Error when inflating 6.5M deflated initrd image on ia64

[Jakub Jermář]

Looks like inflate only works for images up to certain size on ia64:

I added some debug prints that reveal that the source and destination areas of inflate actually overlap:

Looks like the not yet inflated part is overwritten by the already inflated part.

Fixed in mainline,1445.
