Add a selftest for the usage of FPU code in kernel mode.
Currently only implemented for x86. In the future, kernel FPU testing could be unified between the different architectures supporting it.
[ bp:
- Split out from a conglomerate patch, put comments over statements. - run the test only on debugfs write. - Add bare-minimum run_test_fpu.sh, run 1000 iterations on all CPUs by default. - Add conditionally -msse2 so that clang doesn't generate library calls. - Use cc-option to detect gcc 7.1 not supporting -mpreferred-stack-boundary=3 (amluto). - Document stuff so that we don't forget. - Fix: ld: lib/test_fpu.o: in function `test_fpu_get': >> test_fpu.c:(.text+0x16e): undefined reference to `__sanitizer_cov_trace_cmpd' >> ld: test_fpu.c:(.text+0x1a7): undefined reference to `__sanitizer_cov_trace_cmpd' ld: test_fpu.c:(.text+0x1e0): undefined reference to `__sanitizer_cov_trace_cmpd' ]
