From 4281da235e3de91bb8deae44bc6506336ceaa88a Mon Sep 17 00:00:00 2001 From: Ravi Bangoria Date: Mon, 29 Jan 2018 14:04:17 +0530 Subject: [PATCH] perf trace powerpc: Use generated syscall table This should speed up accessing new system calls introduced with the kernel rather than waiting for libaudit updates to include them. It also enables users to specify wildcards, for example, perf trace -e 'open*', just like was already possible on x86 and s390.
