Note that the following newly exported headers have userspace compilation
errors:

/usr/include/drm/armada_drm.h:26:2: error: unknown type name 'uint32_t'
  uint32_t handle;

/usr/include/linux/btrfs_tree.h:390:12: error: 'BTRFS_UUID_SIZE' undeclared here (not in a function)
  __u8 uuid[BTRFS_UUID_SIZE];

/usr/include/linux/cryptouser.h:58:16: error: 'CRYPTO_MAX_ALG_NAME' undeclared here (not in a function)
  char cru_name[CRYPTO_MAX_ALG_NAME];

/usr/include/linux/kfd_ioctl.h:33:2: error: unknown type name 'uint32_t'
  uint32_t major_version; /* from KFD */

/usr/include/linux/smc_diag.h:6:27: fatal error: rdma/ib_verbs.h: No such file or directory
 #include <rdma/ib_verbs.h>

/usr/include/linux/wil6210_uapi.h:73:2: error: unknown type name 'uint32_t'
  uint32_t op; /* enum wil_memio_op */

I think they should be fixed first.
