From: Jan Beulich Date: Thu, 4 Jul 2013 08:25:31 +0000 (+0200) Subject: x86: drop MAX_VECTOR definition X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~6667 X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=966e77e9d6855274954d2d38eca2393121da477d;p=xen.git x86: drop MAX_VECTOR definition .. in favor of NR_VECTORS, as being redundant and as the latter is correct in terms of its naming, while the former is off by one.
