Revert "[PATCH] i386: export: memory more than 4G through /proc/iomem"
This reverts commit 10dbe196a8da6b3196881269c6639c0ec11c36cb.
The resource struct is still 32-bit, so trying to save a 64-bit memory
size there obviously won't work.
When we merge the 64-bit resource series, we can re-enable this.
Thanks to Sachin Sant and Maneesh Soni for debugging
