The security_secid_to_secctx() function returns memory that must be freed
by a call to security_release_secctx() which was not always happening.  This
patch fixes two of these problems (all that I could find in the kernel source

Marcin Slusarz reported a ne2k-pci "hung network interface" regression.

delayed disable relies on the ability to re-trigger the interrupt in the
case that a real interrupt happens after the software disable was set.
In this case we actually disable the interrupt on the hardware level
_after_ it occurred.

On enable_irq, we need to re-trigger the interrupt. On i386 this relies
on a hardware resend mechanism (send_IPI_self()).

Actually we only need the resend for edge type interrupts. Level type
interrupts come back once enable_irq() re-enables the interrupt line.

I assume that the interrupt in question is level triggered because it is
shared and above the legacy irqs 0-15:

	17:         12   IO-APIC-fasteoi   eth1, eth0

Looking into the IO_APIC code, the resend via send_IPI_self() happens
unconditionally. So the resend is done for level and edge interrupts.
This makes the problem more mysterious.

The code in question lib8390.c does

	disable_irq();
	fiddle_with_the_network_card_hardware()
	enable_irq();

The fiddle_with_the_network_card_hardware() might cause interrupts,
which are cleared in the same code path again,

Marcin found that when he disables the irq line on the hardware level
(removing the delayed disable) the card is kept alive.

So the difference is that we can get a resend on enable_irq, when an
interrupt happens during the time, where we are in the disabled region.

Make sure to reduce the rating of the ITC clock if ITCs are drifty. If they
are drifting then we have not synchronized the ITC values, nor are we doing
the jitter compensation (useless since drift may increase the differentials
arbitrarily).

Without this patch it is possible that the ITC clock becomes selected as
the system clock on systems with drifty ITCs which will result in
nanosleep hanging.

One can still select the itc clock manually on such systems via

clocksource=itc

(Produces nice hangs on SGI Altix.)

If the sn2_rtc clock is present then it is a must have since sn2_rtc
provides a synchronized time source on Altix systems. So elevate
the priority to 450. Otherwise the ITC would take precendence. Altix
systems currently do not boot because the ITC clocksource is broken. It
seems to assume that ITCs are synchronized and as a result nanosleep
hangs (may be fixed in a different patch).

While we are at it: Remove the sn2_mc definition. The sn2_rtc has a fixed
address. No point in reading the address from memory. Removing it avoids
touching one cacheline.

Alexey Dobriyan noticed that the new WARN_ON() semantics that were
introduced by commit 684f9783 (to also
return the value to be warned on) didn't compile when given a bitfield,
because the typeof doesn't work for bitfields.

So instead of the typeof trick, use an "int" variable together with a
"!!(x)" expression, as suggested by Al Viro.

To make matters more interesting, Paul Mackerras points out that that is
sub-optimal on Power, but the old asm-coded comparison seems to be buggy
anyway on 32-bit Power if the conditional was 64-bit, so I think there
are more problems there.

Regardless, the new WARN_ON() semantics may have been a bad idea.  But
this at least avoids the more serious complications.
