[PATCH v3 0/3] s390/crash: support multi-segment iterators

[Alexander Gordeev <agordeev@linux.ibm.com>]

Hi Matthew et al,

This series completes 5d8de293c224 ("vmcore: convert copy_oldmem_page() to
take an iov_iter") for s390.

@Matthew,
  Please, let me know if you are not okay with Suggested-by tag in patch 3.

Changes since v2:
  - Matthew Wilcox suggestion is adopted, with that...
  - copy_to_iter() is used instead of custom implementation;

Changes since v1:
  - number of bytes left to copy on fail fixed;

Thanks!

  s390/crash: move copy_to_user_real() to crash_dump.c
  s390/crash: use static swap buffer for copy_to_user_real()
