If the purgatory object contains multiple\nexecutable sections with overlapping sh_addr, the entrypoint check can\nmatch more than once and trigger a WARN.\n\nDerive the entry section from the purgatory_start symbol when present and\ncompute image->start from its final placement.  Keep the existing e_entry\nfallback for purgatories that do not expose the symbol.\n\nWARNING: kernel/kexec_file.c:1009 at kexec_load_purgatory+0x395/0x3c0, CPU#10: kexec/1784\nCall Trace:\n <TASK>\n bzImage64_load+0x133/0xa00\n __do_sys_kexec_file_load+0x2b3/0x5c0\n do_syscall_64+0x81/0x610\n entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\n[me@linux.beauty: move helper to avoid forward declaration, per Baoquan]",
