#1235326 — [PATCH 3.14 39/84] IB/mlx4: Use correct SL on AH query under RoCE

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Noa Osherovich <noaos@mellanox.com>

commit 5e99b139f1b68acd65e36515ca347b03856dfb5a upstream.

The mlx4 IB driver implementation for ib_query_ah used a wrong offset
(28 instead of 29) when link type is Ethernet. Fixed to use the correct one.

Fixes: fa417f7b520e ('IB/mlx4: Add support for IBoE')

So there are start sections in memory block not present.  For example:

    memory block : [0x2c18000000, 0x2c20000000) 512M

first three sections are not present.

The current register_mem_sect_under_node() assume first section is
present, but memory block section number range [start_section_nr,
end_section_nr] would include not present section.

For arch that support vmemmap, we don't setup memmap for struct page
area within not present sections area.

So skip the pfn range that belong to absent section.

#1235329 — [PATCH 3.14 04/84] tg3: Fix temperature reporting

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Jean Delvare <jdelvare@suse.de>

commit d3d11fe08ccc9bff174fc958722b5661f0932486 upstream.

The temperature registers appear to report values in degrees Celsius
while the hwmon API mandates values to be exposed in millidegrees
Celsius. Do the conversion so that the values reported by "sensors"
are correct.

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Jeffery Miller <jmiller@neverware.com>

commit 09bfda10e6efd7b65bcc29237bee1765ed779657 upstream.

With the radeon driver loaded the HP Compaq dc5750
Small Form Factor machine fails to resume from suspend.
Adding a quirk similar to other devices avoids
the problem and the system resumes properly.

#1235332 — [PATCH 3.14 26/84] NFS: nfs_set_pgio_error sometimes misses errors

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Trond Myklebust <trond.myklebust@primarydata.com>

commit e9ae58aeee8842a50f7e199d602a5ccb2e41a95f upstream.

We should ensure that we always set the pgio_header's error field
if a READ or WRITE RPC call returns an error. The current code depends
on 'hdr->good_bytes' always being initialised to a large value, which
is not always done correctly by callers.
When this happens, applications may end up missing important errors.
