parisc: add ftrace (function and graph tracer) functionality This patch adds the ftrace debugging functionality to the parisc kernel. It will currently only work with 64bit kernels, because the gcc options -pg and -ffunction-sections can't be enabled at the same time and -ffunction-sections is still needed to be able to link 32bit kernels.

parisc: Fix ftrace function tracer Fix the FTRACE function tracer for 32- and 64-bit kernel. The former code was horribly broken. Reimplement most coding in assembly and utilize optimizations, e.g. put mcount() and ftrace_stub() into one L1 cacheline.

ftrace: Make CALLER_ADDRx macros more generic Most archs with HAVE_ARCH_CALLER_ADDR have pretty much the same definitions of CALLER_ADDRx(n). Instead of duplicating the code for all the archs, define a ftrace_return_address0() and ftrace_return_address(n) that can be overwritten by the archs if they need to do something different. Instead of 7 macros in every arch, we now only have at most 2 (and actually only 1 as ftrace_return_address0() should be the same for all archs). The CALLER_ADDRx(n) will now be defined in linux/ftrace.h and use the ftrace_return_address*(n?) macros. This removes a lot of the duplicate code.
