2014-07-06i386: add io_map_cachedJustus Winter
io_map_cached is like io_map, but reuses the old mapping if it is applicable. * i386/i386/io_map.c: Add io_map_cached.
2014-06-11i386: remap some keysJustus Winter
As a convenience for the nice people using our debugger, remap some keys to the readline-like shortcuts supported by dde. * i386/i386at/kd.c (kdcnmaygetc): Remap some keys.
2014-06-11i386: reformat the key mapJustus Winter
* i386/i386at/kd.c (key_map): Remove superfluous newlines so that every entry fits into one line. This way line numbers can be used as an index into the map.

2014-04-30i386: fix MACHINE_SERVER_HEADERJustus Winter
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.
2014-04-30kern: include the MIG-generated server headers for MACHINE_SERVERJustus Winter
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.
