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.

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

John W. Linville says:
====================
Here is another handful of late-breaking fixes intended for the 3.8
stream... Hopefully the will still make it! :-)
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.

[Problem]
efi_pstore creates sysfs entries, which enable users to access to NVRAM,
in a write callback. If a kernel panic happens in an interrupt context,
it may fail because it could sleep due to dynamic memory allocations during
creating sysfs entries.
[Patch Description]
This patch removes sysfs operations from a write callback by introducing
a workqueue updating sysfs entries which is scheduled after the write
callback is called.
Also, the workqueue is kicked in a just oops case.
A system will go down in other cases such as panic, clean shutdown and emergency
restart. And we don't need to create sysfs entries because there is no chance for
users to access to them.
efi_pstore will be robust against a kernel panic in an interrupt context with this patch.

[Problem]
There is a scenario which efi_pstore fails to log messages in a panic case.
- CPUA holds an efi_var->lock in either efivarfs parts
or efi_pstore with interrupt enabled.
- CPUB panics and sends IPI to CPUA in smp_send_stop().
- CPUA stops with holding the lock.
- CPUB kicks efi_pstore_write() via kmsg_dump(KSMG_DUMP_PANIC)
but it returns without logging messages.
[Patch Description]
This patch disables an external interruption while holding efivars->lock
as follows.
In efi_pstore_write() and get_var_data(), spin_lock/spin_unlock is
replaced by spin_lock_irqsave/spin_unlock_irqrestore because they may
be called in an interrupt context.
In other functions, they are replaced by spin_lock_irq/spin_unlock_irq.
because they are all called from a process context.
By applying this patch, we can avoid the problem above with
a following senario.
- CPUA holds an efi_var->lock with interrupt disabled.
- CPUB panics and sends IPI to CPUA in smp_send_stop().
- CPUA receives the IPI after releasing the lock because it is
disabling interrupt while holding the lock.
- CPUB waits for one sec until CPUA releases the lock.
- CPUB kicks efi_pstore_write() via kmsg_dump(KSMG_DUMP_PANIC)
And it can hold the lock successfully.

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
called.

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,
but an upcoming change in hostapd may mean a similar
scenario as for managed mode, therefore do the update
unconditionally.

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.

If we haven't heard a beacon before we associate we can
still start the association process and set the MAC in
the firmware to associated only after having received a
beacon with DTIM period by reacting to the new change
flag (BSS_CHANGED_DTIM_PERIOD) from mac80211.
This reduces the association time in these cases.

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.

__netpoll_rcu_free is used to free netpoll structures when the rtnl_lock is
already held. The mechanism is used to asynchronously call __netpoll_cleanup
outside of the holding of the rtnl_lock, so as to avoid deadlock.
Unfortunately, __netpoll_cleanup modifies pointers (dev->np), which means the
rtnl_lock must be held while calling it. Further, it cannot be held, because
rcu callbacks may be issued in softirq contexts, which cannot sleep.
Fix this by converting the rcu callback to a work queue that is guaranteed to
get scheduled in process context, so that we can hold the rtnl properly while
calling __netpoll_cleanup
Tested successfully by myself.

The band field for the supported channels were left unpopulated, making
them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels.
This resulted in null pointer accesses if anything tries to access
wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since
wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).

There are only a few drivers that use HW scan, and
all of those don't need a non-idle transition before
starting the scan -- some don't even care about idle
at all. Remove the flag and code associated with it.
The only driver that really actually needed this is
wl1251 and it can just do it itself in the hw_scan
callback -- implement that.

While technically the TSF isn't an IE, it can be
necessary to distinguish between the TSF from a
beacon and a probe response, in particular in
order to know the next DTIM TBTT, as not all APs
are spec compliant wrt. TSF==0 being a DTIM TBTT
and thus the DTIM count needs to be taken into
account as well.
To allow this, move the TSF into the IE struct
so it can be known whence it came.

There's no way scan BSS IEs can be NULL as even
if the allocation fails the frame is discarded.
Remove some code checking for this and document
that it is always non-NULL.

This prepares for using the spinlock instead of krefs
which is needed in the next patch to track the refs
of combined BSSes correctly.

The MEI bus API changed according to the latest comments from the char-misc
maintainers, and this patch fixes the microread mei physical layer code
according to those changes:
We pass the MEI id back to the probe routine, and the mei_driver takes a
table of MEI ids instead of one static id.
Also, mei_bus_driver got renamed to mei_driver, mei_bus_client to
mei_device, and mei_bus_set/get_clientdata to mei_set/get_clientdata.

In preparation to support the regmap debugfs ranges functionality
factor this code out to a separate function. We'll need to ensure
that the value has been correctly calculated from two separate places
in the code.
