108e5e6833 selftests/powerpc: make sub-folders buildable on their own
Build breaks when executing make with run_tests for sub-folders
under powerpc. This is because, CFLAGS and GIT_VERSION macros are
defined in Makefile of toplevel powerpc folder.

  make: Entering directory '/home/maddy/linux/tools/testing/selftests/powerpc/mm'
  gcc     hugetlb_vs_thp_test.c ../harness.c ../utils.c  -o /home/maddy/selftest_output//hugetlb_vs_thp_test
  hugetlb_vs_thp_test.c:6:10: fatal error: utils.h: No such file or directory
      6 | #include "utils.h"
        |          ^~~~~~~~~
  compilation terminated.

Fix this by adding the flags.mk in each sub-folder Makefile. Also remove
the CFLAGS and GIT_VERSION macros from powerpc/ folder Makefile since
the same is definied in flags.mk

7e0cf1c983 selftests/powerpc: Fix Makefiles for headers_install change
Commit b2d35fa5fc ("selftests: add headers_install to lib.mk")
introduced a requirement that Makefiles more than one level below the
selftests directory need to define top_srcdir, but it didn't update
any of the powerpc Makefiles.

This broke building all the powerpc selftests with eg:

  make[1]: Entering directory '/src/linux/tools/testing/selftests/powerpc'
  BUILD_TARGET=/src/linux/tools/testing/selftests/powerpc/alignment; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C alignment all
  make[2]: Entering directory '/src/linux/tools/testing/selftests/powerpc/alignment'
  ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory
  make[2]: *** No rule to make target '../../../../scripts/subarch.include'.
  make[2]: Failed to remake makefile '../../../../scripts/subarch.include'.
  Makefile:38: recipe for target 'alignment' failed

Fix it by setting top_srcdir in the affected Makefiles.

dbc3f77c2f selftests/powerpc: Consolidate copy/paste test logic
This logic was shared between multiple tests, but now that we have
removed all but one of them we can just move it into that test.

525661ef80 selftests/powerpc: Remove Power9 paste tests
Paste on POWER9 only works to accelerators and not on real memory. So
these tests just generate a SIGILL.

So just delete them.

83039f22ba selftests/powerpc: Remove Power9 copy_unaligned test
This is a test of the ISA 3.0 "copy" instruction. That instruction has
an L field, which if set to 1 specifies that "the instruction
identifies the beginning of a move group" (pp 858). That's also
referred to as "copy first" vs "copy".

In ISA 3.0B the copy instruction does not have an L field, and the
corresponding bit in the instruction must be set to 1.

This test is generating a "copy" instruction, not a "copy first", and
so on Power9 (which implements 3.0B), this results in an illegal
instruction.

So just drop the test entirely. We still have copy_first_unaligned to
test the "copy first" behaviour.

88baa78d1f 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.
