I have full of build warnings / errors in x86 and iommu

X86:

arch/x86/include/asm/string_64.h:14:14: warning: conflicting types for built-in function ‘memcpy’; expected ‘void *(void *, const void *, long unsigned int)’ [-Wbuiltin-declaration-mismatch]
   14 | extern void *memcpy(void *to, const void *from, size_t len);
      |              ^~~~~~
arch/x86/include/asm/string_64.h:7:1: note: ‘memcpy’ is declared in header ‘<string.h>’
    6 | #include <linux/jump_label.h>
  +++ |+#include <string.h>

And so on for standard string function definitions.

IOMMU:

drivers/iommu/amd/io_pgtable.c: In function ‘v1_alloc_pgtable’:
drivers/iommu/amd/io_pgtable.c:551:32: error: assignment to ‘size_t (*)(struct io_pgtable_ops *, long unsigned int,  size_t,  struct iommu_iotlb_gather *)’ {aka ‘unsigned int (*)(struct io_pgtable_ops *, long unsigned int,  unsigned int,  struct iommu_iotlb_gather *)’} from incompatible pointer type ‘long unsigned int (*)(struct io_pgtable_ops *, long unsigned int,  size_t,  struct iommu_iotlb_gather *)’ {aka ‘long unsigned int (*)(struct io_pgtable_ops *, long unsigned int,  unsigned int,  struct iommu_iotlb_gather *)’} [-Werror=incompatible-pointer-types]
  551 |  pgtable->iop.ops.unmap        = iommu_v1_unmap_page;
      |                                ^
cc1: some warnings being treated as errors

Is it only me?
