[PATCH] uml: fix missing x86_64 register definitions
The UML/x86_64 headers were missing ptrace support for some segment registers.
The underlying problem was that the x86_64 kernel uses user_regs_struct
rather than the ptrace register definitions in ptrace. This patch switches
UML/x86_64 to using user_regs_struct for its definitions of the host's
registers.
