No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Log records may store either data or pointers to more records. In both
cases they must have the same size. With 64-bit pointers, the amount
of data that can occupy the same space as a pointer has to be adjusted.
And storage alignment has to accommodate actual pointers not u32_t.

Log arguments were hardcoded to u32_t values. On 64-bit systems, this
is rather restrictive. To make things clear, arguments now have their
own type, log_arg_t, which now can be adjusted in only one location
if need be. It is currently defined as unsigned long whose effective
width is equivalent to u32_t on 32-bit systems, and u64_t on 64-bit
systems.

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c
include/linker/kobject-text.ld
kernel/include/syscall_handler.h
scripts/gen_kobject_list.py

Extended supported number of arguments in log message. Support for
messages consisting of more than 2 chunks had to be added. So far
messages could consist of one chunk (up to 3 args) or two chunks
(2 args in first chunk and 7 in second chunk). Once 2+ chunks
support is added number of arguments is techinically limited to
15 (4 bit field). log_core and log_output extended to suppor 10

When log API is used it should give the same side effect when enabled

When log is locally disabled then structures associated with the module
are not created. Logger API macros were evaluating those structues even
when log was disabled for given module. That resulted in compilation
error. Macros has been improved to not touch those structures when
log is disabled for given module.
