Pull powerpc fixes from Michael Ellerman:
"Some things that I missed due to travel, or that came in late.
Two fixes also going to stable:
- A revert of a buggy change to the 8xx TLB miss handlers.
- Our flushing of SPE (Signal Processing Engine) registers on fork
was broken.
Other changes:
- A change to the KVM decrementer emulation to use proper APIs.
- Some cleanups to the way we do code patching in the 8xx code.
- Expose the maximum possible memory for the system in
/proc/powerpc/lparcfg.
- Merge some updates from Scott: "a couple device tree updates, and a
fix for a missing prototype warning"
A few other minor fixes and a handful of fixes for our selftests.
Thanks to: Aravinda Prasad, Breno Leitao, Camelia Groza, Christophe
Leroy, Felipe Rechia, Joel Stanley, Naveen N. Rao, Paul Mackerras,
Scott Wood, Tyrel Datwyler"

We are using 'dscr_insn' as a label in inline asm to identify if a
SIGILL was generated by the mtspr instruction at that point. However,
with inline assembly, the compiler is still free to duplicate the asm
statement for optimization purposes, which results in the label being
defined twice with the error:
/tmp/ccerQCql.s:874: Error: symbol `dscr_insn' is already defined
With different compiler versions, we may also see:
/tmp/ccJzLDlN.o:(.toc+0x0): undefined reference to `dscr_insn'
Remove the use of the label in the inline assembly. Instead, just look
for the offending instruction in the signal handler.

Use TEST_GEN_PROGS and don't redefine all, this makes the out-of-tree
build work. We need to move the extra dependencies below the include
of lib.mk, because it adds the $(OUTPUT) prefix if it's defined.
We can also drop the clean rule, lib.mk does it for us.

We should use TEST_GEN_PROGS, not TEST_PROGS. That tells the selftests

When running the rfi_flush test, if the system is loaded, we see two
issues:
1. The L1d misses when rfi_flush is disabled increase significantly due
to other workloads interfering with the cache.
2. The L1d misses when rfi_flush is enabled sometimes goes slightly
below the expected number of misses.
To address these, let's relax the expected number of L1d misses:
1. When rfi_flush is disabled, we allow upto half the expected number of
the misses for when rfi_flush is enabled.
2. When rfi_flush is enabled, we allow ~1% lower number of cache misses.

Test ptrace-tm-spd-gpr fails on current kernel (4.19) due to a segmentation
fault that happens on the child process prior to setting cptr[2] = 1. This
causes the parent process to wait forever at 'while (!pptr[2])' and the test to
be killed by the test harness framework by timeout, thus, failing.
The segmentation fault happens because of a inline assembly being
generated as:
0x10000355c <tm_spd_gpr+492> lfs f0, 0(0)
This is reading memory position 0x0 and causing the segmentation fault.
This code is being generated by ASM_LOAD_FPR_SINGLE_PRECISION(flt_4), where
flt_4 is passed to the inline assembly block as:
[flt_4] "r" (&d)
Since the inline assembly 'r' constraint means any GPR, gpr0 is being
chosen, thus causing this issue when issuing a Load Floating-Point Single
instruction.
This patch simply changes the constraint to 'b', which specify that this
register will be used as base, and r0 is not allowed to be used, avoiding
this issue.
Other than that, removing flt_2 register from the input operands, since it
is not used by the inline assembly code at all.

In a previous patch, mlxsw was updated to configure a minimum bandwidth

Since the minimum shaper is now being enabled for MC TCs, it's
unreasonable to expect no UC traffic loss. Minimal min shaper value is
200Mbps, which is 20% of the 1Gbps that this test configures on egress.
To cover for glitches, tolerate up to 25% UC degradation under MC
overload.

Fix the synthetic event test case to remove event correctly.
If redirecting command to synthetic_event file without append
mode, it cleans up all existing events and execute (parse) the
command. This means "delete event" always fails to find the
target event.
Since previous synthetic event has a bug which doesn't return
-ENOENT even if it fails to find the deleting event, this test
passed. But fixing that bug, this test fails because this test
itself has a bug.
This fixes that bug by trying to delete event right after
adding an event, and use append mode redirection ('>>') instead
of normal redirection ('>').

Commit b39b5f411dcf ("bpf: add cg_skb_is_valid_access for
BPF_PROG_TYPE_CGROUP_SKB") added support for returning pkt pointers
for direct packet access. Given this program type is allowed for both
unprivileged and privileged users, we shouldn't allow unprivileged
ones to use it, e.g. besides others one reason would be to avoid any
potential speculation on the packet test itself, thus guard this for
root only.

Given BPF_PROG_TYPE_CGROUP_SKB program types are also valid in an
unprivileged setting, lets not omit these tests and potentially
have issues fall through the cracks. Make this more obvious by
adding a small test_as_unpriv() helper.

A driver to let userspace turn memfd regions into dma-bufs.
Use case: Allows qemu create dmabufs for the vga framebuffer or
virtio-gpu ressources. Then they can be passed around to display
those guest things on the host. To spice client for classic full
framebuffer display, and hopefully some day to wayland server for
seamless guest window display.

If test is being directly executed (with stdout opened on the
terminal) and the terminal capabilities indicate enough
colors, then use the existing scheme of green, red, and blue
to show when tests pass, fail or end in a different way.
When running the tests redirecting the stdout, for instance,
to a file, then colors are not shown, thus producing a more
readable output.

Now that ftracetest has over 80 tests, it is difficult to simply scroll
up the console window to find the failed tests when it reports just two
tests have failed. In order to make this stand out better, have the
color of the word "PASS" be green, "FAIL" and "XFAIL" be red, and all
other results be blue. This helps tremendously in quickly spotting the
failed tests by just scrolling up the console window.

When simply running `make' from the selftests top dir, this
error shows up:
cc -O2 -g -std=gnu99 -Wall -I../../../../usr/include/ -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/uuid gpio-mockup-chardev.c ../../../gpio/gpio-utils.o -lmount -o gpio-mockup-chardev
cc: error: ../../../gpio/gpio-utils.o: No such file or directory
<builtin>: recipe for target 'gpio-mockup-chardev' failed
make[1]: *** [gpio-mockup-chardev] Error 1
because the output directory is set to "selftests/gpio" and
all binaries built from ../../../gpio/ end up there. In fact,
they appear as, exempli gratia:
* gpiogpio-event-mon
* gpiogpio-hammer
* gpioinclude/
* gpiolsgpio
which is wrong, as it's missing a directory separator
somewhere.
This patch sets straight the output directory when building
../../../gpio/ so that binaries don't cross paths.

This patch cleans up the Makefile by restructuring a couple of
things, namely:
1) change explicit paths in targets for variables
2) substitute a variable (BINARIES) for another, part of the
selftests build system (TEST_PROGS_EXTENDED)
3) proper cleaning up of the EXTRA objects
The resulting Makefile is much more readable and manageable.

When ioctls for WDIOC_SETOPTIONS (WDIOS_DISABLECARD or WDIOS_ENABLECARD),
WDIOC_SETTIMEOUT, and WDIOC_SETPRETIMEOUT fail, the error path continues
to handler watchdog timer until user terminates it. When ioctl returns
error, it might not be safe to let the watchdog tick. The error could be
due an unsupported ioctl command or some other error.
Fix it to handle error paths as oneshot to stop the watchdog ticks and
exit right away.
