Commit d96c3600 ("tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig
entry") removed a hidden tab because it apparently showed breakage in
some third-party kernel config parsing tool.

It wasn't clear what tool it was, but let's make sure it gets fixed.
Because if you can't parse tabs as whitespace, you should not be parsing
the kernel Kconfig files.

In fact, let's make such breakage more obvious than some esoteric ftrace
record size option.  If you can't parse tabs, you can't have page sizes.

Yes, tab-vs-space confusion is sadly a traditional Unix thing, and
'make' is famous for being broken in this regard.  But no, that does not
mean that it's ok.

I'd add more random tabs to our Kconfig files, but I don't want to make
things uglier than necessary.  But it *might* bbe necessary if it turns
out we see more of this kind of silly tooling.

Pull tracing fixes from Steven Rostedt:

 - Fix the buffer_percent accounting as it is dependent on three
   variables:

     1) pages_read - number of subbuffers read
     2) pages_lost - number of subbuffers lost due to overwrite
     3) pages_touched - number of pages that a writer entered

   These three counters only increment, and to know how many active
   pages there are on the buffer at any given time, the pages_read and
   pages_lost are subtracted from pages_touched.

   But the pages touched was incremented whenever any writer went to the
   next subbuffer even if it wasn't the only one, so it was incremented
   more than it should be causing the counter for how many subbuffers
   currently have content incorrect, which caused the buffer_percent
   that holds waiters until the ring buffer is filled to a given
   percentage to wake up early.

While monitoring the throttle time of IO from iocost, it's found that
such time is always zero after the io_schedule() from ioc_rqos_throttle,
for example, with the following debug patch:

+       printk("%s-%d: %s enter %llu\n", current->comm, current->pid, __func__, blk_time_get_ns());
        while (true) {
                set_current_state(TASK_UNINTERRUPTIBLE);
                if (wait.committed)
                        break;
                io_schedule();
        }
+       printk("%s-%d: %s exit  %llu\n", current->comm, current->pid, __func__, blk_time_get_ns());

It can be observerd that blk_time_get_ns() always return the same time:

[ 1068.096579] fio-1268: ioc_rqos_throttle enter 1067901962288
[ 1068.272587] fio-1268: ioc_rqos_throttle exit  1067901962288
[ 1068.274389] fio-1268: ioc_rqos_throttle enter 1067901962288
[ 1068.472690] fio-1268: ioc_rqos_throttle exit  1067901962288
[ 1068.474485] fio-1268: ioc_rqos_throttle enter 1067901962288
[ 1068.672656] fio-1268: ioc_rqos_throttle exit  1067901962288
[ 1068.674451] fio-1268: ioc_rqos_throttle enter 1067901962288
[ 1068.872655] fio-1268: ioc_rqos_throttle exit  1067901962288

And I think the root cause is that 'PF_BLOCK_TS' is always cleared
by blk_flush_plug() before scheduel(), hence blk_plug_invalidate_ts()
will never be called:

blk_time_get_ns
 plug->cur_ktime = ktime_get_ns();
 current->flags |= PF_BLOCK_TS;

io_schedule:
 io_schedule_prepare
  blk_flush_plug
   __blk_flush_plug
    /* the flag is cleared, while time is not */
    current->flags &= ~PF_BLOCK_TS;
 schedule
 sched_update_worker
  /* the flag is not set, hence plug->cur_ktime is not cleared */
  if (tsk->flags & PF_BLOCK_TS)
   blk_plug_invalidate_ts()

blk_time_get_ns
 /* got the time stashed before schedule */
 return plug->cur_ktime;

Fix the problem by clearing cached time in __blk_flush_plug().

Commit 1a75cc71 ("iommu/vt-d: Use rbtree to track iommu probed
devices") adds all devices probed by the iommu driver in a rbtree
indexed by the source ID of each device. It assumes that each device
has a unique source ID. This assumption is incorrect and the VT-d
spec doesn't state this requirement either.

The reason for using a rbtree to track devices is to look up the device
with PCI bus and devfunc in the paths of handling ATS invalidation time
out error and the PRI I/O page faults. Both are PCI ATS feature related.

Only track the devices that have PCI ATS capabilities in the rbtree to
avoid unnecessary WARN_ON in the iommu probe path. Otherwise, on some
platforms below kernel splat will be displayed and the iommu probe results
in failure.

DTE[Mode]=0 is not supported when SNP is enabled in the host. That means
to support SNP, IOMMU must be configured with V1 page table (See IOMMU
spec [1] for the details). If user passes kernel command line to configure
IOMMU domains with v2 page table (amd_iommu=pgtbl_v2) then disable SNP
as the user asked by not forcing the page table to v1.

Fixes for v6.9

Display:
- Fixes for PM refcount leak when DP goes to disconnected state and
  also when link training fails. This is also one of the issues found
  with the pm runtime series
- Add missing newlines to prints in msm_fb and msm_kms
- Change permissions of some dpu debugfs entries which write to const
  data from catalog to read-only to avoid protection faults
- Fix the interface table for the catalog of X1E80100. This is an
  important fix to bringup DP for X1E80100.
- Logging fix to print the callback symbol in the invalid IRQ message
  case rather than printing when its known to be NULL.
- Bindings fix to add DP node as child of mdss for mdss node
- Minor typo fix in DP driver API which handles port status change

GPU:
- fix CHRASHDUMP_READ()
- fix HHB (highest bank bit) for a619 to fix UBWC corruption

The "buffer_percent" logic that is used by the ring buffer splice code to
only wake up the tasks when there's no data after the buffer is filled to
the percentage of the "buffer_percent" file is dependent on three
variables that determine the amount of data that is in the ring buffer:

 1) pages_read - incremented whenever a new sub-buffer is consumed
 2) pages_lost - incremented every time a writer overwrites a sub-buffer
 3) pages_touched - incremented when a write goes to a new sub-buffer

The percentage is the calculation of:

  (pages_touched - (pages_lost + pages_read)) / nr_pages

Basically, the amount of data is the total number of sub-bufs that have been
touched, minus the number of sub-bufs lost and sub-bufs consumed. This is
divided by the total count to give the buffer percentage. When the
percentage is greater than the value in the "buffer_percent" file, it
wakes up splice readers waiting for that amount.

It was observed that over time, the amount read from the splice was
constantly decreasing the longer the trace was running. That is, if one
asked for 60%, it would read over 60% when it first starts tracing, but
then it would be woken up at under 60% and would slowly decrease the
amount of data read after being woken up, where the amount becomes much
less than the buffer percent.

This was due to an accounting of the pages_touched incrementation. This
value is incremented whenever a writer transfers to a new sub-buffer. But
the place where it was incremented was incorrect. If a writer overflowed
the current sub-buffer it would go to the next one. If it gets preempted
by an interrupt at that time, and the interrupt performs a trace, it too
will end up going to the next sub-buffer. But only one should increment
the counter. Unfortunately, that was not the case.

Change the cmpxchg() that does the real switch of the tail-page into a
try_cmpxchg(), and on success, perform the increment of pages_touched. This
will only increment the counter once for when the writer moves to a new
sub-buffer, and not when there's a race and is incremented for when a
writer and its preempting writer both move to the same new sub-buffer.

There are various use cases that are becoming more common in which password
changes are scheduled on a server(s) periodically but the clients connected
to this server need to stay connected (even in the face of brief network
reconnects) due to mounts which can not be easily unmounted and mounted at
will, and servers that do password rotation do not always have the ability
to tell the clients exactly when to the new password will be effective,
so add support for an alt password ("password2=") on mount (and also
remount) so that we can anticipate the upcoming change to the server
without risking breaking existing mounts.

An alternative would have been to use the kernel keyring for this but the
processes doing the reconnect do not have access to the keyring but do
have access to the ses structure.
