Restoring the instruction pointer within the critical section is
problematic because rseq_cs may get cleared before the control is
passed to the migrated application code leading to RSEQ invariants not

pci_alloc_irq_vectors() will handle fallback from MSI-X to MSI
internally, if necessary. So remove checks which determine if we are
dealing with MSI or MSI-X and rely on pci_alloc_irq_vectors() to do the

There are several places in the kernel which check/ask for MSI or MSI-X
interrupts. It would make sense to have a macro which defines all types
of message signalled interrupts, to use in such situations. Add
PCI_IRQ_MSI_TYPES, for this purpose.

Changes for v7:
- replace readls with ioread32_rep and writesl with iowrite32_rep
to avoid compilation errors on parisc architecture
Changes for v6:
- add support for bank addressing
elected sector size. Therefore there is a separate
function for calculating ECC size for each of possible
sector size/step size.
