57439f878a fs: fix superblock iteration race
list_for_each_entry_safe is not suitable to protect against concurrent
modification of the list. 6754af6 introduced a race in sb walking.

list_for_each_entry can use the trick of pinning the current entry in
the list before we drop and retake the lock because it subsequently
follows cur->next. However list_for_each_entry_safe saves n=cur->next
for following before entering the loop body, so when the lock is
dropped, n may be deleted.

4303ef19c6 KEYS: Propagate error code instead of returning -EINVAL
This is from a Smatch check I'm writing.

strncpy_from_user() returns -EFAULT on error so the first change just
silences a warning but doesn't change how the code works.

The other change is a bug fix because install_thread_keyring_to_cred()
can return a variety of errors such as -EINVAL, -EEXIST, -ENOMEM or
-EKEYREVOKED.

1ce368ff28 isdn/gigaset: encode HLC and BC together
Adapt to buggy device firmware which accepts setting HLC only in the
same command line as BC, by encoding HLC and BC in a single command
if both are specified, and rejecting HLC without BC.

23b36778b4 isdn/gigaset: correct CAPI DATA_B3 Delivery Confirmation
The Gigaset CAPI driver handled all DATA_B3_REQ messages as if the
Delivery Confirmation flag bit was set, delaying the emission of the
DATA_B3_CONF reply until the data was actually transmitted. Some
CAPI applications (notably Asterisk) aren't happy with that
behaviour. Change it to actually evaluate the Delivery Confirmation
flag as described the CAPI specification.

278a582989 isdn/gigaset: correct CAPI voice connection encoding
Make the Gigaset CAPI driver select L2_VOICE (AT^SBPR=2) as the
layer 2 encoding for transparent connections, like the ISDN4Linux
variant.  L2_BITSYNC (AT^SBPR=0) mutes internal connections and
distorts external ones.

e7752ee280 isdn/gigaset: honor CAPI application's buffer size request
Fix the Gigaset CAPI driver to limit the length of a connection's
payload data receive buffers to the corresponding CAPI application's
data buffer size, as some real-life CAPI applications tend to be
rather unhappy if they receive bigger data blocks than requested.

9f888160bd ipv6: fix NULL reference in proxy neighbor discovery
The addition of TLLAO option created a kernel OOPS regression
for the case where neighbor advertisement is being sent via
proxy path.  When using proxy, ipv6_get_ifaddr() returns NULL
causing the NULL dereference.

0d98bb2656 sched: Prevent compiler from optimising the sched_avg_update() loop
GCC 4.4.1 on ARM has been observed to replace the while loop in
sched_avg_update with a call to uldivmod, resulting in the
following build failure at link-time:

kernel/built-in.o: In function `sched_avg_update':
 kernel/sched.c:1261: undefined reference to `__aeabi_uldivmod'
 kernel/sched.c:1261: undefined reference to `__aeabi_uldivmod'
make: *** [.tmp_vmlinux1] Error 1

This patch introduces a fake data hazard to the loop body to
prevent the compiler optimising the loop away.
