PCI: Fix use of uninitialized MPS value

If "pcie_bus_config == PCIE_BUS_PERFORMANCE", we don't initialize "smpss",
so we pass a pointer to garbage into pcie_bus_configure_set(), where we
compute "mps" based on the garbage. We then pass the garbage "mps" to
pcie_write_mps(), which ignores it in the PCIE_BUS_PERFORMANCE case.

Coverity isn't smart enough to deduce that we ignore the garbage (it's a
lot to expect from a human, too), so initialize "smpss" to a safe value in
all cases.

Found by Coverity (CID 146454).

PCI: Remove dead code

"pdev" can never be NULL here, so remove the test.

MAINTAINERS: Add arch/x86/kernel/quirks.c to PCI file patterns

I'm not asserting any claim over arch/x86/kernel/quirks.c, and I don't plan
to merge changes to it, but some of the quirks there are PCI-related, and
I'd like to see changes to them.

PCI: Remove unnecessary __ref annotations

Some PCI functions used to be marked __devinit.  When CONFIG_HOTPLUG was
not set, these functions were discarded after boot.  A few callers of these
__devinit functions were marked __ref to indicate that they could safely
call the __devinit functions even though the callers were not __devinit.

But CONFIG_HOTPLUG and __devinit are now gone, and the need for the __ref
annotations is also gone, so remove them.  Relevant historical commits:

PCI: Fail new_id for vendor/device values already built into driver

While using the sysfs new_id interface, the user can unintentionally feed
incorrect values if the driver static table has a matching entry.  This is
possible since only the device and vendor fields are mandatory and the rest
are optional.  As a result, store_new_id() will fill in default values that
are then passed on to the driver and can have unintended consequences.

As an example, consider the ixgbe driver and the 82599EB network card:

  echo "8086 10fb" > /sys/bus/pci/drivers/ixgbe/new_id

This will pass a pci_device_id with driver_data = 0 to ixgbe_probe(), which
uses that zero to index a table of card operations.  The zeroth entry of
the table does *not* correspond to the 82599 operations.

This change returns an error if the user attempts to add a dynid for a
vendor/device combination for which a static entry already exists.
However, if the user intentionally wants a different set of values, she
must provide all the 7 fields and that will be accepted.

watchdog: via_wdt: replace del_timer by del_timer_sync

Use del_timer_sync to ensure that the timer is stopped on all CPUs before
the driver exits.

This change was suggested by Thomas Gleixner.

watchdog: Fix SBC8360 dependencies

According to its Kconfig help text, the sbc8360 watchdog driver is
only used on the Axiomtek SBC8360 single-board computer. This piece of
hardware is 32-bit x86 so the driver is useless beyond X86_32.
