MTD internal API presently uses 32-bit values to represent
device size.  This patch updates them to 64-bits but leaves
the external API unchanged.  Extending the external API
is a separate issue for several reasons.  First, no one
needs it at the moment.  Secondly, whether the implementation
is done with IOCTLs, sysfs or both is still debated.  Thirdly
external API changes require the internal API to be accepted
first.

Note that although the MTD API will be able to support 64-bit
device sizes, existing drivers do not and are not required
to do so, although NAND base has been updated.

In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
    	- printk message formats
    	- division and modulus of 64-bit values
    	- NAND base support
	- 32-bit local variables used by mtdpart and mtdconcat
	- naughtily assuming one structure maps to another
	in MEMERASE ioctl

Nandsim consumes ~2x more RAM than the density of simulated device.
It becomes critical if we need to simulate 256MB NAND and run stress tests
on it.

We investigated the reasons. nandsim allocates space for pages using kmalloc
function. The size of LP nand page is 2112 bytes.
kmalloc gets space from slab pools by chunks 2^n. So if we need to kmalloc
2112 bytes, 4096 bytes will be consumed by system.
The best way to avoid this issue would be using kmem_cache allocations. AFAIK
this mechanism specially designed to handle cases when arrays of allocations
are used.

Add a new module parameter 'cache_file' which causes nandsim
to use that file instead of memory to cache nand data.
Using a file allows the simulation of NAND that is bigger
than the available memory.

Some systems report SIS 5513 as both vendor/id and subvendor/id
string. In that case we can't distinguish the system by the id
svid/sdid and in fact the entry here breaks some boxes. At some

until then this trades a hang for some users with lower performance
