Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=84061fff2ad98a7809f00e88a54f584f84830388

--------------------------------

commit bb066506 upstream.

Convert __vmx_vcpu_run()'s 'launched' argument to 'flags', in
preparation for doing SPEC_CTRL handling immediately after vmexit, which
will need another flag.

This is much easier than adding a fourth argument, because this code
supports both 32-bit and 64-bit, and the fourth argument on 32-bit would
have to be pushed on the stack.

Note that __vmx_vcpu_run_flags() is called outside of the noinstr
critical section because it will soon start calling potentially
traceable functions.
