linux_compat: remove cpu_relax() define
The macro cpu_relax() is defined by several headers in different ways. arch/{arm,avr32,mips}/include/asm/processor.h defines it as follows: #define cpu_relax() barrier() On the other hand, include/linux/compat.h defines it as follows: #define cpu_relax() do {} while (0) If both headers are included from the same source file, the warning warning: "cpu_relax" redefined [enabled by default] is displayed. It effectively makes it impossible to include <linux/compat.h> from some sources. Drop the latter.
