Naveen N. Rao 9fac39480e powerpc/xmon: Fix disabling tracing while in xmon [ Upstream commit `aaf06665f7` ] Commit `ed49f7fd64` ("powerpc/xmon: Disable tracing when entering xmon") added code to disable recording trace entries while in xmon. The commit introduced a variable 'tracing_enabled' to record if tracing was enabled on xmon entry, and used this to conditionally enable tracing during exit from xmon. However, we are not checking the value of 'fromipi' variable in xmon_core() when setting 'tracing_enabled'. Due to this, when secondary cpus enter xmon, they will see tracing as being disabled already and tracing won't be re-enabled on exit. Fix the same.

README

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.
