slim_ngd: Handle error flags before handling SENT flag

It's possible that error flags were set alongwith SENT flag for
TX transaction status. In such a scenario, error flag status should
be handled (and SENT flag should be cleared). Move error-flag
handling ahead of SENT flag handling to avoid interrupt being called
twice, and completion being set twice.

msm: kgsl: Protect CP_STATE_DEBUG_INDEX

Put CP_STATE_DEBUG_INDEX and CP_STATE_DEBUG_DATA under protection
to keep it from being written from an IB1. Doing so however opens
up a subtle "feature" in the microcode: memory read opcodes turn off
protected mode in the microcode to do the read and then turns it
back on regardless of the initial state. This is a problem if the
memory read happens while protected mode is turned off and then we
try to access a protected register which then complains and goes boom.

To account for this irregularity explicitly turn back off protected
mode in all the places where we know this will be a problem.

net/l2tp: don't fall back on UDP [get|set]sockopt

The l2tp [get|set]sockopt() code has fallen back to the UDP functions
for socket option levels != SOL_PPPOL2TP since day one, but that has
never actually worked, since the l2tp socket isn't an inet socket.

As David Miller points out:

  "If we wanted this to work, it'd have to look up the tunnel and then
   use tunnel->sk, but I wonder how useful that would be"

Since this can never have worked so nobody could possibly have depended
on that functionality, just remove the broken code and return -EINVAL.

ion: shrink highmem pages on kswapd

The patch is ported from Linux3.16, since the directory structure was
changed, I merged the patch manually.

Below is the patch detail information:

From 0cd2dc4db3ba23ff8ab38b8ae81b126626f795d5 Mon Sep 17 00:00:00 2001
From: Heesub Shin <heesub.shin@samsung.com>
Date: Wed, 28 May 2014 15:52:59 +0900
Subject: staging: ion: shrink highmem pages on kswapd

ION system heap keeps pages in its pool for better performance. When the
system is under memory pressure, slab shrinker calls the callback
registered and then the pages pooled get freed.

When the shrinker is called, it checks gfp_mask and determines whether
the pages from highmem need to be freed or the pages from lowmem.
Usually, slab shrinker is invoked on kswapd context which gfp_mask is
always GFP_KERNEL, so only lowmem pages are released on kswapd context.
This means that highmem pages in the pool are never reclaimed until
direct reclaim occurs. This can be problematic when the page pool holds
excessive amounts of highmem.

For now, the shrinker callback cannot know exactly which zone should be
targeted for reclamation, as enough information are not passed to. Thus,
it makes sense to shrink both lowmem and highmem zone on kswapd context.
