Feature freeze exception for kpatch 0.5.0

[Ben Romer]

The kpatch package needs to be updated to support bionic.

The updated package contains fixes for these bugs:
- kpatch-dkms 0.3.2-1ubuntu4.2: kpatch kernel module failed to build (#1665613)
- kpatch ADT test failures with 4.10 kernels (#1659581)

The upstream source for kpatch does not use changelogs. The git commit record can be
found at:
https://github.com/dynup/kpatch/commits/0.5.0

This package update contains all upstream commits between v0.3.2 and 0.5.0, as well as a set of
Ubuntu-specific changes:
- to safely patch ubuntu kernels, we must build the way ubuntu kernels are
  built and not just use the mainline kernel's makefile.
- we must use the paths for binaries where they are installed via debian package.
- support is added for ubuntu's included external packages. (ZFS)
- support is added for ubuntu kernel flavors. (generic, lowlatency)

Testing that was performed: (logs will be attached for all items)
- building using pbuilder and installing and removing the debians
- building the DKMS module and installing it
- building a livepatch module from a source patch

The attachment "simple livepatch test patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

(talking to myself here) For reference, the new features in this release:

 * Basic ppc64le support
 * kpatch utility support for the livepatch consistency model:
  * kpatch load automatically signals stalled processes after a timeout
  * kpatch list shows stalled processes
  * kpatch signal signals stalled processes
 * kpatch-build has some new options:
  * multiple source patches can be combined into a single binary patch module
  * -n|--name option for giving a custom name to the patch module
  * additional -d options for more verbose debug modes
 * The module prefix is now either livepatch- or kpatch- depending on the underlying patching technology

[Łukasz Zemczak (sil2100)]

Ok, looks good. The package is not seeded right now so it shouldn't be a problem - also, seeing that the last release of kpatch for Ubuntu was in yakkety, it's about time to get a new version rolled out. FFe approved.

Do you think if we could also get the new version released for Debian? The package is now marked for auto-removal due to inactivity (and no one being around to get the new version uploaded). I guess we might want to poke Chris about that...

[Ben Romer (bromer)]

Thank you for approving this! :)

I will test my package on Debian and try to get in touch with Chris again.
