Public bug reported:
== Justification ==
There is a powerpc/alignment_handler available in the upstream for PowerPC
self-testing tool.
Bring this in to cover more bits in the ubuntu_kernel_selftest test suite.
== Fix ==
* 8d191587 (selftests/powerpc: Add alignment handler selftest)
* ecdf06e1 (selftests/powerpc: Fix to use ucontext_t instead of struct ucontext)
Both of them can be cherry-picked into Bionic kernel.
The second patch is essential to fix a build error.
It's already available in Cosmic and onward.
== Test ==
Test was successfully built and passed on a Power9 node with Bionic kernel:
