asm-generic fixes for 6.10

These are some bugfixes for system call ABI issues I found while
 working on a cleanup series. None of these are urgent since these
 bugs have gone unnoticed for many years, but I think we probably
 want to backport them all to stable kernels, so it makes sense
 to have the fixes included as early as possible.
 
 One more fix addresses a compile-time warning in kallsyms that was
 uncovered by a patch I did to enable additional warnings in 6.10. I had
 mistakenly thought that this fix was already merged through the module
 tree, but as Geert pointed out it was still missing.
