  s390/debug: Fix typo in debug_sprintf_format_fn() comment (2025-08-06 17:18:27 +0200)

----------------------------------------------------------------
more s390 updates for 6.17 merge window

- Support MMIO read/write tracing

- Enable THP swapping and THP migration

- Unmask SLCF bit ("stateless command filtering") introduced with
  CEX8 cards, so that user space applications like lszcrypt could
  evaluate and list this feature

- Fix the value of high_memory variable, so it considers possible
  tailing offline memory blocks

- Make vmem_pte_alloc() consistent and always allocate memory of
  PAGE_SIZE for page tables. This ensures a page table occupies
  the whole page, as the rest of the code assumes

- Fix kernel image end address in the decompressor debug output

- Fix a typo in debug_sprintf_format_fn() comment
