2014-11-24MIPS: Loongson: cs5536_pci: Add a missing includeAaro Koskinen
Add a missing include to get rid of the following sparse warnings: warning: symbol 'cs5536_pci_conf_write4' was not declared. Should it be static? warning: symbol 'cs5536_pci_conf_read4' was not declared. Should it be static?

2014-11-24MIPS: IP22/IP32: Add line to arch/mips/Makefile archhelp about vmlinux.32Joshua Kinard
Building a 64bit kernel for the SGI O2 (IP32) and the SGI Indy (IP22) uses the 'vmlinux.32' target, which converts the output 64-bit 'vmlinux' image into a 32-bit wrapped image. This is needed for certain revisions of the IP22 and IP32 ARCS PROMs to boot correctly, but this target is missing from the 'archhelp' info that is emitted by 'make help'.

2014-11-24MIPS: lib: mips-atomic.c: Remove obsolete ifdeferyMarkos Chandras
Having #ifdefs just to guard comments is not really helpful so drop them. Moreover, the code wasn't really reached anyway since there is a #ifndef CONFIG_CPU_MIPSR2 on the top of the file.

2014-11-24MIPS: Octeon: Delete potentially dangerous feature checksAaro Koskinen
We should not need to read fuses during normal operation, also the current code has issues with that (not safe for concurrent access). Since there are no in-kernel users for these, just delete them. Drivers should not need such OCTEON_HAS_FEATURE mechanism in any case, instead the information should be passed via device tree.

2014-11-24MIPS: oprofile: Backtrace: don't fail on leaf functionsAaro Koskinen
Continue the backtrace if we cannot find SP adjustment and RA save. In that case, just assume the current RA. This allows us to get samples of frequent callers of e.g. GLIBC memset().

2014-11-24MIPS: oprofile: Enable backtrace on timer-based profilingAaro Koskinen
Allow unsupported CPU types to use backtrace with timer-based profiling. Some CPUs (notably OCTEON) lack architecture-specific oprofile driver. In such case oprofile can fallback to timer-based mode, and arch code can still provide the backtrace functionality. So just set up the backtrace hook always.
