On sparc, the minimal page size we can use is 8K. Since B_PAGE_SIZE and PAGESIZE defines were hardcoded to 4K, this resulted in a lot of confusion in all code trying to manipulate pages. - Remove cpu.h from headers/private/kernel/arch/*. It dates back from NewOS and was not used anymore since our kernel uses B_PAGE_SIZE (PAGE_SIZE was the only thing defined in this header). - Add posix/arch/*/limits.h with the arch specific page size and include it from the main limits.h. - Adjust bios_ia32/debug.cpp which was the only place using the PAGE_SIZE constant from the deleted headers. - Change OS.h to define B_PAGE_SIZE to be the same as POSIX PAGESIZE. - Define PAGESIZE in the build header if the host OS doesn't.
