Tiezhu Yang 9becf957e0 MIPS/bpf: Enable bpf_probe_read{, str}() on MIPS again 
[ Upstream commit 66633abd06 ]

After commit 0ebeea8ca8 ("bpf: Restrict bpf_probe_read{, str}() only to
archs where they work"), bpf_probe_read{, str}() functions were no longer
available on MIPS, so there exist some errors when running bpf program:

root@linux:/home/loongson/bcc# python examples/tracing/task_switch.py
bpf: Failed to load program: Invalid argument
[...]
11: (85) call bpf_probe_read#4
unknown func bpf_probe_read#4
[...]
Exception: Failed to load BPF program count_sched: Invalid argument

ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE should be restricted to archs
with non-overlapping address ranges, but they can overlap in EVA mode
on MIPS, so select ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE if !EVA in
arch/mips/Kconfig, otherwise the bpf old helper bpf_probe_read() will
not be available.

This is similar with the commit d195b1d1d1 ("powerpc/bpf: Enable
bpf_probe_read{, str}() on powerpc again").

Fixes: 0ebeea8ca8 ("bpf: Restrict bpf_probe_read{, str}() only to archs where they work")

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.
