Hip hop producer Mally Mall played a key role in settling Drake and Chris Brown's longstanding feud ... because he brought them together at his house in Las Vegas.
When we caught up with Mally in L.A. ... he said "the past is the past" for Breezy and Drizzy, and that Rihanna's name never came up during their recording sessions in Mally's home studio.
They've come a long way from 2 years ago when they destroyed W.i.P. Nightclub in New York in an all-out brawl over RiRi -- but Mally says ... "We squashed the beef."
Mally -- who's new release "Mally's World" drops next month -- did have one comment about Rihanna "acting like a jump off."
