+Subject: eventfd.h: Use new "bits/" scheme for arch-specific flags
+
+As in timerfd.h, eventfd.h needs arch-specific definition files.
+alpha, mips and sparc needs separate file, all the other arch
+will use common definition.
+
+This problem is already fixed in glibc.
+
+Also sanitize and provide bits for hppa.
+Make sure not to install the new bits/eventfd unless eventfd support is
+enabled.
