Message-Id: <20181017.120859.2268840244308635255.davem@davemloft.net> Date: Wed, 17 Oct 2018 12:08:59 -0700 (PDT) From: David Miller <davem@...emloft.net> To: acme@...hat.com CC: linux-kernel@...r.kernel.org Subject: [PATCH] perf: Set PLT entry/header sizes properly on Sparc. 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. Signed-off-by: David S.
