drm/i915: Hook up Ivybridge eDP
This fixes eDP link-training failures and cases where all voltage swing
/pre-emphasis levels were tried and failed during clock recovery and -
as a fallback - we go on to do channel equalization with the last voltage
swing/pre-emphasis level which will succeed. Both issues can lead to a
blank screen.

drivers/platform/olpc/olpc-ec.c: initialise earlier
Being a low-level component, various drivers (e.g. olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe. Therefore the OLPC EC driver must be initialised before other
drivers try to use it. This was the case until it was recently moved
out of arch/x86 and restructured around commits
ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and
85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").
Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.
Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC. The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

Revert "genetlink: fix family dump race"
This reverts commit
58ad436fcf49810aa006016107f494c9ac9013db.
It turns out that the change introduced a potential deadlock
by causing a locking dependency with netlink's cb_mutex. I
can't seem to find a way to resolve this without doing major
changes to the locking, so revert this.
