The current insert_vm_table_entry() function performs two actions at once: it finds a free slot in the pKVM VM table and populates it with the pkvm_hyp_vm pointer. Refactor this function as a preparatory step for future work that will require reserving a VM slot and its corresponding handle earlier in the VM lifecycle, before the pkvm_hyp_vm structure is initialized and ready to be inserted. Split the function into a two-phase process: - A new allocate_vm_table_entry() function finds an empty slot, marks it as reserved with a RESERVED_ENTRY placeholder, and returns a handle derived from the slot's index. - The insert_vm_table_entry() function is repurposed to take the handle, validate that the corresponding slot is in the reserved state, and then populate it with the pkvm_hyp_vm pointer.

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.
