commitab9dbf771fupstream. This reverts commita3b2cb30f2. That commit tried to fix problems with panic on powerpc in certain circumstances, where some output from the generic panic code was being dropped. Unfortunately, it breaks things worse in other circumstances. In particular when running a PAPR guest, it will now attempt to reboot instead of informing the hypervisor (KVM or PowerVM) that the guest has crashed. The crash notification is important to some virtualization management layers. Revert it for now until we can come up with a better solution.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
