Subject: [PATCH v3 0/7] 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 SEV-ES guest
support. Changes to the previous version are:

	- Removed the patches already merged
	- Added a new fix to map the EFI MOKVar table encrypted
	- Disabled IRQs when GHCB is active
	- Relaxed state tracking by using irqentry_enter()/exit
	  instead of irqentry_nmi_enter()/exit()
	- Changed error reporting from insn_fetch_from_user*() as
	  requested by Boris

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

Thanks,

	Joerg

Joerg Roedel (6):
  x86/sev-es: Fix error message in runtime #VC handler
  x86/sev-es: Disable IRQs while GHCB is active
  x86/sev-es: Run #VC handler in plain IRQ state
  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

Tom Lendacky (1):
  x86/ioremap: Map efi_mem_reserve() memory as encrypted for SEV
