Subject[REVIEW][PATCH 00/22] Simplifying siginfo users

This patchset is almost completely updating the various pieces of
architecture code from filling out a struct siginfo and then calling
force_sig_info. To using the helper force_sig_fault instead. Which
takes the values that would have gone in siginfo as arguments.

As the diffstat below shows this noticeable reduces the amount of code.

There are a couple of minor and straight forward bug fixes as well
that I came across while working on the aforementioned changes.

This applies on my last round of siginfo changes simply to remove the
possibility of conflicts. The changes should be semantically separate.

I intend to merge these changes through my siginfo tree. If you have
any objections or would prefer to carry these changes in your
architecture trees please let me know.

The changes are also available at:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git siginfo-review2
