This fixes a regression introduced by commit cdcb725c05fe ("Btrfs: check
if there is enough space for balancing smarter"). We can't do 64-bit
divides on 32-bit architectures.In cases where we need to divide/multiply by 2 we should just left/right
shift respectively, and in cases where theres N number of devices use
do_div. Also make the counters u64 to match up with rw_devices.

The label outnodev is only used when kzalloc has not yet taken place or has
failed, so there is no need for the call for kfree under this label.A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)//
@@
identifier x;
expression E1!=0,E2,E3,E4;
statement S;
iterator I;
@@(
if (...) { ... when != kfree(x)
when != x = E3
when != E3 = x
* return ...;

snd_hda_get_conn_index() returns a negative value while the current code

Currently HD-audio driver shows the all error ELD byte as an error
in the kernel message. This is annoying when the video driver doesn't
set the correct ELD from the beginning. e.g. radeon sends a zero-byte
data, but we still check ELD with the fixed 128 byte as a workaround
for some broken devices, it spews 128-times errors.For avoiding this, the driver aborts reading when the first byte is
invalid. In such a case, the whole data is certainly invalid.Signed-off-by: Takashi Iwai

drm/i915: set GFX_MODE to pre-Ivybridge default value even on Ivybridge -
There is a race between ext4 buffer write and direct_IO read with
dioread_nolock mount option enabled. The problem is that we clear
PageWriteback flag during end_io time but will do
uninitialized-to-initialized extent conversion later with dioread_nolock.
If an O_direct read request comes in during this period, ext4 will return
zero instead of the recently written data.This patch checks whether there are any pending uninitialized-to-initialized
extent conversion requests before doing O_direct read to close the race.
Note that this is just a bandaid fix. The fundamental issue is that we
clear PageWriteback flag before we really complete an IO, which is
problem-prone. To fix the fundamental issue, we may need to implement an
extent tree cache that we can use to look up pending to-be-converted extents.Signed-off-by: Jiaying Zhang

Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that
MI_FLUSH would flush the TLBs in addition to the rest of the caches
indicated in the MI_FLUSH command. However starting with Ivybridge, the
register defaults to 0x2800 out of reset, meaning that to invalidate the
TLB we need to use PIPE_CONTROL. Since we're not doing that yet, go
back to the old default so things work.v2: don't forget to actually *clear* the new bit
