Konstantin Belousov 2c66cccab7 Save and restore segment registers on amd64 when entering and leaving ... the kernel on amd64. Fill and read segment registers for mcontext and signals. Handle traps caused by restoration of the invalidated selectors. Implement user-mode creation and manipulation of the process-specific LDT descriptors for amd64, see sysarch(2). Implement support for TSS i/o port access permission bitmap for amd64. Context-switch LDT and TSS. Do not save and restore segment registers on the context switch, that is handled by kernel enter/leave trampolines now. Remove segment restore code from the signal trampolines for freebsd/amd64, freebsd/ia32 and linux/i386 for the same reason. Implement amd64-specific compat shims for sysarch. Linuxolator (temporary ?) switched to use gsbase for thread_area pointer. TODO: Currently, gdb is not adapted to show segment registers from struct reg. Also, no machine-depended ptrace command is added to set segment registers for debugged process.
