+From e3647f5b6b52996bf30d0c2c1d1248e4182e1c1c Mon Sep 17 00:00:00 2001

+Date: Wed, 13 Nov 2019 13:36:10 +0100
+Subject: [PATCH] api: define __SNR_ppoll again
+
+Commit bf747eb21e428c2b3ead6ebcca27951b681963a0 accidentally removed the
+__SNR_ppoll definition. Add it back, using a PNR value if disabled in
+the kernel headers.
