[PATCH v2] Fix pointer cast for 32 bits arch
From: Peter Senna Tschudin
Date: Sun Apr 12 2015 - 05:32:28 EST
Sparse compalins about casting void * to u64 on i386.
Change the cast to resource_size_t.
Also update the gf_write64 function definition changing
the first argument type from unsigned long data to
resource_size_t.
