Subject: [PATCH AUTOSEL 4.14 16/26] perf symbols: Set PLT entry/header sizes properly on Sparc
Date: Tue, 13 Nov 2018 00:51:40 -0500	[thread overview]
Message-ID: <20181113055150.78773-16-sashal@kernel.org> (raw)
In-Reply-To: <20181113055150.78773-1-sashal@kernel.org>

From: David Miller <davem@davemloft.net>

[ Upstream commit d6afa561e1471ccfdaf7191230c0c59a37e45a5b ]

Using the sh_entsize for both values isn't correct.  It happens to be
correct on x86...

For both 32-bit and 64-bit sparc, there are four PLT entries in the PLT
section.
