I know this patch is six months old, but I was wondering if anyone
knows of any plans to make these syscalls available to 64-bit apps?
We have a 32-bit app that uses __ARM_NR_compat_cacheflush, and we'd
like to port that app to 64-bit.  I'm just not sure how to start doing
that, since there don't appear to be any 64-bit ARM-specific syscalls.
