Extend the kvm_exit tracepoint to align it with kvm_nested_vmexit in terms of what information is captured. On SVM, add interrupt info and error code, while on VMX it add IDT vectoring and error code. This sets the stage for macrofying the kvm_exit tracepoint definition so that it can be reused for kvm_nested_vmexit without loss of information. Opportunistically stuff a zero for VM_EXIT_INTR_INFO if the VM-Enter failed, as the field is guaranteed to be invalid. Note, it'd be possible to further filter the interrupt/exception fields based on the VM-Exit reason, but the helper is intended only for tracepoints, i.e. an extra VMREAD or two is a non-issue, the failed VM-Enter case is just low hanging fruit.

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.
