fb6f1aaeb4 interconnect: qcom: icc-rpmh: convert link_nodes to dynamic array
Declaring link_nodes as a double-pointer results in a syntax sugar in
the interconnect driver to typecast the array. Change the type of
link_nodes field to the array to remove the need for the extra typecast.

1868c027b6 tools/nolibc: make the "headers" target install all supported archs
The efforts we go through by installing a single arch are counter
productive when the base directory already supports them all, and
the arch-specific files are really small. Let's make the "headers"
target simply install headers for all supported archs and stop
trying to build a hybrid "arch.h" file on the fly, to instead keep
the generic one. Now the same nolibc headers installation will be
usable with any arch-specific uapi installation.

44bf8bbe29 tools/nolibc: add the more portable inttypes.h
It's often recommended to only use inttypes.h instead of stdint.h for
portability reasons since the former is always present when the latter
is present, but not conversely, and the former includes the latter. Due
to this some simple programs fail to build when including inttypes.h.
Let's add one that simply includes nolibc.h to better support these
programs.

c6f2dddfa7 clk: microchip: mpfs: use regmap for clocks
Convert the PolarFire SoC clock driver to use regmaps instead of iomem
addresses as a preparatory work for supporting the new binding for this
device that will only provide the second of the two register regions, and
will require the use of syscon regmap to access the "cfg" and "periph"
clocks currently supported by the driver.

This is effectively a revert of commit 4da2404bb0 ("clk: microchip:
mpfs: convert cfg_clk to clk_divider") and commit d815569783 ("clk:
microchip: mpfs: convert periph_clk to clk_gate") as it resurrects the
ops structures removed in those commits, with the readl()s and
writel()s replaced by regmap_read()s and regmap_writes()s.

eb43534ee4 dt-bindings: clk: microchip: mpfs: remove first reg region
The first reg region in this binding is not exclusively for clocks, as
evidenced by the dual role of this device as a reset controller at
present. The first region is however better described by a simple-mfd
syscon, but this would have require a significant re-write of the
devicetree for the platform, so the easy way out was chosen when reset
support was first introduced. The region doesn't just contain clock and
reset registers, it also contains pinctrl and interrupt controller
functionality, so drop the region from the clock binding so that it can
be described instead by a simple-mfd syscon rather than propagate this
incorrect description of the hardware to the new pic64gx SoC.

51d0656959 genirq/manage: Reduce priority of forced secondary interrupt handler
Crystal reports that the PCIe Advanced Error Reporting driver gets stuck
in an infinite loop on PREEMPT_RT:

Both the primary interrupt handler aer_irq() as well as the secondary
handler aer_isr() are forced into threads with identical priority.
Crystal writes that on the ARM system in question, the primary handler
has to clear an error in the Root Error Status register...

   "before the next error happens, or else the hardware will set the
    Multiple ERR_COR Received bit.  If that bit is set, then aer_isr()
    can't rely on the Error Source Identification register, so it scans
    through all devices looking for errors -- and for some reason, on
    this system, accessing the AER registers (or any Config Space above
    0x400, even though there are capabilities located there) generates
    an Unsupported Request Error (but returns valid data).  Since this
    happens more than once, without aer_irq() preempting, it causes
    another multi error and we get stuck in a loop."

The issue does not show on non-PREEMPT_RT because the primary handler
runs in hardirq context and thus can preempt the threaded secondary
handler, clear the Root Error Status register and prevent the secondary
handler from getting stuck.

Emulate the same behavior on PREEMPT_RT by assigning a lower default
priority to the secondary handler if the primary handler is forced into
a thread.

5eb579dfd4 timers/migration: Fix imbalanced NUMA trees
When a CPU from a new node boots, the old root may happen to be
connected to the new root even if their node mismatch, as depicted in
the following scenario:

1) CPU 0 boots and creates the first group for node 0.

   [GRP0:0]
    node 0
      |
    CPU 0

2) CPU 1 from node 1 boots and creates a new top that corresponds to
   node 1, but it also connects the old root from node 0 to the new root
   from node 1 by mistake.

             [GRP1:0]
              node 1
            /        \
           /          \
   [GRP0:0]             [GRP0:1]
    node 0               node 1
      |                    |
    CPU 0                CPU 1

3) This eventually leads to an imbalanced tree where some node 0 CPUs
   migrate node 1 timers (and vice versa) way before reaching the
   crossnode groups, resulting in more frequent remote memory accesses
   than expected.

                      [GRP2:0]
                      NUMA_NO_NODE
                     /             \
             [GRP1:0]              [GRP1:1]
              node 1               node 0
            /        \                |
           /          \             [...]
   [GRP0:0]             [GRP0:1]
    node 0               node 1
      |                    |
    CPU 0...              CPU 1...

A balanced tree should only contain groups having children that belong
to the same node:

                      [GRP2:0]
                      NUMA_NO_NODE
                     /             \
             [GRP1:0]              [GRP1:0]
              node 0               node 1
            /        \             /      \
           /          \           /        \
   [GRP0:0]          [...]      [...]    [GRP0:1]
    node 0                                node 1
      |                                     |
    CPU 0...                              CPU 1...

In order to fix this, the hierarchy must be unfolded up to the crossnode
level as soon as a node mismatch is detected. For example the stage 2
above should lead to this layout:

                      [GRP2:0]
                      NUMA_NO_NODE
                     /             \
             [GRP1:0]              [GRP1:1]
              node 0               node 1
              /                         \
             /                           \
        [GRP0:0]                        [GRP0:1]
        node 0                           node 1
          |                                |
       CPU 0                             CPU 1

This means that not only GRP1:0 must be created but also GRP1:1 and
GRP2:0 in order to prepare a balanced tree for next CPUs to boot.

fa9620355d timers/migration: Remove locking on group connection
Initializing the tmc's group, the group's number of children and the
group's parent can all be done without locking because:

  1) Reading the group's parent and its group mask is done locklessly.

  2) The connections prepared for a given CPU hierarchy are visible to the
     target CPU once online, thanks to the CPU hotplug enforced memory
     ordering.

  3) In case of a newly created upper level, the new root and its
     connections and initialization are made visible by the CPU which made
     the connections. When that CPUs goes idle in the future, the new link
     is published by tmigr_inactive_up() through the atomic RmW on
     ->migr_state.

  4) If CPUs were still walking up the active hierarchy, they could observe
     the new root earlier. In this case the ordering is enforced by an
     early initialization of the group mask and by barriers that maintain
     address dependency as explained in:

     b729cc1ec2 ("timers/migration: Fix another race between hotplug and idle entry/exit")
     de3ced72a7 ("timers/migration: Enforce group initialization visibility to tree walkers")

  5) Timers are propagated by a chain of group locking from the bottom to
     the top. And while doing so, the tree also propagates groups links
     and initialization. Therefore remote expiration, which also relies
     on group locking, will observe those links and initialization while
     holding the root lock before walking the tree remotely and update
     remote timers. This is especially important for migrators in the
     active hierarchy that may observe the new root early.

Therefore the locking is unnecessary at initialization. If anything, it
just brings confusion. Remove it.

4138787408 tick/sched: Limit non-timekeeper CPUs calling jiffies update
On large NUMA systems, while running a test program that saturates the
inter-processor and inter-NUMA links, acquiring the jiffies_lock can be
very expensive.

If the cpu designated to do jiffies updates (tick_do_timer_cpu) gets
delayed and other cpus decide to do the jiffies update themselves, a large
number of them decide to do so at the same time.

The inexpensive check against tick_next_period is far quicker than actually
acquiring the lock, so most of these get in line to obtain the lock.  If
obtaining the lock is slow enough, this spirals into the vast majority of
CPUs continuously being stuck waiting for this lock, just to obtain it and
find out that time has already been updated by another cpu. For example, on
one random entry to kdb by manually-injected NMI, 2912 of 3840 CPUs were
observed to be stuck there.

To avoid this, allow only one non-timekeeper CPU to call
tick_do_update_jiffies64() at any given time, resetting ts->stalled jiffies
only if the jiffies update function is actually called.

With this change, manually interrupting the test at most two CPUs are
observed to invoke tick_do_update_jiffies64() - the timekeeper and one
other.
