sata_sis: missing PM support
ahci: add PCI ID for Marvell 88SE9170 SATA controller
Helge Deller noted a few weeks ago problems with the AIO support on
parisc. This change is the result of numerous iterations on how best to
deal with this problem.
The solution adopted here is to provide full cache coherency in a
uniform manner on all parisc systems. This involves calling
flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on
kunmap operations. As a result, the copy_user_page() and
clear_user_page() functions can be removed and the overall code is
simpler.
The change ensures that both userspace and kernel aliases to a mapped
page are invalidated and flushed. This is necessary for the correct
operation of PA8800 and PA8900 based systems which do not support
inequivalent aliases.
With this change, I have observed no cache related issues on c8000 and
rp3440. It is now possible for example to do kernel builds with "-j64"
on four way systems.
On systems using XFS file systems, the patch recently posted by Mikulas
Patocka to "fix crash using XFS on loopback" is needed to avoid a hang
caused by an uninitialized lock passed to flush_dcache_page() in the
page struct.

Commit 6d9252bd9a4bb (clk: Add support for power of two type dividers)
merged in v3.6 added the _get_val function to convert a divisor value to
a register field value depending on the flags. However it used the type
u8 for the div field, causing divisors larger than 255 to be masked
and the resultant clock rate to be too high.
E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down
to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This
was masked to 238 (0xee) resulting in a frequency of 103.26KHz.

The only BIOS on record that needs the 14 offset has a bios major
version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18
offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the
bios major version, look at the BMP version. BIOSes with BMP version 0
do not contain a detectable script, so always return 0 for them.

Jani has been a really active bug-scrubber in the past few months.
I've asked him whether he wants to do this in a more official capacity
and he agreed. I've already chatted with Dave and Jesse and they
support this.
Note that everyone can't now just relax because "Jani will do all the
bug scrubbing" - au contraire expect more nagging and poking now that
we have more bandwidth.
Longer-term the plan is to share more of the maintainer duties, but we
need to fix up the infrastructure a bit first (like moving the git
repo to a common location).
While at it also add the newly set-up patchwork instance.

br_multicast_set_hash_max() is called from process context in
net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function.
br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock),
which can deadlock the CPU if a softirq that also tries to take the
same lock interrupts br_multicast_set_hash_max() while the lock is
held . This can happen quite easily when any of the bridge multicast
timers expire, which try to take the same lock.
The fix here is to use spin_lock_bh(), preventing other softirqs from
executing on this CPU.
Steps to reproduce:
1. Create a bridge with several interfaces (I used 4).
2. Set the "multicast query interval" to a low number, like 2.
3. Enable the bridge as a multicast querier.
4. Repeatedly set the bridge hash_max parameter via sysfs.
# brctl addbr br0
# brctl addif br0 eth1 eth2 eth3 eth4
# brctl setmcqi br0 2
# brctl setmcquerier br0 1

The existing serial state notification handling expected older Option
devices, having a hardcoded assumption that the Modem port was always
USB interface #2. That isn't true for devices from the past few years.
hso_serial_state_notification is a local cache of a USB Communications
Interface Class SERIAL_STATE notification from the device, and the
USB CDC specification (section 6.3, table 67 "Class-Specific Notifications")
defines wIndex as the USB interface the event applies to. For hso
devices this will always be the Modem port, as the Modem port is the
only port which is set up to receive them by the driver.
So instead of always expecting USB interface #2, instead validate the
notification with the actual USB interface number of the Modem port.

Commit f5a44db5d2 introduced a regression on filesystems created with
the bigalloc feature (cluster size > blocksize). It causes xfstests
generic/006 and /013 to fail with an unexpected JBD2 failure and
transaction abort that leaves the test file system in a read only state.
Other xfstests run on bigalloc file systems are likely to fail as well.
The cause is the accidental use of a cluster mask where a cluster
offset was needed in ext4_ext_map_blocks().

be2net: disable RSS when number of RXQs is reduced to 1 via
set-channels

The driver wrongly assumes 16 EQs/vectors are available for each BE3 PF.
When SR-IOV is enabled, a BE3 PF can support only a max of 8 EQs.

The loopback test FW cmd may need upto 15 seconds to complete on
certain PHYs. This patch also fixes the name of the completion variable
used to synchronize FW cmd completions as it not used by the flashing
cmd alone anymore.

When *only* the default RXQ is used, the RSS policy must be disabled so
that all IP and no-IP traffic is placed into the default RXQ. If not,
IP traffic is dropped.
Also, issue the RSS_CONFIG cmd only if FW advertises RSS capability for
the interface.

In function lowpan_header_create(), we invoke the following code
construct:
struct ipv6hdr *hdr;
...
hdr = ipv6_hdr(skb);
...
if (...)
memcpy(hc06_ptr + 1, &hdr->flow_lbl[1], 2);
else
memcpy(hc06_ptr, &hdr, 4);
Where the else path of the condition, that is, non-compression
path, calls memcpy() with a pointer to struct ipv6hdr *hdr as
source, thus two levels of indirection. This cannot be correct,
and likely only one level of pointer was intended as source
buffer for memcpy() here.

If the hypervisor configures a vlan for the VF via the PF, the expected
result is that only packets tagged by said vlan will be received by the VF
(and that vlan will be silently removed).
Due to an incorrect manipulation of vlan filters in the driver, the
VF can receive untagged traffic even if the hypervisor configured
some vlan for it.
This patch corrects the behaviour.

There are 2 different (related) flows in the slowpath configuration
that utilize the same pointer and cast it to different structs;
This is obviously incorrect as the intended allocated memory is that
of the smaller struct, possibly causing the flow utilizing the larger
struct to corrupt other slowpath configuration.
Since both flows are exclusive, set the allocated memory to be a union
of both structs.

When a PF receives a VF message indicating a change in RSS properties
it should clean the flags' bit-fields; Otherwise, it's possible that
some random values will be considered as flags by the lower layers configuring
the RSS in FW.

Number of VFs in PCIe configuration space is zero-based. Driver incorrectly
sets the number of VFs to be larger by one than what actually is feasible by
HW, which might cause later VFs to fail to allocate their MSI-X interrupts.

Pull ARM fixes from Russell King:
"Another set of small fixes for ARM, covering various areas.
Laura fixed a long standing issue with virt_addr_valid() failing to
handle holes in memory. Steve found a problem with dcache flushing
for compound pages. I fixed another bug in footbridge stuff causing
time to tick slowly, and also a problem with the AES code which can
cause linker errors.
A patch from Rob which fixes Xen problems induced by a lack of
consistency in our naming of ioremap_cache() - which thankfully has
very few users"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
