custom kernel build with patch

[Damian Ivanov]

Hello,

I am trying to build the fedora kernel with the muqss patch and the
patches for the surface devices.
To start I tried to build it only with the muqss patch. So tried as
well with fedpkg as well as a plain rpmbuild but both hang at the same
stage.
I enpacked the kernel.src.rpm, fetched the latest muqss patch and
added it in the kernel.spec.
Also I did set %define with_baseonly 1 to build only non-debug x86_64
Trying to build the kernel with rpmbuild -ba kernel.spec will fail at
the stage of
process_configs.sh that compains about config options being unset
(and
.git/rebase-apply/patch:7590: space before tab in indent.
  cpu = i;
.)
So I try to add them to all config's but when building I get:
Error: Mismatches found in configuration files
Found CONFIG_RQ_ALL=is not set after generation, had CONFIG_RQ_ALL=n
in Source tree
Found CONFIG_RQ_SMP=is not set after generation, had CONFIG_RQ_SMP=n
in Source tree
Found CONFIG_RQ_SMT=is not set after generation, had CONFIG_RQ_SMT=n
in Source tree
Found CONFIG_RQ_NONE=is not set after generation, had CONFIG_RQ_NONE=n
in Source tree


What is the correct way to build the fedora kernel with a custom patch added?
