0c2778236c Don't create the percpu clock interrupt threads as softint threads 
because they aren't softint threads.  This fixes callouts in
situations where there is nothing else happening in the rump kernel
(i.e. no threads executed which would trigger the softints when
they unschedule).

f762b5222f Use correct indices for clock threads and more descriptive ones 
for the softint threads.

a481b222d2 Remove questionable KASSERT from previous. hannken can look at 
this more closely when he wakes up.  Normally I wouldn't be in such
a huge rush, but due to atf bug #53 the whole test run breaks now.
At least with the KASSERT removed all tests pass again.

c84e81cad1 Add vm page flag PG_MARKER and use it to tag dummy marker pages 
in genfs_do_putpages() and uao_put().
Use 'v_uobj.uo_npages' to check for an empty memq.
Put some assertions where these marker pages may not appear.

Ok: YAMAMOTO Takashi <yamt@netbsd.org>

dadac8f503 Add select to list on compat syscalls. Makes some code work for 
me with a nb5 userland without having to compile with -g ;)

8b9126ba6d If a thread wake up spuriously, re-set l_mutex to make sure it's 
still at the original value and not the schedstate one.  This makes
select not miss wakeups in cases where there was a lot of selecting
going on (which is not all that common in a rump kernel).

f3c8997bfe Reset l_mutex when waking up a thread. select uses it to determine 
if a thread is still selecting, and would get a KASSERT panic if
the thread had been woken up but not run yet when selnotify() was
called.

0882d1cc0e Emulate malloc(9) a little better by panicking if a should-not-fail 
allocation fails.  We could invoke the pagedaemon here, but since
malloc(9) is panicky when it runs out of kmem_map, let's do the
"same".

9cb9168c28 Calculate memory mapping size based on underlying file size, not 
our window to it.  This fixes cases like opening a window at offsets
[8,32] to a file, which would cause host file offset [0,32-8] to
be mapped, i.e. [0,16] inside the window.  Obviously, access to
the entire in-window [0,24] range should have been mapped (and
after this fix it is).

cd3e4f8ebc Reinstate the blanket pmap.h for archs which do not conform to the 
kernel ABI (i.e. not i386 or amd64).  Due to the "half function,
half macro, all noodles" nature of pmap.h, it's too entangling and
too brittle to keep up with an ifdeffy MI implementation.

771f2275a6 Make it possible to define an upper limit for memory consumed by 
the rump kernel by specifying RUMP_MEMLIMIT.  In case allocation
over that limit is attempted, essentially pool reclaim and uvm_wait()
is done.  The default is to allow to allocate as much as the host
will give.

XXX: uvm_km_alloc and malloc(9) do not currently conform.  the
former is easy, the latter requires kern_malloc.c (rump malloc is
currently directly relegated to host malloc).
