Very odd. Nothing around this ought to be conditional and
xc_hvm_param_get works for everything else on ARM it seems.

Plus xc_get_hvm_param and xc_hvm_param_get are defined right next to
each other with no cpp magic anywhere near them.

My guess would be that the compiler is picking up some system version of
xenctrl.h instead of the one in tools/libxc. It really shouldn't be
though!

I cross built your patch on current staging and it was OK for me, so I
guess it is something strange in your chroot. I think I'd start from
"find $chroot -name xenctrl.h" and work from there.

But, given that it works for me and it looks sensible I don't mind if
you send it untested on ARM this time around.

Ian.
