Some of git's whitespace fixup option corrupts the patches by (at least) stripping trailing spaces (which are present for empty lines in context) and changing leading <space><tab> into just <tab>. `patch(1)` used by the build here seems to tolerate this, but `git am` and/or `git apply` do not. Fix this up by running git am and at each failure point (i.e. every patch) applying the relevant patch using `patch(1)` (which works because `git am` was unable to even partially apply the patches) before regenerating the whole lot with `git format-patch`.

Temporary non modular kernel config for pinata alpha
TODO: build with Alpine and/or use Alpine kernels - needs some patches.
The build is mostly silent. To view the output use docker log -f <containerid>. The build creates multiple containers, so multiple
invocations may be necessary. To view the full build output one may also invoke docker build . and then copy the build artefacts from the image afterwards.
To build with various debug options enabled, build the kernel with
make DEBUG=1. The options enabled are listed in kernel_config.debug. This allocates a significant amount of memory on boot and you may need to adjust the kernel config on some systems. Specifically:
--- a/alpine/kernel/kernel_config
