Nikolay Borisov 1d35b6054a scripts/bloat-o-meter: Support comparing library archives
Library archives (.a) usually contain multiple object files so their
output of nm --size-sort contains lines like:

<omitted for brevity>
00000000000003a8 t run_test

extent-map-tests.o:
<omitted for brevity>

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.

Ilias Stamatis 4ca1085c95 kthread: remove incorrect comment in kthread_create_on_cpu()
Originally kthread_create_on_cpu() parked and woke up the new thread.
However, since commit a65d40961d ("kthread/smpboot: do not park in
kthread_create_on_cpu()") this is no longer the case.  This patch removes
the comment that has been left behind and is now incorrect / stale.

Peter Zijlstra 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.

David Hildenbrand 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).

Fixes: e900a918b0 ("mm: shuffle initial free memory to improve memory-side-cache utilization")

 	- 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.

Linus Torvalds 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
  Oops: 0000 [#1] PREEMPT SMP

   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.

Linus Torvalds 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);

 "New xilinx displayport driver, AMD support for two new GPUs (more
  header files), i915 initial support for RocketLake and some work on

Linus Torvalds 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.

This problem is resolved by moving the call to mutex_init() up earlier
in nicvf_probe().

Oliver Neukum says:

====================
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

Oliver Neukum 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.

Linus Torvalds 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

On architectures defining _HAVE_ARCH_IPV6_CSUM, we get
csum_ipv6_magic() defined by means of arch checksum.h headers. On
other architectures, we actually need to include net/ip6_checksum.h
to be able to use it.

Without this include, building with defconfig breaks at least for
s390.

Willem de Bruijn 16f6458f24 selftests/net: relax cpu affinity requirement in msg_zerocopy test
The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.

But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.

The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.

Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

====================
selftests: rtnetlink: Fix for false-negative return values

This patchset will address the false-negative return value issue
caused by the following:
  1. The return value "ret" in this script will be reset to 0 from
     the beginning of each sub-test in rtnetlink.sh, therefore this
     rtnetlink test will always pass if the last sub-test has passed.
  2. The test result from two sub-tests in kci_test_encap() were not
     being processed, thus they will not affect the final test result
     of this test.

Po-Hsu Lin 72f70c159b selftests: rtnetlink: make kci_test_encap() return sub-test result
kci_test_encap() is actually composed by two different sub-tests,
kci_test_encap_vxlan() and kci_test_encap_fou()

Therefore we should check the test result of these two in
kci_test_encap() to let the script be aware of the pass / fail status.
Otherwise it will generate false-negative result like below:

Make "ret" become a local variable for all sub-tests.
Also, check the sub-test results in kci_test_rtnl() and return the
final result for this test.

Vladimir Oltean 0b0e299720 net: dsa: sja1105: use detected device id instead of DT one on mismatch
Although we can detect the chip revision 100% at runtime, it is useful
to specify it in the device tree compatible string too, because
otherwise there would be no way to assess the correctness of device tree
bindings statically, without booting a board (only some switch versions
have internal RGMII delays and/or an SGMII port).

But for testing the P/Q/R/S support, what I have is a reworked board
with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
want to keep a separate device tree blob just for this one-off board.
Since just the chip has been replaced, its RGMII delay setup is
inherently the same (meaning: delays added by the PHY on the slave
ports, and by PCB traces on the fixed-link CPU port).

For this board, I'd rather have the driver shout at me, but go ahead and
use what it found even if it doesn't match what it's been told is there.

[    2.970826] sja1105 spi0.1: Device tree specifies chip SJA1105T but found SJA1105Q, please fix it!
[    2.980010] sja1105 spi0.1: Probed switch chip: SJA1105Q

Xin Long 5a6f6f5791 tipc: set ub->ifindex for local ipv6 address
Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
ipv6_sock_mc_join() may make the wrong dev join the multicast
address in enable_mcast(). This causes that tipc links would
never be created.

So fix it by getting the right netdev and setting ub->ifindex,
as it does for ipv4 address.
