Merge tag 's390-6.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

 - Add firmware sysfs interface which allows user space to retrieve the
   dump area size of the machine

 - Add 'measurement_chars_full' CHPID sysfs attribute to make the
   complete associated Channel-Measurements Characteristics Block
   available

 - Add virtio-mem support

 - Move gmap aka KVM page fault handling from the main fault handler to
   KVM code. This is the first step to make s390 KVM page fault handling
   similar to other architectures. With this first step the main fault
   handler does not have any special handling anymore, and therefore
   convert it to support LOCK_MM_AND_FIND_VMA

 - With gcc 14 s390 support for flag output operand support for inline
   assemblies was added. This allows for several optimizations:

     - Provide a cmpxchg inline assembly which makes use of this, and
       provide all variants of arch_try_cmpxchg() so that the compiler
       can generate slightly better code

     - Convert a few cmpxchg() loops to try_cmpxchg() loops

     - Similar to x86 add a CC_OUT() helper macro (and other macros),
       and convert all inline assemblies to make use of them, so that
       depending on compiler version better code can be generated

 - List installed host-key hashes in sysfs if the machine supports the
   Query Ultravisor Keys UVC

 - Add 'Retrieve Secret' ioctl which allows user space in protected
   execution guests to retrieve previously stored secrets from the
   Ultravisor

 - Add pkey-uv module which supports the conversion of Ultravisor
   retrievable secrets to protected keys

 - Extend the existing paes cipher to exploit the full AES-XTS hardware
   acceleration introduced with message-security assist extension 10

 - Convert hopefully all sysfs show functions to use sysfs_emit() so
   that the constant flow of such patches stop

 - For PCI devices make use of the newly added Topology ID attribute to
   enable whole card multi-function support despite the change to PCHID
   per port. Additionally improve the overall robustness and usability
   of the multifunction support

 - Various other small improvements, fixes, and cleanups
