Subject: [11/89] arch/tile: allocate PCI IRQs later in boot

2.6.39-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Chris Metcalf <cmetcalf@...era.com>

commit f4de51de2edcd26ec77bfc71b1f00b1de5a5dc20 upstream.

This change became required due to some recent reworking in the
platform-independent IRQ code.  It is required for 2.6.38 and later.
