99b142cf71 remoteproc: imx_rproc: Request mbox channel later
It is possible that when remote processor crash, the communication
channel will be broken with garbage value in mailbox, such as
when Linux is issuing a message through mailbox, remote processor
crashes, we need free & rebuild the mailbox channels to make sure
no garbage value in mailbox channels.

So move the request/free to start/stop for managing remote procesosr in
Linux, move to attach/detach for remote processor is out of control of
Linux.

Previous, we just request mbox when attach for CM4 boot early before
Linux, but if mbox defer probe, remoteproc core will do resource cleanup
and corrupt resource table for later probe.

So move request mbox ealier and still keep mbox request when attach
for self recovery case, but keep a check when request/free mbox.

When M4 is in the same hardware partition with Cortex-A, it

47e6ab0701 remoteproc: imx_dsp_rproc: Add mutex protection for workqueue
The workqueue may execute late even after remoteproc is stopped or
stopping, some resources (rpmsg device and endpoint) have been
released in rproc_stop_subdevices(), then rproc_vq_interrupt()
accessing these resources will cause kennel dump.

 ret_from_fork+0x10/0x20

Add mutex protection in imx_dsp_rproc_vq_work(), if the state is
not running, then just skip calling rproc_vq_interrupt().

Also the flush workqueue operation can't be added in rproc stop
for the same reason. The call sequence is

rproc_shutdown
-> rproc_stop
   ->rproc_stop_subdevices
   ->rproc->ops->stop()
     ->imx_dsp_rproc_stop
       ->flush_work
         -> rproc_vq_interrupt

The resource needed by rproc_vq_interrupt has been released in
rproc_stop_subdevices, so flush_work is not safe to be called in
imx_dsp_rproc_stop.

9440c42941 x86/syscall: Include asm/ptrace.h in syscall_wrapper header
With just the forward declaration of the 'struct pt_regs' in
syscall_wrapper.h, the syscall stub functions:

  __[x64|ia32]_sys_*(struct pt_regs *regs)

will have different definition of 'regs' argument in BTF data
based on which object file they are defined in.

If the syscall's object includes 'struct pt_regs' definition,
the BTF argument data will point to a 'struct pt_regs' record,
like:

  [226] STRUCT 'pt_regs' size=168 vlen=21
         'r15' type_id=1 bits_offset=0
         'r14' type_id=1 bits_offset=64
         'r13' type_id=1 bits_offset=128
  ...

If not, it will point to a fwd declaration record:

  [15439] FWD 'pt_regs' fwd_kind=struct

and make bpf tracing program hooking on those functions unable
to access fields from 'struct pt_regs'.

Include asm/ptrace.h directly in syscall_wrapper.h to make sure all
syscalls see 'struct pt_regs' definition. This then results in BTF for
'__*_sys_*(struct pt_regs *regs)' functions to point to the actual
struct, not just the forward declaration.

  [ bp: No Fixes tag as this is not really a bug fix but "adjustment" so
    that BTF is happy. ]

The cause of the issue is that brelse() is called on both ofibh.sbh
and ofibh.ebh by udf_find_entry() when it returns NULL.  However,
brelse() is called by udf_rename(), too.  So, b_count on buffer_head
becomes unbalanced.

This patch fixes the issue by not calling brelse() by udf_rename()
when udf_find_entry() returns NULL.

0d2aa70b8f apei/ghes: Use xchg_release() for updating new cache slot instead of cmpxchg()
Some documentation first, about how this machinery works:

It seems, the intent of the GHES error records cache is to collect
already reported errors - see the ghes_estatus_cached() checks. There's
even a sentence trying to say what this does:

  /*
   * GHES error status reporting throttle, to report more kinds of
   * errors, instead of just most frequently occurred errors.
   */

New elements are added to the cache this way:

  if (!ghes_estatus_cached(estatus)) {
          if (ghes_print_estatus(NULL, ghes->generic, estatus))
                  ghes_estatus_cache_add(ghes->generic, estatus);

The intent being, once this new error record is reported, it gets cached
so that it doesn't get reported for a while due to too many, same-type
error records getting reported in burst-like scenarios. I.e., new,
unreported error types can have a higher chance of getting reported.

Now, the loop in ghes_estatus_cache_add() is trying to pick out the
oldest element in there. Meaning, something which got reported already
but a long while ago, i.e., a LRU-type scheme.

And the cmpxchg() is there presumably to make sure when that selected
element slot_cache is removed, it really *is* that element that gets
removed and not one which replaced it in the meantime.

Now, ghes_estatus_cache_add() selects a slot, and either succeeds in
replacing its contents with a pointer to a newly cached item, or it just
gives up and frees the new item again, without attempting to select
another slot even if one might be available.

Since only inserting new items is being done here, the race can only
cause a failure if the selected slot was updated with another new item
concurrently, which means that it is arbitrary which of those two items
gets dropped.

And "dropped" here means, the item doesn't get added to the cache so
the next time it is seen, it'll get reported again and an insertion
attempt will be done again. Eventually, it'll get inserted and all those
times when the insertion fails, the item will get reported although the
cache is supposed to prevent that and "ratelimit" those repeated error
records. Not a big deal in any case.

This means the cmpxchg() and the special case are not necessary.
Therefore, just drop the existing item unconditionally.

Move the xchg_release() and call_rcu() out of rcu_read_lock/unlock
section since there is no actually dereferencing the pointer at all.

  [ bp:
    - Flesh out and summarize what was discussed on the thread now
      that that cache contraption is understood;
    - Touch up code style. ]

bc29d5bd2b mm/slub: perform free consistency checks before call_rcu
For SLAB_TYPESAFE_BY_RCU caches we use call_rcu to perform empty slab
freeing. The rcu callback rcu_free_slab() calls __free_slab() that
currently includes checking the slab consistency for caches with
SLAB_CONSISTENCY_CHECKS flags. This check needs the slab->objects field
to be intact.

Because in the next patch we want to allow rcu_head in struct slab to
become larger in debug configurations and thus potentially overwrite
more fields through a union than slab_list, we want to limit the fields
used in rcu_free_slab().  Thus move the consistency checks to
free_slab() before call_rcu(). This can be done safely even for
SLAB_TYPESAFE_BY_RCU caches where accesses to the objects can still
occur after freeing them.

As a result, only the slab->slab_cache field has to be physically
separate from rcu_head for the freeing callback to work. We also save
some cycles in the rcu callback for caches with consistency checks
enabled.

0dafb7e671 fs: udf: Optimize udf_free_in_core_inode and udf_find_fileset function
These two functions perform the following optimizations.
1. Delete the type cast of foo pointer. Void * does not need to convert
the type.
2. Delete the initialization assignment of bh variable, which is
assigned first.

spi: pxa2xx: Pass the SSP type via device property
Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:

Currently the SPI PXA2xx devices on Intel platforms can be instantiated
via the following paths:
 1) as ACPI LPSS device on Haswell, Bay Trail and Cherry Trail;
 2) as ACPI LPSS device on the Sky Lake and newer;
 3) as PCI LPSS device on Haswell, Bay Trail and Cherry Trail;
 4) as PCI LPSS device on the Sky Lake and newer;
 5) as PCI device via ID table.

Each of these cases provides some platform related data differently,
i.e.:
 1) via drivers/acpi/acpi_lpss.c and drivers/spi/spi-pxa2xx.c
 2) via drivers/mfd/intel-lpss-acpi.c
 3) via drivers/spi/spi-pxa2xx-pci.c
 4) via drivers/mfd/intel-lpss-pci.c and drivers/spi/spi-pxa2xx.c
 5) via drivers/spi/spi-pxa2xx-pci.c

This approach has two downsides:

a) there is no data propagated in the case #2 because we can't have
   two or more drivers to match the same ACPI ID and hence some cases
   are still not supported (Sky Lake and newer ACPI enabled LPSS);

b) the data is duplicated over two drivers in the cases #1 & #4 and,
   besides to be a bloatware, it is error prone (e.g. Lakefield has
   a wrong data right now due to missed PCI entry in the spi-pxa2xx.c).

This series fixes the downsides, and enables previously unsupported
cases.

e5530adc17 pinctrl: Clean up headers
There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically

While at it, fix some awkward indentations.
