Subject: [XEN] Wrap compat XLAT_ macros in "do { } while (0)".
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~15358^2~28
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=9ed702329188d028ff588a5e0f4bd8956b31222d;p=xen.git

[XEN] Wrap compat XLAT_ macros in "do { } while (0)".
This unbreaks code like

    if ( !IS_COMPAT(dom) )
        memcpy();
    else
        XLAT_foo();
