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 a24553dd02dc ("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().
