[Qemu-devel] [PULL 1/3] Fix cacheline detection on FreeBSD/powerpc.

[Laurent Vivier <laurent@vivier.eu>]

From: Justin Hibbits <chmeeedalf@gmail.com>

machdep.cacheline_size is an integer, not a long.  Since PowerPC is
big-endian this causes sysctlbyname() to fill in the upper bits of the
argument, rather than the correct 'lower bits' of the word.  Specify the
correct type to fix this.
