[uml-devel] Panic while core dumping in tt-mode

[Stroesser, B. <Bod...@fu...>]

Testing my extensions for vsyscall/sysenter I need to check the
presence of the vsyscall-page in the core. But in tt-mode the
kernel panics if core dump is started. In copy_fpu_fxsave_tt()
the line

  struct i387_fxsave_struct *fpu =3D SC_FXSR_ENV(PT_REGS_SC(regs));

sets fpu to 0x70, then memcpy() segfaults.
Maybe the reason is in the new signal-delivery?
