I need to take this series via the powerpc tree because there is another fairly large powerpc specific series dependent on it. I think this series already has pretty much all the acks it needs, which almost never happens, amazing work! I'll put the series in a topic branch, just in case there's any bad conflicts and other folks want to merge it later on. I'll then merge the topic branch into my next, and so this series will be tested in linux-next that way. cheers > Changelog > > Since v3: > > - Patch "s390/mm: Remove sev_active() function" > - Preserve comment from sev_active() in force_dma_unencrypted(). > Suggested by Christoph Hellwig. > > Since v2: > > - Patch "x86,s390: Move ARCH_HAS_MEM_ENCRYPT definition to arch/Kconfig" > - Added "select ARCH_HAS_MEM_ENCRYPT" to config S390.
