166 * four bytes on 32-bit architectures and eight bytes 64-bit architectures.

169 * queries the kernel for the zone's emulation bitmap, then the kernel will
170 * refuse because the library will request a bitmap that's half as big
171 * as the bitmap the kernel provides. The 32-bit emulation library would need
172 * its own macros to define and operate on bitmaps with 64-bit array elements.
