Elvira Khabirova 58c0d0b2d4 mips: fix syscall_get_nr
commit 85cc91e2ba4262a602ec65e2b76c4391a9e60d3d upstream.

The implementation of syscall_get_nr on mips used to ignore the task
argument and return the syscall number of the calling thread instead of
the target thread.

The bug was exposed to user space by commit 201766a20e ("ptrace: add
PTRACE_GET_SYSCALL_INFO request") and detected by strace test suite.

Fixes: c2d9f17757 ("MIPS: Fix syscall_get_nr for the syscall exit tracing.")

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.

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.
