In general, page size is not a function of the archetecture. This was addressed in the Go standard library here: https://go-review.googlesource.com/25051 This change simply defers to the standard library "syscall" package, which in turn defers to the runtime. This helps in addressing golang/go#10180 and also fixes a bug on ppc64. Currently, we return 65536 as the page size on ppc64, but the kernel supports 4k and 64k sizes, see here: http://elixir.free-electrons.com/linux/v4.13/source/arch/powerpc/include/asm/page.h#L24 Now that various page size calculations are not needed, various components are now dead code and can also be removed.
