Pull KVM updates from Paolo Bonzini:
"Fixes and features for 3.18.
Apart from the usual cleanups, here is the summary of new features:
- s390 moves closer towards host large page support
- PowerPC has improved support for debugging (both inside the guest
and via gdbstub) and support for e6500 processors
- ARM/ARM64 support read-only memory (which is necessary to put
firmware in emulated NOR flash)
- x86 has the usual emulator fixes and nested virtualization
improvements (including improved Windows support on Intel and
Jailhouse hypervisor support on AMD), adaptive PLE which helps
overcommitting of huge guests. Also included are some patches that
make KVM more friendly to memory hot-unplug, and fixes for rare
caching bugs.
Two patches have trivial mm/ parts that were acked by Rik and Andrew.
Note: I will soon switch to a subkey for signing purposes"

Commit 7bced397510a ("net_dma: simple removal") removed the long-dead
net_dma code, but unintentionally broke the build for the qualcomm
crypto engine (qce) that had accidentally depended on the inclusion of
<linux/dmaengine.h> through the networking header files that used to
have it.
Add the required dmaengine.h include explicitly to fix the breakage.

This is the core of the cxl driver.
It adds support for using cxl cards in the powernv environment only (ie POWER8
bare metal). It allows access to cxl accelerators by userspace using the
/dev/cxl/afuM.N char devices.
The kernel driver has no knowledge of the function implemented by the
accelerator. It provides services to userspace via the /dev/cxl/afuM.N
devices. When a program opens this device and runs the start work IOCTL, the
accelerator will have coherent access to that processes memory using the same
virtual addresses. That process may mmap the device to access any MMIO space
the accelerator provides. Also, reads on the device will allow interrupts to
be received. These services are further documented in a later patch in
Documentation/powerpc/cxl.txt.
Documentation of the cxl hardware architecture and userspace API is provided in
subsequent patches.

This adds the base cxl support that cannot be built as a module. Specifically
it adds the cxl callbacks that are called from the core powerpc mm code which
must always exist irrespective of if the cxl module is loaded or not. This is
similar to how cell works with CONFIG_SPU_BASE.
This adds a cxl_slbia() call (similar to spu_flush_all_slbs()) which checks if
the cxl module is loaded and in use, returning immediately if it is not. If it
is in use it calls into the cxl SLB invalidation code.

"Even though this has fixes marked for -stable, given the size and the

These patches have been languishing in my tree for a long while. The
fact that I do not have the time to do proper/prompt maintenance of
this tree is a primary factor in the decision to step down as
dmaengine maintainer. That and the fact that the bulk of drivers/dma/
activity is going through Vinod these days.

conflicts against mainline and net-next (for-3.18).

The Broadcom OSB4 IDE Controller (vendor and device IDs: 1166:0211)
does not support 64-KB DMA transfers.
Whenever a 64-KB DMA transfer is attempted,
the transfer fails and messages similar to the following
are written to the console log:

lspci shows that the driver used for the Broadcom OSB4 IDE Controller is
pata_serverworks:
00:0f.1 IDE interface: Broadcom OSB4 IDE Controller (prog-if 8e [Master SecP SecO PriP])
Flags: bus master, medium devsel, latency 64

Kernel driver in use: pata_serverworks
The pata_serverworks driver supports five distinct device IDs,
one being the OSB4 and the other four belonging to the CSB series.
The CSB series appears to support 64-KB DMA transfers,
as tests on a machine with an SAI2 motherboard
containing a Broadcom CSB5 IDE Controller (vendor and device IDs: 1166:0212)
showed no problems with 64-KB DMA transfers.
This problem was first discovered when attempting to install openSUSE
from a DVD on a machine with an STL2 motherboard.
Using the pata_serverworks module,
older releases of openSUSE will not install at all due to the timeouts.
Releases of openSUSE prior to 11.3 can be installed by disabling
the pata_serverworks module using the brokenmodules boot parameter,
which causes the serverworks module to be used instead.
Recent releases of openSUSE (12.2 and later) include better error recovery and
will install, though very slowly.
On all openSUSE releases, the problem can be recreated
on a machine containing a Broadcom OSB4 IDE Controller
by mounting an install DVD and running a command similar to the following:
find /mnt -type f -print | xargs cat > /dev/null
The patch below corrects the problem.
Similar to the other ATA drivers that do not support 64-KB DMA transfers,
the patch changes the ata_port_operations qc_prep vector to point to a routine
that breaks any 64-KB segment into two 32-KB segments and
changes the scsi_host_template sg_tablesize element to reduce by half
the number of scatter/gather elements allowed.
These two changes affect only the OSB4.

lib/glob.c provides a new glob_match() function, with arguments in
(pattern, string) order. It replaced a private function with arguments
in (string, pattern) order, but I didn't swap the call site...
The result was the entire ATA blacklist was effectively disabled.
The lesson for today is "I f***ed up *how* badly *how* many months ago?",
er, I mean "Nobody Tests RC Kernels On Legacy Hardware".
This was not a subtle break, but it made it through an entire RC
cycle unreported, presumably because all the people doing testing
have full-featured hardware.
(FWIW, the reason for the argument swap was because fnmatch() does it that
way, and for a while implementing a full fnmatch() was being considered.)

When a channel context is removed, the hw_queue_base
is set to -1, this will result in a panic because
ath9k_chanctx_stop_queues() can be called on an interface
that is not assigned to any context yet - for example,
when trying to scan.
Fix this issue by setting the hw_queue_base to zero
when a channel context is removed.

Currently the allowed "respose rate" set (rates for HW generated frames
like ACKs) is the same as the basic rate set.
The HW will use the higher allowed response rate that is lower than the
rate of the received frame.
This is more or less what IEEE80211 mandates, but I missed the fact
that IEEE80211 also says that whenever it happens that for a modulation
class there is no any rate in the basic rates set, then the response rate
set shall include also all the mandatory rates for that modulation class.
This patch adds mandatory OFDM rates to the allowed response rate set if
no OFDM rate is included in the basic rate set.
Depending by the AP, I faced cases in which this patch seems to cause a
noticeable perfomance improvement.
- With my usual test AP there is no particular perfomance difference.
- With a prism54/hostapd AP this patch causes RX thoughput increase from
about 5Mbps to about 20Mbps.
Hopefully this patch may help people that faced performance regression wrt
the old staging driver.

This patch fixes a bug on hotmod removing.
After ipmi interface is removed using hotmod, kernel panic occurs when
rmmod impi_si. For example, try this:
# echo "remove,"`cat /proc/ipmi/0/params` > \
/sys/module/ipmi_si/parameters/hotmod
# rmmod ipmi_si
Then, rmmod fails with the following messages.
------------[ cut here ]------------

list_del in cleanup_one_si() fails because the smi_info is already
removed when hotmod removing.
When ipmi interface is removed by hotmod, smi_info is removed by
cleanup_one_si(), but is is still set in drvdata. Therefore when rmmod
ipmi_si, ipmi_pnp_remove tries to remove it again and fails.
By this patch, a pointer to smi_info in drvdata is cleared when hotmod
removing so that it will be not accessed when rmmod.

Building ipmi on arm with gcc-4.9 results in this warning for an
allmodconfig build:
drivers/char/ipmi/ipmi_si_intf.c: In function 'ipmi_thread':
include/linux/time.h:28:5: warning: 'busy_until.tv_sec' may be used uninitialized in this function [-Wmaybe-uninitialized]

^
drivers/char/ipmi/ipmi_si_intf.c:1007:18: note: 'busy_until.tv_sec' was declared here
struct timespec busy_until;
^
The warning is bogus and this case can not occur. Apparently this is a
false positive resulting from gcc getting a little smarter about
tracking assignments but not smart enough.
Marking the ipmi_thread_busy_wait function as inline gives the gcc
optimization logic enough information to figure out for itself that the
case cannot happen, which gets rid of the warning without adding any
fake initialization.

Testing xmit_more support with netperf and connected UDP sockets,
I found strange dst refcount false sharing.
Current handling of IFF_XMIT_DST_RELEASE is not optimal.
Dropping dst in validate_xmit_skb() is certainly too late in case
packet was queued by cpu X but dequeued by cpu Y
The logical point to take care of drop/force is in __dev_queue_xmit()
before even taking qdisc lock.
As Julian Anastasov pointed out, need for skb_dst() might come from some
packet schedulers or classifiers.
This patch adds new helper to cleanly express needs of various drivers
or qdiscs/classifiers.
Drivers that need skb_dst() in their ndo_start_xmit() should call
following helper in their setup instead of the prior :
dev->priv_flags &= ~IFF_XMIT_DST_RELEASE;
->
netif_keep_dst(dev);
Instead of using a single bit, we use two bits, one being
eventually rebuilt in bonding/team drivers.
The other one, is permanent and blocks IFF_XMIT_DST_RELEASE being
rebuilt in bonding/team. Eventually, we could add something
smarter later.

Drivers should avoid NETDEV_TX_BUSY as much as possible.
They should stop the tx queue before qdisc even tries to push another
packet, to avoid requeues.
For a driver supporting skb->xmit_more, this is likely to be a prereq
anyway, otherwise we could have a tx deadlock : We need to force a
doorbell if TX ring is full.

# 3c59x: Add dma error checking and recovery

However, the #else part (of the #if DO_ZEROCOPY test) is changed this way:

When Tx VLAN offloading is disabled frames with size ~ MTU are not
transmitted as the driver does not account 4 bytes of VLAN header added
by stack. It should use VLAN_ETH_HLEN instead of ETH_HLEN.
The second problem is with newer BNA chips (BNA 1860). These chips filter
out any VLAN tagged frames in Tx path. This is a problem when Tx VLAN
offloading is disabled and frames are tagged by stack. Older chips like
1010/1020 are not affected as they probably don't do such filtering.
