Subject: x86 hvm: Use 'x' as parameter name for macros converting between
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~13629
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=3e4d0322b7e4e72cda643d0baa4df2828beb6882;p=xen.git

x86 hvm: Use 'x' as parameter name for macros converting between
{vcpu,domain} and {vlapic,vpic,vrtc,hpet}. Completely avoids
accidental aliasing.
