This commit was manufactured to restore the state of the 5.3-RELEASE image.

1. Add macro DTV_OFFSET to calculate dtv offset in tcb.

2. Export symbols needed by debugger.

Add TLS support for i386 and amd64.

Save context in kernel fashion, so it can be restored by

2004-07-31T14:18:26+00:00

kse_switchin syscall.

Remove unused field.

Macro optimize, this increases context switch speed about 2% on my

2004-07-31T01:53:21+00:00

athlon64 machine.

Call kse_switchin to switch context when being debugged.

Avoid clobbering the red zone when running on the new context's stack in

2004-06-07T21:25:16+00:00

_amd64_restore_context().

Apply a second fix for stack alignment with libkse. This time, enter the

2003-12-05T01:41:43+00:00

UTS with the stack correctly aligned.  Also, while here, use an indirect
jump rather than the pushq/ret hack.

This fixes threaded apps that use floating point for me, although
it hasn't solved all the problems.  It is an improvement though.
Preservation of the 128 byte red zone hasn't been resolved yet.

Approved by:  re (scottl)

Use amd64_set_fsbase() instead of calling sysarch() directly.
