In light of the commit 16f77de8 (Revert "MIPS: Save/restore MSA context around signals") the MSA support in the kernel is incomplete. Until the replacement for the former sigcontext changes is agreed upon and in tree, mark MSA experimental & disable it by default. MSA is only implemented by one CPU supported by the kernel, the P5600. The P5600 is a 32 bit core, and thus MSA can only be used when the experimental CONFIG_MIPS_O32_FP64_SUPPORT option is enabled. Therefore MSA is only being used in experimental settings anyway and this change doesn't actually make any difference beyond clarifying the state of MSA support.

This patch introduces common clock framework integration for all configurable on-chip clocks on Alchemy chips: - 2 or 3 PLLs which generate integer multiples of the root rate 12MHz, - 6 dividers which take one of the 3 PLLs as input and divide their rate by either multiples of 2 or 1 (Au1300). - another bank of up to 6 muxes which take either one of the 6 above dividers or one of the PLLs directly and divide their rate further by 1, 2, 3 or 4. - a few other sources which are used by onchip peripherals and are informational. This implementation will take the clock tree as it was set up by boot firmware: all in-kernel boards should continue to work without having to set up the clock tree in board code. CLK_IGNORE_DISABLED will be removed once all drivers have been converted.

The KVM_HOST_FREQ Kconfig symbol was used by KVM guest kernels to override the timer frequency calculation to a value based on the host frequency. Now that the KVM timer emulation is implemented independent of the host timer frequency and defaults to 100MHz, adjust the working of CONFIG_KVM_HOST_FREQ to match. The Kconfig symbol now specifies the guest timer frequency directly, and has been renamed accordingly to KVM_GUEST_TIMER_FREQ. It now defaults to 100MHz too and the help text is updated to make it clear that a zero value will allow the normal timer frequency calculation to take place (based on the emulated RTC).

This patch adds support for offlining CPUs via hotplug when using the CONFIG_MIPS_CPS SMP implementation. When a CPU is offlined one of 2 things will happen: - If the CPU is part of a core which implements the MT ASE and there is at least one other VPE online within that core then the VPE will be halted by settings its TCHalt bit. - Otherwise if supported the core will be powered down via the CPC. - Otherwise the CPU will hang by executing an infinite loop. Bringing CPUs back online is then a process of either clearing the appropriate VPEs TCHalt bit or powering up the appropriate core via the CPC. Throughout the process the struct core_boot_config vpe_mask field must be maintained such that mips_cps_boot_vpes will start & stop the correct VPEs.

This patch adds code to generate entry & exit code for various low power states available on systems based around the MIPS Coherent Processing System architecture (ie. those with a Coherence Manager, Global Interrupt Controller & for >=CM2 a Cluster Power Controller). States supported are: - Non-coherent wait. This state first leaves the coherent domain and then executes a regular MIPS wait instruction. Power savings are found from the elimination of coherency interventions between the core and any other coherent requestors in the system. - Clock gated. This state leaves the coherent domain and then gates the clock input to the core. This removes all dynamic power from the core but leaves the core at the mercy of another to restart its clock. Register state is preserved, but the core can not service interrupts whilst its clock is gated. - Power gated. This deepest state removes all power input to the core. All register state is lost and the core will restart execution from its BEV when another core powers it back up. Because register state is lost this state requires cooperation with the CONFIG_MIPS_CPS SMP implementation in order for the core to exit the state successfully. The code will detect which states are available on the current system during boot & generate the entry/exit code for those states. This will be used by cpuidle & hotplug implementations.

Based on Markos Chandras <Markos.Chandras@imgtec.com> patch https://patchwork.linux-mips.org/patch/6719/ which while very similar did no longer apply cleanly when I tried to merge it plus some additional post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to merge once upon a time.

If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available.
