Subject: [PATCH v7 06/18] kexec: include asm/early_ioremap.h

From: Arnd Bergmann <arnd@...db.de>

The early_memremap() function is decleared 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);
      |               ^
