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

178  * defining and using our own constants and macros for bitmap manipulations.
