Merge tag 's390-6.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Vasily Gorbik:
- 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
