* | [IA64] evtchn_callback fix and cleanawilliam@xenbuild2.aw2006-12-185-21/+31
|/ | | | | | | | | | | | | | | 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.

* [NET]: Fix segmentation of linear packetskfraser@localhost.localdomain2006-12-151-5/+4
| | | | | | | | | | | | | | | | skb_segment fails to segment linear packets correctly because it tries to write all linear parts of the original skb into each segment. This will always panic as each segment only contains enough space for one MSS. This was not detected earlier because linear packets should be rare for GSO. In fact it still remains to be seen what exactly created the linear packets that triggered this bug. Basically the only time this should happen is if someone enables GSO emulation on an interface that does not support SG.

| | | | | | | | | | | | | | | | | | | | | | After being offline for a long time, the softlockup watchdog triggers a BUG() on our faces. This is expected, as in fact, we spent more than a fixed 10*HZ amount of time without touching the watchdog. However, by inspecting the contents of stolen inside timer irq handler, we can gain awareness of the fact, and do better than that. Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com>
