   4 Subject: scripts/checkstack.pl: Fix arm64 wrong or unknown architecture
   5
   6 [ Upstream commit 4f45d62a52297b10ded963412a158685647ecdec ]
   7
   8 The following error occurs for the `make ARCH=arm64 checkstack` case:
   9
  10 aarch64-linux-gnu-objdump -d vmlinux $(find . -name '*.ko') | \
  11 perl ./scripts/checkstack.pl arm64
  12 wrong or unknown architecture "arm64"
  13
  14 As suggested by Masahiro Yamada, fix the above error using regular
  15 expressions in the same way it was fixed for the `ARCH=x86` case via
  16 commit fda9f9903be6 ("scripts/checkstack.pl: automatically handle
  17 32-bit and 64-bit mode for ARCH=x86").
