Running shellcheck on syscalltbl.sh generates below warning:
In ./tools/perf/arch/x86/entry/syscalls/syscalltbl.sh line 27:
while read nr abi name entry compat; do
^-^ SC2034 (warning): abi appears unused. Verify use (or export if used externally).
^----^ SC2034 (warning): compat appears unused. Verify use (or export if used externally).
These variables are intentionally unused since they are needed to parse
through the output. Use "_" as a prefix for these throw away variables.
