[ Upstream commit9258227e9d] When CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is not set, we look up dtl_idx in the lppaca to determine the number of entries in the buffer. Since lppaca is in big endian, we need to do an endian conversion before using this in our calculation to determine the number of entries in the buffer. Without this, we do not iterate over the existing entries in the DTL buffer properly. Fixes:7c105b63bd("powerpc: Add CONFIG_CPU_LITTLE_ENDIAN kernel config option.") Signed-off-by: Naveen N.

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.
