Alexey Kardashevskiy 2a9c4f40ab powerpc/powernv: Fix opal tracepoints with JUMP_LABEL=n The recent commit to allow calling OPAL calls in real mode, commit `ab9bad0ead` ("powerpc/powernv: Remove separate entry for OPAL real mode calls"), introduced a bug when CONFIG_JUMP_LABEL=n. The commit moved the "mfmsr r12" prior to the call to OPAL_BRANCH, but we missed that OPAL_BRANCH clobbers r12 when jump labels are disabled. This leads to us using the tracepoint refcount as the MSR value, typically zero, and saving that into PACASAVEDMSR. When we return from OPAL we use that value as the MSR value for rfid, meaning we switch to 32-bit BE real mode - hilarity ensues. Fix it by using r11 in OPAL_BRANCH, which is not live at the time the macro is used in OPAL_CALL.

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.
