Linux kernel source tree
9b81c0211c
When the masked interrupt handler clears MSR[EE] for an interrupt in the PACA_IRQ_MUST_HARD_MASK set, it does not set PACA_IRQ_HARD_DIS. This makes them get out of synch. With that taken into account, it's only low level irq manipulation (and interrupt entry before reconcile) where they can be out of synch. This makes the code less surprising. It also allows the IRQ replay code to rely on the IRQ_HARD_DIS value and not have to mtmsrd again in this case (e.g., for an external interrupt that has been masked). The bigger benefit might just be that there is not such an element of surprise in these two bits of state.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
