Patch imlements full LDT handling in SKAS:
* UML holds it's own LDT table, used to deliver data on
modify_ldt(READ)
* UML disables the default_ldt, inherited from the host (SKAS3)
or resets LDT entries, set by host's clib and inherited in
SKAS0
* A new global variable skas_needs_stub is inserted, that
can be used to decide, whether stub-pages must be supported
or not.
* Uses the syscall-stub to replace missing PTRACE_LDT (therefore,
write_ldt_entry needs to be modified)
Two complaints against this patch (to be fixed afterwards, so I'm not CC'ing akpm):
*) It reverts my cleanup and consolidation of ldt.c wrt. SKAS vs TT.
Or at least so I think (I must still give a proper look afterwards, and I'll post patches). Actually it seems that this is done on purpose, but I don't agree too much on this. I will see.
