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.

We want to paravirtualize only __kernel_syscall_via_epc because it includes privileged instructions. Its paravirtualization increases its symbols size. On the other hand, each paravirtualized gate must have e symbols of same value and size to native's because the page is mapped to GATE_ADDR and GATE_ADDR + PERCPU_PAGE_SIZE and vmlinux is linked to those symbols. Later to have the same symbol size, we pads NOPs at the end of __kernel_syscall_via_epc. Move it after other functions to keep symbols of other functions have same values and sizes.
