MIPS: tools: Show result for loongson3-llsc-check It is better to show the result before loongson3-llsc-check exit, otherwise we can see nothing if the return status is EXIT_SUCCESS, it seems confusing. E.g. without this patch: [loongson@localhost tools]$ ./loongson3-llsc-check ../../../vmlinux [loongson@localhost tools]$ With this patch: [loongson@localhost tools]$ ./loongson3-llsc-check ../../../vmlinux loongson3-llsc-check returns success [loongson@localhost tools]$ Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

MIPS: Check Loongson3 LL/SC errata workaround correctness When Loongson3 LL/SC errata workarounds are enabled (ie. CONFIG_CPU_LOONGSON3_WORKAROUNDS=y) run a tool to scan through the compiled kernel & ensure that the workaround is applied correctly. That is, ensure that: - Every LL or LLD instruction is preceded by a sync instruction. - Any branches from within an LL/SC loop to outside of that loop target a sync instruction. Reasoning for these conditions can be found by reading the comment above the definition of __SYNC_loongson3_war in arch/mips/include/asm/sync.h. This tool will help ensure that we don't inadvertently introduce code paths that miss the required workarounds.
