...and remove struct vcpu_vmx's temporary __launched variable. Eliminating __launched is a bonus, the real motivation is to get to the point where the only reference to struct vcpu_vmx in the asm code is to vcpu.arch.regs, which will simplify moving the blob to a proper asm file. Note that also means this approach is deliberately different than what is used in nested_vmx_check_vmentry_hw(). Use BL as it is a callee-save register in both 32-bit and 64-bit ABIs, i.e. it can't be modified by vmx_update_host_rsp(), to avoid having to temporarily save/restore the launched flag.

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 Restructured Text 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.
