3361b9c4ed media: adv748x: Store the source subdevice in TX
The power_up_tx() procedure needs to set a few registers conditionally to
the selected video source, but it currently checks for the provided tx to
be either TXA or TXB.

With the introduction of dynamic routing between HDMI and AFE entities to
TXA, checking which TX the function is operating on is not meaningful anymore.

To fix this, store the subdevice of the source providing video data to the
CSI-2 TX in the 'struct adv748x_csi2' representing the TX and check on it.

21325e19ca media: adv748x: csi2: Link AFE with TXA and TXB
The ADV748x chip supports routing AFE output to either TXA or TXB.
In order to support run-time configuration of video stream path, create an
additional (not enabled) "AFE:8->TXA:0" link, and remove the IMMUTABLE flag
from existing ones.

3d769df5fc media: v4l2-subdev.h: v4l2_subdev_call: use temp __sd variable
The sd argument of this macro can be a more complex expression. Since it
is used 5 times in the macro it can be evaluated that many times as well.

So assign it to a temp variable in the beginning and use that instead.

This also avoids any potential side-effects of evaluating sd.

5964cbd869 media: imx: Set capture compose rectangle in capture_device_set_format
The capture compose rectangle was not getting updated when setting
the source subdevice's source pad format. This causes the compose window
to be zero (or not updated) at stream start unless the capture device
format was set explicitly at the capture device node.

Fix by moving the calculation of the capture compose rectangle to
imx_media_mbus_fmt_to_pix_fmt(), and pass the rectangle to
imx_media_capture_device_set_format().

14c8e80e68 media: v4l: ioctl: Sanitize num_planes before using it
The linked commit changed s_fmt/try_fmt to fail if num_planes is bogus.
This, however, is against the spec, which mandates drivers
to return a proper num_planes value, without an error.

Replace the num_planes check and instead clamp it to a sane value,
so we still make sure we don't overflow the planes array by accident.

a58007621b powerpc/64s: Fix possible corruption on big endian due to pgd/pud_present()
In v4.20 we changed our pgd/pud_present() to check for _PAGE_PRESENT
rather than just checking that the value is non-zero, e.g.:

  static inline int pgd_present(pgd_t pgd)
  {
 -       return !pgd_none(pgd);
 +       return (pgd_raw(pgd) & cpu_to_be64(_PAGE_PRESENT));
  }

Unfortunately this is broken on big endian, as the result of the
bitwise & is truncated to int, which is always zero because
_PAGE_PRESENT is 0x8000000000000000ul. This means pgd_present() and
pud_present() are always false at compile time, and the compiler
elides the subsequent code.

Remarkably with that bug present we are still able to boot and run
with few noticeable effects. However under some work loads we are able

8a5b403d71 arm64, mm, efi: Account for GICv3 LPI tables in static memblock reserve table
In the irqchip and EFI code, we have what basically amounts to a quirk
to work around a peculiarity in the GICv3 architecture, which permits
the system memory address of LPI tables to be programmable only once
after a CPU reset. This means kexec kernels must use the same memory
as the first kernel, and thus ensure that this memory has not been
given out for other purposes by the time the ITS init code runs, which
is not very early for secondary CPUs.

On systems with many CPUs, these reservations could overflow the
memblock reservation table, and this was addressed in commit:

  eff8962888 ("efi/arm: Defer persistent reservations until after paging_init()")

However, this turns out to have made things worse, since the allocation
of page tables and heap space for the resized memblock reservation table
itself may overwrite the regions we are attempting to reserve, which may
cause all kinds of corruption, also considering that the ITS will still
be poking bits into that memory in response to incoming MSIs.

So instead, let's grow the static memblock reservation table on such
systems so it can accommodate these reservations at an earlier time.
This will permit us to revert the above commit in a subsequent patch.

e7afe6c1d4 sunrpc: fix 4 more call sites that were using stack memory with a scatterlist
While trying to reproduce a reported kernel panic on arm64, I discovered
that AUTH_GSS basically doesn't work at all with older enctypes on arm64
systems with CONFIG_VMAP_STACK enabled.  It turns out there still a few
places using stack memory with scatterlists, causing krb5_encrypt() and
krb5_decrypt() to produce incorrect results (or a BUG if CONFIG_DEBUG_SG
is enabled).

Tested with cthon on v4.0/v4.1/v4.2 with krb5/krb5i/krb5p using
des3-cbc-sha1 and arcfour-hmac-md5.

a6e60d8498 include/linux/module.h: copy __init/__exit attrs to init/cleanup_module
The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target.

In particular, it triggers for all the init/cleanup_module
aliases in the kernel (defined by the module_init/exit macros),
ending up being very noisy.

These aliases point to the __init/__exit functions of a module,
which are defined as __cold (among other attributes). However,
the aliases themselves do not have the __cold attribute.

Since the compiler behaves differently when compiling a __cold
function as well as when compiling paths leading to calls
to __cold functions, the warning is trying to point out
the possibly-forgotten attribute in the alias.

In order to keep the warning enabled, we decided to silence
this case. Ideally, we would mark the aliases directly
as __init/__exit. However, there are currently around 132 modules
in the kernel which are missing __init/__exit in their init/cleanup
functions (either because they are missing, or for other reasons,
e.g. the functions being called from somewhere else); and
a section mismatch is a hard error.

A conservative alternative was to mark the aliases as __cold only.
However, since we would like to eventually enforce __init/__exit
to be always marked,  we chose to use the new __copy function
attribute (introduced by GCC 9 as well to deal with this).
With it, we copy the attributes used by the target functions
into the aliases. This way, functions that were not marked
as __init/__exit won't have their aliases marked either,
and therefore there won't be a section mismatch.

Note that the warning would go away marking either the extern
declaration, the definition, or both. However, we only mark
the definition of the alias, since we do not want callers
(which only see the declaration) to be compiled as if the function
was __cold (and therefore the paths leading to those calls
would be assumed to be unlikely).

c0d9782f5b Compiler Attributes: add support for __copy (gcc >= 9)
From the GCC manual:

  copy
  copy(function)

    The copy attribute applies the set of attributes with which function
    has been declared to the declaration of the function to which
    the attribute is applied. The attribute is designed for libraries
    that define aliases or function resolvers that are expected
    to specify the same set of attributes as their targets. The copy
    attribute can be used with functions, variables, or types. However,
    the kind of symbol to which the attribute is applied (either
    function or variable) must match the kind of symbol to which
    the argument refers. The copy attribute copies only syntactic and
    semantic attributes but not attributes that affect a symbol’s
    linkage or visibility such as alias, visibility, or weak.
    The deprecated attribute is also not copied.

  https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html

The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target, e.g.:

    void __cold f(void) {}
    void __alias("f") g(void);

diagnoses:

    warning: 'g' specifies less restrictive attribute than
    its target 'f': 'cold' [-Wmissing-attributes]

Using __copy(f) we can copy the __cold attribute from f to g:

    void __cold f(void) {}
    void __copy(f) __alias("f") g(void);

This attribute is most useful to deal with situations where an alias
is declared but we don't know the exact attributes the target has.

For instance, in the kernel, the widely used module_init/exit macros
define the init/cleanup_module aliases, but those cannot be marked
always as __init/__exit since some modules do not have their
functions marked as such.

ff98e20ef2 lib/crc32.c: mark crc32_le_base/__crc32c_le_base aliases as __pure
The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target.

In particular, it triggers here because crc32_le_base/__crc32c_le_base
aren't __pure while their target crc32_le/__crc32c_le are.

These aliases are used by architectures as a fallback in accelerated
versions of CRC32. See commit 9784d82db3 ("lib/crc32: make core crc32()
routines weak so they can be overridden").

Therefore, being fallbacks, it is likely that even if the aliases
were called from C, there wouldn't be any optimizations possible.
Currently, the only user is arm64, which calls this from asm.

Still, marking the aliases as __pure makes sense and is a good idea
for documentation purposes and possible future optimizations,
which also silences the warning.

69ef9bc547 auxdisplay: ht16k33: fix potential user-after-free on module unload
On module unload/remove, we need to ensure that work does not run
after we have freed resources. Concretely, cancel_delayed_work()
may return while the callback function is still running.

From kernel/workqueue.c:

    The work callback function may still be running on return,
    unless it returns true and the work doesn't re-arm itself.
    Explicitly flush or use cancel_delayed_work_sync() to wait on it.

2ed5c2e3f2 SoC fixes for omaps for v5.0-rc cycle
This series contains two SoC regression fixes and one uninitialized
 variable fix:
 
 - Fix inverted nirq pin handling for omap5 that started producing
   warnings with earlier GIC direction checks and took a while to
   understand and confirm. Basically there are two sys_nirq pins
   that are bypassing peripheral modules and inverted automatically
   by the SoC and need to be handled with a custom irq_set_type()
 
 - Recent ti-sysc changes caused a regression to the pwm-omap-dmtimer
   code where the device tree handling code for timer source clock
   gets confused. It looks like we can remove that code eventually,
   but for now we just drop a bogus pm_runtime_irq_safe() for the
   timers with the related quirks caused by pm_runtime_irq_safe(),
   and have the standard assigned-clocks and assigned-clock-parents
   deal with setting the source clock
 
 - Fix potentially uninitialized value for display init code if
   regmap_read() fails
