  s390/vfio-ap: Fix no AP queue sharing allowed message written to kernel log (2025-04-01 16:24:22 +0200)

----------------------------------------------------------------
more s390 updates for 6.15 merge window

- Fix machine check handler _CIF_MCCK_GUEST bit setting by adding the
  missing base register for relocated lowcore address

- Fix build failure on older linkers by conditionally adding the -no-pie
  linker option only when it is supported

- Fix inaccurate kernel messages in vfio-ap by providing descriptive
  error notifications for AP queue sharing violations

- Fix PCI isolation logic by ensuring non-VF devices correctly return
  false in zpci_bus_is_isolated_vf()

- Fix PCI DMA range map setup by using dma_direct_set_offset() to add a
  proper sentinel element, preventing potential overruns and translation
  errors

- Cleanup header dependency problems with asm-offsets.c

- Add fault info for unexpected low-address protection faults in user mode

- Add support for HOTPLUG_SMT, replacing the arch-specific "nosmt"
  handling with common code handling

- Use bitop functions to implement CPU flag helper functions to ensure
  that bits cannot get lost if modified in different contexts on a CPU

- Remove unused machine_flags for the lowcore
