Pull s390 fixes from Vasily Gorbik:

 - a few ptrace fixes mostly for strace and seccomp_bpf kernel tests
   findings

 - cleanup unused pm callbacks in virtio ccw

 - replace kmalloc + memset with kzalloc in crypto

 - use $(LD) for vDSO linkage to make clang happy

 - fix vDSO clock_getres() to preserve the same behaviour as
   posix_get_hrtimer_res()

 - fix workqueue cpumask warning when NUMA=n and nr_node_ids=2

 - reduce SLSB writes during input processing, improve warnings and
   cleanup qdio_data usage in qdio

 - a few fixes to use scnprintf() instead of snprintf()

   checking required ftrace interfaces in each test case.

selftests/ftrace: Support ":README" suffix for requires

2020-06-16T16:42:47+00:00

Add ":README" suffix support for the requires list, so that
the testcase can list up the required string for README file
to the requires list.

Note that the required string is treated as a fixed string,
instead of regular expression. Also, the testcase can specify
a string containing spaces with quotes. E.g.

# requires: "place: [:]":README

selftests/ftrace: Support ":tracer" suffix for requires

2020-06-16T16:42:10+00:00

Add ":tracer" suffix support for the requires list, so that
the testcase can list up the required tracer (e.g. function)
to the requires list.

For example, if the testcase requires function_graph tracer,
it can write requires list as below instead of checking
available_tracers.

# requires: function_graph:tracer

selftests/ftrace: Convert check_filter_file() with requires list

2020-06-16T16:41:32+00:00

Since check_filter_file() is basically checking the filter
tracefs file, we can convert it into requires list.

selftests/ftrace: Convert required interface checks into requires list

2020-06-16T16:39:20+00:00

Convert the required tracefs interface checking code with
requires: list.

selftests/ftrace: Add "requires:" list support

2020-06-16T15:19:08+00:00

Introduce "requires:" list to check required ftrace interface
for each test. This will simplify the interface checking code
and unify the error message. Another good point is, it can
skip the ftrace initializing.

Note that this requires list must be written as a shell
comment.

selftests/ftrace: Return unsupported for the unconfigured features

2020-06-16T15:16:27+00:00

As same as other test cases, return unsupported if kprobe_events
or argument access feature are not found.

There can be a new arch which does not port those features yet,
and an older kernel which doesn't support it.
Those can not enable the features.

selftests/ftrace: Allow ":" in description

2020-06-16T15:15:40+00:00

Allow ":" in the description line. Currently if there is ":"
in the test description line, the description is cut at that
point, but that was unintended.

selftests/seccomp: s390 shares the syscall and return value register

2020-06-16T11:44:04+00:00

s390 cannot set syscall number and reture code at the same time,
so set the appropriate flag to indicate it.
