  gendwarfksyms: Fix structure type overrides
  kbuild: move warnings about linux/export.h from W=1 to W=2

As we always iterate through the entire die_map when expanding
type strings, recursively processing referenced types in
type_expand_child() is not actually necessary. Furthermore,
the type_string kABI rule added in commit c9083467f7b9
("gendwarfksyms: Add a kABI rule to override type strings") can
fail to override type strings for structures due to a missing
kabi_get_type_string() check in this function.

Fix the issue by dropping the unnecessary recursion and moving
the override check to type_expand(). Note that symbol versions
are otherwise unchanged with this patch.

This hides excessive warnings, as nobody builds with W=2.

Pull io_uring fixes from Jens Axboe:

 - Fix for a race between SQPOLL exit and fdinfo reading.

   It's slim and I was only able to reproduce this with an artificial
   delay in the kernel. Followup sparse fix as well to unify the access
   to ->thread.

 - Fix for multiple buffer peeking, avoiding truncation if possible.

 - Run local task_work for IOPOLL reaping when the ring is exiting.

   This currently isn't done due to an assumption that polled IO will
   never need task_work, but a fix on the block side is going to change
   that.
