Subject: [PATCH 0/2] x86/snp: Add kexec support
Date: Tue, 20 Feb 2024 01:18:10 +0000	[thread overview]
Message-ID: <cover.1708390906.git.ashish.kalra@amd.com> (raw)
In-Reply-To: <20240212104448.2589568-1-kirill.shutemov@linux.intel.com>

From: Ashish Kalra <ashish.kalra@amd.com>

The patchset adds bits and pieces to get kexec (and crashkernel) work on
SNP guest.

This patchset requires [1] for chained guest kexec to work correctly.

[1]: https://lore.kernel.org/lkml/20240219225451.787816-1-Ashish.Kalra@amd.com/

Ashish Kalra (2):
  x86/mm: Do not zap PMD entry mapping unaccepted memory table during
    kdump.
  x86/snp: Convert shared memory back to private on kexec
