Pull device mapper updates from Mike Snitzer:
- Significant DM thin-provisioning performance improvements to meet
performance requirements that were requested by the Gluster
distributed filesystem.
Specifically, dm-thinp now takes care to aggregate IO that will be
issued to the same thinp block before issuing IO to the underlying
devices. This really helps improve performance on HW RAID6 devices
that have a writeback cache because it avoids RMW in the HW RAID
controller.
- Some stable fixes: fix leak in DM bufio if integrity profiles were
enabled, use memzero_explicit in DM crypt to avoid any potential for
information leak, and a DM cache fix to properly mark a cache block
dirty if it was promoted to the cache via the overwrite optimization.
- A few simple DM persistent data library fixes
- DM cache multiqueue policy block promotion improvements.
- DM cache discard improvements that take advantage of range
(multiblock) discard support in the DM bio-prison. This allows for
much more efficient bulk discard processing (e.g. when mkfs.xfs
discards the entire device).
- Some small optimizations in DM core and RCU deference cleanups
- DM core changes to suspend/resume code to introduce the new internal
suspend/resume interface that the DM thin-pool target now uses to
suspend/resume active thin devices when the thin-pool must
suspend/resume.
This avoids forcing userspace to track all active thin volumes in a
thin-pool when the thin-pool is suspended for the purposes of
metadata or data space resize.

"The main thing this time around is support for suspend mode
configuration from DT which will enable some very useful power savings
on systems where we can't rely on the bootloader configuration. We
still don't really support dynamic configuration of this at runtime,

Summary:
- Support for specifying the target regulation mode and voltage
during system suspend via DT, enabling power savings in that mode.
- Reduce the default verbosity of the logging on boot, improving boot
times especially for systems with very large numbers of regulators.
- Lots of cleanups and fixes for Maxim PMIC drivers.

INT3400 currently supports only one policy, which can't be changed.
This change exports all available policies (uuids) to user space and
allow this to be changed.
It introduces an attribute group uuids in INT3400 platform driver.
There are two attributes exposed:
- available_uuids
- current_uuid
User space can set current_uuid via this interface to one of the
available uuids. The uuid change is communicated to firmware, only
when the current zone mode is changed to "enabled". So the ideal
sequence should be
- set INT3400 zone mode to "disabled"
- change current_uuid
- set INT3400 zone mode to "enabled"

In recent testing I had disabled CONFIG_IP_MULTIPLE_TABLES and as a result
when I ran "cat /proc/net/fib_trie" the main trie was displayed multiple
times. I found that the problem line of code was in the function
fib_trie_seq_next. Specifically the line below caused the indexes to go in
the opposite direction of our traversal:
h = tb->tb_id & (FIB_TABLE_HASHSZ - 1);
This issue was that the RT tables are defined such that RT_TABLE_LOCAL is ID
255, while it is located at TABLE_LOCAL_INDEX of 0, and RT_TABLE_MAIN is 254
with a TABLE_MAIN_INDEX of 1. This means that the above line will return 1
for the local table and 0 for main. The result is that fib_trie_seq_next
will return NULL at the end of the local table, fib_trie_seq_start will
return the start of the main table, and then fib_trie_seq_next will loop on
main forever as h will always return 0.
The fix for this is to reverse the ordering of the two tables. It has the
advantage of making it so that the tables now print in the same order
regardless of if multiple tables are enabled or not. In order to make the
definition consistent with the multiple tables case I simply masked the to
RT_TABLE_XXX values by (FIB_TABLE_HASHSZ - 1). This way the two table
layouts should always stay consistent.

Intel Wired LAN Driver Updates 2014-12-06
This series contains updates to i40e and i40evf.
Shannon provides several patches to cleanup and fix i40e. First removes
an unneeded break statement in i40e_vsi_link_event(). Then removes
some debug messages that really do not give any useful information and
ends up getting printed every service_task loop, which fills the logfile
with noise when AQ tracing is enabled. Updates the aq_cmd arguments to
use %i which is much more forgiving and user friendly than the more
restrictive %x, or %d. Fixes the netdev_stat macro, where the old
xxx_NETDEV_STAT() macro was defined long before the newer
rtnl_link_stats64 came into being, and just never got updated.
Getting the pf_id from the function number had an issue when
when the PF was setup in passthru mode, the PCI bus/device/function
was virtualized and the number in the VM is different from the number in
the bare metal. This caused HW configuration issues when the wrong pf_id
was used to set up the HMC and other structures. The PF_FUNC_RID register
has the real bus/device/function information as configured by the BIOS,
so use that for a better number.
Carolyn adds additional text description for the base pf0 and flow
director generated interrupts, since these interrupts are difficult
to distinguish per port on a multi-function device.
Jacob resolves an issue related to images with multiple PFs per
physical port. We cannot fully support 1588 PTP features, since only
one port should control (i.e. write) the registers at a time. Doing
so can cause interference of functionality.
Anjali provides several updates to i40e, first adds the Virtual Channel
OP event opcode for CONFIG_RSS, so that the Virtual Channel state
machine can properly decipher status change events. Then updates the
driver to add (and use) i40e_is_vf macro for future expansion when new
VF MAC types get added. Adds new update VSI flow to accommodate a
firmware dix with VSI loopback mode. All VSIs on a VEB should either
have loopback enabled or disabled, a mixed mode is not supported for a
VEB. Since our driver supports multiple VSIs per PF that need to talk to
each other make sure to enable Loopback for the PF and FDIR VSI as well.
Mitch provides a couple of i40e and i40evf patches. First updates
i40evf init code more adept at handling when multiple VFs attempt
to initialize simultaneously.
Joe Perches provides a i40e patch which resolves a compile warning
about about frame size being larger than 2048 bytes by reducing the
stack use by using kmemdup and not using a very large struct on the
stack.
v2:
- Dropped patch 13 & 14 while Mitch reworks the patches based on
feedback from Ben Hutchings, probably the tryptophan in the turkey
is to blame for the delay...

This patch adds two new helper functions skb_put_padto and eth_skb_pad.
These functions deviate from the standard skb_pad or skb_padto in that they
will also update the length and tail pointers so that they reflect the
padding added to the frame.
The eth_skb_pad helper is meant to be used with Ethernet devices to update
either Rx or Tx frames so that they report the correct size. The
skb_put_padto helper is meant to be used primarily in the transmit path for
network devices that need frames to be padded up to some minimum size and
don't wish to simply update the length somewhere external to the frame.
The motivation behind this is that there are a number of implementations
throughout the network device drivers that are all doing the same thing,
but each a little bit differently and as a result several implementations
contain bugs such as updating the length without updating the tail offset
and other similar issues.
