c43e55796d m68k: mm: fix node memblock init
After pulling 5.7.0 (linux-next merge), mcf5441x mmu boot was
hanging silently.

memblock_add() seems not appropriate, since using MAX_NUMNODES
as node id, while memblock_add_node() sets up memory for node id 0.

d63bd8c81d m68k: nommu: register start of the memory with memblock
The m68k nommu setup code didn't register the beginning of the physical
memory with memblock because it was anyway occupied by the kernel. However,
commit fa3354e4ea ("mm: free_area_init: use maximal zone PFNs rather than
zone sizes") changed zones initialization to use memblock.memory to detect
the zone extents and this caused inconsistency between zone PFNs and the
actual PFNs:

77b48bea2f Drivers: hv: Change flag to write log level in panic msg to false
When the kernel panics, one page of kmsg data may be collected and sent to
Hyper-V to aid in diagnosing the failure.  The collected kmsg data typically
 contains 50 to 100 lines, each of which has a log level prefix that isn't
very useful from a diagnostic standpoint.  So tell kmsg_dump_get_buffer()
to not include the log level, enabling more information that *is* useful to
fit in the page.

Requesting in stable kernels, since many kernels running in production are
stable releases.

5f8f06425a thermal/drivers/rcar_gen3: Fix undefined temperature if negative
As description for DIV_ROUND_CLOSEST in file include/linux/kernel.h.
  "Result is undefined for negative divisors if the dividend variable
   type is unsigned and for negative dividends if the divisor variable
   type is unsigned."

In current code, the FIXPT_DIV uses DIV_ROUND_CLOSEST but has not
checked sign of divisor before using. It makes undefined temperature
value in case the value is negative.

This patch fixes to satisfy DIV_ROUND_CLOSEST description
and fix bug too. Note that the variable name "reg" is not good
because it should be the same type as rcar_gen3_thermal_read().
However, it's better to rename the "reg" in a further patch as
cleanup.

371a3bc79c thermal/drivers/cpufreq_cooling: Fix wrong frequency converted from power
The function cpu_power_to_freq is used to find a frequency and set the
cooling device to consume at most the power to be converted. For example,
if the power to be converted is 80mW, and the em table is as follow.
struct em_cap_state table[] = {
	/* KHz     mW */
	{ 1008000, 36, 0 },
	{ 1200000, 49, 0 },

	{ 1416000, 72, 0 },
	{ 1512000, 86, 0 },
};
The target frequency should be 1416000KHz, not 1512000KHz.

55fd7e0222 drm/i915: Include asm sources for {ivb, hsw}_clear_kernel.c
Alexandre Oliva has recently removed these files from Linux Libre
with concerns that the sources weren't available.

The sources are available on IGT repository, and only open source
tools are used to generate the {ivb,hsw}_clear_kernel.c files.

However, the remaining concern from Alexandre Oliva was around
GPL license and the source not been present when distributing
the code.

So, it looks like 2 alternatives are possible, the use of
linux-firmware.git repository to store the blob or making sure
that the source is also present in our tree. Since the goal
is to limit the i915 firmware to only the micro-controller blobs
let's make sure that we do include the asm sources here in our tree.

Btw, I tried to have some diligence here and make sure that the
asms that these commits are adding are truly the source for
the mentioned files:

register value last set by userland code by the thread that was active

was unmasked.

19ab500edb powerpc/mm/pkeys: Make pkey access check work on execute_only_key
Jan reported that LTP mmap03 was getting stuck in a page fault loop
after commit c46241a370 ("powerpc/pkeys: Check vma before returning
key fault error to the user"), as well as a minimised reproducer:

  #include <fcntl.h>
  #include <stdio.h>
  #include <stdlib.h>
  #include <unistd.h>
  #include <sys/mman.h>

  int main(int ac, char **av)
  {
  	int page_sz = getpagesize();
  	int fildes;
  	char *addr;

  	fildes = open("tempfile", O_WRONLY | O_CREAT, 0666);
  	write(fildes, &fildes, sizeof(fildes));
  	close(fildes);

  	fildes = open("tempfile", O_RDONLY);
  	unlink("tempfile");

  	addr = mmap(0, page_sz, PROT_EXEC, MAP_FILE | MAP_PRIVATE, fildes, 0);

  	printf("%d\n", *addr);
  	return 0;
  }

And noticed that access_pkey_error() in page fault handler now always
seem to return false:

  __do_page_fault
    access_pkey_error(is_pkey: 1, is_exec: 0, is_write: 0)
      arch_vma_access_permitted
	pkey_access_permitted
	  if (!is_pkey_enabled(pkey))
	    return true
      return false

pkey_access_permitted() should not check if the pkey is available in
UAMOR (using is_pkey_enabled()). The kernel needs to do that check
only when allocating keys. This also makes sure the execute_only_key
which is marked as non-manageable via UAMOR is handled correctly in
pkey_access_permitted(), and fixes the bug.

f7db192b2d ARM: OMAP fixes for v5.8
The OMAP developers are particularly active at hunting down regressions,
 so this is a separate branch with OMAP specific fixes for the v5.8:
 
 As Tony explains
  "The recent display subsystem (DSS) related platform data changes
   caused display related regressions for suspend and resume. Looks like
   I only tested suspend and resume before dropping the legacy platform
   data, and forgot to test it after dropping it. Turns out the main issue
   was that we no longer have platform code calling pm_runtime_suspend
   for DSS like we did for the legacy platform data case, and that fix
   is still being discussed on the dri-devel list and will get merged
   separately. The DSS related testing exposed a pile other other display
   related issues that also need fixing though":
 
  - Fix ti-sysc optional clock handling and reset status checks
    for devices that reset automatically in idle like DSS
 
  - Ignore ti-sysc clockactivity bit unless separately requested
    to avoid unexpected performance issues
 
  - Init ti-sysc framedonetv_irq to true and disable for am4
 
  - Avoid duplicate DSS reset for legacy mode with dts data
 
  - Remove LCD timings for am4 as they cause warnings now that we're
    using generic panels
 
 Other OMAP changes from Tony include:
 
  - Fix omap_prm reset deassert as we still have drivers setting the
    pm_runtime_irq_safe() flag
 
  - Flush posted write for ti-sysc enable and disable
 
  - Fix droid4 spi related errors with spi flags
 
  - Fix am335x USB range and a typo for softreset
 
  - Fix dra7 timer nodes for clocks for IPU and DSP
 
  - Drop duplicate mailboxes after mismerge for dra7
 
  - Prevent pocketgeagle header line signal from accidentally setting
    micro-SD write protection signal by removing the default mux
 
  - Fix NFSroot flakeyness after resume for duover by switching the
    smsc911x gpio interrupt to back to level sensitive
 
  - Fix regression for omap4 clockevent source after recent system
    timer changes
 
  - Yet another ethernet regression fix for the "rgmii" vs "rgmii-rxid"
    phy-mode
 
  - One patch to convert am3/am4 DT files to use the regular sdhci-omap
    driver instead of the old hsmmc driver, this was meant for the
    merge window but got lost in the process.

e21cf43406 sched/cfs: change initial value of runnable_avg
Some performance regression on reaim benchmark have been raised with
  commit 070f5e860e ("sched/fair: Take into account runnable_avg to classify group")

The problem comes from the init value of runnable_avg which is initialized
with max value. This can be a problem if the newly forked task is finally
a short task because the group of CPUs is wrongly set to overloaded and
tasks are pulled less agressively.

Set initial value of runnable_avg equals to util_avg to reflect that there
is no waiting time so far.

b6e13e8582 sched/core: Fix ttwu() race
Paul reported rcutorture occasionally hitting a NULL deref:

  sched_ttwu_pending()
    ttwu_do_wakeup()
      check_preempt_curr() := check_preempt_wakeup()
        find_matching_se()
          is_same_group()
            if (se->cfs_rq == pse->cfs_rq) <-- *BOOM*

Debugging showed that this only appears to happen when we take the new
code-path from commit:

  2ebb177175 ("sched/core: Offload wakee task activation if it the wakee is descheduling")

and only when @cpu == smp_processor_id(). Something which should not
be possible, because p->on_cpu can only be true for remote tasks.
Similarly, without the new code-path from commit:

  c6e7bd7afa ("sched/core: Optimize ttwu() spinning on p->on_cpu")

this would've unconditionally hit:

  smp_cond_load_acquire(&p->on_cpu, !VAL);

and if: 'cpu == smp_processor_id() && p->on_cpu' is possible, this
would result in an instant live-lock (with IRQs disabled), something
that hasn't been reported.

The NULL deref can be explained however if the task_cpu(p) load at the
beginning of try_to_wake_up() returns an old value, and this old value
happens to be smp_processor_id(). Further assume that the p->on_cpu
load accurately returns 1, it really is still running, just not here.

Then, when we enqueue the task locally, we can crash in exactly the
observed manner because p->se.cfs_rq != rq->cfs_rq, because p's cfs_rq
is from the wrong CPU, therefore we'll iterate into the non-existant
parents and NULL deref.

The closest semi-plausible scenario I've managed to contrive is
somewhat elaborate (then again, actual reproduction takes many CPU
hours of rcutorture, so it can't be anything obvious):

					X->cpu = 1
					rq(1)->curr = X

	CPU0				CPU1				CPU2

					// switch away from X
					LOCK rq(1)->lock
					smp_mb__after_spinlock
					dequeue_task(X)
					  X->on_rq = 9
					switch_to(Z)
					  X->on_cpu = 0
					UNLOCK rq(1)->lock

									// migrate X to cpu 0
									LOCK rq(1)->lock
									dequeue_task(X)
									set_task_cpu(X, 0)
									  X->cpu = 0
									UNLOCK rq(1)->lock

									LOCK rq(0)->lock
									enqueue_task(X)
									  X->on_rq = 1
									UNLOCK rq(0)->lock

	// switch to X
	LOCK rq(0)->lock
	smp_mb__after_spinlock
	switch_to(X)
	  X->on_cpu = 1
	UNLOCK rq(0)->lock

	// X goes sleep
	X->state = TASK_UNINTERRUPTIBLE
	smp_mb();			// wake X
					ttwu()
					  LOCK X->pi_lock
					  smp_mb__after_spinlock

					  if (p->state)

					  cpu = X->cpu; // =? 1

					  smp_rmb()

	// X calls schedule()
	LOCK rq(0)->lock
	smp_mb__after_spinlock
	dequeue_task(X)
	  X->on_rq = 0

					  if (p->on_rq)

					  smp_rmb();

					  if (p->on_cpu && ttwu_queue_wakelist(..)) [*]

					  smp_cond_load_acquire(&p->on_cpu, !VAL)

					  cpu = select_task_rq(X, X->wake_cpu, ...)
					  if (X->cpu != cpu)
	switch_to(Y)
	  X->on_cpu = 0
	UNLOCK rq(0)->lock

However I'm having trouble convincing myself that's actually possible
on x86_64 -- after all, every LOCK implies an smp_mb() there, so if ttwu
observes ->state != RUNNING, it must also observe ->cpu != 1.

(Most of the previous ttwu() races were found on very large PowerPC)

Nevertheless, this fully explains the observed failure case.

Fix it by ordering the task_cpu(p) load after the p->on_cpu load,
which is easy since nothing actually uses @cpu before this.

740797ce3a sched/core: Fix PI boosting between RT and DEADLINE tasks
syzbot reported the following warning:

 WARNING: CPU: 1 PID: 6351 at kernel/sched/deadline.c:628
 enqueue_task_dl+0x22da/0x38a0 kernel/sched/deadline.c:1504

At deadline.c:628 we have:

 623 static inline void setup_new_dl_entity(struct sched_dl_entity *dl_se)
 624 {
 625 	struct dl_rq *dl_rq = dl_rq_of_se(dl_se);
 626 	struct rq *rq = rq_of_dl_rq(dl_rq);
 627
 628 	WARN_ON(dl_se->dl_boosted);
 629 	WARN_ON(dl_time_before(rq_clock(rq), dl_se->deadline));
        [...]
     }

Which means that setup_new_dl_entity() has been called on a task
currently boosted. This shouldn't happen though, as setup_new_dl_entity()
is only called when the 'dynamic' deadline of the new entity
is in the past w.r.t. rq_clock and boosted tasks shouldn't verify this
condition.

Digging through the PI code I noticed that what above might in fact happen
if an RT tasks blocks on an rt_mutex hold by a DEADLINE task. In the
first branch of boosting conditions we check only if a pi_task 'dynamic'
deadline is earlier than mutex holder's and in this case we set mutex
holder to be dl_boosted. However, since RT 'dynamic' deadlines are only
initialized if such tasks get boosted at some point (or if they become
DEADLINE of course), in general RT 'dynamic' deadlines are usually equal
to 0 and this verifies the aforementioned condition.

Fix it by checking that the potential donor task is actually (even if
temporary because in turn boosted) running at DEADLINE priority before
using its 'dynamic' deadline value.

This happens because the ->dl_boosted flag is currently not initialized by
__dl_clear_params() (unlike the other flags) and setup_new_dl_entity()
rightfully complains about it.

Initialize dl_boosted to 0.

0f77ce26eb Revert "ARM: sti: Implement dummy L2 cache's write_sec"
This reverts commit 7b8e0188fa.

Initially, STiH410-B2260 was supposed to be secured, that's why
l2c_write_sec was stubbed to avoid secure register access from
non secure world.

But by default, STiH410-B2260 is running in non secure mode,
so L2 cache register accesses are authorized, l2c_write_sec stub
is not needed.

With this patch, L2 cache is configured and performance are enhanced.

8705ed2f72 Missed sdhci patch for am3 and am4
I forgot to send a pull request earlier for converting am3 and am4 to
 use sdhci-omap driver instead of the old omap_hsmmc driver.
 
 There was a display subsystem related suspend and resume regression found
 recently and looks like I forgot to send a pull request for this patch
 while debugging the regression. This patch has been tested without the
 display subsystem, and has been in Linux next for several weeks now, so
 would be good to have merged for v5.8.
