I have struck a few problems compiling latest git (as of a few hours
ago). Some of the problems are due to the sanitization of kernel
headers, where it seems some openvz definitions have escaped out of
the #ifdef __KERNEL__ clause. Patch for those:

However, now I'm stuck at this one:

ERROR: "sys_open" [kernel/cpt/vzrst.ko] undefined!
ERROR: "sys_open" [kernel/cpt/vzcpt.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
+ exit 1

I'd really like some help.

this seems to have been fixed recently, and now checkpointing
compiles on amd64 (doesn't seem to work yet though:)
