+Subject: [PATCH] Fix resolve when identical IPv4 and IPv6 hosts are defined in /etc/hosts
+
+This patch will fix a problem when the same host is defined with both IPv4 and
+IPv6 entries in /etc/hosts. Previous only the first of these host would work,
+as uClibc would read the /etc/hosts file from top to bottom, failing if the
+first hit did not match the IP type.
+
+Now uClibc will continue reading, even if the first correct entry name, but wrong IP
+type fails. Thus, allowing a second correct entry name with correct IP type
+will result in a name resolve.

+Subject: [Avr-gnu-toolchain] [uClibc PATCH] Load GOT pointer at the
+	beginning of .init and .fini
+
+I don't know why this seems to have worked before, but the .init and
+.fini sections typically consist of a bunch of mcalls using r6 as the
+base pointer. This can cause "interesting" behaviour when r6 hasn't
+been initialized to point to the GOT.
