ARC: entry.S: [arcompact] simplify SWITCH_TO_KERNEL_STK Previously this macro was overloaded with stack switching, saving SP at right slot in pt_regs, saving/setup of r25 and setting SP baseline to where pt_regs->sp is saved (vs. bottom of pt_regs) Now it only does SP switch, and leaves SP pointing to bottom of pt_regs. r25 saving is no longer done here to allow for future reordering of regfile in pt_regs w/o touching this macro Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
