Merge branch 'stable/for-linus-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb
Pull swiotlb fixlet from Konrad Rzeszutek Wilk:
"Enable the SWIOTLB under 32-bit PAE kernels.
Nowadays most distros enable this due to CONFIG_HYPERVISOR|XEN=y which
select SWIOTLB. But for those that are not interested in
virtualization and wanting to use 32-bit PAE kernels and wanting to
have working DMA operations - this configures it for them"
* 'stable/for-linus-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb:
