From: Maciej W. Rozycki Date: Fri, 3 Apr 2015 22:32:22 +0000 (+0100) Subject: MIPS: DEC: Do not set up the FPU interrupt if no FPU X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5ffd7c8b13643f4bb6e35b2eababf5336d5e8353;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git MIPS: DEC: Do not set up the FPU interrupt if no FPU Following the arrangement for processors that wire FPU exceptions to the FPE CPU exception handle the case where no FPU is in use -- which for DECstation systems will only ever happen when the "nofpu" kernel option has been used -- do not register the FPU interrupt in such a case either.
