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. kern: use a general lock for the IPC structures 2015-07-26T10:14:18Z Justus Winter 4winter@informatik.uni-hamburg.de 2015-07-25T00:29:58Z urn:sha1:75e6b9de564382ce5e4d4f2092635ccded70a14c * ipc/ipc_thread.h (ith_{lock_init,lock,unlock}): Use a general lock. * kern/task.h (struct task): Use a general lock for `itk_lock_data'.
