[ Upstream commit 82ce6eb1dd ]
A test for the basic NAT functionality uses ip command which needs veth
device. There is a condition where the kernel support for veth is not
compiled into the kernel and the test script breaks. This patch contains
code for reasonable error display and correct code exit.

When an icmp error such as pkttoobig is received, conntrack checks
if the "inner" header (header of packet that did not fit link mtu)
is matches an existing connection, and, if so, sets that packet as
being related to the conntrack entry it found.
It was recently reported that this "related" setting also works
if the inner header is from another, different connection (i.e.,
artificial/forged icmp error).
Add a test, followup patch will add additional "inner dst matches
outer dst in reverse direction" check before setting related state.

commit 808153e118 upstream.
devm_memremap_pages() is a facility that can create struct page entries
for any arbitrary range and give drivers the ability to subvert core
aspects of page management.
Specifically the facility is tightly integrated with the kernel's memory
hotplug functionality. It injects an altmap argument deep into the
architecture specific vmemmap implementation to allow allocating from
specific reserved pages, and it has Linux specific assumptions about page
structure reference counting relative to get_user_pages() and
get_user_pages_fast(). It was an oversight and a mistake that this was
not marked EXPORT_SYMBOL_GPL from the outset.
Again, devm_memremap_pagex() exposes and relies upon core kernel internal
assumptions and will continue to evolve along with 'struct page', memory
hotplug, and support for new memory types / topologies. Only an in-kernel
GPL-only driver is expected to keep up with this ongoing evolution. This
interface, and functionality derived from this interface, is not suitable
for kernel-external drivers.

[ Upstream commit 7c27a26e1e ]
There are some powerpc selftests, as tm/tm-unavailable, that run for a long
period (>120 seconds), and if it is interrupted, as pressing CRTL-C
(SIGINT), the foreground process (harness) dies but the child process and
threads continue to execute (with PPID = 1 now) in background.
In this case, you'd think the whole test exited, but there are remaining
threads and processes being executed in background. Sometimes these
zombies processes are doing annoying things, as consuming the whole CPU or
dumping things to STDOUT.
This patch fixes this problem by attaching an empty signal handler to
SIGINT in the harness process. This handler will interrupt (EINTR) the
parent process waitpid() call, letting the code to follow through the
normal flow, which will kill all the processes in the child process group.
This patch also fixes a typo.

A few changes improve the overall usability of the test:
* fix a hard-coded maximum frequency (3300),
* don't adjust the CPU frequency if only evaluating results,
* fix a comparison for multiple frequencies.
A symptom of that last issue looked like this:
./run.sh: line 107: [: too many arguments
./run.sh: line 110: 3099
3099
3100-3100: syntax error in expression (error token is \"3099
3100-3100\")
Because a check will count how many differente frequencies
there are among the CPUs of the system, and after they are
tallied another read is performed, which might produce
different results.

The subpage_prot syscall is only functional when the system is using
the Hash MMU. Since commit 5b2b807147 ("powerpc/mm: Invalidate
subpage_prot() system call on radix platforms") it returns ENOENT when
the Radix MMU is active. Currently this just makes the test fail.
Additionally the syscall is not available if the kernel is built with
4K pages, or if CONFIG_PPC_SUBPAGE_PROT=n, in which case it returns
ENOSYS because the syscall is missing entirely.
So check explicitly for ENOENT and ENOSYS and skip if we see either of
those.

The tm-resched-dscr test has started failing sometimes, depending on
what compiler it's built with, eg:
test: tm_resched_dscr
Check DSCR TM context switch: tm-resched-dscr: tm-resched-dscr.c:76: test_body: Assertion `rv' failed.
!! child died by signal 6
When it fails we see that the compiler doesn't initialise rv to 1 before
entering the inline asm block. Although that's counter intuitive, it
is allowed because we tell the compiler that the inline asm will write
to rv (using "=r"), meaning the original value is irrelevant.
Marking it as a read/write parameter would presumably work, but it seems
simpler to fix it by setting the initial value of rv in the inline asm.
