Subject: [PATCH AUTOSEL 4.14 10/37] perf probe powerpc: Ignore SyS symbols irrespective of endianness
Date: Mon, 1 Oct 2018 00:38:59 +0000	[thread overview]
Message-ID: <20181001003850.147107-10-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20181001003850.147107-1-alexander.levin@microsoft.com>

From: Sandipan Das <sandipan@linux.ibm.com>

[ Upstream commit fa694160cca6dbba17c57dc7efec5f93feaf8795 ]

This makes sure that the SyS symbols are ignored for any powerpc system,
not just the big endian ones.
