ASoC: Fixes for v3.17
A few more driver specific fixes on top of the currently pending fixes
(which are already in your tree but not Linus').
Pull an RCU fix from Paul E. McKenney:
"This series contains a single commit fixing an initialization bug
reported by Amit Shah and fixed by Pranith Kumar (and tested by Amit).
This bug results in a boot-time hang in callback-offloaded configurations
where callbacks were posted before the offloading ('rcuo') kthreads
were created."

fc95ca7284 introduces a memset in
kvmppc_alloc_hpt since the general CMA doesn't clear the memory it
allocates.
However, the size argument passed to memset is computed from a signed value
and its signed bit is extended by the cast the compiler is doing. This lead
to extremely large size value when dealing with order value >= 31, and
almost all the memory following the allocated space is cleaned. As a
consequence, the system is panicing and may even fail spawning the kdump
kernel.
This fix makes use of an unsigned value for the memset's size argument to
avoid sign extension. Among this fix, another shift operation which may
lead to signed extended value too is also fixed.

Relax the check on the length of the PKCS#7 cert as it appears that the PE
file wrapper size gets rounded up to the nearest 8.
The debugging output looks like this:
PEFILE: ==> verify_pefile_signature()
PEFILE: ==> pefile_parse_binary()
PEFILE: checksum @ 110
PEFILE: header size = 200
PEFILE: cert = 968 @547be0 [68 09 00 00 00 02 02 00 30 82 09 56 ]
PEFILE: sig wrapper = { 968, 200, 2 }
PEFILE: Signature data not PKCS#7
The wrapper is the first 8 bytes of the hex dump inside []. This indicates a
length of 0x968 bytes, including the wrapper header - so 0x960 bytes of
payload.
The ASN.1 wrapper begins [ ... 30 82 09 56 ]. That indicates an object of size
0x956 - a four byte discrepency, presumably just padding for alignment
purposes.
So we just check that the ASN.1 container is no bigger than the payload and
reduce the recorded size appropriately.
Whilst we're at it, allow shorter PKCS#7 objects that manage to squeeze within
127 or 255 bytes. It's just about conceivable if no X.509 certs are included
in the PKCS#7 message.

After commit d431cbc53c (PM / sleep: Simplify sleep states sysfs
interface code) the pm_states[] array is not populated initially,
which causes setup_test_suspend() to always fail and the suspend
testing during boot doesn't work any more.
Fix the problem by using pm_labels[] instead of pm_states[] in
setup_test_suspend() and storing a pointer to the label of the
sleep state to test rather than the number representing it,
because the connection between the state numbers and labels is
only established by suspend_set_ops().

pull request: Netfilter/IPVS fixes for net
The following patchset contains seven Netfilter fixes for your net
tree, they are:
1) Make the NAT infrastructure independent of x_tables, some users are
already starting to test nf_tables with NAT without enabling x_tables.
Without this patch for Kconfig, there's a superfluous dependency
between NAT and x_tables.
2) Allow to use 0 in the cgroup match, the kernel rejects with -EINVAL
with no good reason. From Daniel Borkmann.
3) Select CONFIG_NF_NAT from the nf_tables NAT expression, this also
resolves another NAT dependency with x_tables.
4) Use HAVE_JUMP_LABEL instead of CONFIG_JUMP_LABEL in the Netfilter hook
code as elsewhere in the kernel to resolve toolchain problems, from
Zhouyi Zhou.
5) Use iptunnel_handle_offloads() to set up tunnel encapsulation
depending on the offload capabilities, reported by Alex Gartrell
patch from Julian Anastasov.
6) Fix wrong family when registering the ip_vs_local_reply6() hook,
also from Julian.
7) Select the NF_LOG_* symbols from NETFILTER_XT_TARGET_LOG. Rafał
Miłecki reported that when jumping from 3.16 to 3.17-rc, his log
target is not selected anymore due to changes in the previous
development cycle to accomodate the full logging support for
nf_tables.

Some hosts can be both little and big endian.
In certain scenarios a big endian kernel can kexec a little endian kernel.
This patch fixes this case from both ends:
1) Return endianity to original values on shutdown (in case little endian kernel boots after we shutdown).
2) Do not rely on HW reset values when loading driver in little endian kernel
but configure them explicitly (in case previous kernel was big endian and did not reset the HW).

When qeth device is queried for ethtool data, hardware operation
is performed to extract the necessary information from the card.
If the card is not online at the moment (e.g. it is undergoing
recovery), this operation produces undesired effects like
temporarily freezing the system. This patch prevents execution
of the hardware query operation when the card is not online.
In such case, ioctl() operation returns error with errno ENODEV.

The patch fixes race conditions between PCI error recovery callbacks and
potential ifup/ifdown.
First, if ifup (tg3_open) is called between tg3_io_error_detected() and
tg3_io_resume() then tp->timer is armed twice before expiry. Once during
tg3_open() and again during tg3_io_resume(). This results in BUG
at kernel/time/timer.c:945.
Second, if ifdown (tg3_close) is called between tg3_io_error_detected()
and tg3_io_resume() then tg3_napi_disable() is called twice without
a tg3_napi_enable between. Once during tg3_io_error_detected() and again
during tg3_close(). The tg3_io_resume() then hangs on rtnl_lock().

be2net: patch set
v2 changes: add a new line after variable declaration in patch 12.
***
Patch 1 adds a few new log messages to help debugging in failure cases.
Patch 2 uses new macros for parsing RX/TX completions and TX wrbs to
help shorten the lines.
Patch 3 adds a description for the RX counter rx_input_fifo_overflow_drop.
Patch 4 adds TX completion error statistics reporting via ethtool.
Patch 5 adds a dma_mapping_error counter and its reporting via ethtool.
Patch 6 fixes up log messages in the Lancer FW download path.
Patch 7 replaces gotos with direct return statements.
Patch 8 cleans up be_change_mtu() code by using a new macro BE_MAX_MTU
Patch 9 makes be_cmd_get_regs() routine to return an integer status
similar to other FW cmd routines in be_cmds.c
Patch 10 gets rid of TX budget as enforcing a budget on TX completion
processing in NAPI is neither suggested nor it provides a performance benefit.
Patch 11 defines and uses a new macro for_all_tx_queues_on_eq() similar
to the RX processing code.
Patch 12 queries max_tx_qs from the FW for BE3 super-nic profiles.
For those profiles, the driver cannot assume a constant BE3_MAX_TX_QS value,
as the value may change for each function.
