This patch introduces cpu_set_fpuc() function, which changes fpuc field of the CPU state and calls update_fp_status() function. These calls update status of softfloat library and prevent bugs caused by non-coherent rounding settings of the FPU and softfloat. v2 changes: * Added missed calls and intoduced setter function (as suggested by TeLeMan) Reviewed-by: NTeLeMan <geleman@gmail.com> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NPavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru>

With the next patch, these need to be correct or VM86 tasks have the wrong CPL. The flags are basically what the Intel VMX documentation say is mandatory for entry into a VM86 guest. For consistency, SMM ought to have the same flags except with CPL=0. Tested-by: NKevin O'Connor <kevin@koconnor.net> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

This avoids polluting the global namespace with a non-prefixed macro and makes it obvious in the call sites that we return. Semi-automatic conversion using, e.g., sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c followed by manual tweaking for sparc's GET_REGA() and Coding Style.
