5.0.7 regression: .config file not found

5.0.7 regression: .config file not found

Hi folks,

Since 5.0.7 I get a message at build time about a missing .config file.
The result of make oldconfig has been lost somehow. 5.0.6 builds fine.

Sample session is attached.

Thanks for the report.


I think the problem will be fixed
by back-porting the following commit:



commit 175209cce23d6b0669ed5366add2517e26cd75cd
Author: Masahiro Yamada <yamada.masahiro@socionext.com>
Date:   Thu Feb 14 12:05:14 2019 +0900

    kbuild: pkg: use -f $(srctree)/Makefile to recurse to top Makefile

    '$(MAKE) KBUILD_SRC=' changes the working directory back and forth
    between objtree and srctree.

    It is better to recurse to the top-level Makefile directly.

Seems to work. Thanx very much for your fix.

I wonder if this could be included in the 5.0 branch?

Greg,
We have a regression in the build system for v5.0.7

Could you please backport 175209cce23d6b0669ed5366add2517e26cd75cd
to fix the problem?

Thanks.
