KVM: PPC: Book3S HV: Enable IRQ bypass

Add the irq_bypass_add_producer and irq_bypass_del_producer functions. These functions get called whenever a GSI is being defined for a guest. They create/remove the mapping between host real IRQ numbers and the guest GSI. Add the following helper functions to manage the passthrough IRQ map. kvmppc_set_passthru_irq() Creates a mapping in the passthrough IRQ map that maps a host IRQ to a guest GSI. It allocates the structure (one per guest VM) the first time it is called. kvmppc_clr_passthru_irq() Removes the passthrough IRQ map entry given a guest GSI. The passthrough IRQ map structure is not freed even when the number of mapped entries goes to zero. It is only freed when the VM is destroyed. [paulus@ozlabs.org - modified to use is_pnv_opal_msi() rather than requiring all passed-through interrupts to use the same irq_chip; changed deletion so it zeroes out the r_hwirq field rather than copying the last entry down and decrementing the number of entries.] Signed-off-by: Suresh Warrier <warrier@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
