Subject: [SPARC64]: Fix VIRQ enabling.
X-Git-Tag: v2.6.22-rc7~11^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1245088400c0e5f93b979356e578c9a8825b953a;p=linux-2.6

[SPARC64]: Fix VIRQ enabling.

We were doing the wrong call to turn them on, and also
when enabling we need to forcefully set the state to IDLE.
