* kvm-arm64/pkvm_vm_handle: : pKVM VM handle allocation fixes, courtesy of Fuad Tabba. : : From the cover letter (20250909072437.4110547-1-tabba@google.com): : : "In pKVM, this handle is allocated when the VM is initialized at the : hypervisor, which is on the first vCPU run. However, the host starts : initializing the VM and setting up its data structures earlier. MMU : notifiers for the VMs are also registered before VM initialization at : the hypervisor, and rely on the handle to identify the VM. : : Therefore, there is a potential gap between when the VM is (partially) : setup at the host, but still without a valid pKVM handle to identify it : when communicating with the hypervisor." KVM: arm64: Reserve pKVM handle during pkvm_init_host_vm() KVM: arm64: Introduce separate hypercalls for pKVM VM reservation and initialization KVM: arm64: Consolidate pKVM hypervisor VM initialization logic KVM: arm64: Separate allocation and insertion of pKVM VM table entries KVM: arm64: Decouple hyp VM creation state from its handle KVM: arm64: Clarify comments to distinguish pKVM mode from protected VMs KVM: arm64: Rename 'host_kvm' to 'kvm' in pKVM host code KVM: arm64: Rename pkvm.enabled to pkvm.is_protected KVM: arm64: Add build-time check for duplicate DECLARE_REG use Signed-off-by: Marc Zyngier <maz@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
