x86, signals: remove duplicated register setup code in ia32 signal delivery
Impact: cleanup, no functionality changed ia32_setup_rt_frame() has a duplicated code block labelled "Make -mregparm=3 work" for setting up the register parameters to the user-mode signal handler. This is harmless but ugly. Remove the redundant assignments. Signed-off-by: NMikael Pettersson <mikpe@it.uu.se> Signed-off-by: NIngo Molnar <mingo@elte.hu>
