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 commita24553dd02
("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(). Fixes:57f266497d
