If not I wonder if there's another way to do this without so much code churn. Maybe like adding this extra parameter only to load_elf_ram_sym() and calling that directly from the one caller that needs it? That would leave the prototypes of all existing load_elf_* wrappers (and all its current callers) undisturbed. Or maybe adding a new wrapper like load_elf_notes() with the extra parameter if calling load_elf_ram_sym directly is not desired instead of changing load_elf and all its callers? If others think it's not a problem to change so many files for this, then I don't mind but load_elf already seems to have too many usually NULL parameters so not adding one more which needs changing so many files seems like a good idea to me and it seems previously adding wrappers for this was the preferred way..

This patch adds an optional function pointer, 'elf_note_fn', to load_elf() which causes load_elf() to additionally parse any ELF program headers of type PT_NOTE and check to see if the ELF Note is of the type specified by the 'translate_opaque' arg. If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.
