The correct C99 type is (u)intptr_t.  In the kernel we only have
uintptr_t, with ACPI defining a local version of intptr_t.  I'd suggest
trying to stick to uintptr_t if we can, and if we really need a signed
version add intptr_t to the common headers - it can unconditionally be
typedef to long in Linux anyway.
