Oh, well. I should have used wait_event_interruptible_timeout when I
ported this driver to 2.6.

This patch fixes recently introduced race and also cleans ups some

This didn't show up in my "allmodconfig" tests, because the
console requires things to be built-in, not modules.

Posix timers preallocate siqueue structures during timer creation
and keep them for reuse.  This allocation happens in user context
with no locks held, however it's designated as an atomic allocation.
Loosen this restriction, and while we're at it let's do a bit of code
consolidation so signal sending uses same __sigqueue_alloc() helper.

When the generic IRQ stuff went in, it seems that HARDIRQ_BITS got bumped
from 9 (for ppc64) up to 12.  Consequently, the PREEMPT_ACTIVE bit is now
within HARDIRQ_MASK, and I get in_interrupt() falsely returning true when
PREEMPT_ACTIVE is set, and thus a BUG_ON tripping in arch/ppc64/mm/tlb.c.

The patch below fixes this by changing PREEMPT_ACTIVE to 0x10000000.  I
have changed the PREEMPT_ACTIVE definitions for each of the architectures
that define CONFIG_GENERIC_HARDIRQS (i386, ppc, ppc64, x86_64) and fixed
the comment in include/linux/hardirq.h.  We could perhaps move the
PREEMPT_ACTIVE definition to include/linux/hardirq.h - I don't know why it
is still per-arch.

The current "generic" implementation of IRQ probing isn't well suited
for ppc in it's current form, and causes issues with yenta_socket
(and possibly others) on pmac laptops. We didn't have a probe implementation
in the past, we probably don't need one anyway, so for now, the fix is to
make this optional and enable it on x86 and x86_64 but not ppc and ppc64
(the 4 archs to use the generic IRQ code).

This patch, from John Rose, is the counterpart of one recently
forwarded by Greg KH.  It has the same description, but isn't the same
patch - this is the arch/ppc64 part of the change.

As an unfortunate side effect of runtime addition/removal of PCI Host Bridges,
the RPA DLPAR driver can no longer depend on the success of ioremap_explicit()
(and therefore remap_page_range()) for the case of DLPAR adding an I/O Slot.  

Without addressing this, an attempt to add the first child slot of a newly
added PHB will fail when __ioremap_explicit() determines the mappings for that
range to already exist.

For a little context, __ioremap_explicit() creates mappings for the range of a
newly added slot.  Here's why these calls will be expected to fail in some
cases.  Keep in mind that at boot-time, the PPC64 kernel calls ioremap() for
the entire range spanned by each PHB.  Consider the following scenarios of
DLPAR-adding an I/O slot.

1) Just after boot, one removes an I/O slot.  At this point the range
   associated with the parent PHB is fragmented, and the child range for the
   slot in question is iounmap()'ed.  One then re-adds the slot, at which point
   remap_page_range()/ioremap_explicit() restores the mappings that were
   previously removed.

2) One adds a new PHB, at which point the ppc64-specific addition ioremaps the
   entire PHB range.  One then performs a DLPAR-add of a child slot of that
   PHB.  At this point, mappings already exist for the range of the slot to
   be added.  So remap_page_range()/ioremap_explicit() will fail at this point.

The problem is, there's not a good way to distinguish between cases 1 and 2
from the perspective of the DLPAR driver.  Because of that, I believe the
correct solution to be:

- Removal of relevant error prints from iounmap_explicit(), which is only used
  for DLPAR.
- Removal of error code checks from the RPA driver

Here's the first of these.
