Subject: i386: add TRACE_IRQS_OFF for the exception 3 (int3)
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a790392faa3a6138b6e90d0fe320a2829652ce22;p=openwrt%2Fstaging%2Fblogic.git

i386: add TRACE_IRQS_OFF for the exception 3 (int3)

At this point interrupts are off, so let's inform the tracing
code of that fact before calling into C.
