[Xen-ia64-devel] Transparent virtualization and serial port.

Hi,

using this small patch:

     fp_offset = IO_SPACE_SPARSE_ENCODING(fp) & PAGE_MASK;
     lp_offset = PAGE_ALIGN(IO_SPACE_SPARSE_ENCODING(lp));


I was able to use linux compiled with serial port and xencons enabled.
This patch is a real kludge but if it is worth we can try to correctly disable 
serial port for xen console.
