Subject: xtensa: reduce double exception literal reservation
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6bf28969f617f0131e94deb5476f4c45f43fd847;p=openwrt%2Fstaging%2Fblogic.git

xtensa: reduce double exception literal reservation

Double exception vector only needs 20 bytes of space for 5 literals, not
48. Reduce the reservation for double exception vector literals
accordingly. This fixes build for configurations with small user
exception vector size.
