Move HF_NMI_MASK and HF_IRET_MASK (a.k.a. "waiting for IRET") out of the common "hflags" and into dedicated flags in "struct vcpu_svm". The flags are used only for the SVM and thus should not be in hflags. Tracking NMI masking in software isn't SVM specific, e.g. VMX has a similar flag (soft_vnmi_blocked), but that's much more of a hack as VMX can't intercept IRET, is useful only for ancient CPUs, i.e. will hopefully be removed at some point, and again the exact behavior is vendor specific and shouldn't ever be referenced in common code. converting VMX No functional change is intended.

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.
