cleared and reinitialize the device, whether the SELECTIVE_SUSPEND is set
or not. If reset_resume() is called, it means the power supply is cut or the

ARM allmodconfig fails because of the addition of the FMAN driver:

drivers/built-in.o: In function `start':
binder.c:(.text+0x176078): undefined reference to `phy_start'
The reason is that the driver uses PHYLIB, but that is a loadable
module here, and fman itself is built-in.
This patch makes it possible to configure fman as a module as well
so we don't change the status of PHYLIB in an allmodconfig kernel,
and it adds a 'select PHYLIB' statement to ensure that phylib is
always built-in when fman is.
The driver uses "builtin_platform_driver(fman_driver);", which means
it cannot be unloaded, but it's still possible to have it as a loadable
module that gets loaded once and never removed.

Moving the caller of iptunnel_xmit_stats causes a build error in

The reason is that the iptunnel_xmit_stats definition is hidden

Backport of this upstream commit into stable kernels :
89c22d8c3b ("net: Fix skb csum races when peeking")
exposed a bug in udp stack vs MSG_PEEK support, when user provides
a buffer smaller than skb payload.
In this case,
skb_copy_and_csum_datagram_iovec(skb, sizeof(struct udphdr),
msg->msg_iov);
returns -EFAULT.
This bug does not happen in upstream kernels since Al Viro did a great
job to replace this into :
skb_copy_and_csum_datagram_msg(skb, sizeof(struct udphdr), msg);
This variant is safe vs short buffers.
For the time being, instead reverting Herbert Xu patch and add back
skb->ip_summed invalid changes, simply store the result of
udp_lib_checksum_complete() so that we avoid computing the checksum a
second time, and avoid the problematic
skb_copy_and_csum_datagram_iovec() call.
This patch can be applied on recent kernels as it avoids a double
checksumming, then backported to stable kernels as a bug fix.

bnxt_en: Support combined and rx/tx channels.
The bnxt hardware uses a completion ring for rx and tx events. The driver
has to process the completion ring entries sequentially for the events.
The current code only supports an rx/tx ring pair for each completion ring.
This patch series add support for using a dedicated completion ring for
rx only or tx only as an option configuarble using ethtool -L.
The benefits for using dedicated completion rings are:
1. A burst of rx packets can cause delay in processing tx events if the
completion ring is shared. If tx queue is stopped by BQL, this can cause
delay in re-starting the tx queue.
2. A completion ring is sized according to the rx and tx ring size rounded
up to the nearest power of 2. When the completion ring is shared, it is
sized by adding the rx and tx ring sizes and then rounded to the next power
of 2, often with a lot of wasted space.
3. Using dedicated completion ring, we can adjust the tx and rx coalescing
parameters independently for rx and tx.

In order to support dedicated or shared completion rings, the ring

completion ring index.
2. rx rings 0 to n will be mapped to completion rings 0 to n.
3. If tx and rx rings share completion rings, then tx rings 0 to m will
be mapped to completion rings 0 to m.
4. If tx and rx rings use dedicated completion rings, then tx rings 0 to
m will be mapped to completion rings n + 1 to n + m.
5. Each tx or rx ring will use the corresponding completion ring index
for doorbell mapping and MSIX mapping.

Currently, an rx and a tx ring are always paired with a completion ring.
We want to restructure it so that it is possible to have a dedicated
completion ring for tx or rx only.
The bnxt hardware uses a completion ring for rx and tx events. The driver
has to process the completion ring entries sequentially for the rx and tx
events. Using a dedicated completion ring for rx only or tx only has these
benefits:
1. A burst of rx packets can cause delay in processing tx events if the
completion ring is shared. If tx queue is stopped by BQL, this can cause
delay in re-starting the tx queue.
2. A completion ring is sized according to the rx and tx ring size rounded
up to the nearest power of 2. When the completion ring is shared, it is
sized by adding the rx and tx ring sizes and then rounded to the next power
of 2, often with a lot of wasted space.
3. Using dedicated completion ring, we can adjust the tx and rx coalescing
parameters independently for rx and tx.
The first step is to separate the rx and tx ring structures from the
bnxt_napi struct.
In this patch, an rx ring and a tx ring will point to the same bnxt_napi
struct to share the same completion ring. No change in ring assignment
and mapping yet.

Kernel panic - not syncing: Fatal exception
When the first time find_next calls find_next_mod_format, it should
iterate the trace_bprintk_fmt_list to find the first print format of
the module. However in current code, start_index is smaller than *pos
at first, and code will not iterate the list. Latter container_of will
get the wrong address with former v, which will cause mod_fmt be a
meaningless object and so is the returned mod_fmt->fmt.
This patch will fix it by correcting the start_index. After fixed,
when the first time calls find_next_mod_format, start_index will be
equal to *pos, and code will iterate the trace_bprintk_fmt_list to
get the right module printk format, so is the returned mod_fmt->fmt.

This patch adds checking the "CRC_OK" bit at the end of packets coming
from the CC2520 radio. It also adds support for putting the radio in
promiscuous mode (in which packets are not dropped if the CRC fails).
In promiscuous mode the AUTOCRC flag is cleared so that the driver can
pass the received CRC to the monitors.
The radio now defaults to frame filtering (checking that the destination
and PANID in the incoming packet matches the local node). This matches
the other 15.4 radios and is what a user would expect to be the default.

11) Mission initialization of wq->flags in sock_alloc_inode(), from
Nicolai Stange.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (35 commits)
sctp: sctp should release assoc when sctp_make_abort_user return NULL in sctp_close
net, socket, socket_wq: fix missing initialization of flags
drivers: net: cpsw: fix error return code
openvswitch: Fix template leak in error cases.
sctp: label accepted/peeled off sockets
sctp: use GFP_USER for user-controlled kmalloc
qlcnic: fix a loop exit condition better
net: cdc_ncm: avoid changing RX/TX buffers on MTU changes
geneve: initialize needed_headroom
ipv6: honor ifindex in case we receive ll addresses in router advertisements
addrconf: always initialize sysctl table data
ipv6/addrlabel: fix ip6addrlbl_get()
switchdev: bridge: Pass ageing time as clock_t instead of jiffies
sh_eth: fix 16-bit descriptor field access endianness too
veth: don’t modify ip_summed; doing so treats packets with bad checksums as good.
net: usb: cdc_ncm: Adding Dell DW5813 LTE AT&T Mobile Broadband Card
net: usb: cdc_ncm: Adding Dell DW5812 LTE Verizon Mobile Broadband Card
natsemi: add checks for dma mapping errors
rhashtable: Kill harmless RCU warning in rhashtable_walk_init
openvswitch: correct encoding of set tunnel action attributes
...
The GLIBC folks would like to eliminate socketcall support
eventually, and this makes sense regardless so wire them
all up.

pull request: bluetooth-next 2015-12-31
Here's (probably) the last bluetooth-next pull request for the 4.5
kernel:
- Add support for BCM2E65 ACPI ID
- Minor fixes/cleanups in the bcm203x & bfusb drivers
- Minor debugfs related fix in 6lowpan code
Please let me know if there are any issues pulling. Thanks.

"iter" is -1 at the end of the loop and not zero. It means we don't
print a warning message.

The function can return negative values in case of error.
Its result should be then tested for such case.
The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].
