Bug Description

== 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.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
