- Add check whether the required facilities are installed
before using the s390-specific ChaCha20 implementation.
- Key blobs for s390 protected key interface IOCTLs commands
PKEY_VERIFYKEY2 and PKEY_VERIFYKEY3 may contain clear key
material. Zeroize copies of these keys in kernel memory
after creating protected keys.
- Set CONFIG_INIT_STACK_NONE=y in defconfigs to avoid extra
overhead of initializing all stack variables by default.
- Make sure that when a new channel-path is enabled all
subchannels are evaluated: with and without any devices
connected on it.
- When SMT thread CPUs are added to CPU topology masks the
nr_cpu_ids limit is not checked and could be exceeded.
Respect the nr_cpu_ids limit and avoid a warning when
CONFIG_DEBUG_PER_CPU_MAPS is set.
- The pointer to IPL Parameter Information Block is stored
in the absolute lowcore as a virtual address. Save it as
the physical address for later use by dump tools.
- Fix a Queued Direct I/O (QDIO) problem on z/VM guests using
QIOASSIST with dedicated (pass through) QDIO-based devices
such as FCP, real OSA or HiperSockets.
- s390's struct statfs and struct statfs64 contain padding,
which field-by-field copying does not set. Initialize the
respective structures with zeros before filling them and
copying to userspace.
- Grow s390 compat_statfs64, statfs and statfs64 structures
f_spare array member to cover padding and simplify things.
- Remove obsolete SCHED_BOOK and SCHED_DRAWER configs.
- Remove unneeded S390_CCW_IOMMU and S390_AP_IOM configs.
