This series adds SEV-SNP support for unaccepted memory to the patch series
titled:

  [PATCHv7 00/14] mm, x86/cc: Implement support for unaccepted memory

Currently, when changing the state of a page under SNP, the page state
change structure is kmalloc()'d. This lead to hangs during boot when
accepting memory because the allocation can trigger the need to accept
more memory. So this series consists of two patches:

  - A pre-patch to switch from a kmalloc()'d page state change structure
    to a per-CPU page state change structure.

  - SNP support for unaccepted memory.

The series is based off of and tested against Kirill Shutemov's tree:
