Subject: [PATCH 00/29] objtool sync up for the stable 4.9.y tree
There are pros and cons of dealing with tools in the kernel directory.
The pros are the fact that development happens fast, and new features
can be added to the kernel and the tools at the same times. The cons
are when dealing with backported kernel patches, it can be necessary to
backport parts of the tool changes as well.
For 4.9.y so far, we have backported individual patches. That quickly
breaks down when there are minor differences between how backports were
handled, so grabbing 40+ patch long series can be difficult, not
impossible, but really frustrating to attempt.
To help mitigate this mess, this patch series works to sync up the
objtool code with the version that is currently in 4.14.47. This
required a number of objtool old patches to be backported, a single big
"sync the world" patch, and a lot of include file updates to get
everything all working properly as well as some minor fixes for build
warnings.
And at the end of this series, is a set of backported objtool patches
for gcc-8 that was the main reason this whole patch series was created.
They applied just fine, being the identical version that goes into the
4.14.y stable tree, so it feels like the backport was successful.
This has survivied my limited testing, and as the codebase is identical
to 4.14.47, I'm pretty comfortable dropping this big change in here in
4.9.y. Hopefully all goes well...
If anyone has any objections to this patch series, or finds anything I
messed up on, please let me know.
thanks,
greg k-h
