This reorganizes the vic.c code in anticipation of a second patch
to use struct vic_device as the data stored in set_irq_chip_data().

The code now has the following flow:

1) struct vic_device definition, static variables, and to_vic()
   moved to the start of the code.
2) common code (vic_init2)
3) vic power management callbacks
4) vic power management initialization/registration
5) irq_chip callbacks
6) vendor specific vic initialization
7) vic initialization

In addition the typo vik_init_st is fixed (vic_init_st).

There is no functional change with this patch.

This reverts commit ae1b22f6.

As Linus said in 982d007a: "There was something really messy about
cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it
carefully."

This breaks lguest for those configs, but we can fix that by emulating
if we have to.

In bbc_envctrl_init() we have to unlink the fan and temp instances

Holding locks over device_del -> kobject_del -> sysfs_deactivate can
cause deadlocks if those same locks are grabbed in sysfs show or store
methods.

The I model s_active count + completion as a sleeping read/write lock.
I describe to lockdep sysfs_get_active as a read_trylock,
sysfs_put_active as a read_unlock, and sysfs_deactivate as a
write_lock and write_unlock pair.  This seems to capture the essence
for purposes of finding deadlocks, and in my testing gives finds real
issues and ignores non-issues.

This brings us back to holding locks over kobject_del is a problem
that ideally we should find a way of addressing, but at least lockdep
can tell us about the problems instead of requiring developers to debug
rare strange system deadlocks, that happen when sysfs files are removed
while being written to.

The BKL is in this function because of the BKL pushdown (see commit

It is not needed here because the mutex_lock sonypi_device.lock provides
the necessary locking.

sonypi_misc_ioctl can be converted to unlocked ioctls since it relies on

We want to be sure that compiler fetches the limit variable only
once, so add helpers for fetching current and maximal resource

Add them to sched.h (instead of resource.h) due to circular dependency
