[PATCH 0/4] kvm: sev: Fix issues reported by Sashiko

[Jörg Rödel]

From: Joerg Roedel <joerg.roedel@xxxxxxx>

Hi,

On the post of my direct-VMSA patch-set Sashiko reported a few real
pre-existing issues in the SEV-SNP launch_update code. This patch-set
addresses three of them:

	* Fix user-triggerable WARN_ON on LAUNCH_UPDATE path.

	* Check that CPUID pages are writable before writing error
	  information to it.

	* Fix kunmap_local() order.

Please review.
