The only reason that remains, to why the ARM cpuidle driver calls
cpuidle_register_driver(), is to avoid printing an error message in case
another driver already have been registered for the CPU. This seems a bit
silly, but more importantly, if that is a common scenario, perhaps we
should change cpuidle_register() accordingly instead.
In either case, let's consolidate the code, by converting to use
cpuidle_register|unregister(), which also avoids the unnecessary allocation
of the struct cpuidle_device.

There's no point to register the cpuidle driver for the current CPU, when
the initialization of the arch specific back-end data fails by returning
-ENXIO.
Instead, let's re-order the sequence to its original flow, by first trying
to initialize the back-end part and then act accordingly on the returned
error code. Additionally, let's print the error message, no matter of what
error code that was returned.

When an event is reported on a sub-directory and the parent inode has
a mark mask with FS_EVENT_ON_CHILD|FS_ISDIR, the event will be sent to
fsnotify() even if the event type is not in the parent mark mask
(e.g. FS_OPEN).
Further more, if that event happened on a mount or a filesystem with
a mount/sb mark that does have that event type in their mask, the "on
child" event will be reported on the mount/sb mark. That is not
desired, because user will get a duplicate event for the same action.
Note that the event reported on the victim inode is never merged with
the event reported on the parent inode, because of the check in
should_merge(): old_fsn->inode == new_fsn->inode.
Fix this by looking for a match of an actual event type (i.e. not just
FS_ISDIR) in parent's inode mark mask and by not reporting an "on child"
event to group if event type is only found on mount/sb marks.

Alpha has had c_ispeed and c_ospeed, but still set speeds in c_cflags
using arbitrary flags. Because BOTHER is not defined, the general
Linux code doesn't allow setting arbitrary baud rates, and because
CBAUDEX == 0, we can have an array overrun of the baud_rate[] table in
drivers/tty/tty_baudrate.c if (c_cflags & CBAUD) == 037.
Resolve both problems by #defining BOTHER to 037 on Alpha.
However, userspace still needs to know if setting BOTHER is actually
safe given legacy kernels (does anyone actually care about that on
Alpha anymore?), so enable the TCGETS2/TCSETS*2 ioctls on Alpha, even
though they use the same structure. Define struct termios2 just for
compatibility; it is the exact same structure as struct termios. In a
future patchset, this will be cleaned up so the uapi headers are

device drops packets into a black hole.
Jake adds support for software timestamping for packets sent over

skb_tx_timestamp() to the latest point possible, which is just prior to
notifying the hardware of the new Tx packet.

I tracked this down to put_mnt_ns running passing UMOUNT_SYNC and
disconnecting all of the mounts in a mount namespace. Fix this by
factoring drop_mounts out of drop_collected_mounts and passing
0 instead of UMOUNT_SYNC.
There are two possible behavior differences that result from this.
- No longer setting UMOUNT_SYNC will no longer set MNT_SYNC_UMOUNT on
the vfsmounts being unmounted. This effects the lazy rcu walk by
kicking the walk out of rcu mode and forcing it to be a non-lazy
walk.
- No longer disconnecting locked mounts will keep some mounts around
longer as they stay because the are locked to other mounts.
There are only two users of drop_collected mounts: audit_tree.c and
put_mnt_ns.
In audit_tree.c the mounts are private and there are no rcu lazy walks
only calls to iterate_mounts. So the changes should have no effect
except for a small timing effect as the connected mounts are disconnected.
In put_mnt_ns there may be references from process outside the mount
namespace to the mounts. So the mounts remaining connected will
be the bug fix that is needed. That rcu walks are allowed to continue
appears not to be a problem especially as the rcu walk change was about
an implementation detail not about semantics.

GSO tunneled packets are always segmented in software before they are
transmitted by a VLAN, even when the lower device can offload tunnel
encapsulation and VLAN together (i.e., some bits in NETIF_F_GSO_ENCAP_ALL
mask are set in the lower device 'vlan_features'). If we let VLANs have
the same tunnel offload capabilities as their lower device, throughput
can improve significantly when CPU is limited on the transmitter side.
- set NETIF_F_GSO_ENCAP_ALL bits in the VLAN 'hw_features', to ensure
that 'features' will have those bits zeroed only when the lower device
has no hardware support for tunnel encapsulation.
- for the same reason, copy GSO-related bits of 'hw_enc_features' from
lower device to VLAN, and ensure to update that value when the lower
device changes its features.
- set NETIF_F_HW_CSUM bit in the VLAN 'hw_enc_features' if 'real_dev'
is able to compute checksums at least for a kind of packets, like done
with commit 8403debeea ("vlan: Keep NETIF_F_HW_CSUM similar to other
software devices"). This avoids software segmentation due to mismatching
checksum capabilities between VLAN's 'features' and 'hw_enc_features'.
