Subject: Make cpu param to continue_hypercall_on_cpu() an unsigned integer.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~12365
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=e6baf56c8c02cd129dd1d043aab9183efaed2ef1;p=xen.git

Make cpu param to continue_hypercall_on_cpu() an unsigned integer.

Negative input makes no sense, and this makes the input range check
correct.
