Chris found that with data journaling a reiserfs pagecache may be truncate
while still pinned.  The truncation removes the page->mapping, but the page
is still listed in the VM queues because it still has buffers.  Then during
the journaling process, a buffer is marked dirty and that sets the PG_dirty
bitflag as well (in mark_buffer_dirty).  After that the page is leaked
because it's both dirty and without a mapping.

So we must allow pages without mapping and dirty to reach the PagePrivate
check.  The page->mapping will be checked again right after the PagePrivate
check.

There is a bug booting with CONFIG_NUMA=y, CONFIG_X86_GENERICARCH=y, and
booting on a non-NUMA system.  While not the most common configuration, it
should surely be supported.

memmap_init_zone() is the first user to do pfn_to_nid(), which relies on
physnode_map[] to be done properly.  memory_present() was supposed to do
that, but never got called for the flat configuration, so pfn_to_nid() was
returning -1 on valid pages.

This patch further cleans up the appearance of TF in eflags when ptrace is
involved.  With this, PTRACE_SINGLESTEP will not cause TF to appear in
eflags as seen by PTRACE_GETREGS and the like, when the instruction faulted
for some reason other than the single-step trap.

This moves the check added by Dan's patch from setup_sigcontext to
handle_signal.  This is a cosmetic difference, but I think it makes more
sense to consolidate all the "reset registers to canonical state" work in
the same place (i.e. put it with the syscall rollback code), separate from
the signal handler setup.

The change that matters is moving the similar check out of do_debug,
where it only covers the case of a single-step trap.  Instead, it goes
into the ptrace_signal_deliver macro, which is called before the ptrace
stop for whatever signal results from whatever kind of fault in that
instruction (or asynchronous signal).  With that, the handle_signal
check is still needed only for the case of PTRACE_SINGLESTEP with a
handled signal.

Two problems occurred with the recent switch to virtual interrupt numbers.

The first is that two devices (eg Lasi PS/2 mouse and keyboard) can
share the same physical interrupt and should therefore share the same
virtual interrupt rather than have a new one assigned to them.  Fix this
by initialising the global_irq array to NO_IRQ, then checking the array
before assigning a new one.

The second is that some GSC devices (eg HIL and EISA) can have
two interrupts; one for normal interrupts and the other for NMI or
high-priority.  To fix this, I introduced an auxiliary IRQ to the
parisc_device and fill it in in Asp and Wax.
