From: James Clarke Date: Sun, 18 Feb 2018 15:54:44 +0000 Subject: powerpc/lib/Makefile: Don't pull in quad.o for 32-bit kernels Origin: https://people.debian.org/~jrtc27/linux-ppc32/0002-powerpc-lib-Makefile-Don-t-pull-in-quad.o-for-32-bit.patch The functions exported by quad.o are only used when guarded by __powerpc64__ and so are unused on 32-bit kernels. Moreover, their implementations make use of instructions which will cause an illegal instruction error on 32-bit processors, and are not accepted by the assembler for SPE processors.
