36 2) That setup code allocates (virtual) space for the "bounds directory",
54 bounds table (in the user address space) and makes the relevant entry
60 pointers, and we attempt to free the associated space in the bounds
71 * allocates virtual space for the bounds directory (malloc() essentially)
80 notices in the #BR exception, allocates the virtual space, then
113 by carving the space out of the normal processes address space and then
127 Q: Can virtual space simply be reserved for the bounds tables so that we
130 process address space to save bounds information. These tables can take
135 area needs 4*X GB of virtual space, plus 2GB for the bounds directory.
137 space, we would need to reserve 512TB+2GB, which is larger than the
138 entire virtual address space today. This means they can not be reserved
143 Q: Can we preallocate bounds table space at the same time memory is
