2016-01-23	Use vm_page as the physical memory allocator	Richard 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. In a future change, these segments will be used to service requests with special constraints, such as "usable for 16-bits DMA" or "must be part of the direct physical mapping". * Makefrag.am (libkernel_a_SOURCES): Add vm/vm_page.c. * i386/Makefrag.am (libkernel_a_SOURCES): Add i386/i386at/biosmem.{c,h}. * i386/i386/vm_param.h: Include kern/macros.h. (VM_PAGE_DMA_LIMIT, VM_PAGE_MAX_SEGS, VM_PAGE_DMA32_LIMIT, VM_PAGE_DIRECTMAP_LIMIT, VM_PAGE_HIGHMEM_LIMIT, VM_PAGE_SEG_DMA, VM_PAGE_SEG_DMA32, VM_PAGE_SEG_DIRECTMAP, VM_PAGE_SEG_HIGHMEM): New macros. * i386/i386at/model_dep.c: Include i386at/biosmem.h. (avail_next, avail_remaining): Remove variables. (mem_size_init): Remove function. (i386at_init): Initialize and use the biosmem module for early physical memory management. (pmap_free_pages): Return phys_last_addr instead of avail_remaining. (init_alloc_aligned): Turn into a wrapper for biosmem_bootalloc. (pmap_grab_page): Directly call init_alloc_aligned instead of pmap_next_page. * i386/include/mach/i386/vm_types.h (phys_addr_t): New type. * kern/bootstrap.c (free_bootstrap_pages): New function. (bootstrap_create): Call free_bootstrap_pages instead of vm_page_create. * kern/cpu_number.h (CPU_L1_SIZE): New macro. * kern/slab.h: Include kern/cpu_number.h. (CPU_L1_SIZE): Remove macro, moved to kern/cpu_number.h. * kern/startup.c (setup_main): Change the value of machine_info.memory_size. * linux/dev/glue/glue.h (alloc_contig_mem, free_contig_mem): Update prototypes. * linux/dev/glue/kmem.c (linux_kmem_init): Don't use defunct page queue. * linux/dev/init/main.c (linux_init): Don't free unused memory. (alloc_contig_mem, free_contig_mem): Turn into wrappers for the vm_page allocator. * linux/pcmcia-cs/glue/ds.c (PAGE_SHIFT): Don't undefine. * vm/pmap.h (pmap_startup, pmap_next_page): Remove prototypes. * vm/vm_fault.c (vm_fault_page): Update calls to vm_page_convert. * vm/vm_init.c (vm_mem_init): Call vm_page_info_all. * vm/vm_object.c (vm_object_page_map): Update call to vm_page_init. * vm/vm_page.h (vm_page_queue_free): Remove variable declaration. (vm_page_create, vm_page_release_fictitious, vm_page_release): Remove declarations. (vm_page_convert, vm_page_init): Update prototypes. (vm_page_grab_contig, vm_page_free_contig): New prototypes. * vm/vm_resident.c (vm_page_template, vm_page_queue_free, vm_page_big_pagenum): Remove variables. (vm_page_bootstrap): Update and call vm_page_setup. (pmap_steal_memory): Update and call vm_page_bootalloc. (pmap_startup, vm_page_create, vm_page_grab_contiguous_pages): Remove functions. (vm_page_init_template, vm_page_grab_contig, vm_page_free_contig): New functions. (vm_page_init): Update and call vm_page_init_template. (vm_page_release_fictitious): Make static. (vm_page_more_fictitious): Update call to vm_page_init. (vm_page_convert): Rewrite to comply with vm_page. (vm_page_grab): Update and call vm_page_alloc_pa. (vm_page_release): Update and call vm_page_free_pa.
