2016-02-02Stack the slab allocator directly on top of the physical allocatorRichard Braun
In order to increase the amount of memory available for kernel objects, without reducing the amount of memory available for user processes, a new allocation strategy is introduced in this change. Instead of allocating kernel objects out of kernel virtual memory, the slab allocator directly uses the direct mapping of physical memory as its backend. This largely increases the kernel heap, and removes the need for address translation updates. In order to allow this strategy, an assumption made by the interrupt code had to be removed. In addition, kernel stacks are now also allocated directly from the physical allocator. * i386/i386/db_trace.c: Include i386at/model_dep.h (db_i386_reg_value): Update stack check. * i386/i386/locore.S (trap_from_kernel, all_intrs, int_from_intstack): Update interrupt handling. * i386/i386at/model_dep.c: Include kern/macros.h.

2016-01-23Use vm_page as the physical memory allocatorRichard Braun
This change replaces the historical page allocator with a buddy allocator implemented in vm/vm_page.c. This allocator allows easy contiguous allocations and also manages memory inside segments.

2015-02-20i386: specialize `copyinmsg' and `copyoutmsg'Justus Winter
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'.
