+Subject: Bluetooth: Fix faulty expression for minimum encryption key size check
+
+From: Matias Karhumaa <matias.karhumaa@gmail.com>
+
+commit eca94432934fe5f141d084f2e36ee2c0e614cc04 upstream.
+
+Fix minimum encryption key size check so that HCI_MIN_ENC_KEY_SIZE is
+also allowed as stated in the comment.
+
+This bug caused connection problems with devices having maximum
+encryption key size of 7 octets (56-bit).
+
+Fixes: 693cd8ce3f88 ("Bluetooth: Fix regression with minimum encryption key size alignment")
+Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=203997

+Subject: um: Compile with modern headers
+
+From: Jason A. Donenfeld <Jason@zx2c4.com>
+
+commit 530ba6c7cb3c22435a4d26de47037bb6f86a5329 upstream.
+
+Recent libcs have gotten a bit more strict, so we actually need to
+include the right headers and use the right types. This enables UML to
+compile again.
