usb: gadget: dummy_hcd: add 'is_high_speed' parameter
This patch adds a new module parameter to dummy_hcd
called is_high_speed.
When set to false the connected device will be forced
to operate in full-speed mode. By default, this parameter
is set to 'true'.

usb: gadget: dummy_hcd: add SuperSpeed support
This patch adds SS support to the dummy hcd module.
It may be used to test SS device when no (SS) HW is
available.
USB 3.0 hub includes 2 hubs - one HS and one SS. This
patch adds support for a SS root hub in the dummy_hcd
module.
A new module parameter was added: is_super_speed. When
set to true, a SS root hub will also be registered and
the connected device will be enumerated over the SS
root hub. The default of this parameter is false.

vlan: Fix the ingress VLAN_FLAG_REORDER_HDR check
Testing of VLAN_FLAG_REORDER_HDR does not belong in vlan_untag

vlan header accelleration.
As we remove the check from vlan_check_reorder_header
rename it vlan_reorder_header to keep the naming clean.
Fix up the skb->pkt_type early so we don't look at the packet
after adding the vlan tag, which guarantees we don't goof
and look at the wrong field.
Use a simple if statement instead of a complicated switch
statement to decided that we need to increment rx_stats

In kernel/irq/manage.c::irq_set_irq_wake() we call

irq_set_irq_wake() has lots of callers - I checked a few and I couldn't

Not all callers test the return value of irq_set_irq_wake(), but those

ipv4: Fix packet size calculation for raw IPsec packets in __ip_append_data
We assume that transhdrlen is positive on the first fragment
which is wrong for raw packets. So we don't add exthdrlen to the
packet size for raw packets. This leads to a reallocation on IPsec
because we have not enough headroom on the skb to place the IPsec
headers. This patch fixes this by adding exthdrlen to the packet
size whenever the send queue of the socket is empty. This issue was
introduced with git commit
1470ddf7 (inet: Remove explicit write
references to sk/inet in ip_append_data)

exec: delay address limit change until point of no return
Unconditionally changing the address limit to USER_DS and not restoring
it to its old value in the error path is wrong because it prevents us
using kernel memory on repeated calls to this function. This, in fact,
breaks the fallback of hard coded paths to the init program from being
ever successful if the first candidate fails to load.
With this patch applied switching to USER_DS is delayed until the point
of no return is reached which makes it possible to have a multi-arch
rootfs with one arch specific init binary for each of the (hard coded)
probed paths.
Since the address limit is already set to USER_DS when start_thread()
will be invoked, this redundancy can be safely removed.
