Xen 4.5: revert dpci patches

Xen 4.5: revert dpci patches

[Konrad Rzeszutek Wilk]

Hey,

Two folks (Malcom, Sander) have reported issues with the dpci softirq code and
while I've an fix that fixes it, and this stage I am uncomfortable putting
it in Xen 4.5. As such I am going to revert from Xen 4.5 tree
(only) these patches:

104072f dpci: add 'masked' as a gate for hvm_dirq_assist to process
f6dd295 dpci: replace tasklet with softirq
aeeea48 dpci: move from an hvm_irq_dpci (and struct domain) to an hvm_dirq_dpci model

Which will make that code be as it was in Xen 4.4.

They (patches) are not going to be reverted in staging where
I will continue troubleshooting and fix it.

The proposed patch is http://lists.xen.org/archives/html/xen-devel/2015-01/msg01024.html
for those curious folks.

Ok i will test the 4.5-staging branch with the reverts as well this evening,
see if that doesn't turn up anything on my config.

Hi Konrad,

As far as my test goes, current staging-4.5 (with the reverts) also works fine.
