The bnx2x gso_type setting bug fix in 'net' conflicted with
changes in 'net-next' that broke the gso_* setting logic
out into a seperate function, which also fixes the bug in
question. Thus, use the 'net-next' version.

The designed workflow for the caches in kmemcg is: register it with
memcg_register_cache() if kmemcg is already available or later on when a
new kmemcg appears at memcg_update_cache_sizes() which will handle all
caches in the system. The caches created at boot time will be handled
by the later, and the memcg-caches as well as any system caches that are
registered later on by the former.
There is a bug, however, in memcg_register_cache: we correctly set up
the array size, but do not mark the cache as a root cache.
This means that allocations for any cache appearing late in the game
will see memcg->memcg_params->is_root_cache == false, and in particular,
trigger VM_BUG_ON(!cachep->memcg_params->is_root_cache) in
__memcg_kmem_cache_get.
The obvious fix is to include the missing assignment.

With commit 8e72033f2a48 ("thp: make MADV_HUGEPAGE check for
mm->def_flags") the VM_NOHUGEPAGE flag may be set on s390 in
mm->def_flags for certain processes, to prevent future thp mappings.
This would be overwritten by do_mlockall(), which sets it back to 0 with
an optional VM_LOCKED flag set.
To fix this, instead of overwriting mm->def_flags in do_mlockall(), only
the VM_LOCKED flag should be set or cleared.

Commit e7e034e18a0a ("drivers/rtc/rtc-pl031.c: fix the missing operation
on enable") accidentally broke the ST variants of PL031.
The bit that is being poked as "clockwatch" enable bit for the ST
variants does the work of bit 0 on this variant. Bit 0 is used for a
clock divider on the ST variants, and setting it to 1 will affect
timekeeping in a very bad way.

commit (32f5376 netfilter: nf_ct_helper: disable automatic helper
re-assignment of different type) broke transparent proxy scenarios.
For example, initial helper lookup might yield "ftp" (dport 21),
while re-lookup after REDIRECT yields "ftp-2121".
This causes the autoassign code to toss the ftp helper, even
though these are just different instances of the same helper.
Change the test to check for the helper function address instead
of the helper address, as suggested by Pablo.

Until now, the MPC5200 FEC ethernet driver relied upon the bootloader
(U-Boot) to write the MAC address into the ethernet controller
registers. The Linux driver should not rely on such a thing. So
lets read the MAC address from the DT as it should be done here.
The following priority is now used to read the MAC address:
1) First, try OF node MAC address, if not present or invalid, then:
2) Read from MAC address registers, if invalid, then:
3) Log a warning message, and choose a random MAC address.
This fixes a problem with a MPC5200 board that uses the SPL U-Boot
version without FEC initialization before Linux booting for
boot speedup.
Additionally a status line is now be printed upon successful
driver probing, also displaying this MAC address.

The CPSW switch can act as Dual EMAC by segregating the switch ports
using VLAN and port VLAN as per the TRM description in
14.3.2.10.2 Dual Mac Mode
Following CPSW components will be common for both the interfaces.
* Interrupt source is common for both eth interfaces
* Interrupt pacing is common for both interfaces
* Hardware statistics is common for all the ports
* CPDMA is common for both eth interface
* CPTS is common for both the interface and it should not be enabled on
both the interface as timestamping information doesn't contain port
information.
Constrains
* Reserved VID of One port should not be used in other interface which will
enable switching functionality
* Same VID must not be used in both the interface which will enable switching
functionality

There are three mac80211 fixes pulled from Johannes:
"Here are three fixes still for the 3.8 stream, the fix from Cong Ding
for the bad sizeof (Stephen Hemminger had pointed it out before but I'd
promptly forgotten), a mac80211 managed-mode channel context usage fix
where a downgrade would never stop until reaching non-HT and a bug in
the channel determination that could cause invalid channels like HT40+
on channel 11 to be used."
Also included is a mwl8k fix that avoids an oops when using mwl8k
devices that only support the 5 GHz band.
Please let me know if there are problems!

The original fix that was applied for setting gso_type required more change
than necessary because it was assumed ixgbe does RSC on IPv6 frames and this
is not correct. RSC is only supported with IPv4/TCP frames only. As such we
can simplify the fix and avoid the unnecessary move of eth_type_trans.
The previous patch "ixgbe: fix gso type" and this patch reduce the entire fix
to one line that sets gso_type to TCPV4 if the frame is RSC.

Commit 12ad100046: "clockevents: Add generic timer broadcast function"
made tick_device_uses_broadcast set up the generic broadcast function
for dummy devices (where !tick_device_is_functional(dev)), but neglected
to set up the broadcast function for devices that stop in low power
states (with the CLOCK_EVT_FEAT_C3STOP flag).
When these devices enter low power states they will not have the generic
broadcast function assigned, and will bring down the system when an
attempt is made to broadcast to them.
This patch ensures that the broadcast function is also assigned for
devices which require broadcast in low power states.

This partially reverts commit 44ba973699b831414c3f8eef68ee5a7fe1208a05.
rate_control_rate_init assumes the rate_init member of
struct rate_control_ops is not NULL therefore not initializing it leads to
an oops as soon the driver succesfully associates to an AP.
The removal of rate_update from 44ba973699b831414c3f8eef68ee5a7fe1208a05
is ok because rate_update is checked for NULL before being

In managed mode, the HT/VHT capabilities aren't set when
the station is initially added, so update the station
when it is marked associated. In AP/GO mode, the station
will typically be added with full capabilities today,

Now that mac80211 no longer starts the auth/assoc
timeouts when it transmits the frame, but only when
the frame status arrives, we no longer need to wait
for the session protection time event to start, we
can schedule it and enqueue the auth/assoc frame
right away. This reduces the amount of time we block
mac80211's workqueue.
Also, since now we no longer need different behavior
for session protection and P2P time events, refactor
the code to have just a common implementation.

Implement proper WoWLAN wakeup and query the wakeup
reasons, then report them to userspace.
Note that this is tricky: a firmware bug (that has
been fixed in later versions) means that the status
command response isn't properly closed in hardware
and thus won't arrive at the host. Sending another
command after it closes the status response but the
next command gets stuck, etc. We reset the device
after querying though, so this is not a big issue,
just makes for strange code.

The match 00:xx:00:00:xx:00:00:00:00:xx:xx:xx (where xx indicates
"don't care") should be represented by a pattern of twelve zero
bytes, and a mask of "0xed,0x01", not "0xed,0x07".
mask_len = (pat_len + 7) / 8 = (12 + 7) / 8 = 2
Hence the mask will be of 2 bytes.
Replace each valid byte in pattern by 1 and don't care byte by 0:
10110111 1000 (0000)
1st byte of pattern corresponds to lower order bit in first byte
of mask. And 9th byte of pattern corresponds to lower order bit
in second byte of mask. With this logic the mask will be
11101101 00000001 = 0xed 0x01

When ever parsing cmd buffer supplied by userspace we need to use
radeon_get_ib_value rather than directly accessing the ib as the user
cmd might not yet be copied into the ib thus the parser might read
value that does not correspond to what user is sending and possibly
allowing user to send malicious command undected.

This patch trims the MMR register definitions after the updates for the
SGI UV3 system have been applied. Note that because these definitions
are automatically generated from the RTL we cannot control the length
of the names. Therefore there are lines that exceed 80 characters.
