* anonymous.c (mdestroy) [! NDEBUG]: Don't void capability slots,
we destroy the associated objects, which does that.

the last reference.
(destroy): Assert that PAGER has no allocated storage.
|
|

mapping all of the requested if a single RPC is insufficient.

(hurd_mm_init): Don't initialize DEFAULT_CONTAINER. Don't
initialize the store data structures. Call memory_system_init,
core_system_init, hurd_anonymous_init, and map_system_init. Use
core_allocate rather than hurd_vm_allocate to allocate a stack for
the pager thread.
* pager.c (pager): Don't round ADDR. Call MAP->STORE->FAULT if
the physical memory is not cached.

documentation.

RPC identifier.
(hurd_pm_container_allocate): Use hurd_pm_container_allocate_id as
the RPC identifier.
(hurd_pm_container_deallocate): Use
hurd_pm_container_deallocate_id as the RPC identifier.
(hurd_pm_container_map): Use hurd_pm_container_map_id as the RPC
identifier. If AMOUNTP is non-NULL, return the number of bytes
mapped in *AMOUNTP. Remove debugging code.
(hurd_pm_container_copy): Use hurd_pm_container_copy_id as the RPC
identifier.
* anonymous.h: New file.
* anonymous.c: New file.
* as.c: New file.
* core.c: New file.
* frame.c: Remove file.
* store.c: New file.
