It seems that you are including kernel headers directly in your userspace 
code. Don't do that. Types defined in kernel headers conflict with types 
defined in your toolchain's kernel headers. Instead, just use the headers that 
are part of your toolchain, which in turn include kernel headers that your 
toolchain was built with.
