[RHEL5.1][XEN][IA64] evtchn_callback fix and clean
Last modified: 2013-07-03 09:41:23 EDT
Description of problem:
Since we had changed to use event callback to deliver interrupts,
1. The pending_interruption is changed to pending_event.
2. get_ivr, set_tpr, get_trp and set_eoi are not used or only used
in the initialization phase. There is no need to write this code
in assembly. This code is deleted.
3. hyper_ssm_i needs to be rewritten to jump to entchn_callback_handler
instead of iva+0x3000 interrupt handler. I will do this later.
cset#13084 fixes the issues.
This request was evaluated by Red Hat Kernel Team for inclusion in a Red
