Subject: xen: SWIOTLB is only used on x86
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e8b404d99369ba3e6ec3259a4ea14bf1c18283f3;p=linux-beck.git

xen: SWIOTLB is only used on x86

Enabling SWIOTLB_XEN on ARM results in build errors because the
underlying SWIOTLB is only available on X86:

drivers/xen/swiotlb-xen.c: In function 'is_xen_swiotlb_buffer':
drivers/xen/swiotlb-xen.c:105:2: error: implicit declaration of function 'mfn_to_local_pfn
