All the ia64 pvops code is now dead code since both xen and kvm support have been ripped out [0] [1]. Just that no one had troubled to rip this stuff out. The only useful remaining pieces were the old pvops docs but that was recently also generalized and moved out from ia64 [2]. This has been run time tested on an ia64 Madison system. [0]003f7de625"KVM: ia64: remove" since v3.19-rc1 [1]d52eefb47d"ia64/xen: Remove Xen support for ia64" since v3.14-rc1 [2] "virtual: Documentation: simplify and generalize paravirt_ops.txt" Signed-off-by: Luis R.
