When generating stubs, Mig will will take the vm_size_array_t and define the
input request struct using rpc_vm_size_t since the size is variable. This will turn cause a mismatch
between types (vm_size_t* vs rpc_vm_size_t*). We could also ask Mig to produce
a prototype by using rpc_vm_size_t*, however we would need to change the implementation
of the RPC to use rpc_* types anyway since we want to avoid another allocation
of the array.

For coherency with memory_object_create_proxy.

To get a proxy to the region a given address belongs to,
with protection and range limited to the region ones.
* include/mach/mach4.defs: vm_region_get_proxy RPC declaration
* vm/vm_map.c: vm_region_get_proxy implementation

This is a no-op on i386.
* i386/include/mach/i386/vm_types.h (vm_size_array_t): New type.
* include/mach/mach4.defs (vm_size_array_t): New type.
(memory_object_create_proxy): Turn len parameter from vm_offset_array_t
to vm_size_array_t.
* vm/memory_object_proxy.c (memory_object_create_proxy): Turn len
parameter from const vm_offset_t * to const vm_size_t *.

This is required anyway, and allows the caller to pass on MAKE_SEND.

Memory object proxies permit to replicate objects with different parameters,
like reduced privileged, different offset, etc. They are e.g. essential for
properly managing memory access permissions.
2005-06-06 Marcus Brinkmann <marcus@gnu.org>
* include/mach/mach4.defs: Add memory_object_create_proxy
interface.
* Makefile.in (vm-cfiles): Add memory_object_proxy.c.

* include/mach/memory_object.h (memory_object_array_t): New type.
* vm/memory_object_proxy.c: New file.
* kern/ipc_kobject.h: New macro IKOT_PAGER_PROXY. Bump up macros
IKOT_UNKNOWN and IKOT_MAX_TYPE.
* kern/ipc_kobject.c (ipc_kobject_notify): Call
memory_object_proxy_notify for IKOT_PAGER_PROXY.
