From 9df225e9f8666777be42374c590df3bfafc62936 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Mon, 7 Nov 2016 22:28:21 -0800 Subject: [PATCH] powerpc: Fix exception vector build with 2.23 era binutils The changes to use gas sections for constructing the exception vectors causes a build break when using binutils 2.23: arch/powerpc/kernel/exceptions-64s.S:770: Error: operand out of range (0xffffffffffff8100 is not between 0x0000000000000000 and 0x000000000000ffff) And so on. Reported by Hugh with binutils-2.23.2-8.1.4.ppc64 from openSUSE 13.1 and also Naveen & Denis using 2.23.52.0.1-26.el7 from RHEL 7. Strangely binutils 2.22 (what I test with) is not affected. This is caused by the use of @l in LOAD_HANDLER(). The @l was only recently added in commit de04ba95ec71 ("powerpc/pseries: Remove unnecessary syscall trampoline"). Luckily the gas section changes split out the LOAD_SYSCALL_HANDLER() macro, which means we actually *don't* need to use @l in LOAD_HANDLER() any more, only in LOAD_SYSCALL_HANDLER(). So drop the @l from LOAD_HANDLER().
