+Subject: [PATCH] aarch64: Fix a plthook crash on aarch64 with binutils2.35.1
+ and later versions
+
+plthook is always crashed in Ubuntu 20.10 aarch64, which uses binutils 2.35.1.
+Since the `plt_entsize` is not automatically set in this version, we have to
+explicitly set the value.
+
+This patch fixes the following problem.
+
+ $ uname -m
+ aarch64
+
+ $ cat /etc/os-release | grep PRETTY_NAME
+ PRETTY_NAME="Ubuntu 20.10"
+
+ $ gcc -pg tests/s-abc.c
+
+ $ uftrace record a.out
+ WARN: child terminated by signal: 7: Bus error
+
+Fixed: #1254
+
+Upstream-status: submitted [Sent to https://github.com/namhyung/uftrace/pull/1248]
