uintptr_t which is a typdef for unsigned long is needed for creating pointers (32 or 64 bit depending on Core) from 32 bit variables storing the address. If a 32 bit variable (u32) is typecasted to a pointer (void *), compiler gives a warning in case size of pointer on the core is 64 bit.
The typdef has been moved from include/compiler.h to include/linux/types.h
