This patch fixes exception handling in RESTORE_ALL macro on returing
to user space. Incorrect values in %ds/%es can lead to incorrect 
behaivour and iret to kernel space address. This patch moves
exception handler from .fixup section to .entry.text and makes it
to be between int80_ret_start_marker/int80_ret_end_marker markers.

P.S. These 4GB split patches are against modified 2.6.8.1 kernel, but 
should be appliable to last Fedora kernels
