Hi all,

After merging the tomoyo tree, today's linux-next build (powerpc
ppc64_defconfig) produced these warnings:

drivers/scsi/mpt3sas/mpt3sas_scsih.c: In function 'scsih_suspend':
drivers/scsi/mpt3sas/mpt3sas_scsih.c:12412:9: note: '#pragma message: Please avoid flushing system-wide workqueues.'
