Subject: Make event_pending() architecture-specific.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~16158^2~5^2~2
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/success//%22http:/www.example.com/cgi/success/?a=commitdiff_plain;h=89bbff5329afc3b05ccc14ef3cf733f35d8ea4d3;p=xen.git

Make event_pending() architecture-specific.
PowerPC needs this because the domain can directly modify the hardware's
"interrupts enabled" bit, and we don't want to patch Linux to replace
all those accesses to use evtchn_upcall_mask instead.
