Hans Petter Selasky 1ea4c85781 Implement proper support for memory map operations in the LinuxKPI, ... like open, close and fault using the character device pager. Some notes about the implementation: 1) Linux drivers set the vm_ops and vm_private_data fields during a mmap() call to indicate that the driver wants to use the LinuxKPI VM operations. Else these operations are not used. 2) The vm_private_data pointer is associated with a VM area structure and inserted into an internal LinuxKPI list. If the vm_private_data pointer already exists, the existing VM area structure is used instead of the allocated one which gets freed. 3) The LinuxKPI's vm_private_data pointer is used as the callback handle for the FreeBSD VM object. The VM subsystem in FreeBSD has a similar list to identify equal handles and will only call the character device pager's close function once. 4) All LinuxKPI VM operations are serialized through the mmap_sem sempaphore, which is per procedure, which prevents simultaneous access to the shared VM area structure when receiving page faults.
