Commit 2479bfc9bc600 ("powerpc: Fix build by disabling attribute-alias
warning for SYSCALL_DEFINEx") forgot arch/powerpc/kernel/pci_32.c
Latest GCC version emit the following warnings
As arch/powerpc code is built with -Werror, this breaks build with
GCC 8.1
This patch inhibits this warning
In file included from arch/powerpc/kernel/pci_32.c:14:
