But for UP (and possibly MP), If a timer interrupt (or IPI for SMP) fires in this small window of LDREX and STREX, Exception handler executes possibly variations cpu context and returns to the new job, nevertheless the stunning section is available in now, it executes 'CLREX' and for this reason taking away any distinctive lock held by preceding thread. So how improved is working with LDREX and STREX than LDR and STR for atomicity over a UP program ?
