+Subject: x86: disable image size check for test builds
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+commit 00a241f528427b63c415a410293b86e66098888e upstream.
+
+64-bit allyesconfig builds fail with
+
+x86_64-linux-ld: kernel image bigger than KERNEL_IMAGE_SIZE
+
+Bisect points to commit 6f110a5e4f99 ("Disable SLUB_TINY for build
+testing") as the responsible commit.  Reverting that patch does indeed fix
+the problem.  Further analysis shows that disabling SLUB_TINY enables
+KASAN, and that KASAN is responsible for the image size increase.
+
+Solve the build problem by disabling the image size check for test
+builds.
