* i386/i386/pcb.c (switch_ktss): Cleanly convert the value.

Import the macro definitions from the x15 kernel project, and replace
all similar definitions littered all over the place with it.
Importing this file will make importing code from the x15 kernel
easier. We are already using the red-black tree implementation and
the slab allocator from it, and we will import even more code in the
near future.

copy_from_phys): Avoid compiler warning about `map' being used
uninitialized.

xen cli/sti doesn't use IF

Previously, `copyinmsg' was the same function as `copyin'. The former
is for messages, and the size of messages is a multiple of four.
Likewise for `copyoutmsg'.
Provide a specialized version of both functions. This shaves off a
couple of instructions and improves our IPC performance.
* i386/i386/locore.S (copyinmsg): New function.
(copyoutmsg): New function.
|
|
* i386/i386/locore.S (copyout): Do not needlessly copy length to %eax
first.

we are in kernel land.

(spl) [MACH_KDB || MACH_TTD]: When curr_ipl is 7, make sure that IF is cleared.

restore them instead of blindly using sti.

zero.

registers have been zeroed.

PCB, and clear it.

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.

PCI devices expose their memory etc. way beyond last_phys_addr. Userland

This is more in line with how the function db_user_to_kernel_address() is

In this way everything falls into place and there is one cast less.
