2.6.33-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Anton Blanchard <an...@samba.org>
commit 51d33021425e1f905beb4208823146f2fb6517da upstream.
Return -EAGAIN when we get H_BUSY back from the hypervisor. This
makes the hvc console driver retry, avoiding dropped printks.
