num_sifr could go negative since acpi_pcc_get_sqty() returns -EINVAL
on error. Then it could bypass the sanity check (num_sifr > 255).
The subsequent call to kzalloc() would allocate a small buffer, leading
to a memory corruption.

We have several reports which says acer-wmi is loaded on ideapads
and register rfkill for wifi which can not be unblocked.
Since ideapad-laptop also register rfkill for wifi and it works
reliably, it will be fine acer-wmi is not going to register rfkill
for wifi once VPC2004 is found.
Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no
wifi rfkill capability, there are reports which says acer-wmi also
block wireless on Thinkpad E520/E420.

This patch adds support for some of the devices within a wide variety
of Fujitsu Tablet Computers, both convertibles and slates. Primarily
it allows for the automatic detection of the tablet/notebook mode for
convertible tablet pc's, and orientation for docked slates. It also
adds support for the application panel buttons usually found next to
the tablet screen, and docking station detection for slates.

An rfkill driver based on the fsaa1655g and fsam7440 drivers for
Fujitsu-Siemens Amilo A1655 and M7440 models found at:
http://sourceforge.net/projects/fsaa1655g/
http://sourceforge.net/projects/fsam7440/
This adds DMI matching, replaces the procfs files with rfkill devices,
and uses the proper functions to write to the i8042 safely.

tps65217_pmic_ops
Most callback functions implementation for tps65217_pmic_ldo234_ops and
tps65217_pmic_dcdc_ops are the same except the rid range checking.
This patch uses tps65217_pmic_ops for all DCDCx, LDO2, LDO3, and LDO4.
And rework tps65217_pmic_set_voltage to make it can be called for
DCDCx, LDO2, LDO3, and LDO4.

When the quirk HID_QUIRK_MULTITOUCH is present and when hid-multitouch
is loaded, let's pass the device to hid-multitouch even if it has
not been registered in hid-multitouch.
If any other driver wants to take precedence over hid-multitouch,
the usual way of adding it to hid_have_special_driver will work as
the quirk HID_QUIRK_MULTITOUCH won't be set by the generic hid layer.

LG multitouch panels, such as the one found in Dell ST2220T, has buggy
reports descriptors. With the previous implementation, it was impossible
to rely on the reports descriptors to determine how the different
touches are emitted from the device.
This patch changes the splitting of the different touches in the report
in a more robust way.

Use a more current kernel messaging style.
Convert a printk block to print_hex_dump.
Coalesce formats, align arguments.
Use %s, __func__ instead of embedding function names.
Some messages that were prefixed with <foo>_close are
now prefixed with <foo>_fini. Some ah4 and esp messages
are now not prefixed with "ip ".
The intent of this patch is to later add something like
#define pr_fmt(fmt) "IPv4: " fmt.
to standardize the output messages.
Text size is trivially reduced. (x86-32 allyesconfig)

With commit d6ddef9e641d(IPv6: Fix not join all-router mcast group
when forwarding set.) I check 'dev' after it's dereference that
leads to a Smatch complaint:
net/ipv6/addrconf.c:438 ipv6_add_dev()
warn: variable dereferenced before check 'dev' (see line 432)
net/ipv6/addrconf.c
431 /* protected by rtnl_lock */
432 rcu_assign_pointer(dev->ip6_ptr, ndev);
^^^^^^^^^^^^
Old dereference.
433
434 /* Join all-node multicast group */
435 ipv6_dev_mc_inc(dev, &in6addr_linklocal_allnodes);
436
437 /* Join all-router multicast group if forwarding is set
*/
438 if (ndev->cnf.forwarding && dev && (dev->flags &
IFF_MULTICAST))
^^^
Remove the check to avoid the complaint as 'dev' can't be NULL.

commit ea4fc0d619 (ipv4: Don't use rt->rt_{src,dst} in ip_queue_xmit())
added a serious regression on synflood handling.
Simon Kirby discovered a successful connection was delayed by 20 seconds
before being responsive.
In my tests, I discovered that xmit frames were lost, and needed ~4
retransmits and a socket dst rebuild before being really sent.
In case of syncookie initiated connection, we use a different path to
initialize the socket dst, and inet->cork.fl.u.ip4 is left cleared.
As ip_queue_xmit() now depends on inet flow being setup, fix this by
copying the temp flowi4 we use in cookie_v4_check().
