ENOTSUPP is not a valid error code in the kernel (it is defined in some
NFS internal error codes and has been improperly used other places).  In
the !CONFIG_SECURITY_SELINUX case though it is possible that we could
return this from selinux_audit_rule_init().  This patch just returns the
userspace valid EOPNOTSUPP.

This code harks back to the days when we didn't count dirty mapped
pages, which led us to try to balance the number of dirty unmapped pages
by how much unmapped memory there was in the system.

That makes no sense any more, since now the dirty counts include the
mapped pages.  Not to mention that the math doesn't work with HIGHMEM
machines anyway, and causes the unmapped_ratio to potentially turn
negative (which we do catch thanks to clamping it at a minimum value,
but I mention that as an indication of how broken the code is).

The code also was written at a time when the default dirty ratio was
much larger, and the unmapped_ratio logic effectively capped that large
dirty ratio a bit.  Again, we've since lowered the dirty ratio rather
aggressively, further lessening the point of that code.

This routine is called each time hash should be replaced, nf_conn has
extension list which contains pointers to connection tracking users
(like nat, which is right now the only such user), so when replace takes
place it should copy own extensions. Loop above checks for own
extension, but tries to move higer-layer one, which can lead to above
oops.

This matters to any sort of device that is wired to one of the CPU
interrupt pins on an SMP system.  Typically the scenario is most easily
triggered with the count/compare timer interrupt where the same interrupt
number and thus irq_desc is used on each processor.

   CPU A			CPU B

   do_IRQ()
   generic_handle_irq()
   handle_level_irq()
   spin_lock(desc_lock)
   set IRQ_INPROGRESS
   spin_unlock(desc_lock)
				do_IRQ()
				generic_handle_irq()
				handle_level_irq()
				spin_lock(desc_lock)
				IRQ_INPROGRESS set => bail out
   spin_lock(desc_lock)
   clear IRQ_INPROGRESS
   spin_unlock(desc_lock)

In case of the cp0 compare interrupt this means the interrupt will be
acked and not handled or re-armed on CPU b, so there won't be any timer
interrupt until the count register wraps around.

With kernels 2.6.20 ... 2.6.23 we usually were lucky that things were just
working right on VSMP because the count registers are synchronized on
bootup so it takes something that disables interrupts for a long time on
one processor to trigger this one.

For scenarios where an interrupt is multicasted or broadcasted over several
CPUs the existing code was safe and the fix will break it.  There is no
way to know in the interrupt controller code because it is abstracted from
the platform code.  I think we do not have such a setup currently, so this
should be ok.

We have no guarantee by the generic time code that the timer is stopped
when the ->next_event method is called.  Modifying the Timer Initial Count
register while the timer is enabled has UNPREDICTABLE effect according to
the BCM1250/BCM1125/BCM1125H User Manual.  So stop the timer before
reprogramming.

This is a paranoia fix; no ill effects have been observed previously.

For the old minimum of a single tick a value of zero would be programmed
into the init value register which in the BCM1250/BCM1125/BCM1125H User
Manual in the Timer Special Cases section is documented to have
UNPREDICTABLE effect.

Observable sympthoms of this bug were hangs of several seconds on the
console during bootup and later if both dyntick and highres timer options
were activated.

In theory contiguous mode of the timers is also affected but in an act of
hopeless lack of realism I'll assume nobody will ever configure a KERNEL
for HZ > 500kHz but if so I leave that to evolution to sort out.

Shadow register support would not possibly have worked on multicore
systems.  The support code for it was also depending not on MIPS R2 but
VSMP or SMTC kernels even though it makes perfect sense with UP kernels.

SR sets are a scarce resource and the expected usage pattern is that
users actually hardcode the register set numbers in their code.  So fix
the allocator by ditching it.  Move the remaining CPU probe bits into
the generic CPU probe.

This avoids us executing an mfc0 c0_count instruction on processors which
don't have but also on certain R4000 and R4400 versions where reading from
the count register just in the very moment when its value equals
c0_compare will result in the timer interrupt getting lost.

There is still a number of users of get_cycles remaining outside the
arch code:

crypto/tcrypt.c:                start = get_cycles();

cpu_down() code is ok wrt sched_idle_next() placing the 'idle' task not

So get rid of activate_idle_task() and make use of activate_task() instead.
It is the same as activate_task(), except for the update_rq_clock(rq) call
that is redundant.
