Ah yes, there it is, applied twice:

	 44 #if OS(LINUX) && defined(MADV_FREE)
	 45 // Added in Linux 4.5, but it breaks the sandbox.
	 46 #undef MADV_FREE
	 47 #endif
	 48 
	 49 #if OS(LINUX) && defined(MADV_FREE)
	 50 // Added in Linux 4.5, but we don't want to depend on 4.5 at runtime
	 51 #undef MADV_FREE
	 52 #endif
