO_REGION_SIZE to a machine-dependent file, as on many

2011-05-13T19:35:01+00:00

architectures (i386, for example) the virtual memory space may be
constrained enough that 2MB is a large chunk.  Use 64K for arches
other than amd64 and ia64, with special handling for sparc64 due to
differing hardware.

Also commit the comment changes to kmem_init_zero_region() that I
missed due to not saving the file.  (Darn the unfamiliar development
environment).

Arch maintainers, please feel free to adjust ZERO_REGION_SIZE as you
see fit.

- cosmetic changes and style fixes
- Trick GAS/GCC into compiling access to TICK/(S)TICK_COMPARE independently
  of the selected instruction set. Moreover, sun4v doesn't need the WAR for
  BlackBird CPUs.
- Rename the "xor" parameter to "xorval" as the former is a reserved keyword
  in C++.

Compile sys/dev/mem/memutil.c for all supported platforms and remove now
unnecessary dev_mem_md_init().  Consistently define mem_range_softc from
mem.c for all platforms.  Add missing #include guards for machine/memdev.h
and sys/memrange.h.  Clean up some nearby style(9) nits.
