Public bug reported:
== SRU REQUEST, XENIAL, YAKKETY + ZESTY ==
Running the autotest client ubuntu_kernel_selftests tests hang on i386
because of a bug in the ftracing, resolved with upstream fix:
commit 847fa1a6d3d00f3bdf68ef5fa4a786f644a0dd67
ftrace/x86_32: Set ftrace_stub to weak to prevent gcc from using short jumps to
it
Although these have fixes ready to come down into -stable, lets SRU
these in sooner than later.
== Test ==
Without the fix, the i386 kernel self tests always hang on the ftracing
tests. With the fix, it works perfectly.
== Regression potential ==
Minimal, this is a tried and tested patch, plus it matches the fixes in
the amd64 paths that were not ported over to the i386 paths which this
fix now addresses.
