[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Markos Chandras <markos.chandras@xxxxxxxxxx>

This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit 6ca716f2e5571d25a3899c6c5c91ff72ea6d6f5e ]

A 64-bit build for Malta produces far too many build problems
when SMP/CPS is selected. Moreover, there is currently no 64-bit
product with SMP/CPS so we disable SMP/CPS when building for
64-bit until it is properly supported.
