Subject: [PATCH v4 0/6] x86/sev-es: Fixes for SEV-ES Guest Support

From: Joerg Roedel <jroedel@...e.de>

Hi,

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

	- Removed first patch which is now in tip/x86/urgent already
	- Removed patch "x86/sev-es: Run #VC handler in plain IRQ state"
	  and replaced it with
	  "x86/sev-es: Split up runtime #VC handler for correct state tracking"
	  as per suggestion from PeterZ

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

Thanks,

	Joerg

  x86/sev-es: Fix error message in runtime #VC handler
  x86/sev-es: Disable IRQs while GHCB is active
  x86/sev-es: Split up runtime #VC handler for correct state tracking
  x86/insn-eval: Make 0 a valid RIP for insn_get_effective_ip()
  x86/insn: Extend error reporting from
    insn_fetch_from_user[_inatomic]()
  x86/sev-es: Propagate #GP if getting linear instruction address failed
