Martin K. Petersen 5db44863b6 [SCSI] sd: Implement support for WRITE SAME
Implement support for WRITE SAME(10) and WRITE SAME(16) in the SCSI disk
driver.

 - We set the default maximum to 0xFFFF because there are several
   devices out there that only support two-byte block counts even with
   WRITE SAME(16). We only enable transfers bigger than 0xFFFF if the
   device explicitly reports MAXIMUM WRITE SAME LENGTH in the BLOCK
   LIMITS VPD.

 - max_write_same_blocks can be overriden per-device basis in sysfs.

 - The UNMAP discovery heuristics remain unchanged but the discard
   limits are tweaked to match the "real" WRITE SAME commands.

 - In the error handling logic we now distinguish between WRITE SAME
   with and without UNMAP set.

The discovery process heuristics are:

 - If the device reports a SCSI level of SPC-3 or greater we'll issue
   READ SUPPORTED OPERATION CODES to find out whether WRITE SAME(16) is
   supported. If that's the case we will use it.

 - If the device supports the block limits VPD and reports a MAXIMUM
   WRITE SAME LENGTH bigger than 0xFFFF we will use WRITE SAME(16).

 - Otherwise we will use WRITE SAME(10) unless the target LBA is beyond
   0xFFFFFFFF or the block count exceeds 0xFFFF.

 - no_write_same is set for ATA, FireWire and USB.

Martin K. Petersen 3c6bdaeab4 [SCSI] Add a report opcode helper
The REPORT SUPPORTED OPERATION CODES command can be used to query
whether a given opcode is supported by a device. Add a helper function
that allows us to look up commands.

We only issue RSOC if the device reports compliance with SPC-3 or
later. But to err on the side of caution we disable the command for ATA,
FireWire and USB.

Alexander Duyck 1ba56fb45a vxlan: Update hard_header_len based on lowerdev when instantiating VXLAN
In the event of a VXLAN device being linked to a device that has a
hard_header_len greater than that of standard ethernet we could end up with
the hard_header_len not being large enough for outgoing frames.  In order to
prevent this we should update the length when a lowerdev is provided.

Jean Delvare d85c8a6ab2 MAINTAINERS: i2c: 7 years, this is it
I have been maintaining the i2c subsystem for 7 years now, it's about
time to let someone else take over. Just before I leave, I would like
to thank several individuals who made this possible at all:

* Greg Kroah-Hartman, for his faith in my potential subsystem
  maintainer skills. Greg, I hope I met your expectations.
* Late David Brownell, for helping me convert the i2c subsystem to the
  standard device driver model. Rest in peace David, we're missing you.
* Ben Dooks, for stepping in when I asked for someone to take care of
  the huge flow of new i2c adapter drivers for embedded systems.
* Wolfram Sang, for joining the crew when it became clear that there
  was more review work than Ben and myself could deal with.

I hope I did not forget anyone, please forgive me if I did.

Another big thank is due to Wolfram again, who quickly proposed to
take over as the main i2c subsystem maintainer. This will allow for a
smooth and fast transition.

Note that I will keep maintaining all I2C/SMBus controller drivers for
PC systems as well as a few others. I am hereby updating MAINTAINERS
accordingly. I'll also keep maintaining user-space i2c-tools.

Alexander Duyck 52b702ffa5 vxlan: Fix error that was resulting in VXLAN MTU size being 10 bytes too large
This change fixes an issue I found where VXLAN frames were fragmented when
they were up to the VXLAN MTU size.  I root caused the issue to the fact that
the headroom was 4 + 20 + 8 + 8.  This math doesn't appear to be correct
because we are not inserting a VLAN header, but instead a 2nd Ethernet header.
As such the math for the overhead should be 20 + 8 + 8 + 14 to account for the
extra headers that are inserted for VXLAN.

Eric Dumazet bd090dfc63 tcp: tcp_replace_ts_recent() should not be called from tcp_validate_incoming()
We added support for RFC 5961 in latest kernels but TCP fails
to perform exhaustive check of ACK sequence.

We can update our view of peer tsval from a frame that is
later discarded by tcp_ack()

This makes timestamps enabled sessions vulnerable to injection of
a high tsval : peers start an ACK storm, since the victim
sends a dupack each time it receives an ACK from the other peer.

As tcp_validate_incoming() is called before tcp_ack(), we should
not peform tcp_replace_ts_recent() from it, and let callers do it
at the right time.

Bjørn Mork bbc8d9228e net: cdc_ncm: add Huawei devices
A number of Huawei 3G and LTE modems implement a CDC NCM function,
including the necessary functional descriptors, but using a non
standard interface layout and class/subclass/protocol codes.

These devices can be handled by this driver with only a minor
change to the probing logic, allowing a single combined control
and data interface.  This works because the devices
- include a CDC Union descriptor labelling the combined
  interface as both master and slave, and
- have an alternate setting #1 for the bulk endpoints on the
  combined interface.

The 3G/LTE network connection is managed by vendor specific AT
commands on a serial function in the same composite device.
Handling the managment function is out of the scope of this
driver.  It will be handled by an appropriate USB serial
driver.

Ursula Braun 7702745b15 qeth: set new mac even if old mac is gone
If the set_mac_address() function of qeth is invoked, qeth deletes
the old mac address first on OSA. Only if deletion returns
successfully the new mac address is set on OSA. Deletion may return
with a return value "MAC not found on OSA". In this case qeth
should continue setting the new mac address.

When the OSA cable is pulled, OSA forgets any set mac address. If
the OSA network interface acts as a slave to a bonding master
interface, bonding can invoke the set_mac_address function for
failover purposes and depends on successful setting of the new mac
address even though the old mac address could no longer be deleted.

Heiko Carstens 4bffbb3455 s390/mm: have 16 byte aligned struct pages
Select HAVE_ALIGNED_STRUCT_PAGE on s390, so that the slub allocator can make
use of compare and swap double for lockless updates. This increases the size
of struct page to 64 bytes (instead of 56 bytes), however the performance gain
justifies the increased size:

- now excactly four struct pages fit into a single cache line; the
  case that accessing a struct page causes two cache line loads
  does not exist anymore.
- calculating the offset of a struct page within the memmap array
  is only a simple shift instead of a more expensive multiplication.

QEMU first retrieves the supported features via KVM_GET_SUPPORTED_CPUID
and then sets them later. So guest's X86_FEATURE_XSAVE should be masked
out on hosts without X86_FEATURE_XSAVE, making kvm_set_cr4 with
X86_CR4_OSXSAVE fail. Userspaces that allow specifying guest cpuid with
X86_FEATURE_XSAVE even on hosts that do not support it, might be
susceptible to this attack from inside the guest as well.

Allow setting X86_CR4_OSXSAVE bit only if host has XSAVE support.

Fabio Estevam 2d4d07b97c ARM: boot: Fix usage of kecho
Since commit edc88ceb0 (ARM: be really quiet when building with 'make -s') the
following output is generated when building a kernel for ARM:

echo '  Kernel: arch/arm/boot/Image is ready'
  Kernel: arch/arm/boot/Image is ready
  Building modules, stage 2.
echo '  Kernel: arch/arm/boot/zImage is ready'
  Kernel: arch/arm/boot/zImage is ready

As per Documentation/kbuild/makefiles.txt the correct way of using kecho is
'@$(kecho)'.

Make this change so no more unwanted 'echo' messages are displayed.

Kevin Hilman 1ef43369c6 ARM: OMAP4: TWL: mux sys_drm_msecure as output for PMIC
On OMAP4 boards using the TWL6030 PMIC, the sys_drm_msecure is
connected to the MSECURE input of the TWL6030 PMIC.  This signal
controls the secure-mode operation of the PMIC.  If its not mux'd
correctly, some functionality of the PMIC will not be accessible since
the PMIC will be in secure mode.

For example, if the TWL RTC is in secure mode, most of its registers
are read-only, meaning (re)programming the RTC (e.g. for wakeup from
suspend) will fail.

To fix, ensure the signal is properly mux'd as output when TWL is
intialized.

This fix is required when using recent versions of u-boot (>= v2012.04.01)
since u-boot is no longer setting the default mux for this pin.

Arnd Bergmann 69178dfeb1 This series fixes an annoying regression to make MUSB working
on omap4 again. Although it's getting rather late for these
 changes for the -rc cycle, it is important as many devices
 are using MUSB for charging and connectivity.
 
 With the USB PHY changes, MUSB started using the newly added
 drivers/usb/phy/omap-usb2.c driver introduced by commit
 657b306a (usb: phy: add a new driver for omap usb2 phy)
 that is using the newly introduced drivers/bus/omap-ocp2scp.c
 introduced by commit 26a84b3e (drivers: bus: add a new driver
 for omap-ocp2scp).
 
 These changes allowed dropping a lot of PHY related code from
 arch/arm/mach-omap2/omap_phy_internal.c and have it live in
 the device driver like it should with commit c9e4412a (arm: omap:
 phy: remove unused functions from omap-phy-internal.c).
 
 However, MUSB on omap4 broke with these changes for legacy
 platform data boot, and now only works with device tree for
 omap4. Unfortunately we are still few critical bindings away
 from being able to make omap4 usbale with device tree.
 
 Fix the regression properly by adding platform data support
 to the ocp2scp driver so we can avoid adding back the driver
 code to arch/arm/mach-omap2.
