Merge tag 'x86_sev_for_v6.11_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 SEV updates from Borislav Petkov: - Add support for running the kernel in a SEV-SNP guest, over a Secure VM Service Module (SVSM). When running over a SVSM, different services can run at different protection levels, apart from the guest OS but still within the secure SNP environment. They can provide services to the guest, like a vTPM, for example. This series adds the required facilities to interface with such a SVSM module. - The usual fixlets, refactoring and cleanups [ And as always: "SEV" is AMD's "Secure Encrypted Virtualization". I can't be the only one who gets all the newer x86 TLA's confused, can I? - Linus ] * tag 'x86_sev_for_v6.11_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: Documentation/ABI/configfs-tsm: Fix an unexpected indentation silly x86/sev: Do RMP memory coverage check after max_pfn has been set x86/sev: Move SEV compilation units virt: sev-guest: Mark driver struct with __refdata to prevent section mismatch x86/sev: Allow non-VMPL0 execution when an SVSM is present x86/sev: Extend the config-fs attestation support for an SVSM x86/sev: Take advantage of configfs visibility support in TSM fs/configfs: Add a callback to determine attribute visibility sev-guest: configfs-tsm: Allow the privlevel_floor attribute to be updated virt: sev-guest: Choose the VMPCK key based on executing VMPL x86/sev: Provide guest VMPL level to userspace x86/sev: Provide SVSM discovery support x86/sev: Use the SVSM to create a vCPU when not in VMPL0 x86/sev: Perform PVALIDATE using the SVSM when not at VMPL0 x86/sev: Use kernel provided SVSM Calling Areas x86/sev: Check for the presence of an SVSM in the SNP secrets page x86/irqflags: Provide native versions of the local_irq_save()/restore()
