Subject: [IA64] Don't warn for EOI-ing an edge triggered interrupt.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~14864
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/success/%22http:/www.example.com/cgi/success?a=commitdiff_plain;h=9370f313696f7f2f66bcf70243c3c45902636e01;p=xen.git

[IA64] Don't warn for EOI-ing an edge triggered interrupt.

Edge triggered interrupts don't need an EOI but EOI-ing them is harmless
according to the IOSAPIC documentation.  Do not emit a warning in such case.
