The lookup function tries to acquire the already held mutex. Avoid that by caching the Linux interrupt number at initialization time instead of looking it up over and over.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When kernel boots with a NUMA topology with some NUMA nodes offline, the PCI driver should only set an online NUMA node on the device. This can happen during KDUMP where some NUMA nodes are not made online by the KDUMP kernel. This patch also fixes the case where kernel is booting with "numa=off".

Joey bisected the issues to 0e8ae5a6ff59, so revert it until we figure out a better solution.

The original code just returned a NULL pointer in that case, but the rework added a WARN_ON() under the assumption that the corresponding WARN_ON() in the MSI case can be applied to MSI-X as well. In fact the MSI warning in the original code does not make sense either because it's legitimate to invoke pci_irq_get_affinity() for a MSI interrupt which was not allocated with affinity descriptor information. Remove it and just return NULL as the original code did.

We correctly stored an __iomem pointer in struct spear13xx_pcie, but discarded the __iomem when extracting app_base, causing one warning. Then we passed the non-__iomem pointer to writel(), which expects an __iomem pointer, causing another warning. Add the appropriate annotations.
