[PATCH v3 0/6] Remove x86-specific code from generic headers

Hello,

This version is mostly about splitting up patch 2/3 into three separate
patches, as suggested by Christoph Hellwig. 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.
