sceKernelMunlock and the POSIX munlock unlock the page-rounded range with
FreeBSD's results: 0 for a mapped range whether or not it is locked, EINVAL
for a range that wraps around zero, ENOMEM for an unmapped range. On Linux
the host munlock gives them. On Windows a reserved placeholder counts as
mapped only while the guest reservation or protection registry covers it,
and a region VirtualUnlock refuses as not fully locked is unlocked page by
page, as VirtualUnlock is all-or-nothing. sceKernelMlock shares the range
rounding.

The POSIX form of sceKernelMlock: 0 on success, -1 with errno (EINVAL,
ENOMEM, EPERM, EAGAIN) where the sce form returns the kernel error, as
munmap and mprotect do beside it.
