+Subject: [PATCH xserver] xfree86: Inline xf86{Read,Write}Mmio{8,16,32} on
+ alpha
+
+In commit 9db2af6f757e (xfree86: Remove xf86{Map,Unmap}VidMem) we
+somehow stopped exporting xf86{Read,Write}Mmio{8,16,32}. Since the
+function pointer indirection was intended to support dense vs sparse and
+sparse support is now gone, we can just make the functions static inline
+in compiler.h and avoid all of this.
+
+Bugzilla: https://bugs.gentoo.org/548906
