Broadwell (BDW) is similar to Haswell (HSW), the preceding processor generation.
Currently, the only difference in their C-state tables is that PC3 max exit latency
is 33usec on HSW and 40usec on BDW.

Prepare second round of input updates for 3.17.
|
|
The khwrngd thread is started when a hwrng device of sufficient
quality is registered. The virtio-rng device is backed by the
hypervisor, and we trust the hypervisor to provide real entropy.
A malicious or badly-implemented hypervisor is a scenario that's
irrelevant -- such a setup is bound to cause all sorts of badness, and a
compromised hwrng is the least of the user's worries.
Given this, we might as well assume that the quality of randomness we
receive is perfectly trustworthy. Hence, we use 100% for the factor,
indicating maximum confidence in the source.

Emmanuel Grumbach fixes Linus's iwlwifi firmware-related log spam.
Rickard Strandqvist does some proper NULL termination after a call
to strncpy.
Ronald Wahl corrects a carl9170 problem with sending URBs with the
wrong endpoint type (resulting in log spam).

xgene_enet_get_ring_size() returns a negative value in case of an error,
but its only caller in xgene_enet_create_desc_ring() currently uses the
return value directly as u32. Instead, check for a negative value first and
error out in case. Also move the call to xgene_enet_get_ring_size() before
devm_kzalloc() so we don't need to free anything in the error path.
This fixes the following issue reported by the Coverity Scanner:
** CID 1231336: Improper use of negative value (NEGATIVE_RETURNS)

Merge leftovers from Andrew Morton:
"A few leftovers.
I have a bunch of OCFS2 patches which are still out for review and
which I might sneak along after -rc1. Partly my fault - I should send
my review pokes out earlier"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
mm: fix CROSS_MEMORY_ATTACH help text grammar
drivers/mfd/rtsx_usb.c: export device table
mm, hugetlb_cgroup: align hugetlb cgroup limit to hugepage size
|
|
The rtsx_usb driver contains the table for the devices it supports but
doesn't export it. As a result, no alias is generated and it doesn't
get loaded automatically.

Pull device tree updates from Grant Likely:
"The branch contains the following device tree changes the v3.17 merge
window:
Group changes to the device tree. In preparation for adding device
tree overlay support, OF_DYNAMIC is reworked so that a set of device
tree changes can be prepared and applied to the tree all at once.
OF_RECONFIG notifiers see the most significant change here so that
users always get a consistent view of the tree. Notifiers generation
is moved from before a change to after it, and notifiers for a group
of changes are emitted after the entire block of changes have been
applied
Automatic console selection from DT. Console drivers can now use
of_console_check() to see if the device node is specified as a console
device. If so then it gets added as a preferred console. UART
devices get this support automatically when uart_add_one_port() is
called.
DT unit tests no longer depend on pre-loaded data in the device tree.
Data is loaded dynamically at the start of unit tests, and then
unloaded again when the tests have completed.
Also contains a few bugfixes for reserved regions and early memory
setup"

Pull device mapper changes from Mike Snitzer:
- Allow the thin target to paired with any size external origin; also
allow thin snapshots to be larger than the external origin.
- Add support for quickly loading a repetitive pattern into the
dm-switch target.
- Use per-bio data in the dm-crypt target instead of always using a
mempool for each allocation. Required switching to kmalloc alignment
for the bio slab.
- Fix DM core to properly stack the QUEUE_FLAG_NO_SG_MERGE flag
- Fix the dm-cache and dm-thin targets' export of the minimum_io_size
to match the data block size -- this fixes an issue where mkfs.xfs
would improperly infer raid striping was in place on the underlying
storage.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2014-08-12
This series contains updates to i40e and e1000e.
Lucas provides a fix for i40e to resolve a compile issue where a header
was missing in the #includes.
Wei Yongjun provides a fix for i40e to resolve a sparse warning, where
a non-static function should be static.
Julia Lawall provides a fix for i40e which was found using Coccinelle,
where there was a typo in the name of the type given to sizeof().
Rickard Strandqvist provides a fix for i40e to replace the use of
strncpy() with strlcpy() to avoid strings that lack null termination.
Jean Sacren provides two e1000e fixes, first is a comment fix and second
removes an excessive space character in a debug message.

The original implementation relies on a loop to check if all inflight
packets are freed. Now we have proper reference counting, there's no
need to use loop anymore.

Reference count the number of packets in host stack, so that we don't
stop the deallocation thread too early. If not, we can end up with
xenvif_free permanently waiting for deallocation thread to unmap grefs.

Originally netif_napi_add was in xenvif_init_queue and netif_napi_del
was in xenvif_deinit_queue, while kthreads were handled in
xenvif_connect and xenvif_disconnect. Move netif_napi_add and
netif_napi_del to xenvif_connect and xenvif_disconnect so that they
reside together with kthread operations.

Enlarge buffer size and check input length properly, so that we don't
misuse -ENOSPC.
Note that command like "kickXXXX" is still allowed, that's one patch for
another day if we really want to be very strict on this.
