With the introduction of stacked domains, we have the issue that, depending on where in the stack this is called, __irq_set_handler will succeed or fail: If this is called from the inner irqchip, __irq_set_handler() will fail, as it will look at the outer domain as the (desc->irq_data.chip == &no_irq_chip) test fails (we haven't set the top level yet). This patch implements the following: "If there is at least one valid irqchip in the domain, it will probably sort itself out". This is clearly not ideal, but it is far less confusing then crashing because the top-level domain is not up yet.

We plan to use hierarchy irqdomain to suppport CPU vector assignment, interrupt remapping controller, IO-APIC controller, MSI interrupt and hypertransport interrupt etc on x86 platforms. So extend irqdomain interfaces to support hierarchy irqdomain. There are already many clients of current irqdomain interfaces. To minimize the changes, we choose to introduce new version 2 interfaces to support hierarchy instead of extending existing irqdomain interfaces. According to Thomas's suggestion, the most important design decision is to build hierarchy struct irq_data to support hierarchy irqdomain, so hierarchy irqdomain related data could be saved in struct irq_data. With support of hierarchy irq_data, we could also support stacked irq_chips. This is most useful in case of set_affinity(). The new hierarchy irqdomain introduces following interfaces: 1) irq_domain_alloc_irqs()/irq_domain_free_irqs(): allocate/release IRQ and related resources. 2) __irq_domain_alloc_irqs(): a special version to support legacy IRQs. 3) irq_domain_activate_irq()/irq_domain_deactivate_irq(): program interrupt controllers to activate/deactivate interrupt. There are also several help functions to ease irqdomain implemenations: 1) irq_domain_get_irq_data(): get irq_data associated with a specific irqdomain. 2) irq_domain_set_hwirq_and_chip(): save irqdomain specific data into irq_data. 3) irq_domain_alloc_irqs_parent()/irq_domain_free_irqs_parent(): invoke parent irqdomain's alloc/free callbacks. We also changed irq_startup()/irq_shutdown() to invoke irq_domain_activate_irq()/irq_domain_deactivate_irq() to program interrupt controller when start/stop interrupts.

Currently ARM associates an MSI controller with a PCI bus by defining pcibios_add_bus() and using it to call a struct hw_pci.add_bus() method. That method sets the struct pci_bus "msi" member. That's unwieldy and unnecessarily couples MSI with the PCI enumeration code. On ARM, all devices under the same PCI host bridge share an MSI controller, so add an msi_controller pointer to the struct pci_sys_data and implement pcibios_msi_controller() to retrieve it. This is a step toward moving the msi_controller pointer into the generic struct pci_host_bridge.

MSI-X vector Mask Bits are in MSI-X Tables in PCI memory space. Xen PV guests can't write to those tables. MSI vector Mask Bits are in PCI configuration space. Xen PV guests can write to config space, but those writes are ignored. Commit 0e4ccb15 ("PCI: Add x86_msi.msi_mask_irq() and msix_mask_irq()") added a way to override default_mask_msi_irqs() and default_mask_msix_irqs() so they can be no-ops in Xen guests, but this is more complicated than necessary. Add "pci_msi_ignore_mask" in the core PCI MSI code. If set, default_mask_msi_irqs() and default_mask_msix_irqs() return without doing anything. This is less flexible, but much simpler.

Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs.
