By simply bailing out, the driver was violating its rule and internal

this could cause the first core to be available but not the second one,
leading to crashes on its shutdown later on while trying to dereference
that second instance.

On some NXP platforms (e.g i.MX7ULP) the poweroff and reboot operations
are done via a separate remote core.

Typically Linux needs to send a message to the remote core and requests
for poweroff or reboot.

By default the communication between Linux core and the remote core is
is done via a blocking mailbox mechanism but Linux doesn't allow blocking
operations in the system off (reboot, power off) handlers.

So, we need to make sure the mailbox message send operations do not block
for this specific operations. Fortunately, Linux allows us to register
handlers that are called in preparation of the system off operations.

Thus, before carrying the power off or reboot preparations, just destroy
the existing mailboxes and create them as non-blocking.

Note that power off and restart are totally different operations and are
not complementary.

We introduce a new flag in the imx remoteproc per device data which tells
us when a device needs this special setup. For now, only imx7ulp needs it.

The AM62x and AM64x SoCs of the TI K3 family has a Cortex M4F core in
the MCU domain. This core is typically used for safety applications in a
stand alone mode. However, some application (non safety related) may
want to use the M4F core as a generic remote processor with IPC to the
host processor. The M4F core has internal IRAM and DRAM memories and are
exposed to the system bus for code and data loading.

A remote processor driver is added to support this subsystem, including
being able to load and boot the M4F core. Loading includes to M4F
internal memories and predefined external code/data memories. The
carve outs for external contiguous memory is defined in the M4F device
node and should match with the external memory declarations in the M4F
image binary. The M4F subsystem has two resets. One reset is for the
entire subsystem i.e including the internal memories and the other, a
local reset is only for the M4F processing core. When loading the image,
the driver first releases the subsystem reset, loads the firmware image
and then releases the local reset to let the M4F processing core run.

This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.

That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

Commit 3a7e02c0 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.

The complexity of those macros stems from two issues:

 (a) trying to use them in situations that require a C constant
     expression (in static initializers and for array sizes)

 (b) the type sanity checking

and MIN_T/MAX_T avoids both of these issues.

Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.

But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.

However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.

This does exactly that.

Which in turn will then allow for much simpler implementations of
min_t()/max_t().  All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.

We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:

  $ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
  clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]

This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.

'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.

All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

Pull vfs fixes from Christian Brauner:
 "This contains two fixes for this merge window:

  VFS:

   - I noticed that it is possible for a privileged user to mount most
     filesystems with a non-initial user namespace in sb->s_user_ns.

     When fsopen() is called in a non-init namespace the caller's
     namespace is recorded in fs_context->user_ns. If the returned file
     descriptor is then passed to a process privileged in init_user_ns,
     that process can call fsconfig(fd_fs, FSCONFIG_CMD_CREATE*),
     creating a new superblock with sb->s_user_ns set to the namespace
     of the process which called fsopen().

     This is problematic as only filesystems that raise FS_USERNS_MOUNT
     are known to be able to support a non-initial s_user_ns. Others may
     suffer security issues, on-disk corruption or outright crash the
     kernel. Prevent that by restricting such delegation to filesystems
     that allow FS_USERNS_MOUNT.

     Note, that this delegation requires a privileged process to
     actually create the superblock so either the privileged process is
     cooperaing or someone must have tricked a privileged process into
     operating on a fscontext file descriptor whose origin it doesn't
     know (a stupid idea).

     The bug dates back to about 5 years afaict.

  Misc:

   - Fix hostfs parsing when the mount request comes in via the legacy
     mount api.

     In the legacy mount api hostfs allows to specify the host directory
     mount without any key.

     Restore that behavior"

* tag 'vfs-6.11-rc1.fixes.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  hostfs: fix the host directory parse when mounting.
  fs: don't allow non-init s_user_ns for filesystems without FS_USERNS_MOUNT
