[patch] cap code_gen_buffer_size on ia64

[Jes Sorensen <jes@xxxxxxx>]

Hi,

This one limits the code_gen_buffer_size on ia64, phys_mem_size/4
really gets out of hand when you boot say a 64GB guest.

Cheers,
Jes

Cap code_gen_buffer_size on ia64 - it quickly goes out of hand otherwise
when booting larger guests.
