Add support for emulating the new CMP.condn.fmt R6 instructions and return SIGILL for the old C.cond.fmt if R2 emulation is not enabled since it's not supported by R6. The functionality of the new CMP.condn.fmt is the following one: If the comparison specified by the condn field of the instruction is true for the operand values, the result is true; otherwise, the result is false. If no exception is taken, the result is written into FPR fd; true is all 1s and false is all 0s repeated the operand width of fmt. All other bits beyond the operand width fmt are UNPREDICTABLE.

Currently the Octeon Ethernet driver hardcodes the mapping between interface/port and IPD port number. Since we have generic helpers for the very same purpose, we might as well use them instead. This prevents having the same information in multiple places. Signed-off-by:

The Pistachio SoC provides four general purpose timers, and allow to implement a clocksource driver. This driver can be used as a replacement for the MIPS GIC and MIPS R4K clocksources and sched clocks, which are clocked from the CPU clock. Given the general purpose timers are clocked from an independent clock, this new clocksource driver will be useful to introduce CPUFreq support for Pistachio machines. Signed-off-by:

Now that we're ready to enable COMMON_CLK for GIC platforms do so for Malta and SEAD3. The only other user of the GIC Pistachio does already do so. [ralf@linux-mips.org: Rewrite the commit message because applied in the right order there is no breakage thus no fix required.] Signed-off-by:

This is preparation work for the introduction of clockevent frequency update with a clock notifier. This is only possible when the device is passed a clk struct, so let's split the legacy and devicetree initialization. Reviewed-by:

For the clock to be used (e.g. get its rate through clk_get_rate) it should be prepared and enabled first. Also, while the clock is enabled the driver must hold a reference to it, so let's remove the call to clk_put. Reviewed-by:

Rather than saving the scalar FP or vector context in the assembly resume function, reuse the existing C code we have in fpu.h to do exactly that. This reduces duplication, results in a much easier to read resume function & should allow the compiler to optimise out more MSA code due to is_msa_enabled()/cpu_has_msa being known-zero at compile time for kernels without MSA support.
