"NFC: 3.16: First pull request
This is the NFC pull request for 3.16. We have:
- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
thus relies on the HCI stack. This submission provides support for tag
redaer/writer mode (including Type 5) and device tree bindings.
- PM runtime support and a bunch of bug fixes for TI's trf7970a.
- Device tree support for NXP's pn544. Legacy platform data support is
obviously kept intact.
- NFC Tag type 4B support to the NFC Digital stack.
- SOCK_RAW type support to the raw NFC socket, and allow NCI
sniffing from that. This can be extended to report HCI frames and also
proprietarry ones like e.g. the pn533 ones."

We want slightly different behavior from them:
- On single queue devices, we currently use the per-process plug
for deferred IO and for merging.
- On multi queue devices, we don't use the per-process plug, but
we want to go straight to hardware for SYNC IO.
Split blk_mq_make_request() into a blk_sq_make_request() for single
queue devices, and retain blk_mq_make_request() for multi queue
devices. Then we don't need multiple checks for q->nr_hw_queues
in the request mapping.

====================
Netfilter/nftables updates for net-next
The following patchset contains Netfilter/nftables updates for net-next,
most relevantly they are:
1) Add set element update notification via netlink, from Arturo Borrero.
2) Put all object updates in one single message batch that is sent to
kernel-space. Before this patch only rules where included in the batch.
This series also introduces the generic transaction infrastructure so
updates to all objects (tables, chains, rules and sets) are applied in
an all-or-nothing fashion, these series from me.
3) Defer release of objects via call_rcu to reduce the time required to
commit changes. The assumption is that all objects are destroyed in
reverse order to ensure that dependencies betweem them are fulfilled
(ie. rules and sets are destroyed first, then chains, and finally
tables).
4) Allow to match by bridge port name, from Tomasz Bursztyka. This series
include two patches to prepare this new feature.
5) Implement the proper set selection based on the characteristics of the
data. The new infrastructure also allows you to specify your preferences
in terms of memory and computational complexity so the underlying set
type is also selected according to your needs, from Patrick McHardy.
6) Several cleanup patches for nft expressions, including one minor possible
compilation breakage due to missing mark support, also from Patrick.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to i40e and i40evf.
Shannon makes minor changes to the AdminQ interface to bring it up to
date. Removes the hard coding of stats struct size in ethtool, in prep
for adding data fields which are configuration dependent.
Catherine removes some unused and unneeded PCI bus defines.
Jesse fixes the copyright headers and finishes up the removal of the PTP
Tx work functionality which allows us to rely on the Tx timesync interrupt.
Mitch provides a number of fixes and cleanups for i40e/i40evf based on
suggestions from Ben Hutchings. First is to use a macro parameter for
ethtool stats instead of just assuming that a valid netdev variable
exists. Second is not to tell ethtool that the VF can do 10GbaseT, when
it really has no idea what its link speed is, so set the supported value
to 0 instead. Make the ethtool_ops structure constant since it is
extremely unlikely to change at runtime. Ethtool consistently reports
0 values for our ITR settings because we never actually use them, so
fix this by setting the default values to the specified default values.
Greg avoids a compile error by wrapping the call to i40e_alloc_vfs() in
CONFIG_PCI_IOV because the function itself is wrapped in the same
conditional compile block.
Alexander Gordeev updates the driver to use the new pci_enable_msi_range()
and pci_enable_msix_range() or pci_enable_msi_exact() and
pci_enable_msix_exact().
Jean Sacren provides a fix where the wrong error code was being passed to
i40e_open().

Experience with the recent e114a710aa50 ("tcp: fix cwnd limited
checking to improve congestion control") has shown that there are
common cases where that commit can cause cwnd to be much larger than
necessary. This leads to TSO autosizing cooking skbs that are too
large, among other things.
The main problems seemed to be:
(1) That commit attempted to predict the future behavior of the
connection by looking at the write queue (if TSO or TSQ limit
sending). That prediction sometimes overestimated future outstanding
packets.
(2) That commit always allowed cwnd to grow to twice the number of
outstanding packets (even in congestion avoidance, where this is not
needed).
This commit improves both of these, by:
(1) Switching to a measurement-based approach where we explicitly
track the largest number of packets in flight during the past window
("max_packets_out"), and remember whether we were cwnd-limited at the
moment we finished sending that flight.
(2) Only allowing cwnd to grow to twice the number of outstanding
packets ("max_packets_out") in slow start. In congestion avoidance
mode we now only allow cwnd to grow if it was fully utilized.

CS.RPL is not equal to the CPL in the few instructions between
setting CR0.PE and reloading CS. And CS.DPL is also not equal
to the CPL for conforming code segments.
However, SS.DPL *is* always equal to the CPL except for the weird
case of SYSRET on AMD processors, which sets SS.DPL=SS.RPL from the
value in the STAR MSR, but force CPL=3 (Intel instead forces
SS.DPL=SS.RPL=CPL=3).
So this patch:
- modifies SVM to update the CPL from SS.DPL rather than CS.RPL;
the above case with SYSRET is not broken further, and the way
to fix it would be to pass the CPL to userspace and back
- modifies VMX to always return the CPL from SS.DPL (except
forcing it to 0 if we are emulating real mode via vm86 mode;
in vm86 mode all DPLs have to be 3, but real mode does allow
privileged instructions). It also removes the CPL cache,
which becomes a duplicate of the SS access rights cache.
This fixes doing KVM_IOCTL_SET_SREGS exactly after setting
CR0.PE=1 but before CS has been reloaded.

I noticed on some of my systems that page fault tracing doesn't
work:
cd /sys/kernel/debug/tracing
echo 1 > events/exceptions/enable
cat trace;
# nothing shows up
I eventually traced it down to CONFIG_KVM_GUEST. At least in a
KVM VM, enabling that option breaks page fault tracing, and
disabling fixes it. I tried on some old kernels and this does
not appear to be a regression: it never worked.
There are two page-fault entry functions today. One when tracing
is on and another when it is off. The KVM code calls do_page_fault()
directly instead of calling the traced version:
> dotraplinkage void __kprobes
> do_async_page_fault(struct pt_regs *regs, unsigned long
> error_code)
> {
> enum ctx_state prev_state;
>
> switch (kvm_read_and_reset_pf_reason()) {
> default:
> do_page_fault(regs, error_code);
> break;
> case KVM_PV_REASON_PAGE_NOT_PRESENT:
I'm also having problems with the page fault tracing on bare
metal (same symptom of no trace output). I'm unsure if it's
related.
Steven had an alternative to this which has zero overhead when
tracing is off where this includes the standard noops even when
tracing is disabled. I'm unconvinced that the extra complexity
of his apporach:
http://lkml.kernel.org/r/20140508194508.561ed220@gandalf.local.home
is worth it, expecially considering that the KVM code is already
making page fault entry slower here. This solution is
dirt-simple.

During task switch, all of CS.DPL, CS.RPL, SS.DPL must match (in addition
to all the other requirements) and will be the new CPL. So far this
worked by carefully setting the CS selector and flag before doing the
task switch; setting CS.selector will already change the CPL.
However, this will not work once we get the CPL from SS.DPL, because
then you will have to set the full segment descriptor cache to change
the CPL. ctxt->ops->cpl(ctxt) will then return the old CPL during the
task switch, and the check that SS.DPL == CPL will fail.
Temporarily assume that the CPL comes from CS.RPL during task switch
to a protected-mode task. This is the same approach used in QEMU's
emulation code, which (until version 2.0) manually tracks the CPL.
