57c720d414 ocfs2: fix unbalanced locking
Based on what fails, function can return with nfs_sync_rwlock either
locked or unlocked. That can not be right.

Always return with lock unlocked on error.

Fixes: 4cd9973f9f ("ocfs2: avoid inode removal while nfsd is accessing it")

4510a5a98a ocfs2: replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `xmlns`:
        For each link, `http://[^# 	]*(?:\w|/)`:
	  If neither `gnu\.org/license`, nor `mozilla\.org/MPL`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

38d51b2dd1 ocfs2: change slot number type s16 to u16
Dan Carpenter reported the following static checker warning.

	fs/ocfs2/super.c:1269 ocfs2_parse_options() warn: '(-1)' 65535 can't fit into 32767 'mopt->slot'
	fs/ocfs2/suballoc.c:859 ocfs2_init_inode_steal_slot() warn: '(-1)' 65535 can't fit into 32767 'osb->s_inode_steal_slot'
	fs/ocfs2/suballoc.c:867 ocfs2_init_meta_steal_slot() warn: '(-1)' 65535 can't fit into 32767 'osb->s_meta_steal_slot'

That's because OCFS2_INVALID_SLOT is (u16)-1. Slot number in ocfs2 can be
never negative, so change s16 to u16.

1146f7e2dc ntfs: fix ntfs_test_inode and ntfs_init_locked_inode function type
Clang's Control Flow Integrity (CFI) is a security mechanism that can help
prevent JOP chains, deployed extensively in downstream kernels used in
Android.

Its deployment is hindered by mismatches in function signatures.  For this
case, we make callbacks match their intended function signature, and cast
parameters within them rather than casting the callback when passed as a
parameter.

When running `mount -t ntfs ...` we observe the following trace:

bloat-o-meter currently doesn't handle them which results in errors when
calling .split() on them.  Fix this by simply ignoring them.  This enables
diffing subsystems which generate built-in.a files.

38cf307c1f mm: fix kthread_use_mm() vs TLB invalidate
For SMP systems using IPI based TLB invalidation, looking at
current->active_mm is entirely reasonable.  This then presents the
following race condition:

  CPU0			CPU1

  flush_tlb_mm(mm)	use_mm(mm)
    <send-IPI>
			  tsk->active_mm = mm;
			  <IPI>
			    if (tsk->active_mm == mm)
			      // flush TLBs
			  </IPI>
			  switch_mm(old_mm,mm,tsk);

Where it is possible the IPI flushed the TLBs for @old_mm, not @mm,
because the IPI lands before we actually switched.

Avoid this by disabling IRQs across changing ->active_mm and
switch_mm().

Of the (SMP) architectures that have IPI based TLB invalidate:

  Alpha    - checks active_mm
  ARC      - ASID specific
  IA64     - checks active_mm
  MIPS     - ASID specific flush
  OpenRISC - shoots down world
  PARISC   - shoots down world
  SH       - ASID specific
  SPARC    - ASID specific
  x86      - N/A
  xtensa   - checks active_mm

So at the very least Alpha, IA64 and Xtensa are suspect.

On top of this, for scheduler consistency we need at least preemption
disabled across changing tsk->mm and doing switch_mm(), which is
currently provided by task_lock(), but that's not sufficient for
PREEMPT_RT.

4a93025cbe mm/shuffle: don't move pages between zones and don't read garbage memmaps
Especially with memory hotplug, we can have offline sections (with a
garbage memmap) and overlapping zones.  We have to make sure to only touch
initialized memmaps (online sections managed by the buddy) and that the
zone matches, to not move pages between zones.

To test if this can actually happen, I added a simple

	BUG_ON(page_zone(page_i) != page_zone(page_j));

right before the swap.  When hotplugging a 256M DIMM to a 4G x86-64 VM and
onlining the first memory block "online_movable" and the second memory
block "online_kernel", it will trigger the BUG, as both zones (NORMAL and
MOVABLE) overlap.

This might result in all kinds of weird situations (e.g., double
allocations, list corruptions, unmovable allocations ending up in the
movable zone).

c0c419c045 Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1.
 
 Lots of churn here, but overall the size increase in lines added is
 small, while adding a load of new IIO drivers.
 
 Major things in here:
 	- lots and lots of IIO new drivers and frameworks added
 	- IIO driver fixes and updates
 	- lots of tiny coding style cleanups for staging drivers
 	- vc04_services major reworks and cleanups
 
 We had 3 set of drivers move out of staging in this round as well:
 	- wilc1000 wireless driver moved out of staging
 	- speakup moved out of staging
 	- most USB driver moved out of staging
 
 Full details are in the shortlog.
 
 All of these have been in linux-next with no reported issues.  The last
 few changes here were to resolve reported linux-next issues, and they
 seem to have resolved the problems.

7b4ea9456d Revert "x86/mm/64: Do not sync vmalloc/ioremap mappings"
This reverts commit 8bb9bf242d.

It seems the vmalloc page tables aren't always preallocated in all
situations, because Jason Donenfeld reports an oops with this commit:

  BUG: unable to handle page fault for address: ffffe8ffffd00608
  #PF: supervisor read access in kernel mode
  #PF: error_code(0x0000) - not-present page
  PGD 0 P4D 0

   ? __kthread_create_worker+0x110/0x110
   ret_from_fork+0x1f/0x30
  CR2: ffffe8ffffd00608

and that page fault address is right in that vmalloc space, and we
clearly don't have a PGD/P4D entry for it.

Looking at the "Code:" line, the actual fault seems to come from the
'pwq->wq' dereference at the top of the process_one_work() function:

        struct pool_workqueue *pwq = get_work_pwq(work);
        struct worker_pool *pool = worker->pool;
        bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE;

so 'struct pool_workqueue *pwq' is the allocation that hasn't been
synchronized across CPUs.

Just revert for now, while Joerg figures out the cause.

6d2b84a4e5 This tree adds the sched_set_fifo*() encapsulation APIs to remove
static priority level knowledge from non-scheduler code.
 
 The three APIs for non-scheduler code to set SCHED_FIFO are:
 
  - sched_set_fifo()
  - sched_set_fifo_low()
  - sched_set_normal()
 
 These are two FIFO priority levels: default (high), and a 'low' priority level,
 plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
 
 Since the changes affect a lot of non-scheduler code, we kept this in a separate
 tree.
 
 When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
 which can be resolved via:
 
 	sched_set_fifo(ctlr->kworker_task);

Pull drm updates from Dave Airlie:
 "New xilinx displayport driver, AMD support for two new GPUs (more
  header files), i915 initial support for RocketLake and some work on
  their DG1 (discrete chip).

  The core also grew some lockdep annotations to try and constrain what
  drivers do with dma-fences, and added some documentation on why the
  idea of indefinite fences doesn't work.

  The long list is below.

e4a7b2dc35 LEDs changes for 5.9-rc1.
Okay, so... this one is interesting. RGB LEDs are very common, and we
 need to have some kind of support for them. Multicolor is for
 arbitrary set of LEDs in one package, RGB is for LEDs that can produce
 full range of colors. We do not have real multicolor LED that is not
 RGB in the pipeline, so that one is disabled for now.
 
 You can expect this saga to continue with next pull requests.

====================
misc bug fixes for the hso driver

1. Code reuse led to an unregistration of a net driver that has not been
registered
2. The kernel complains generically if kmalloc with GFP_KERNEL fails
3. A race that can lead to an URB that is in use being reused or
a use after free

5fcfb6d0bf hso: fix bailout in error case of probe
The driver tries to reuse code for disconnect in case
of a failed probe.
If resources need to be freed after an error in probe, the
netdev must not be freed because it has never been registered.
Fix it by telling the helper which path we are in.

Before switch from discontigmem to sparsemem, there always was
CONFIG_NEED_MULTIPLE_NODES=y because it was selected by DISCONTIGMEM.
Without DISCONTIGMEM it is possible to have SPARSEMEM without NUMA for
SGI_IP27 and as many things there rely on custom node definition, the
build breaks.

As Thomas noted "... there are right now too many places in IP27 code,
which assumes NUMA enabled", the simplest solution would be to always
enable NUMA for SGI-IP27 builds.

fffe3ae0ee hmm related patches for 5.9
This series adds reporting of the page table order from hmm_range_fault()
 and some optimization of migrate_vma():
 
 - Report the size of the page table mapping out of hmm_range_fault(). This
   makes it easier to establish a large/huge/etc mapping in the device's
   page table.
 
 - Allow devices to ignore the invalidations during migration in cases
   where the migration is not going to change pages. For instance migrating
   pages to a device does not require the device to invalidate pages
   already in the device.
 
 - Update nouveau and hmm_tests to use the above
