s390/cio/ioasm: Convert to use flag output macros (2024-11-13 14:31:34 +0100)
----------------------------------------------------------------
s390 updates for 6.13 merge window
- 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
