[Xen-devel] multicalls.c warning in xen_mc_flush

[William Dauchy <wdauchy@xxxxxxxxx>]

Hello,

I'm getting a call trace when booting a dom0 v3.3.7 (x86_32) under xen 4.1.2.
It is about multicalls.c:129. I tried with MC_DEBUG = 1 but it appears
that b->mcidx = 1 when getting this call trace.
Does anybody have any clue?
