Subject: [9fans] compiling xen3 with more recent pc kernel
Topicbox-Message-UUID: 5a0df8b8-ead9-11e9-9d60-3106f5b1d025

i had to make the following changes to the kernel for xen3 to match up
to recent labs pc kernel and to compile successfully.  can anyone verify
the changes are correct?  (i could to a smoke test on EC2, but don't
feel adventurous at the moment)

thanks,
