cpu_possible_map, which must not change after initialization, make this
slot == first_cpu(cpu_possible_map).

[PATCH] /dev/mem: validate mmap requests
Add a hook so architectures can validate /dev/mem mmap requests.
This is analogous to validation we already perform in the read/write
paths.
The identity mapping scheme used on ia64 requires that each 16MB or
64MB granule be accessed with exactly one attribute (write-back or
uncacheable). This avoids "attribute aliasing", which can cause a
machine check.
Sample problem scenario:
- Machine supports VGA, so it has uncacheable (UC) MMIO at 640K-768K
- efi_memmap_init() discards any write-back (WB) memory in the first granule
- Application (e.g., "hwinfo") mmaps /dev/mem, offset 0
- hwinfo receives UC mapping (the default, since memmap says "no WB here")
- Machine check abort (on chipsets that don't support UC access to WB
memory, e.g., sx1000)
In the scenario above, the only choices are
- Use WB for hwinfo mmap. Can't do this because it causes attribute
aliasing with the UC mapping for the VGA MMIO space.
- Use UC for hwinfo mmap. Can't do this because the chipset may not
support UC for that region.
- Disallow the hwinfo mmap with -EINVAL. That's what this patch does.

This creates a new function, cciss_interrupt_mode called from
cciss_pci_init. This function determines what type of interrupt vector to
use, i.e., MSI, MSI-X, or IO-APIC.
One noticeable difference is changing the interrupt field of the controller
struct to an array of 4 unsigned ints. The Smart Array HW is capable of
generating 4 distinct interrupts depending on the transport method in use
during operation. These are:
#define DOORBELL_INT 0
Used to notify the contoller of configuration updates. We only use
this feature when in polling mode.
#define PERF_MODE_INT 0
Used when the controller is in Performant Mode.
#define SIMPLE_MODE_INT 2
Used when the controller is in Simple Mode (current Linux implementation).
#define MEMQ_INT_MODE 3
Not used.
When using IO-APIC interrupts these 4 lines are OR'ed together so when any
one fires an interrupt an is generated. In MSI or MSI-X mode this hardware
OR'ing is ignored. We must register for our interrupt depending on what
mode the controller is running. For Linux we use SIMPLE_MODE_INT
exclusively at this time. Please consider this for inclusion.
