# commit 7af08140979a6e7e12b78c93b8625c8d25b084e2
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Mon Apr 19 15:08:49 2021 -0700

#     Revert "gcov: clang: fix clang-11+ build"
#     
#     This reverts commit 04c53de57cb6435738961dace8b1b71d3ecd3c39.
#     
#     Nathan Chancellor points out that it should not have been merged into
#     mainline by itself. It was a fix for "gcov: use kvmalloc()", which is
#     still in -mm/-next. Merging it alone has broken the build.
