Import AFLAGS to allow processing of assembler files in modules.
Prerequisite for kern/583346.

Introduce sys/modules/Makefile.compat and hook some compat_1[36]
machdep code into the modules.  kern/58346

Ooops missed a source file!

Proteect #include of kernel options files with #ifdef _KERNEL_OPT

XXX Add to existing 10.0 and 9.0 tickets for kern/583346

Include required headers

Add required include for compat_16 machdep code

fix the m68k compat_13 build.

include Makefile.assym to generate assym.h.
use -I. and -x assembler-with-cpp to actually use cpp and find assym.h.
also apply m68k assym.h fix here as well as compat_13.

powerpc64: Provide dummy stubs for compat1[36]
as done for amd64. We haven't had working userland for powerpc64,
and therefore compatible to 1.[36] is only useful for netbsd32.

Fix build failure for evbppc64 for PR kern/58346 (my bug!).
sun2/genassym.cf: Skip KERNBASE for _MODULE
as it is not a compile-time constant; see sun2/vmparam.h.

It should not be, and is not actually, used for modules.

PR kern/58346

sun2/enable.h: Fix -Wold-style-definition for WARNS=5 build as modules
Finally fix sun2 build for PR kern/58346

- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places.  Reduce sys/user.h inclusions.

Use lwp_getpcb() on mips, powerpc and sh3, clean from struct user usage.

Per discussion with ad at n dot o, revert signal mask handling
changes.

The l_sigstk changes are most likely totally un-needed as SA will
never use a signal stack - we send an upcall (or will as other
diffs are brought in).

The l_sigmask changes were too controvertial. In all honesty, I
think it's probably best to revert them. The main reason they were
there is the fact that in an SA process, we don't mask signals per
kernel thread, we mask them per user thread. In the kernel, we want
them all to get turned into upcalls. Thus the normal state of
l_sigmask in an SA process is for it to always be empty.

While we are in the process of delivering a signal, we want to
temporarily mask a signal (so we don't recursively exhaust our
upcall stacks). However signal delivery is rare (important, but
rare), and delivering back-to-back signals is even rarer. So rather
than cause every user of a signal mask to be prepared for this very
rare case, we will just add a second check later in the signal
delivery code. Said change is not in this diff.

This also un-compensates all of our compatability code for dealing
with SA. SA is a NetBSD-specific thing, so there's no need for
Irix, Linux, Solaris, SVR4 and so on to cope with it.

As previously, everything other than kern_sa.c compiles in i386
GENERIC as of this checkin. I will switch to ALL soon for compile
testing.

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.

Convert all the system call entry points from:
    int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).

Revamp how user MSR/SRR1 are dealt with.
Add a PSL_USEROK_P(psl) macro which valids the bits (replaces the use of
PSL_USERSTATIC).
Add a PSL_USERSRR1 mask which is used to mask out status bits in the upper
half of SRR1.
Make sure PSL_VEC is set appropriately in userret().  PSL_VEC is in the same
region as SSR1 status bits so it's not preserved on exceptions.  Thus we
need to make to set it.
When returning a MSR/SRR1 to userland, always clear the status bits.
Add emulation of the mfpvr, mtmsr, and mfmsr instructions.

Don't use trapframe in sigcontext.  Instead define a new structure
utrapframe that fixed in size (and the same size as the trapframe
in NetBSD 1.5).  This preserves binary compatibility for those programs
that dealt looked at sigcontexts.
