4.19-stable review patch. If anyone has any objections, please let me know.
------------------ [ 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. Signed-off-by: David S.
