[PATCH 5.14 118/125] riscv: fix misalgned trap vector base address

[Greg Kroah-Hartman]

From: Chen Lu <181250012@xxxxxxxxxxxxxxxx>

commit 64a19591a2938b170aa736443d5d3bf4c51e1388 upstream.

The trap vector marked by label .Lsecondary_park must align on a
4-byte boundary, as the {m,s}tvec is defined to require 4-byte
alignment.
