For assembly code there are several long load and store defines already.
The one that's missing is the typical stack store, stdu/stwu.
So let's add that define as well, making my KVM code happy.

Here is the new patch of V4 against tip/master of April 13th
if anyone wants to try it.
ChangeLog V4:
1) Based on Ingo's comments, I added help information around kvm
such like command-list.txt and perf-kvm.txt.
2) Added guest process id at the tail of kernel dso long
Below is the kernel patch to enable perf to collect guest os statistics.
Joerg,
Would you like to add support on svm? I don't know the exact point to trigger
NMI to host with svm.
See below code with vmx:

Since gfn is not changed in the for loop, we do not need to call

To have better testing over -stable kernel KVM Avi decided to drop
the Cc: sta...@kernel.org tag (which meant such patches are included
directly in the process by Greg), to instead queue patches in
kvm-updates/2.6.3x branches and autotest them before submission.
So to avoid automatic inclusion,
The boot option is missing from the documentation for the -drive parameter.
If there is a better way to descibe it, I'm all ears.
