Subject[GIT PULL] x86/vdso changes for 4.1
Hi Ingo,

Here are my queued vdso changes for 4.1. There's nothing particularly
interesting. The change "x86, vdso: Remove x32 intermediates during
'make clean'" isn't on any mailing lists, but it's utterly trivial (I
just noticed that one of the other patches here was slightly
incomplete while tidying this up for the pull request).

Please pull into your favorite branch.

My kvmclock rewrite is once again deferred because KVM still hasn't
fixed a bug I need fixed first. Grump. On the off chance that the
bug gets fixed very soon and I can get my patch reviewed quickly, I
just might send you another pull request. Otherwise 4.2 (or 4.3
or...?) it is.

Thanks,
Andy

x86, vdso: Remove x32 intermediates during 'make clean' (2015-03-25
17:55:07 -0700)

----------------------------------------------------------------
x86/vdso changes for 4.1

This boring build stuff plus Denys' deletion of pointless SS code.
The interesting change I have queued up is unlikely to be ready for
4.1, so it's not included here.
