162 * whose value is the bit's index is present in the associated zone's hosted

167 * We don't use the bitmap macros provided by usr/src/uts/common/sys/bitmap.h

169 * the data model in which the code that declares the ulong_t is compiled:
170 * four bytes on 32-bit architectures and eight bytes 64-bit architectures.
171 * If the kernel is 64-bit and a 32-bit process executes in a solaris10-
172 * branded zone, then if the process' emulation library, which is 32-bit,
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.
177 * Thus using the sys/bitmap.h macros is probably more troublesome than
178 * defining and using our own constants and macros for bitmap manipulations.
