| |
-stable review patch. If anyone has any objections, please let us know.
------------------ From: David Miller <davem@davemloft.net>
[SPARC64]: Fix quad-float multiply emulation.
Something is wrong with the 3-multiply (vs. 4-multiply) optimized version of _FP_MUL_MEAT_2_*(), so just use the slower version which actually computes correct values.
