selftests: Add test of PMU instruction counting on powerpc This commit adds a test of instruction counting using the PMU on powerpc. Although the bulk of the code is architecture agnostic, the code needs to run a precisely sized loop which is implemented in assembler.

selftests: remove duplicated all and clean target Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt.

selftests/powerpc: Don't ignore errors from sub Makefiles Currently we ignore errors from our sub Makefiles. We inherited that from the top-level selftests Makefile which aims to build and run as many tests as possible and damn the torpedoes. For the powerpc tests we'd instead like any errors to fail the build, so we can automatically catch build failures. We can achieve the best of both worlds by using -k, which tells make to keep building when it hits an error, but still reports the error.

selftests: Add install support for the powerpc tests The bulk of the selftests are actually below the powerpc sub directory. This adds support for installing them, when on a powerpc machine, or if ARCH and CROSS_COMPILE are set appropriately. This is a little more complicated because of the sub directory structure under powerpc, but much of the common logic in lib.mk is still used. The net effect of the patch is still a reduction in code.
