Two other changes are a fix in patch 1 which wasn't selecting ARCH_HAS_MEM_ENCRYPT for s390 spotted by Janani and removal of sme_active and sev_active symbol exports as suggested by Christoph Hellwig. These patches are applied on top of today's dma-mapping/for-next. I don't have a way to test SME, SEV, nor s390's PEF so the patches have only been build tested. Changelog Since v2: - Patch "x86,s390: Move ARCH_HAS_MEM_ENCRYPT definition to arch/Kconfig" - Added "select ARCH_HAS_MEM_ENCRYPT" to config S390. Suggested by Janani. - Patch "DMA mapping: Move SME handling to x86-specific files" - Split up into 3 new patches. Suggested by Christoph Hellwig. - Patch "swiotlb: Remove call to sme_active()" - New patch. - Patch "dma-mapping: Remove dma_check_mask()" - New patch. - Patch "x86,s390/mm: Move sme_active() and sme_me_mask to x86-specific header" - New patch. - Removed export of sme_active symbol. Suggested by Christoph Hellwig. - Patch "fs/core/vmcore: Move sev_active() reference to x86 arch code" - Removed export of sev_active symbol. Suggested by Christoph Hellwig. - Patch "s390/mm: Remove sev_active() function" - New patch. Since v1: - Patch "x86,s390: Move ARCH_HAS_MEM_ENCRYPT definition to arch/Kconfig" - Remove definition of ARCH_HAS_MEM_ENCRYPT from s390/Kconfig as well. - Reworded patch title and message a little bit. - Patch "DMA mapping: Move SME handling to x86-specific files" - Adapt s390's as well. - Remove dma_check_mask() from kernel/dma/mapping.c.
