This patch updates the INTC code by moving all vectors,
groups and registers from struct intc_desc to struct
intc_hw_desc.
The idea is that INTC tables should go from using the
macro(s) DECLARE_INTC_DESC..() only to using struct
intc_desc with name and hw initialized using the macro
INTC_HW_DESC(). This move makes it easy to initialize
an extended struct intc_desc in the future.

The counters are now updated independently, from measuring the file,

ima_path_check() is called from nfsd and do_filp_open().
It also did not measure all files that should have been measured.

Add a clocksource suspend callback. This callback can be used by the
clocksource driver to shutdown and perform any kind of late suspend
activities even though the clocksource driver itself is a non-sysdev
driver.
One example where this is useful is to fix the sh_cmt.c platform driver
that today suspends using the platform bus and shuts down the clocksource
too early.
With this callback in place the sh_cmt driver will suspend using the
clocksource and clockevent hooks and leave the platform device pm
callbacks unused.

option is only allowed with SOCK_RAW sockets attached to ethernet
type devices.

This patch introduces the similar helpers as those already done for uc list.
However multicast lists are no list_head lists but "mademanually". The three
macros added by this patch will make the transition of mc_list to list_head
smooth in two steps:
1) convert all drivers to use these macros (with the original iterator of type
"struct dev_mc_list")
2) once all drivers are converted, convert list type and iterators to "struct
netdev_hw_addr" in one patch.
>From now on, drivers can (and should) use "netdev_for_each_mc_addr" to iterate
over the addresses with iterator of type "struct netdev_hw_addr". Also macros
"netdev_mc_count" and "netdev_mc_empty" to read list's length. This is the state
which should be reached in all drivers.

We cannot assume that because hwc->idx == assign[i], we can avoid
reprogramming the counter in hw_perf_enable().
The event may have been scheduled out and another event may have been
programmed into this counter. Thus, we need a more robust way of
verifying if the counter still contains config/data related to an event.
This patch adds a generation number to each counter on each cpu. Using
this mechanism we can verify reliabilty whether the content of a counter
corresponds to an event.

/sys/devices/platform/gpio-keys/switches [ro]
/sys/devices/platform/gpio-keys/disabled_keys [rw]

With these attributes, userland program can read which keys and
switches can be disabled and then disable/enable them as needed.
Keys and switches are exported as stringified bitmap of codes
(keycodes or switch codes). For example keys 15, 89, 100, 101,
102 are exported as: '15,89,100-102'.

disabled_switches - bitmap of currently disabled switches

In order to use macvlan with qemu and other tools that require
a tap file descriptor, the macvtap driver adds a small backend
with a character device with the same interface as the tun
driver, with a minimum set of features.
Macvtap interfaces are created in the same way as macvlan
interfaces using ip link, but the netif is just used as a
handle for configuration and accounting, while the data
goes through the chardev. Each macvtap interface has its
own character device, simplifying permission management
significantly over the generic tun/tap driver.

Still, it is necessary to distinguish whether the report in question should be

so that hid_output_raw_report() callback provides means to specify this
value so that it can be passed down to lower level hardware drivers (currently
