Subject: [MIPS] Update struct sigcontext member names
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1c0c1ae4f3d5057d091677d0ef7dbaeb28122ded;p=openwrt%2Fstaging%2Fblogic.git

[MIPS] Update struct sigcontext member names

Rename the 64-bit sc_hi and sc_lo arrays to use the same names
as the 32-bit struct sigcontext (sc_mdhi, sc_hi1, et cetera).
