+
+#.  In the initial implementation, it was the case that:
+#.      In fact the whole process is switched to use 4 kB hardware pages when the
+#.      subpage_prot system call is used, but this could be improved in future
+#.      to switch only the affected segments.
+#.  But Paul Mackerass says (Oct 2010): I'm pretty sure we now only switch
+#.  the affected segment, not the whole process.

+"This system call is provided to assist writing emulators that operate using "
+"64-kB pages on PowerPC systems.  When emulating systems such as x86, which "
+"uses a smaller page size, the emulator can no longer use the memory-"
+"management unit (MMU)  and normal system calls for controlling page "
+"protections.  (The emulator could emulate the MMU by checking and possibly "
+"remapping the address for each memory access in software, but that is "
+"slow.)  The idea is that the emulator supplies an array of protection masks "
+"to apply to a specified range of virtual addresses.  These masks are applied "
+"at the level where hardware page-table entries (PTEs)  are inserted into the "
+"hardware page table based on the Linux PTEs, so the Linux PTEs are not "
+"affected.  Implicit in this is that the regions of the address space that "
+"are protected are switched to use 4-kB hardware pages rather than 64-kB "
+"hardware pages (on machines with hardware 64-kB page support)."
