Building 32-bit threw a warning on kASLR enabled builds: arch/x86/boot/compressed/aslr.c: In function ‘mem_avoid_overlap’: arch/x86/boot/compressed/aslr.c:198:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] avoid.start = (u64)ptr; ^ This fixes the warning; unsigned long should have been used here.
