percpu: cast percpu pointer in PERCPU_PTR() via unsigned long
Cast pointer from percpu address space to generic (kernel) address space
in PERCPU_PTR() macro via unsigned long intermediate cast [1]. This
intermediate cast is also required to avoid build failure when GCC's
strict named address space checks for x86 targets [2] are enabled.
Found by GCC's named address space checks.
