Force irq migration path during cpu offline, is not using proper locks and
irq_chip mask/unmask routines.  This will result in some races(especially
the device generating the interrupt can see some inconsistent state,
resulting in issues like stuck irq,..).

Appended patch fixes the issue by taking proper lock and encapsulating
irq_chip set_affinity() with a mask() before and an unmask() after.

This fixes a MSI irq stuck issue reported by Darrick Wong.

There are several more general bugs in this area(irq migration in the
process context). For example,

 1. Possibility of missing edge triggered irq.
 2. Reliable method of migrating level triggered irq in the process context.

We plan to look and close these in the near future.

Eric says:
	In addition even with the fix from Suresh there is still at least one
	nasty hardware race in fixup_irqs().   However we exercise that code
	path rarely enough that we are unlikely to hit it in the real world,
	and that race seems to have existed since the code was merged.  And a
	fix for that is not coming soon as it is an open investigation area
	if we can fix irq migration to work outside of irq context or if
	we have to rework the requirements imposed by the generic cpu hotplug
	and layer on fixup_irqs().  So this may come up again.

usb_unlink_urb() is asynchronous, therefore an URB's buffer may not
be freed without waiting for the completion handler. This patch switches
to usb_kill_urb(), which is synchronous.

This fixes a bug which can cause corruption of the floating-point state
on return from a signal handler.  If we have a signal handler that has
used the floating-point registers, and it happens to context-switch to
another task while copying the interrupted floating-point state from the
user stack into the thread struct (e.g. because of a page fault, or
because it gets preempted), the context switch code will think that the
FP registers contain valid FP state that needs to be copied into the
thread_struct, and will thus overwrite the values that the signal return
code has put into the thread_struct.

This can occur because we clear the MSR bits that indicate the presence
of valid FP state after copying the state into the thread_struct.  To fix
this we just move the clearing of the MSR bits to before the copy.  A
similar potential problem also occurs with the Altivec state, and this
fixes that in the same way.

Consider the prototype for gettimeofday():
	int gettimofday(struct timeval *tv, struct timezone *tz);

Although it is valid to call with /either/ tv or tz being NULL, and
the C version of sys_gettimeofday() supports this, the current version
of gettimeofday() in the VDSO will SEGV if called with a NULL tv.

This adds a check for tv being NULL so that it doesn't SEGV.
