Some systems have multiple watchdog devices where the first device
registered is assigned to the /dev/watchdog device file. In order
to test other watchdog devices, add an optional file argument for
selecting non-default watchdog devices for testing.

The seccomp selftest goes to some length to build against older kernel
headers, viz. all the #ifdefs at the beginning of the file.
Commit 201766a20e30 ("ptrace: add PTRACE_GET_SYSCALL_INFO request")
introduces some additional macros, but doesn't do the #ifdef dance.
Let's add that dance here to avoid:
gcc -Wl,-no-as-needed -Wall seccomp_bpf.c -lpthread -o seccomp_bpf
In file included from seccomp_bpf.c:51:

Now that the default perf_events paranoid level is set to 2, a regular
user cannot monitor kernel level activity anymore. As such, with the
following cmdline:
$ perf record -e cycles date
The perf tool first tries cycles:uk but then falls back to cycles:u as
can be seen in the perf report --header-only output:
cmdline : /export/hda3/tmp/perf.tip record -e cycles ls
event : name = cycles:u, , id = { 436186, ... }
This is okay as long as there is way to learn the priv level was changed
internally by the tool.
But consider a similar example:
$ perf record -b -e cycles date
Error:
You may not have permission to collect stats.
Consider tweaking /proc/sys/kernel/perf_event_paranoid,
which controls use of the performance events system by
unprivileged users (without CAP_SYS_ADMIN).
...
Why is that treated differently given that the branch sampling inherits the
priv level of the first event in this case, i.e., cycles:u? It turns out
that the branch sampling code is more picky and also checks exclude_hv.
In the fallback path, perf record is setting exclude_kernel = 1, but it
does not change exclude_hv. This does not seem to match the restriction
imposed by paranoid = 2.
This patch fixes the problem by forcing exclude_hv = 1 in the fallback
for paranoid=2. With this in place:
$ perf record -b -e cycles date
cmdline : /export/hda3/tmp/perf.tip record -b -e cycles ls
event : name = cycles:u, , id = { 436847, ... }
And the command succeeds as expected.
V2 fix a white space.
Committer testing:
After aplying the patch we get:
[acme@quaco ~]$ perf record -b -e cycles date
WARNING: Kernel address maps (/proc/{kallsyms,modules}) are restricted,
check /proc/sys/kernel/kptr_restrict and /proc/sys/kernel/perf_event_paranoid.

That warning about restricted kernel maps will be suppressed in a follow
up patch, as perf_event_attr.exclude_kernel is set, i.e. no samples for
the kernel will be taken and thus no need for those maps.

(at least clang-9, did not check gcc) notice that there is one enum value
that is not handled here:
block/t10-pi.c:62:11: error: enumeration value 'T10_PI_TYPE0_PROTECTION'

Add a BUG_ON statement if we ever get to t10_pi_verify function with

valid types.

The platform_get_resource() function doesn't return error pointers, it
returns NULL. The way this is normally done, is that we pass the NULL
resource to devm_ioremap_resource() and then check for errors from that.

Commit feb4eb060c3a ("firmware: bcm47xx_nvram: Correct size_t printf
format") was wrong, and changed a printout of 'header.len' - which is an
u32 type - to use '%zu'.
It apparently did pattern matching on the other case, where it printed
out 'nvram_len', which is indeed of type 'size_t'.
Rather than undoing the change, this just makes it use the variable that
the change seemed to expect to be used.

It's an unusual configuration, and was apparently never tested, and not
caught in linux-next because of a combination of travels and it making
it into the tree too late.
The fix is to simply move the #define to outside the CONFIG_MODULE
section, since MODULE_INFO() will do the right thing.

git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules updates from Jessica Yu:
"The main bulk of this pull request introduces a new exported symbol
namespaces feature. The number of exported symbols is increasingly
growing with each release (we're at about 31k exports as of 5.3-rc7)
and we currently have no way of visualizing how these symbols are
"clustered" or making sense of this huge export surface.
Namespacing exported symbols allows kernel developers to more
explicitly partition and categorize exported symbols, as well as more
easily limiting the availability of namespaced symbols to other parts
of the kernel. For starters, we have introduced the USB_STORAGE
namespace to demonstrate the API's usage. I have briefly summarized
the feature and its main motivations in the tag below.
Summary:
- Introduce exported symbol namespaces.
This new feature allows subsystem maintainers to partition and
categorize their exported symbols into explicit namespaces. Module
authors are now required to import the namespaces they need.
Some of the main motivations of this feature include: allowing
kernel developers to better manage the export surface, allow
subsystem maintainers to explicitly state that usage of some
exported symbols should only be limited to certain users (think:
inter-module or inter-driver symbols, debugging symbols, etc), as
well as more easily limiting the availability of namespaced symbols
to other parts of the kernel.
With the module import requirement, it is also easier to spot the
misuse of exported symbols during patch review.
Two new macros are introduced: EXPORT_SYMBOL_NS() and
EXPORT_SYMBOL_NS_GPL(). The API is thoroughly documented in
Documentation/kbuild/namespaces.rst.
- Some small code and kbuild cleanups here and there"

Pull MIPS updates from Paul Burton:
"Main MIPS changes:
- boot_mem_map is removed, providing a nice cleanup made possible by
the recent removal of bootmem.
- Some fixes to atomics, in general providing compiler barriers for
smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs
or MIPS32 systems using cmpxchg64().
- Conversion to the new generic VDSO infrastructure courtesy of
Vincenzo Frascino.
- Removal of undefined behavior in set_io_port_base(), fixing the
behavior of some MIPS kernel configurations when built with recent
clang versions.
- Initial MIPS32 huge page support, functional on at least Ingenic
SoCs.
- pte_special() is now supported for some configurations, allowing
among other things generic fast GUP to be used.
- Miscellaneous fixes & cleanups.
And platform specific changes:
- Major improvements to Ingenic SoC support from Paul Cercueil,
mostly enabled by the inclusion of the new TCU (timer-counter unit)
drivers he's spent a very patient year or so working on. Plus some
fixes for X1000 SoCs from Zhou Yanjie.
- Netgear R6200 v1 systems are now supported by the bcm47xx platform.

Putting a struct stmmac_rss object on the stack is a bad idea,
as it exceeds the warning limit for a stack frame on 32-bit architectures:

As the object is the trivial empty case, change the called function
to accept a NULL pointer to mean the same thing and remove the
large variable in the two callers.

The TCA_KIND attribute is of NLA_STRING which does not check
