NVMe: Always use MSI/MSI-x interrupts

BugLink: http://bugs.launchpad.net/bugs/1720867

Multiple users have reported device initialization failure due the driver
not receiving legacy PCI interrupts. This is not unique to any particular
controller, but has been observed on multiple platforms.

There have been no issues reported or observed when with message signaled
interrupts, so this patch attempts to use MSI-x during initialization,
falling back to MSI. If that fails, legacy would become the default.

The setup_io_queues error handling had to change as a result: the admin
queue's msix_entry used to be initialized to the legacy IRQ. The case
where nr_io_queues is 0 would fail request_irq when setting up the admin
queue's interrupt since re-enabling MSI-x fails with 0 vectors, leaving
the admin queue's msix_entry invalid. Instead, return success immediately.

neigh: ipv6: respect default values set before an address is assigned to device

commit bba24896f022d4d239494bebf18e713cd8aec7a5 upstream.

Make the behaviour similar to ipv4. This will allow user to set sysctl
default neigh param values and these values will be respected even by
devices registered before (that ones what do not have address set yet).

Revert "UBUNTU: SAUCE: disable stack-protector for ARM compressed bootloader"

This reverts commit 900be9e1bdc70f08ee67326254e1f340fba09541.

This SAUCE is no longer needed, since these commits fix the broken
stack-protector logic in arch/arm/Makefile:

stackprotector: Introduce CONFIG_CC_STACKPROTECTOR_STRONG
stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between architectures
