When the GIC is using EOImode==1, the EOI is done immediately,
leaving the deactivation to be performed when the EOI was
previously done.

Unfortunately, the ITS is not aware of the EOImode at all, and
blindly EOIs the interrupt again. On most systems, this is ignored
(despite being a programming error), but some others do raise a
SError exception as there is no priority drop to perform for this
interrupt.

The fix is to stop trying to be clever, and always call into the
underlying GIC to perform the right access, irrespective of the
more we're in.

The ARM GICv3 specification mentions the need for dsb after a read
from the ICC_IAR1_EL1 register:

	4.1.1 Physical CPU Interface:
	The effects of reading ICC_IAR0_EL1 and ICC_IAR1_EL1
	on the state of a returned INTID are not guaranteed
	to be visible until after the execution of a DSB.

Not having this could result in missed interrupts, so let's add the
required barrier.

EOImode1 is only used for the root controller and hence only the root
controller uses the eoimode1 functions for handling interrupts. However,
if the root controller supports EOImode1, then the EOImodeNS bit will be
set for all GICs, enabling EOImode1. This is not what we want and this
causes interrupts on non-root GICs to only be dropped in priority but
never deactivated. Therefore, only set the EOImodeNS bit for the root
controller.

The current ITS driver has a memory leak in its_free_tables(). It
happens on tear down path of the driver when its_probe() call fails.
its_free_tables() should free the exact number of pages that have
been allocated, not just a single page as current code does.

This patch records the memory size for each ITS_BASERn at the time of
page allocation and uses the same size information when freeing pages
to fix the issue.

The Allwinner sunxi specific interrupt controller cannot be compiled
for any architecture except arm:

drivers/irqchip/irq-sun4i.c:25:26: fatal error: asm/mach/irq.h: No such file or directory
compilation terminated.

It turns out that this header is actually not needed for the driver, so remove
it and allow compilation for other architectures like arm64.

  Other than that, a few trivial fixes and quirks for FireWire BeBoB,
  USB-audio and HD-audio are found, too"

Pull security layer fixes from James Morris:
 "The keys patch fixes a bug which is breaking kerberos, and the seccomp
  fix addresses a no_new_privs bypass"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
  KEYS: Only apply KEY_FLAG_KEEP to a key if a parent keyring has it set
  seccomp: always propagate NO_NEW_PRIVS on tsync

This reverts commit 14e46e04.

This ends up doing sysfs operations from deep in balance (where we
should be GFP_NOFS) and under heavy balance load, we're making races
against sysfs internals.

Revert it for now while we figure things out.
