Subject: [PATCH v5 0/6] x86/sev-es: Fixes for SEV-ES Guest Support
Date: Mon, 14 Jun 2021 15:53:21 +0200	[thread overview]
Message-ID: <20210614135327.9921-1-joro@8bytes.org> (raw)

From: Joerg Roedel <jroedel@suse.de>

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
