LDTSTOP may need to SB to help.


When trying to change cpu fid, CPU need LDTSTOP to make the FID change
effective.  enable_fid_change_on_sb will enable ldtstop on sb.


Current Amd8111 support code already have enable_fid_change_on_sb in the
public tree.


Serverworks ht1000 need to call ldtstop explicitly to make fid change
effective. I will check in the code after the new cpu is released.


The problem the ck804 has problem with ldtstop. We have to use some
other way to make it effective...
