otg_ulpi_create is defined in drivers/usb/otg/ulpi.c which depends on
CONFIG_USB_ULPI.  So protect its usage by the same symbol.  Moreover
mxc_ulpi_access_ops needs CONFIG_MXC_ULPI.

Commit 52939c03 (ARM: MX3: fix CPU revision number detection) started
using the CPU's SREV register for revision number detection. This
makes it mandatory to have a valid SPBA0 mapping. Add this to the
global map_io code instead of adding multiple copies for each board.

Commit 239007b8 ("genirq: Convert irq_desc.lock to raw_spinlock")
seems to have missed this driver, leaving it to use the normal spin-lock
functions for the irq descriptor lock, which is now a raw lock.

Introduced by commit 5b889bf2 ("PCI: Fix build if quirks are not
enabled"), which made the pci_dev_reset_methods[] array static and
'const', but didn't then change the code to match, and use a const
pointer when moving it to quirks.c.

Trivially fixed by just adding the required 'const' to the iterator
variable.

Comments from Stefan:

   Distributors who still ship the old stack (ieee1394, ohci1394,
   raw1394, sbp2, eth1394 and more) should now switch to the new one
   (firewire-core, firewire-ohci, firewire-sbp2, firewire-net).  In the
   first iteration, those distributors might want to ship the old stack
   also (but blacklisted) as a fallback for their users if unforeseen
   problems with the newer replacement drivers are encountered.

   The older FireWire stack contains several known problems which are
   not going to be fixed; instead, those issues are addressed by the new
   stack.  An incomplete list of these issues is kept in bugzilla:

	http://bugzilla.kernel.org/show_bug.cgi?id=10046

   We have a guide on migration from the older to the newer stack:

	http://ieee1394.wiki.kernel.org/index.php/Juju_Migration

After commit b9c3b266 ("PCI: support
device-specific reset methods") the kernel build is broken if
CONFIG_PCI_QUIRKS is unset.

Fix this by moving pci_dev_specific_reset() to drivers/pci/quirks.c and
providing an empty replacement for !CONFIG_PCI_QUIRKS builds.

Liming found a NULL deref when a task has a perf context but no
counters  when it forks.

This can occur in two cases, a race during construction where
the fork hits after installing the context but before the first
counter gets inserted, or more reproducably, a fork after the
last counter is closed (which leaves the context around).

Pass the frame pointer from the regs of the interrupted path
to dump_trace() while processing the stack trace.

Currently, dump_trace() takes the current bp and starts the
callchain from dump_trace() itself. This is wasteful because
we need to walk through the entire NMI/DEBUG stack before
retrieving the interrupted point.

We can fix that by just using the frame pointer from the
captured regs. It points exactly where we want to start.
