Subject: [git pull] m68knommu changes for v5.19

Hi Linus,

Please pull the m68knommu changes for v5.19.

There is a collection of changes to add elf-fdpic loader support for m68k.
Also a collection of various fixes. They include typo corrections, undefined
symbol compilation fixes, removal of the ISA_DMA_API support and removal of
unused code.

I expect you will get a merge conflict in arch/m68k/kernel/ptrace.c.
The change to add some regset support conflicts with recent changes to
syscall_trace_enter/leave. The changes themselves don't interfere with
each other, just the diff context. Remove the conflicting line
"#endif /* CONFIG_COLDFIRE */" to resolve.

Regards
Greg
