+Subject: [PATCH] ARM64: Fix build break for RTL8187/RTL8192CU wifi
+
+These drivers use an ASM function from the base
+system to compute the ipv6 checksum.  These functions
+are not available on ARM64, probably because nobody
+has bother to write them.  The base system does have
+a generic "C" version, so a simple fix is to include
+the header to use the generic version on ARM64 only.
+
+A longer term solution would be to submit the necessary
+ASM function to the upstream source.
+
+With this change, these drivers now compile without
+any errors on ARM64.
