I assume YES, uprobe is a useful feature in mainline, arm support is
quite needed as a large user base, like
cellphone, telecom basestation, etc, a lot of company and users are
waiting for this feature.

I'm not quite sure if there already have some similar arm porting work
on uprobe(that's the purpose of this mail),
but if there don't have any arm uprobe availabe in systemtap or other
project, I think I can try it.
