2015-09-14kern/slab: directmap updateRichard Braun
The main impact of the direct physical mapping on the kmem module is the slab size computation. The page allocator requires the allocation size to be a power-of-two above the page size since it uses the buddy memory allocation algorithm. Custom slab allocation functions are no longer needed since the only user was the kentry area, which has been removed recently. The KMEM_CACHE_NOCPUPOOL flag is also no longer needed since CPU pools, which are allocated from a kmem cache, can now always be allocated out of the direct physical mapping.
2015-09-14device: use general lock for port listsJustus Winter

2015-09-14yyy more general locks, crashes, maybe b/c interrupt handlerJustus Winter
2015-07-11kern: make sure the queue macros are only used on queuesJustus Winter
This turns mistakes as the one corrected in e59f05e9 into compile-time errors. * kern/queue.h: Add a new macro, queue_assert, and use it to assert that all arguments given to the queue macros have the correct type. * device/net_io.c (ENQUEUE_DEAD): Adapt to the fact that `queue_next(q)' is no longer an lvalue.
2015-06-28i386: improve the immediate consoleJustus Winter

(immc_cnputc): Fix signature, use virtual addresses. * i386/i386at/immc.h: New file. * i386/i386at/kd.c: Use `#if ENABLE_IMMEDIATE_CONSOLE'. * i386/i386at/kd.h (kd_setpos): Add missing declaration. * i386/i386at/model_dep.c (c_boot_entry): Install immediate console as early boot console.
2015-05-19kern: import `macros.h' from x15Justus Winter
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.

2014-06-11device: fix net_rcv_msg-messagesJustus Winter
Previously, all net_rcv_msg-messages sent by net_deliver were malformed. It never was a problem in practice, since the messages are not complex and thus the kernel does not try to parse the message. struct net_rcv_msg contains an additional field of type boolean_t. This field has no associated type descriptor, so it must not be included in the message. * device/net_io.c (net_deliver): Account for the extra field in the msgh_size calculation.
