The enter_monitor_world() function was trashing r0/r1/r2 registers and then was returning back to 'C'. The compiler might have used these registers in the C code. These new design prevents register corruptions. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@13060 6f19259b-4bc3-4df7-8a09-765794883524
