Hi,

here is the next revision of my pending fixes for Linux' SEV-ES
support. Changes to the previous version are:

- Updated patch 2 and implemented wrappers around
sev_es_get/put_ghcb() which will disable/enable IRQs when
needed.
- Updated patch 3 to now call the from_user and from_kernel
functions of the VC handler directly from entry-asm.

The previous version can be found here:

https://lore.kernel.org/lkml/20210610091141.30322-1-joro@8bytes.org/

Changes are based on tip/x86/urgent. Please review.

Thanks,

Joerg
