Subject: sh: Provide an __sdivsi3_2 export for sh64.
X-Git-Tag: firefly_0821_release~13982^2~41^2~48
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1031a3a57ed76f5cb8754a89ddb22f3d9ebe8861;p=firefly-linux-kernel-4.4.55.git

sh: Provide an __sdivsi3_2 export for sh64.

Newer code paths that are heavier in 64-bit math manage to get this
generated by newer compilers, provide a definition and export
accordingly. This is trivially wrapped around the existing __sdivsi3
code.
