The {i3200|i7core|sb|skx}_edac drivers show DIMM capacity using the
wrong unit symbol: 'Mb' - megabit. Fix them by replacing 'Mb' with
'MiB' - mebibyte.

In commit 9f480fae ("crypto: chacha20 - Fix keystream alignment for
chacha20_block()"), I had missed that chacha20_block() can be called
directly on the buffer passed to get_random_bytes(), which can have any
alignment.  So, while my commit didn't break anything, it didn't fully
solve the alignment problems.

Revert my solution and just update chacha20_block() to use
put_unaligned_le32(), so the output buffer need not be aligned.
This is simpler, and on many CPUs it's the same speed.

But, I kept the 'tmp' buffers in extract_crng_user() and
_get_random_bytes() 4-byte aligned, since that alignment is actually
needed for _crng_backtrack_protect() too.

[ Upstream commit c29de84149aba5f74e87b6491c13ac7203c12f55 ]

The PCI port driver saves the PCI state after initializing the device with
the applicable service devices.  This was, however, before the service
drivers were even registered because PCI probe happens before the
device_initcall initialized those service drivers.  The config space state
that the services set up were not being saved.  The end result would cause
PCI devices to not react to events that the drivers think they did if the
PCI state ever needed to be restored.

Fix this by changing the service drivers from using the init calls to
having the portdrv driver calling the services directly.  This will get the
state saved as desired, while making the relationship between the port
driver and the services under it more explicit in the code.

The function of genphy_read_status is that reading phy information
from HW and using these information to update SW variable. If user
is using ethtool to setting the speed of phy and service task is calling
by hclge_get_mac_phy_link, the result of speed setting is uncertain.
Because ethtool cmd will modified phydev and hclge_get_mac_phy_link also
will modified phydev.

Because phy state machine will update phy link periodically, we can
just use phydev->link to check the link status. This patch removes
function call of genphy_read_status. To ensure accuracy, this patch
adds a phy state check. If phy state is not PHY_RUNNING, we consider
link is down. Because in some scenarios, phydev->link may be link up,
but phy state is not PHY_RUNNING. This is just an intermediate state.
In fact, the link is not ready yet.

simultaneous access (addition/removal) to it and that would be racy.
Extend scope of the opp_table lock to protect dev_list as well.

Commit f27b4746 ("i40iw: add connection management code") uses an
incorrect rcu iterator, whilst holding the rtnl_lock. Since the
critical region invokes i40iw_manage_qhash(), which is a sleeping
function, the rcu locking and traversal cannot be used.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, also the implementation in this
driver has returns 'netdev_tx_t' value, so just change the function
return type to netdev_tx_t.

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/char/ipmi/ipmi_msghandler.c: In function 'ipmi_set_my_LUN':
drivers/char/ipmi/ipmi_msghandler.c:1335:13: warning:
 variable 'rv' set but not used [-Wunused-but-set-variable]
  int index, rv = 0;

'rv' should be the correct return value.
