A collection of fixes for ARM platforms. A little large due to us missing to
do one last week, but there's nothing in particular here that is in itself
large and scary.
Mostly a handful of smaller fixes all over the place. The majority is made
up of fixes for OMAP, but there are a few for others as well. In particular,
there was a decision to rename a binding for the Broadcom pinctrl block that
we need to go in before the final release since we then treat it as ABI.

staging/cxt1e1/linux.c: Correct arbitrary memory write in c4_ioctl()
This fixes CVE-2014-0102.
The following command sequence produces an oops:
keyctl new_session
i=`keyctl newring _ses @s`
keyctl link @s $i
The problem is that search_nested_keyrings() sees two keyrings that have
matching type and description, so keyring_compare_object() returns true.
s_n_k() then passes the key to the iterator function -
keyring_detect_cycle_iterator() - which *should* check to see whether this is
the keyring of interest, not just one with the same name.
Because assoc_array_find() will return one and only one match, I assumed that
the iterator function would only see an exact match or never be called - but
the iterator isn't only called from assoc_array_find()...
The oops looks something like this:
kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
invalid opcode: 0000 [#1] SMP
...
RIP: keyring_detect_cycle_iterator+0xe/0x1f
...
Call Trace:
search_nested_keyrings+0x76/0x2aa
__key_link_check_live_key+0x50/0x5f
key_link+0x4e/0x85
keyctl_keyring_link+0x60/0x81
SyS_keyctl+0x65/0xe4
tracesys+0xdd/0xe2
The fix is to make keyring_detect_cycle_iterator() check that the key it
has is the key it was actually looking for rather than calling BUG_ON().
A testcase has been included in the keyutils testsuite for this:

Ether_addr_equal_64bits is more efficient than ether_addr_equal, and
can be used when each argument is an array within a structure that
contains at least two bytes of data beyond the array, so it is safe
to use it for vlan, and make sense for fast path.

According Joe's suggestion, maybe it'd be faster to add an unlikely to
the test for PCKET_OTHERHOST, so I add it and see whether the performance
could be better, although the differences is so small and negligible, but
it is hard to catch that any lower device would set the skb type to
PACKET_OTHERHOST, so most of time, I think it make sense to add unlikely
for the test.

The pci shutdown handler added in:
bnx2: Add pci shutdown handler
commit 25bfb1dd4b
created a shutdown down sequence without chip reset if the device was
never brought up. This can cause the firmware to shutdown the PHY
prematurely and cause MMIO read cycles to be unresponsive. On some
systems, it may generate NMI in the bnx2's pci shutdown handler.
The fix is to tell the firmware not to shutdown the PHY if there was
no prior chip reset.

Pull thermal fixes from Zhang Rui:
"Specifics:
- Update the help text of INT3403 Thermal driver, which was not
friendly to users. From Zhang Rui.
- The "type" sysfs attribute of x86_pkg_temp_thermal registered
thermal zones includes an instance number, which makes the
thermal-to-hwmon bridge fails to group them all in a single hwmon
device. Fixed by Jean Delvare.
- The hwmon device registered by x86_pkg_temp_thermal driver is
redundant because the temperature value reported by
x86_pkg_temp_thermal is already reported by the coretemp driver.
Fixed by Jean Delvare.
- Fix a problem that the cooling device can not be updated properly
if it is initialized at max cooling state. From Ni Wade.
- Fix a problem that OF registered thermal zones are running without
thermal governors. From Zhang Rui.
- Commit beeb5a1e0e ("thermal: rcar-thermal: Enable driver
compilation with COMPILE_TEST") broke build on archs wihout io
memory. Thus make it depend on HAS_IOMEM to bypass build failures.
Fixed by Richard Weinberger"

some slaves and the remainder are fixes for recently introduced bugs
from the past release cycle or so.

This series contains updates to e1000e, ixgbevf and igb.
Majority of this series contains fixes and cleanups to e1000e,
most notably are:
Todd provides a fix to PTP in e1000e which adds a lock in e1000e_phc_adjfreq
to prevent concurrent changes to TIMINCA and SYSTIMH/L. Then provides an
igb fix to use ARRAY_SIZE for array size calculation.
David provides the remaining e1000e which contain:
- cleanup of pointer references that are no longer used
- fix an issue on systems with Management Engine enabled with the
ethernet cable unplugged
- fix an issue on 82579 where enabling EEE LPI sooner than one second
after link up causes link issues on some switches
- refactor the power management flows to prevent the suspend path from
being executed twice when hibernating
- refactor the runtime power management to fix interfering with the
functionality of Energy Efficient Ethernet when enabled and to fix
the device from repeatedly flip between suspend and resume with the
interface administratively downed
- enable the feature PHY Ultra Low Power Mode which is a power saving
feature that reduces the power consumption of the PHY when a cable is
not connected
- fix the ethtool offline tests for 82579 parts
- fix SHRA register access for 82579 parts which was introduced by
previous commit c3a0dce35a "e1000e: fix overrun of PHY RAR array"
Florian provides a fix for ixgbevf where skb->pkt_type was being checked
like a bitmask, but it is not a bitmask.
Fix an issue reported by Stephen Hemminger where there was a warning
about code defined but never used if IGB_HWMON is not defined.

For quite a long time now, workqueue only treats two work items
identical iff both their addresses and callbacks match. This is to
avoid introducing false dependency through the work item being
recycled while being executed. This changes non-reentrancy guarantee
for the users of PREPARE[_DELAYED]_WORK() - if the function changes,
reentrancy isn't guaranteed against the previous instance. Firewire
depended on such nonreentrancy guarantee.
This is fixed by doing the work item multiplexing from firewire proper

The family in the NAT expression is basically completely useless since
we have it available during runtime anyway. Nevertheless it is used to
decide the NAT family, so at least validate it properly. As we don't
support cross-family NAT, it needs to match the family of the table the
expression exists in.
Unfortunately we can't remove it completely since we need to dump it for
userspace (*sigh*), so at least reduce the memory waste.
Additionally clean up the module init function by removing useless
temporary variables.

Previous commit c3a0dce35a fixed an overrun for the RAR on i218 devices.
This commit also attempted to homogenize the RAR/SHRA access for all parts
accessed by the e1000e driver. This change introduced an error for
assigning MAC addresses to guest OS's for 82579 devices.
Only RAR[0] is accessible to the driver for 82579 parts, and additional
addresses must be placed into the SHRA[L|H] registers. The rar_entry_count
was changed in the previous commit to an inaccurate value that accounted
for all RAR and SHRA registers, not just the ones usable by the driver.
This patch fixes the count to the correct value and adjusts the
e1000_rar_set_pch2lan() function to user the correct index.

Valid values for InterruptThrottleRate are 10-100000, or one of
0, 1, 3, 4. '2' is not valid. This is a legacy from the branching
from the e1000 driver code that e1000e was based from.
Prior to this patch, if the e1000e driver was loaded with a forced
invalid InterruptThrottleRate of '2', then no throttle rate would be
set and no error message generated.
Now, a message will be generated that an invalid value was used and the
value for InterruptThrottleRate will be set to the default value.

ULP is a power saving feature that reduces the power consumption of the
PHY when a cable is not connected.
ULP is gated on the following conditions:
1) The hardware must support ULP. Currently this is only I218
devices from Intel
2) ULP is initiated by the driver, so, no driver results in no ULP.
3) ULP's implementation utilizes Runtime Power Management to toggle its
execution. ULP is enabled/disabled based on the state of Runtime PM.
4) ULP is not active when wake-on-unicast, multicast or broadcast is active
as these features are mutually-exclusive.
Since the PHY is in an unavailable state while ULP is active, any access
of the PHY registers will fail. This is resolved by utilizing kernel
calls that cause the device to exit Runtime PM (e.g. pm_runtime_get_sync)
and then, after PHY access is complete, allow the device to resume
Runtime PM (e.g. pm_runtime_put_sync).
Under certain conditions, toggling the LANPHYPC is necessary to disable
ULP mode. Break out existing code to toggle LANPHYPC to a new function
to avoid code duplication.

Refactor the system power management flows to prevent the suspend path from
being executed twice when hibernating since both the freeze and
poweroff callbacks were set to e1000_suspend() via SET_SYSTEM_SLEEP_PM_OPS.
There are HW workarounds that are performed during this flow and calling
them twice was causing erroneous behavior.
Re-arrange the code to take advantage of common code paths and explicitly
set the individual dev_pm_ops callbacks for suspend, resume, freeze,
thaw, poweroff and restore.
Add a boolean parameter (reset) to the e1000e_down function to allow
for cases when the HW should not be reset when downed during a PM event.
Now that all suspend/shutdown paths result in a call to __e1000_shutdown()
that checks Wake on Lan status, removing redundant check for WoL in
e1000_power_down_phy().

On a ME enabled system with the cable out, the driver init flow would
generate an erroneous message indicating that resets were being blocked
by an active ME session. Cause was ME clearing the semaphore bit to
block further PHY resets for up to 50 msec during power-on/cycle. After
this interval, ME would re-set the bit and allow PHY resets.
To resolve this, change the flow of e1000e_phy_hw_reset_generic() to
utilize a delay and retry method. Poll the FWSM register to minimize
any extra time added to the flow. If the delay times out at 100ms
(checked in 10msec increments), then return the value E1000_BLK_PHY_RESET,
as this is the accurate state of the PHY. Attempting to alter just the
call to e1000e_phy_hw_reset_generic() in e1000_init_phy_workarounds_pchlan()
just caused the problem to move further down the flow.

Introduced in commit 5fa10196bd ("x86: Ignore NMIs that come in during

My weak excuse is that the x86 tree generally doesn't introduce stupid

Developers would say they put a trace_printk() before and after the trace
event but when they enable it (and the trace event said it was enabled) they
would see the trace_printks but not the trace event.
I was not able to reproduce this, but that's because I wasn't looking at
the right location. Recently, another bug came up that showed the issue.
If your kernel supports signed modules but allows for non-signed modules
to be loaded, then when one is, the kernel will silently set the
MODULE_FORCED taint on the module. Although, this taint happens without
the need for insmod --force or anything of the kind, it labels the
module with that taint anyway.
If this tainted module has tracepoints, the tracepoints will be ignored
because of the MODULE_FORCED taint. But no error message will be
displayed. Worse yet, the event infrastructure will still be created
letting users enable the trace event represented by the tracepoint,
although that event will never actually be enabled. This is because
the tracepoint infrastructure allows for non-existing tracepoints to
be enabled for new modules to arrive and have their tracepoints set.
Although there are several things wrong with the above, this change
only addresses the creation of the trace event files for tracepoints
that are not created when a module is loaded and is tainted. This change
will print an error message about the module being tainted and not the
trace events will not be created, and it does not create the trace event
infrastructure.

Pull tracing fix from Steven Rostedt:
"In the past, I've had lots of reports about trace events not working.
Developers would say they put a trace_printk() before and after the
trace event but when they enable it (and the trace event said it was
enabled) they would see the trace_printks but not the trace event.
I was not able to reproduce this, but that's because I wasn't looking
at the right location. Recently, another bug came up that showed the
issue.
If your kernel supports signed modules but allows for non-signed
modules to be loaded, then when one is, the kernel will silently set
the MODULE_FORCED taint on the module. Although, this taint happens
without the need for insmod --force or anything of the kind, it labels
the module with that taint anyway.
If this tainted module has tracepoints, the tracepoints will be
ignored because of the MODULE_FORCED taint. But no error message will
be displayed. Worse yet, the event infrastructure will still be
created letting users enable the trace event represented by the
tracepoint, although that event will never actually be enabled. This
is because the tracepoint infrastructure allows for non-existing
tracepoints to be enabled for new modules to arrive and have their
tracepoints set.
Although there are several things wrong with the above, this change
only addresses the creation of the trace event files for tracepoints
that are not created when a module is loaded and is tainted. This
change will print an error message about the module being tainted and
not the trace events will not be created, and it does not create the
trace event infrastructure"
