Merge tag 'modules-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux

Pull modules updates from Luis Chamberlain:
"Finally something fun. Mike Rapoport does some cleanup to allow us to
take out module_alloc() out of modules into a new paint shedded
execmem_alloc() and execmem_free() so to make emphasis these helpers
are actually used outside of modules.

It starts with a non-functional changes API rename / placeholders to
then allow architectures to define their requirements into a new shiny
struct execmem_info with ranges, and requirements for those ranges.

Archs now can intitialize this execmem_info as the last part of
mm_core_init() if they have to diverge from the norm. Each range is a
known type clearly articulated and spelled out in enum execmem_type.

Although a lot of this is major cleanup and prep work for future
enhancements an immediate clear gain is we get to enable KPROBES
without MODULES now. That is ultimately what motiviated to pick this
work up again, now with smaller goal as concrete stepping stone"

Pull non-MM updates from Andrew Morton:
"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'"

arch: turn off -Werror for architectures with known warnings

A couple of architectures enable -Werror for their own files regardless of
CONFIG_WERROR but also have known warnings that fail the build with
-Wmissing-prototypes enabled by default:

arch/alpha/lib/memcpy.c:153:8: error: no previous prototype for 'memcpy' [-Werror=missing-prototypes]
arch/alpha/kernel/irq.c:96:1: error: no previous prototype for 'handle_irq' [-Werror=missing-prototypes]
arch/mips/kernel/signal.c:673:17: error: no previous prototype for ‘sys_rt_sigreturn’ [-Werror=missing-prototypes]

arch/mips/mm/fault.c:323:17: error: no previous prototype for ‘do_page_fault’ [-Werror=missing-prototypes]
arch/sparc/vdso/vma.c:246:12: warning: no previous prototype for ‘init_vdso_image’ [-Wmissing-prototypes]v
arch/sparc/vdso/vdso32/../vclock_gettime.c:343:1: warning: no previous prototype for ‘__vdso_gettimeofday_stick’ [-Wmissing-prototypes]

arch/sparc/prom/misc_64.c:165:5: warning: no previous prototype for ‘prom_get_mmu_ihandle’ [-Wmissing-prototypes]

This appears to be an artifact from the times when this architecture code
was better maintained that most device drivers and before CONFIG_WERROR
was added. Now it just gets in the way, so remove all of these.

Powerpc and x86 both still have their own Kconfig options to enable
-Werror for some of their files. These architectures are better
maintained than most and the options are easy to disable, so leave those
untouched.
