f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file 
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

0cde36f780 Carve off the ISA configuration bits from the floppy driver. Driver is 
still ISA-specific, but we can attach ISA instances with different
configuration mechanisms now.

b667a5a357 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

1bad2e1909 Add the RAIDframe device major to the machine-dependent config files

(Whoops!  I missed checking these in when adding the RAID_AUTOCONFIG stuff.)

fe551f0e64 Fix a bug in disksort_*() which caused non-optimal ordering when multiple

struct buf which contains the non-partition-relative block number to sort
by.

e9a0023b37 bring in content of GENERIC.v6 into GENERIC. 
remove GENERIC.v6 file (as it is part of GENERIC now).

"faith" interface is commented out by default as it is not really for
general use.
IPsec items are commented out as well, though we can enable "options IPSEC"
without export-related issue ("options IPSEC" will enable authentication
portion only).  We may need to think about it again.

if you have problem compiling with INET6 on archs I do not have access to,
please contact me.

XXX what to do with arch/arm32/SHARK{,.v6}?

eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions, 
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.
