As part of a workaround for a hardware erratum in the SFC9100 family
(SF bug 35388), the TX_DESC_UPD_DWORD register address is also used
for communicating with the event block, and only descriptor pointer
values < 2048 are valid.
If the TX DMA ring size is increased to 4096 descriptors (which the
firmware still allows) then we may write a descriptor pointer
value >= 2048, which has entirely different and undesirable effects!
Limit the TX DMA ring size correctly when this workaround is in
effect.

Make sure the practice set by commit 0afb166 "vxlan: Add capability
of Rx checksum offload for inner packet" is applied when the skb
goes through the portion of the RX code which is shared between
vxlan netdevices and ovs vxlan port instances.

commit a622260254ee48("ip_tunnel: fix kernel panic with icmp_dest_unreach")
clear IPCB in ip_tunnel_xmit() , or else skb->cb[] may contain garbage from
GSO segmentation layer.
But commit 0e6fbc5b6c621("ip_tunnels: extend iptunnel_xmit()") refactor codes,
and it clear IPCB behind the dst_link_failure().
So clear IPCB in ip_tunnel_xmit() just like commti a622260254ee48("ip_tunnel:
fix kernel panic with icmp_dest_unreach").

We possibly retrieve the adapter's statistics during EEH recovery
and that should be disallowed. Otherwise, it would possibly incur
replicate EEH error and EEH recovery is going to fail eventually.
The patch reuses statistics lock and checks net_device is attached
before going to retrieve statistics, so that the problem can be
avoided.

If we have EEH error happens to the adapter and we have to remove
it from the system for some reasons (e.g. more than 5 EEH errors
detected from the device in last hour), the adapter will be disabled
for towice separately by eeh_err_detected() and remove_one(), which
will incur following unexpected backtrace. The patch tries to avoid
it.

When we have multiple devices attempting to sync the same address
to a single destination, each device should be permitted to sync
it once. To accomplish this, pass the 'sync_cnt' of the source
address when adding the addresss to the lower device. 'sync_cnt'
tracks how many time a given address has been succefully synced.
This way, we know that if the 'sync_cnt' passed in is 0, we should
sync this address.
Also, turn 'synced' member back into the counter as was originally
done in
commit 4543fbefe6e06a9e40d9f2b28d688393a299f079.
net: count hw_addr syncs so that unsync works properly.
It tracks how many time a given address has been added via a
'sync' operation. For every successfull 'sync' the counter is
incremented, and for ever 'unsync', the counter is decremented.
This makes sure that the address will be properly removed from
the the lower device when all the upper devices have removed it.

A socket may be v6/v4-mapped. In that case sk->sk_family is AF_INET6,
but the IP being used is actually an IPv4-address.
Current's tcp-metrics will thus represent it as an IPv6-address:
root@server:~# ip tcp_metrics
::ffff:10.1.1.2 age 22.920sec rtt 18750us rttvar 15000us cwnd 10
10.1.1.2 age 47.970sec rtt 16250us rttvar 10000us cwnd 10
This patch modifies the tcp-metrics so that they are able to handle the
v6/v4-mapped sockets correctly.

This patch changes percpu_ida_alloc() + callers to accept task state
bitmask for prepare_to_wait() for code like target/iscsi that needs
it for interruptible sleep, that is provided in a subsequent patch.
It now expects TASK_UNINTERRUPTIBLE when the caller is able to sleep
waiting for a new tag, or TASK_RUNNING when the caller cannot sleep,
and is forced to return a negative value when no tags are available.
v2 changes:
- Include blk-mq + tcm_fc + vhost/scsi + target/iscsi changes
- Drop signal_pending_state() call
v3 changes:
- Only call prepare_to_wait() + finish_wait() when != TASK_RUNNING

In map_groups__find_symbol() map->map_ip is used without ensuring the
map is loaded. Then the address passed to map->map_ip isn't mapped at
the first time.
E.g. below code always fails to get a symbol at the first call;
addr = /* Somewhere in the kernel text */
symbol_conf.try_vmlinux_path = true;
symbol__init();
host_machine = machine__new_host();
sym = machine__find_kernel_function(host_machine,
addr, NULL, NULL);
/* Note that machine__find_kernel_function calls
map_groups__find_symbol */
This ensures it by calling map__load before using it in
map_groups__find_symbol().

The plugindir_SQ definition contains $(prefix) which is not needed as
the $(libdir) definition already contains prefix in it. This leads to
the path including an extra prefix in it, e.g. /usr/usr/lib64.
The -DPLUGIN_DIR defintion includes DESTDIR. This is incorrect, as it
sets the plugin search path to include the value of DESTDIR. DESTDIR is
a mechanism to install in a non-standard location such as a chroot or an
RPM build root. In the RPM case, this leads to the search path being
incorrect after the resulting RPM is installed (or in some cases an RPM
build failure).
Remove both of these unnecessary inclusions.

"This is primarily bug fixes, many of which you already have. New

are some merge commits in there on account of that. I'm afraid I
didn't do a good job of putting meaningful comments in the first
couple of merges. Sorry about that. I think I have the hang of it
now.

discard, growfs, memory leaks in recovery, directory v2, quotas, the
MAINTAINERS file, allocation alignment, extent list locking, and in
xfs_bmapi_allocate. There are cleanups in xfs_setsize_buftarg,
removing unused macros, quotas, setattr, and freeing of inode
clusters. The in-memory and on-disk log format have been decoupled, a
common helper to calculate the number of blocks in an inode cluster
has been added, and handling of i_version has been pulled into the
filesystems that use it.

inode info from attributes. Which means corrupted storage.
Let it be an empty ZERO dated directory entry so it can be
deleted. Otherwise the all directory will be inaccessible.
This does not loose data, because if there is an orphan object
somewhere it will be recovered by fschk. But usually this only
means corrupted dir entry. The object was never generated and
only its link exist. This way we can delete the bad entry.

With this minimal do nothing patch an application can open O_DIRECT
and then actually do buffered sync IO instead. But the aio API is
supported which is a good thing

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/boards
Split omap3 core padconf area into two as some of the registers in
the padconf area are not accessible and used for other devices.
Also fix the interrupt number for omap2 RNG, and add basic support
for sbc-3xxx with cm-t3730.
Note that the minor merge conflicts for omap_hwmod_2xxx_ipblock_data.c
can be solved by just dropping the legacy hwmod data for interrupts
for v3.14.

In the case of target returning OSD_ERR_PRI_CLEAR_PAGES when we
only sent for attributes don't crash on NULL bio.
This is an osd-target bug but don't crash regardless

The head number of a given display controller is fixed in hardware and
required to program outputs appropriately. Relying on the driver probe
order to determine this number will not work, since that could yield a
situation where the second head was probed first and would be assigned
head number 0 instead of 1.
By explicitly specifying the head number in the device tree, it is no
longer necessary to rely on these assumptions. As a fallback, if the
property isn't available, derive the head number from the display
controller node's position in the device tree. That's somewhat more
reliable than the previous default but not a proper solution.

Since we keep the clock value linearly continuous on frequency change,
make sure the initial multiplier is 0, such that our initial value is 0.
Without this we compute the initial value at whatever the TSC has
managed to reach since power-on.

The code would assume sched_clock_stable() and switch to !stable
later, this switch brings a discontinuity in time.
The discontinuity on switching from stable to unstable was always
present, but previously we would set stable/unstable before
initializing TSC and usually stick to the one we start out with.
So the static_key bits brought an extra switch where there previously
wasn't one.
Things are further complicated by the fact that we cannot use
static_key as early as we usually call set_sched_clock_stable().
Fix things by tracking the stable state in a regular variable and only
set the static_key to the right state on sched_clock_init(), which is
ran right after late_time_init->tsc_init().
Before this we would not be using the TSC anyway.

The #ifdef CONFIG_PREEMPT is both not needed and wrong.
Its not required because asm/preempt.h should provide
{set,clear}_preempt_need_resched() regardless and its wrong because
for voluntary preempt we still rely on PREEMPT_NEED_RESCHED.
