[14/21] Staging: android: binder: Dont call dump_stack in binder_vma_open

[Greg KH]

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

------------------

From: Arve Hjønnevåg <a...@android.com>

commit 3c1b86f17068cf6476fb2d022b9c8b44dedea2e5 upstream.

If user-space partially unmaps the driver, binder_vma_open
would dump the kernel stack. This is not a kernel bug however
and will be treated as if the whole area was unmapped once
binder_vma_close gets called.
