+Subject: gcov: disable for COMPILE_TEST
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit cc622420798c4bcf093785d872525087a7798db9 upstream.
+
+Enabling gcov is counterproductive to compile testing: it significantly
+increases the kernel image size, compile time, and it produces lots
+of false positive "may be used uninitialized" warnings as the result
+of missed optimizations.
+
+This is in line with how UBSAN_SANITIZE_ALL and PROFILE_ALL_BRANCHES
+work, both of which have similar problems.
+
+With an ARM allmodconfig kernel, I see the build time drop from
+283 minutes CPU time to 225 minutes, and the vmlinux size drops
+from 43MB to 26MB.
