Re: [Xen-devel] [PATCH] Make strace happy with xeno64.

CS is 0xE033 for 64bit apps on xeno64.

Xenolinux should be installing its own GDT with selectors at 0x23/0x33 and be using those. I think it already installs a suitable GDT, so probably simply a matter of modifying a few USER_CS macros somewhere.
