2014-02-09locking/mcs: Order the header files in Kbuild of each architecture in ↵Tim Chen

Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.

2014-01-24MIPS: KVM: remove shadow_tlb codeJames Hogan
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.

2014-01-23MIPS: Malta: mux & enable SERIRQ interruptPaul Burton
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.
