b923f1247b A set oftimekeeping/VDSO updates:
- Preparatory work to allow S390 to switch over to the generic VDSO
    implementation.
 
    S390 requires that the VDSO data pointer is handed in to the counter
    read function when time namespace support is enabled. Adding the pointer
    is a NOOP for all other architectures because the compiler is supposed
    to optimize that out when it is unused in the architecture specific
    inline. The change also solved a similar problem for MIPS which
    fortunately has time namespaces not yet enabled.
 
    S390 needs to update clock related VDSO data independent of the
    timekeeping updates. This was solved so far with yet another sequence
    counter in the S390 implementation. A better solution is to utilize the
    already existing VDSO sequence count for this. The core code now exposes
    helper functions which allow to serialize against the timekeeper code
    and against concurrent readers.
 
    S390 needs extra data for their clock readout function. The initial
    common VDSO data structure did not provide a way to add that. It now has
    an embedded architecture specific struct embedded which defaults to an
    empty struct.
 
    Doing this now avoids tree dependencies and conflicts post rc1 and
    allows all other architectures which work on generic VDSO support to
    work from a common upstream base.
 
  - A trivial comment fix.

b6b178e38f A set of posix CPU timer changes which allows to defer the heavy work of
posix CPU timers into task work context. The tick interrupt is reduced to a
 quick check which queues the work which is doing the heavy lifting before
 returning to user space or going back to guest mode. Moving this out is
 deferring the signal delivery slightly but posix CPU timers are inaccurate
 by nature as they depend on the tick so there is no real damage. The
 relevant test cases all passed.
 
 This lifts the last offender for RT out of the hard interrupt context tick
 handler, but it also has the general benefit that the actual heavy work is
 accounted to the task/process and not to the tick interrupt itself.
 
 Further optimizations are possible to break long sighand lock hold and
 interrupt disabled (on !RT kernels) times when a massive amount of posix
 CPU timers (which are unpriviledged) is armed for a task/process.
 
 This is currently only enabled for x86 because the architecture has to
 ensure that task work is handled in KVM before entering a guest, which was
 just established for x86 with the new common entry/exit code which got
 merged post 5.8 and is not the case for other KVM architectures.

e1d74fbe50 OpenRISC updates for 5.9
A few patches all over the place during this cycle, mostly bug and
 sparse warning fixes for OpenRISC, but a few enhancements too.  Note,
 there are 2 non OpenRISC specific fixups.
 
 Non OpenRISC fixes:
 
  - In init we need to align the init_task correctly to fix an issue with
    MUTEX_FLAGS, reviewed by Peter Z.  No one picked this up so I kept it
    on my tree.
  - In asm-generic/io.h I fixed up some sparse warnings, OK'd by Arnd.
    Arnd asked to merge it via my tree.
 
 OpenRISC fixes:
 
  - Many fixes for OpenRISC sprase warnings.
  - Add support OpenRISC SMP tlb flushing rather than always flushing the
    entire TLB on every CPU.
  - Fix bug when dumping stack via /proc/xxx/stack of user threads.

This can happen if ptrace() or sigreturn() pokes an LDT selector into FS
or GS for a task with no LDT and something tries to read the base before
a return to usermode notices the bad selector and fixes it.

The fix is to make sure ldt pointer is not NULL.

0fd9cc6b0c Modules updates for v5.9
Summary of modules changes for the 5.9 merge window:
 
 - Have modules that use symbols from proprietary modules inherit the
   TAINT_PROPRIETARY_MODULE taint, in an effort to prevent GPL shim modules that
   are used to circumvent _GPL exports. These are modules that claim to be GPL
   licensed while also using symbols from proprietary modules. Such modules will
   be rejected while non-GPL modules will inherit the proprietary taint.
 
 - Module export space cleanup. Unexport symbols that are unused outside of
   module.c or otherwise used in only built-in code.

5f0b06da5c dt-bindings: Remove more cases of 'allOf' containing a '$ref'
Another wack-a-mole pass of killing off unnecessary 'allOf + $ref'
usage.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

f516fb704d dt-bindings: Whitespace clean-ups in schema files
Clean-up incorrect indentation, extra spaces, long lines, and missing
EOF newline in schema files. Most of the clean-ups are for list
indentation which should always be 2 spaces more than the preceding
keyword.

Found with yamllint (which I plan to integrate into the checks).

c7a14fdcb3 perf build-ids: Fall back to debuginfod query if debuginfo not found
During a perf-record, use the -ldebuginfod API to query a debuginfod
server, should the debug data not be found in the usual system
locations.  If successful, the usual $HOME/.debug dir is populated.

Tested with:

  $ find .

  $ rm -rf ~/.debug/ ; mkdir ~/.debug

  $ perf record make tags

Note the 'debug' file is created in the last run.

Note that currently the debuginfo data are downloaded only on record path,
we still need add this support to perf build-id/report.. and test ;-)

b1d84af6f5 perf ftrace: Add support for tracing option 'func_stack_trace'
This adds support to display call trace for function tracer. To do this,
just specify a '--func-opts call-graph' option.

Example:

  $ sudo perf ftrace -T vfs_read --func-opts call-graph
   iio-sensor-prox-855   [003]   6168.369657: vfs_read <-ksys_read
   iio-sensor-prox-855   [003]   6168.369677: <stack trace>
   => vfs_read
   => ksys_read
   => __x64_sys_read
   => do_syscall_64
   => entry_SYSCALL_64_after_hwframe
   ...

846e193980 perf ftrace: Add option '-m/--buffer-size' to set per-cpu buffer size
This adds an option '-m/--buffer-size' to allow us set the size of per-cpu
tracing buffer.

Committer testing:

Before running with this option:

  # find /sys/kernel/tracing/ -name buffer_size_kb | xargs cat
  1408
  1408
  1408
  1408
  1408
  1408
  1408
  1408
  1408
  #

Then, run:

  # perf ftrace -m 2048K | head -10
   2)               |  mutex_unlock() {
   2)   ==========> |
   2)               |    smp_irq_work_interrupt() {
   2)               |      irq_enter() {
   2)   0.121 us    |        rcu_irq_enter();
   2)   0.128 us    |        irqtime_account_irq();
   2)   0.719 us    |      }
   2)               |      __wake_up() {
   2)               |        __wake_up_common_lock() {
   2)   0.105 us    |          _raw_spin_lock_irqsave();
  #

Now look at those tracefs knobs:

  # find /sys/kernel/tracing/ -name buffer_size_kb | xargs cat
  2048
  2048
  2048
  2048
  2048
  2048
  2048
  2048
  2048
  #

This should be similar to the -m option in the other perf tools, such as
'perf record', 'perf trace', etc.

eb6d31ae22 perf ftrace: Select function/function_graph tracer automatically
The '-g/-G' options have already implied function_graph tracer should be
used instead of function tracer. So we don't need extra option
'--tracer' in this case.

This patch changes the behavior as below:

  - If '-g' or '-G' option is on, then function_graph tracer is used.
  - If '-T' or '-N' option is on, then function tracer is used.
  - The function_graph has priority over function tracer.
  - The option '--tracer' only take effect if neither -g/-G nor -T/-N
    is specified.

Here are some examples.

This will start tracing all functions using default tracer:

  $ sudo perf ftrace

This will trace all functions using function graph tracer:

  $ sudo perf ftrace -G '*'

This will trace function vfs_read using function graph tracer:

  $ sudo perf ftrace -G vfs_read

This will trace function vfs_read using function tracer:

  $ sudo perf ftrace -T vfs_read

Committer notes:

Using '-h -G' will tell what that option is about, so to further clarify
the above examples:

  # perf ftrace -h -G

    -G, --graph-funcs <func>	Set graph filter on given functions

  # perf ftrace -h -g

    -g, --nograph-funcs <func>	Set nograph filter on given functions

  # perf ftrace -h -T

    -T, --trace-funcs <func>	trace given functions only

  # perf ftrace -h -N

    -N, --notrace-funcs <func>	do not trace given functions

  #

cc172ff301 sched/debug: Fix the alignment of the show-state debug output
Current sysrq(t) output task fields name are not aligned with
actual task fields value, e.g.:

	kernel:  task                        PC stack   pid father
	kernel: systemd         S12456     1      0 0x00000000
	kernel: Call Trace:
	kernel: ? __schedule+0x240/0x740

To make it more readable, print fields name together with task fields
value in the same line, with fixed width:

	kernel: sysrq: Show State
	kernel: task:systemd         state:S stack:12920 pid:    1 ppid:     0 flags:0x00000000

fa8de0a3bf kconfig: qconf: do not limit the pop-up menu to the first row
If you right-click the first row in the option tree, the pop-up menu
shows up, but if you right-click the second row or below, the event
is ignored due to the following check:

  if (e->y() <= header()->geometry().bottom()) {

Perhaps, the intention was to show the pop-menu only when the tree
header was right-clicked, but this handler is not called in that case.

Since the origin of e->y() starts from the bottom of the header,
this check is odd.

Going forward, you can right-click anywhere in the tree to get the
pop-up menu.
