/*
* The C99 types uintXX_t that are usually defined in 'stdint.h' are not as
* unambiguous on ARM as you would expect. For the types below, there is a
* difference on ARM between GCC built for bare metal ARM, GCC built for glibc
* and the kernel itself, which results in build errors if you try to build with
* -ffreestanding and include 'stdint.h' (such as when you include 'arm_neon.h'
* in order to use NEON intrinsics)
*
* As the typedefs for these types in 'stdint.h' are based on builtin defines
* supplied by GCC, we can tweak these to align with the kernel's idea of those
* types, so 'linux/types.h' and 'stdint.h' can be safely included from the same
* source file (provided that -ffreestanding is used).
*
* int32_t uint32_t uintptr_t
* bare metal GCC long unsigned long unsigned int
* glibc GCC int unsigned int unsigned int
* kernel int unsigned int unsigned long
