prints.

Since we need it to access some BIOS information, e.g. at ACPI shutdown. When
the kernel VM is not starting at 0, there is already nothing mapped there in
user tasks, anyway.
* i386/i386at/model_dep.c (machine_init) [VM_MIN_KERNEL_ADDRESS != 0]:
Do not call pmap_unmap_page_zero.
* i386/intel/pmap.c (pmap_unmap_page_zero): Warn that unmapping page
zero may break some BIOS functions.

io_map_cached is like io_map, but reuses the old mapping if it is
applicable.

Commit b6dab094 introduced a way to include the MIG-generated server
files for the machine specific interface in ipc_kobject.c.
This broke out-of-tree builds. Here, 'machine' is a symlink to
'../i386/i386', it points into the source tree. The MIG-generated
files however are put in the build tree in i386/i386.
* i386/i386/machine_routines.h (MACHINE_SERVER_HEADER): Fix path.
|
|
GNU MIG recently gained support for emitting x_server_routine
declarations in the generated server header file. Using this
declaration, the x_server_routine functions can be inlined into the
ipc_kobject_server function.
* kern/ipc_kobject.c: Include the MIG-generated server headers for the
machine-dependent interfaces.
(ipc_kobject_server): Drop the simple declaration of
MACHINE_SERVER_ROUTINE.
* i386/i386/machine_routines.h (MACHINE_SERVER_HEADER): New
definition.

CGA and MONO cards are more than hard to find nowadays, and some buggy BIOSes

initialization within PMAP_NMAPWINDOWS.
