Matthew D Fleming cfb00e5aa7 Move the ZERO_REGION_SIZE to a machine-dependent file, as on many ... 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. Requested by: alc MFC after: 1 week MFC with: r221853		2011-05-13 19:35:01 +00:00
