The GIC IPI functions aren't necessarily specific to the "CMP framework" SMP implementation, and will be used elsewhere in a subsequent commit. This patch adds cleaned up GIC IPI functions to a separate file which is compiled when a new CONFIG_MIPS_GIC_IPI Kconfig symbol is selected, and selects that symbol for CONFIG_MIPS_CMP.

The kvm_mips_init_shadow_tlb() function is called from kvm_arch_vcpu_init() and initialises entries 0 to current_cpu_data.tlbsize-1 of the virtual cpu's shadow_tlb[64] array. However newer cores with FTLBs can have a tlbsize > 64, for example the ProAptiv I'm testing on has a total tlbsize of 576. This causes kvm_mips_init_shadow_tlb() to overflow the shadow_tlb[64] array and overwrite the comparecount_timer among other things, causing a lock up when starting a KVM guest. Aside from kvm_mips_init_shadow_tlb() which only initialises it, the shadow_tlb[64] array is only actually used by the following functions: - kvm_shadow_tlb_put() & kvm_shadow_tlb_load() These are never called. The only call sites are #if 0'd out. - kvm_mips_dump_shadow_tlbs() This is never called. It was originally added for trap & emulate, but turned out to be unnecessary so it was disabled. So instead of fixing the shadow_tlb initialisation code, lets just remove the shadow_tlb[64] array and the above functions entirely. The only functional change here is the removal of broken shadow_tlb initialisation. The rest just deletes dead code.

Add MSI chip and MSIX chip definitions. For MSI, we map the link interrupt to a MSI link IRQ which will do a second level of dispatch based on the MSI status register. The MSI chip definitions use the MSI enable register to enable and disable the MSI irqs. For MSI-X, we split the 32 available MSI-X vectors across the four PCIe links (8 each). These PIC interrupts generate an IRQ per link which uses a second level dispatch as well. The MSI-X chip definition uses the standard functions to enable and disable interrupts.

This patch causes the kernel to mux the SERIRQ interrupt to the SERIRQ pin of the PIIX4 and to enable that interrupt. The kernel depends upon the interrupt when using the SuperIO UARTs (ttyS0 & ttyS1) but previously would not configure it, instead relying upon the bootloader having done so. If that is not the case then the typical result is that the system appears to hang once it reaches userland as no output is displayed on the UART.
