  s390: Add build salt to the vDSO (2026-07-08 17:02:48 +0200)

----------------------------------------------------------------
s390 updates for 7.2-rc3

- Fix missing array_index_nospec() call in diag310 memory topology code
  to prevent speculative execution with a user controlled array index

- Fix get_align_mask() return type to match vm_unmapped_area_info
  align_mask, avoiding possible truncation for future larger masks

- Remove empty zcrypt CEX2 files left over after CEX2 and CEX3 driver
  removal

- Add build salt to the vDSO so it gets a unique build id, similar to
  the kernel and modules
