day 01:

I made the git repository on github and committed the first draft of kpatch.
I will go on working on it in the next days. and starting to think the
design of service.
https://github.com/aliceinwire/kernel-live-patch
I got into this kpatch problem: https://github.com/dynup/kpatch/issues/675


day 02:

I could fix the problem of the kpatch issue https://github.com/dynup/
kpatch/issues/675 .
Unfortunately as now, i could fix it only with a workaround.
The workaround is forcing -O1 in src_prepare with replace-flags -O? -O1
But now I'm in a new make problem.
------------------------

make[2]: Entering directory '/var/tmp/portage/sys-kernel/
kpatch-0.4.0/work/kpatch-0.4.0/kmod/core'
make -C /lib/modules/4.4.44-gentoo/build M=/var/tmp/portage/sys-kernel/

---------------------------------
I will go on fixing this tomorrow

I commited the first kpatch version here https://github.com/
aliceinwire/kernel-live-patch
and updated the kpatch bug https://github.com/dynup/kpatch/issues/675


day 03:

Fixed the problem of the other day. The kpatch Makefile is calling
the /usr/src/linux/ Makefile and because is presetting arch=amd64
it fail to build the package.
I have unset it before making the package so it can build the package
without errors.
I had sended a pull request for review (please review it):
https://github.com/gentoo/gentoo/pull/4844
