* whose value is the bit's index is present in the associated zone's hosted
* Solaris 10 environment.
*
* NOTE: There must be at least one byte in the bitmap.
*
* because they operate on ulong_t arrays. The size of a ulong_t depends on
* the data model in which the code that declares the ulong_t is compiled:
* four bytes on 32-bit architectures and eight bytes 64-bit architectures.
* If the kernel is 64-bit and a 32-bit process executes in a solaris10-
* branded zone, then if the process' emulation library, which is 32-bit,
* queries the kernel for the zone's emulation bitmap, then the kernel will
* refuse because the library will request a bitmap that's half as big
* as the bitmap the kernel provides. The 32-bit emulation library would need
* its own macros to define and operate on bitmaps with 64-bit array elements.
* defining and using our own constants and macros for bitmap manipulations.
