From 5209e5bfe5cab593476c3e7754e42c5e47ce36de Mon Sep 17 00:00:00 2001 From: Rick Edgecombe Date: Thu, 2 Apr 2026 00:32:05 -0600 Subject: [PATCH] x86/virt/tdx: Remove kexec docs Recent changes have removed the hard limitations for using kexec and TDX together. So remove the section in the TDX docs. Users on partial write erratums will need an updated TDX module to handle the rare edge cases. The docs do not currently provide any guidance on recommended TDX module versions, so don't keep a whole section around to document this interaction.
