Chuck reports that the recent fix from Andi to oprofile
6c977aad introduces a double free.  Each
cpu's cpu_msrs is setup to point to cpu 0's, which causes free_msrs to free
cpu 0's pointers for_each_possible_cpu.  Rather than copy the pointers, do
a deep copy instead.

I have made a tool to parse the kernel that does not pre-process the
source.  That means that my parser tries to parse all the code, including
code in the #else branch or code that is not often compiled because the
driver is not very used (or not used at all).  So, my parser sometimes
reports parse error not originally detected by gcc.  Here is my (first)
patch.

The Via VT3351 APIC does not play well with MSI and unleashes a flood
of APIC errors when MSI is used to deliver interrupts.  The problem
was recently exposed when the atl1 network device driver, which enables
MSI by default, stimulated APIC errors on an Asus M2V mainboard, which
employs the Via VT3351.
See http://bugzilla.kernel.org/show_bug.cgi?id=8472 for additional

Wolfgang gets:

 PCI: Cannot allocate resource region 0 of device 0000:00:04.0
 PCI: Error while updating region 0000:00:04.0/0 (a8008000 != fec08000)

Note that the BAR seems to have high address bits hardwired to fec00000.
And device 0000:00:04.0 is

 00:04.0 System peripheral: Siemens Nixdorf AG FSC Multiprocessor Interrupt Controller (rev 02)

I'd guess that when we try to reassign this resource, PCI interrupts might
just stop working. This could explain SCSI timeouts and other weird things.
