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.

Commit 6bd4a5d96c changed the
ANDROID_ALARM_GET_TIME ioctls from IOW to IOR. While technically
correct, the _IOC_DIR bits are ignored by alarm_ioctl, so the
commit breaks a userspace ABI used by all existing Android devices
for a purely cosmetic reason. Revert it.

The check whether the IBSS is active and can be removed should be
performed before deinitializing the fields used for the check/search.
Otherwise, the configured BSS will not be found and removed properly.
To make it more clear for the future, rename sdata->u.ibss to the
local pointer ifibss which is used within the checks.

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.

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.

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.

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.

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.

access_ok() returns always "true" on s390. Therefore all access_ok()
invocations are rather pointless.
However when walking page tables we need to make sure that everything
is within bounds of the ASCE limit of the task's address space.

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.

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.

Any failures in intel_sdvo_init() after the intel_sdvo_setup_output() call
left behind ghost connectors, attached (with a dangling pointer) to the
sdvo that has been cleaned up and freed. Properly destroy any connectors
attached to the encoder.

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.

The current topology code confuses core id vs physical package id.
In other words /sys/devices/system/cpu/cpuX/topology/core_id
displays the physical_package_id (aka socket id) instead of the
core id.
The physical_package_id sysfs attribute always displays "-1"
instead of the socket id.
Fix this mix-up with a small patch which defines and initializes
topology_physical_package_id correctly and fixes the broken
core id handling.

If user space is running in primary mode it can switch to secondary
or access register mode, this is used e.g. in the clock_gettime code
of the vdso. If a signal is delivered to the user space process while
it has been running in access register mode the signal handler is
executed in access register mode as well which will result in a crash
most of the time.
Set the address space control bits in the PSW to the default for the
execution of the signal handler and make sure that the previous
address space control is restored on signal return. Take care
that user space can not switch to the kernel address space by
modifying the registers in the signal frame.

In patch "HID: microsoft: fix invalid rdesc for 3k kbd" I fixed
support for MS 3k keyboards. However the added check using memcmp and
a compound statement breaks build on architectures where memcmp is a
macro with parameters.
hid-microsoft.c:51:18: error: macro "memcmp" passed 6 arguments, but takes just 3
On x86_64, memcmp is a function, so I did not see the error.
