- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
(might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
- Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
and the types __haiku_phys_[s]addr_t. The intention is to use separate
macros and types for virtual and physical addresses, since for some
architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
- Added types phys_[s]addr_t and respective printf() format macros.
- Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
B_HAIKU_PHYSICAL_{32,64}_BIT.
Might break the build under older Haiku installations. Will test next.
