Commit aca43fe839 ("btrfs: remove unused raid56 functions which were
dedicated for scrub") removed the special handling of RAID56 scrub for
missing device.
As scrub goes full mirror_num based recovery, that means if it hits a
missing device in RAID56, it would just try the next mirror, which would
go through the BTRFS_RBIO_READ_REBUILD operation.
This means there is no longer any use of BTRFS_RBIO_REBUILD_MISSING
operation and we can safely remove it.

The function btrfs_map_block() is a critical part of the btrfs storage
layer, which handles mapping of logical ranges to physical ranges.
Thus it's better to have some basic explanation, especially on the
following points:
- Segment split by various boundaries
As a continuous logical range may be split into different segments,
due to various factors like zones and RAID0/5/6/10 boundaries.
- The meaning of @mirror_num
- The possible single stripe optimization
- One deprecated parameter @need_raid_map
Just explicitly mark it deprecated so we're aware of the problem.

pinctrl_gpio_request() is essential in the code flow because it changes the

Previously only `ident` and generic types were supported in the
`{try_}{pin_}init!` macros. This patch allows arbitrary path fragments,
so for example `Foo::Bar` but also very complex paths such as
`<Foo as Baz>::Bar::<0, i32>`.
Internally this is accomplished by using `path` fragments. Due to some
peculiar declarative macro limitations, we have to "forget" certain
additional parsing information in the token trees. This is achieved by
using the `paste!` proc macro. It does not actually modify the input,
since no `[< >]` will be present in the input, so it just strips the
information held by declarative macros. For example, if a declarative
macro takes `$t:path` as its input, it cannot sensibly propagate this to
a macro that takes `$($p:tt)*` as its input, since the `$t` token will
only be considered one `tt` token for the second macro. If we first pipe
the tokens through `paste!`, then it parses as expected.

```
struct Foo {
a: usize,
b: usize,
}
let a = 10;
let foo = init!(Foo{
a: a + 1, // This creates a local variable named `a`.
b: a, // This refers to that variable!
});
let foo = Box::init!(foo)?;
assert_eq!(foo.a, 11);
assert_eq!(foo.b, 11);
```
This patch changes this behavior, so the above code would panic at the
last assertion, since `b` would have value 10.

Since the next patch has a stack variable to store the struct, the

builds no stack overflow error is caused. In release builds this was not
a problem since the code was optimized away due to the `if false`.

Remove 10us delay in cdns_spi_process_fifo() (called from cdns_spi_irq())
to fix data corruption issue on Master side when this driver
configured in Slave mode, as Slave is failed to prepare the date
on time due to above delay.
Add 10us delay before processing the RX FIFO as TX empty doesn't
guarantee valid data in RX FIFO.

Commit 6f486556ab ("spi: stm32: renaming of spi_master into
spi_controller") included an accidential reverted of a change added in
commit 1e49291125 ("spi: stm32: split large transfers based on word
size instead of bytes").
This breaks large SPI transfers with word sizes > 8 bits, which are
e.g. common when driving MIPI DBI displays.
Fix this by using `spi_split_transfers_maxwords()` instead of
`spi_split_transfers_maxsize()`.

There is a global definition of memcmp() that gets built on m68k but is
never used and causes a warning because of the missing prototype:

The generic __div64_32() definition is built on all architectures that
don't provide this as a macro. m68k however neither defines nor
