[Devel] [PATCH hci-8.1 0/2] ms/kbuild: GCOV follow-ups to the prefer-atomic fix

[Konstantin Khorenko <khorenko@virtuozzo.com>]

Two follow-ups to commit 6e1a837a05d4 ("ms/gcov: use atomic counter
updates to fix concurrent access crashes"). Peter Oberparleiter suggested
them while reviewing the upstream patch.

Both are taken from the akpm/mm tree, branch mm-nonmm-stable, and are not
in Linus's tree yet:

  4719c9264131 kbuild: use $(CFLAGS_GCOV) in the prefer-atomic try-run test
  f541906e89f9 kbuild: move GCOV flags to scripts/Makefile.gcov

- Patch 1 makes the try-run test compile with $(CFLAGS_GCOV) instead of a
  copy of its flags, so the test also sees -fno-tree-loop-im. The outcome
  of the test is unchanged.
- Patch 2 moves the CFLAGS_GCOV block into scripts/Makefile.gcov,
  included via include-$(CONFIG_GCOV_KERNEL) like the KCOV and KASAN
  makefiles. Builds without GCOV no longer run the try-run.

Patch 2 had a context conflict in Makefile: the CFLAGS_GCOV block has
different neighbours in this tree. The resolution is noted in the commit.
