bpf(4) are different enough so that the split makes sense -- this is necessary
to make bpf(4) cloneable.

This will allow the softfloat code to be used by other platforms than alpha.

rpc/pmap_prot.h collide.. "struct pmap" from the kernel should not make

remove pool_cache code. it was barely used, and quite complex. it's
silly to have both a "fast" and "faster" allocation interface. provide
a ctor/dtor interface, and convert the few cache users to use it. no
caching at this time.
use mutexes to protect pools. they should be initialized with pool_setipl
if the pool may be used in an interrupt context, without existing spl
protection.

directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.
There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.
Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

decide which files must be pulled into the kernel. Also conditionalize
the pulling of those files based on the COMPAT_* options.

- Move the functionality of choosing a process from cpu_switch into
a much simpler function: cpu_switchto. Instead of having the locore
code walk the run queues, let the MI code choose the process we
want to run and only implement the context switching itself in MD
code.
- Let MD context switching run without worrying about spls or locks.
- Instead of having the idle loop implemented with special contexts
in MD code, implement one idle proc for each cpu. make the idle
loop MI with MD hooks.
- Change the proc lists from the old style vax queues to TAILQs.
- Change the sleep queue from vax queues to TAILQs. This makes
wakeup() go from O(n^2) to O(n)
there will be some MD fallout, but it will be fixed shortly.
There's also a few cleanups to be done after this.

size(*p) as the first malloc() parameter where p is declared locally
and thus easy to check. Add M_ZERO to gpe_table allocation in acpi.c
even though there is no obvious bzero or memset nearby.
|
|
otherwise just adding M_ZERO to malloc() and removing the immediately
adjacent memset(,0,).

previously applied to other archs deleting a memset() this time. e.g.
- if ((mapstore = malloc(mapsize, M_DEVBUF,
- (flags & BUS_DMA_NOWAIT) ? M_NOWAIT : M_WAITOK)) == NULL)
+ if ((mapstore = malloc(mapsize, M_DEVBUF, (flags & BUS_DMA_NOWAIT) ?
+ (M_NOWAIT | M_ZERO) : (M_WAITOK | M_ZERO))) == NULL)
return (ENOMEM);
- memset(mapstore, 0, mapsize);
|
|
- if ((mapstore = malloc(mapsize, M_DEVBUF,
- (flags & BUS_DMA_NOWAIT) ? M_NOWAIT : M_WAITOK)) == NULL)
+ if ((mapstore = malloc(mapsize, M_DEVBUF, (flags & BUS_DMA_NOWAIT) ?
+ (M_NOWAIT | M_ZERO) : (M_WAITOK | M_ZERO))) == NULL)
return (ENOMEM);
- bzero(mapstore, mapsize);

the holes a MMU may have from a given vm_map. This will be automagically
invoked for newly created vmspaces.
On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents
mmap(2) hints which would end up being in the hole to be accepted as valid,
causing unexpected signals when the process tries to access the hole
(since pmap can not fill the hole anyway).
Unfortunately, the logic mmap() uses to pick a valid address for anonymous
mappings needs work, as it will only try to find an address higher than the
hint, which causes all mmap() with a hint in the hole to fail on vax. This
will be improved later.

more commonly encountered level 4. Do not complain in splassert() in this case
(this is similar to the older vsbus vax machines workaround).
