[PATCH 5.4 242/270] include/asm-generic/vmlinux.lds.h: align ro_after_init

[Greg Kroah-Hartman]

From: Romain Naour <romain.naour@xxxxxxxxx>

commit 7f897acbe5d57995438c831670b7c400e9c0dc00 upstream.

Since the patch [1], building the kernel using a toolchain built with
binutils 2.33.1 prevents booting a sh4 system under Qemu.  Apply the patch
provided by Alan Modra [2] that fix alignment of rodata.
