The change to make xfrm_state objects hash on source address
broke the case where such source addresses are wildcarded.
Fix this by doing a two phase lookup, first with fully specified
source address, next using saddr wildcarded.

dma_map_sg could return a value different to 'nents' argument of
dma_map_sg so the ide stack needs to save it for the later usage
(e.g. for_each_sg).
The ide stack also needs to save the original sg_nents value for
pci_unmap_sg.

Changing the mac address when a macvlan device is up will leave the
device on the wrong hash chain making it impossible to receive
packets.
There is no checking of the mac address set on the macvlan. Allowing
a misconfiguration to grab packets from the the underlying device or
another macvlan.
To resolve these problems I update the hash table of macvlans when the
mac address of a macvlan changes, and when updating the hash table
I verify that the new mac address is usable.
The result is well defined and predictable if not perfect handling of
mac vlan mac addresses.
To keep the code clear I have created a set of hash table maintenance
in macvlan so I am not open coding the hash function and the logic
needed to update the hash table all over the place.

When running in a network namespace whose only link to

able to create another macvlan is a real pain.
So modify macvlan creation to allow automatically forward

of a macvlan on the underlying network device.

Samsung DB-P70 somehow botched the first ICH9 SATA port. The board
doesn't expose the first port but somehow SStatus reports link online
while failing SRST protocol leading to repeated probe failures and
thus long boot delay.
Because the BIOS doesn't carry any identifying DMI information, the
port can't be blacklisted safely. Fortunately, the controller does
have subsystem vendor and ID set. It's unclear whether the subsystem
IDs are used only for the board but it can be safely worked around by
disabling SIDPR access and just using SRST works around the problem.
Even when the workaround is triggered on an unaffected board the only
side effect will be missing SCR access.

libata keeps a shadow copy of the ATA CTL register (which is write only),
and only writes to the hardware when the required value doesn't match
the shadow. However this copy wasn't being maintained when performing
reset functions. This could cause problems for the first operation after
a reset when the correct value might not be written to the CTL register.
This problem was observed when hotplugging a drive: the identify command
was being issued with interrupts enabled, when they should have been
disabled.

RFC5061 states:
Each adaptation layer that is defined that wishes
to use this parameter MUST specify an adaptation code point in an
appropriate RFC defining its use and meaning.
If the user has not set one - assume they don't want to sent the param
with a zero Adaptation Code Point.
Rationale - Currently the IANA defines zero as reserved - and
1 as the only valid value - so we consider zero to be unset - to save
adding a boolean to the socket structure.
Including this parameter unconditionally causes endpoints that do not
understand it to report errors unnecessarily.
