From: "George G. Davis" <george_davis@xxxxxxxxxx>
Subject: scripts/checkstack.pl: fix arm64 wrong or unknown architecture
The following error occurs for the `make ARCH=arm64 checkstack` case:
aarch64-linux-gnu-objdump -d vmlinux $(find . -name '*.ko') | \
perl ./scripts/checkstack.pl arm64
wrong or unknown architecture "arm64"
As suggested by Masahiro Yamada, fix the above error using regular
expressions in the same way it was fixed for the `ARCH=x86` case via
fda9f9903be6 ("scripts/checkstack.pl: automatically handle 32-bit and
64-bit mode for ARCH=x86").
