Linus, please merge this cycle's batch of non-MM patches, thanks.

There is one known forthcoming build issue which is not accompanied by
a merge issue. This, and its linux-next resolution is:

next-next tree, drivers/net/phy/aquantia/aquantia_firmware.c:
https://lkml.kernel.org/r/20231221130946.7ed9a805@xxxxxxxxxxxxxxxx

Forthcoming merge issues and their linux-next resolutions are:

asm-generic tree, arch/mips/include/asm/traps.h

The following changes since commit 4376807bf2d5371c3e00080c972be568c3f8a7d1:

crash_core: fix and simplify the logic of crash_exclude_mem_range() (2024-01-05 10:45:25 -0800)

----------------------------------------------------------------
Quite a lot of kexec work this time around. Many singleton patches in
many places. The notable patch series are:

- nilfs2 folio conversion from Matthew Wilcox in "nilfs2: Folio
conversions for file paths".

- Additional nilfs2 folio conversion from Ryusuke Konishi in "nilfs2:
Folio conversions for directory paths".

- IA64 remnant removal in Heiko Carstens's "Remove unused code after
IA-64 removal".

- Arnd Bergmann has enabled the -Wmissing-prototypes warning everywhere
in "Treewide: enable -Wmissing-prototypes". This had some followup
fixes:

- Nathan Chancellor has cleaned up the hexagon build in the series
"hexagon: Fix up instances of -Wmissing-prototypes".

- Nathan also addressed some s390 warnings in "s390: A couple of
fixes for -Wmissing-prototypes".

- Arnd Bergmann addresses the same warnings for MIPS in his series
"mips: address -Wmissing-prototypes warnings".

- Baoquan He has made kexec_file operate in a top-down-fitting manner
similar to kexec_load in the series "kexec_file: Load kernel at top of
system RAM if required"

- Baoquan He has also added the self-explanatory "kexec_file: print out
debugging message if required".

- Some checkstack maintenance work from Tiezhu Yang in the series
"Modify some code about checkstack".

- Douglas Anderson has disentangled the watchdog code's logging when
multiple reports are occurring simultaneously. The series is "watchdog:
Better handling of concurrent lockups".

- Yuntao Wang has contributed some maintenance work on the crash code in
"crash: Some cleanups and fixes".
