* kern/sched_prim.c (sched_init): Remove cast of recompute_priorities.
Replace (char *)0 with NULL.
(thread_timeout): Set parameter type to void * instead of thread_t, and
implicitly cast the former into the latter instead.
(thread_timeout_setup): Remove cast of thread_timeout, cast
thread_depress_timeout into (void (*) (void*)). Remove cast of thread.
(thread_recompute_priorities): Add unused void * parameter.

* i386/i386at/model_dep.c (init_alloc_aligned): Add declaration.
(i386at_init): Use init_alloc_aligned to allocate memory to save the
content pointed by boot_info: cmdline, mods_addr, mod_start, and string.
Set kernel_cmdline to the newly allocated string.
(c_boot_entry): Do not set kernel_cmdline.
|
|
* i386/i386at/model_dep.c (mem_size_init): Move avail_remaining computation to
after all phys_last_addr corrections.

kern/zalloc.c (zone_map_size): Increase to 64MiB.
i386/i386at/model_dep.c (mem_size_init): Reduce cap to 1/6 of memory
space to save room for zalloc area.
linux/src/drivers/block/ide.h (INITIAL_MULT_COUNT): Set to 16.
vm/vm_map.h (VM_MAP_COPY_PAGE_LIST_MAX): Set to 64.
vm/vm_object.c (vm_object_cached_max): Set to 4000.

|
i386/i386at/model_dep.c (mem_size_init): Advertise memory size
truncations.

It messes too much with probing and brings hang issue.
* i386/linux/dev/include/linux/autoconf.h
(CONFIG_BLK_DEV_CMD640, CONFIG_BLK_DEV_CMD640_ENHANCED):
Undefine macros.
|
|

(invlpg_linear_range): ... this.
(invlpg_linear): New macro.
* i386/intel/pmap.c (INVALIDATE_TLB): Call invlpg_linear instead
of flush_tlb when e - S is compile-time known to be PAGE_SIZE,
instead of run-time known to be less than 32 * PAGE_SIZE.
