Casting to u32 works well on 32-bit builds, but causes problem when
compiled on 64-bit machines. Switch it to cast to "unsigned long", so
that it would have appropriate width in both cases.

ev/mem's size to U64_MAX, that alone should disable any checks since
U64_MAX is also FILE_SIZE_STREAM and validation code in lseek() is:
if (f->size != FILE_SIZE_STREAM && (pos < 0 || pos > f->size))
goto out;
Sascha, is this the direction you want to go? Should we rename

Casting to u32 works well on 32-bit builds, but causes problem when
compiled on 64-bit machines. Switch it to cast to "unsigned long", so
that it would have appropriate width in both cases.
While at it, replace explicit casts to void * with IOMEM.
