In the IRQ injection tracepoint, differentiate between Hard IRQs and Soft "IRQs", i.e. interrupts that are reinjected after incomplete delivery of a software interrupt from an INTn instruction. Tag reinjected interrupts as such, even though the information is usually redundant since soft interrupts are only ever reinjected by KVM. Though rare in practice, a hard IRQ can be reinjected.

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.
