Subject: MIPS: Enable entries for SIGSYS in struct siginfo.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=51d139b1e481955b7bdd0c8d05d97cf2eb1f5be1;p=openwrt%2Fstaging%2Fblogic.git

MIPS: Enable entries for SIGSYS in struct siginfo.

This is necessary because MIPS doesn't use HAVE_ARCH_SIGINFO_T for
historical reasons.
