So this commit started generating the following new build warning on x86 32-bit
allyesconfig and allmodconfig builds:
drivers/firmware/efi/fake_mem.c:186:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
Which comes from:
u64 new_memmap_phy;
...
memmap.phys_map = (void *)new_memmap_phy;
While efi_memory_map has a 32-bit pointer:
struct efi_memory_map {
void *phys_map;
void *map;
void *map_end;
int nr_map;
unsigned long desc_version;
unsigned long desc_size;
};
Thanks,
Ingo
