It has some restrictions:

BDIs.

That INT_A may be INT_A from their (motherboard) point of view, but

This patch backports from 2.6.19 a fix to a 2.6.18 regression.
Like for PTRACE_OLDSETOPTIONS, we should fix PTRACE_[GS]ET_THREAD_AREA. This had

This was tested with UML/32bit as API consumer, both before and after this
patch.
