| Date: Wed, 23 Apr 2025 18:29:18 +0200 |
| |
| early_memremap() is declared in a header that is only indirectly included |
| here: |
| |
| kernel/kexec_handover.c:1116:8: error: call to undeclared function 'early_memremap'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] |
| 1116 | fdt = early_memremap(fdt_phys, fdt_len); |
