Hello Linus, please pull s390 changes for 6.4-rc3. It contain a fix to statfs code, which was acked by Andrew Morton: https://lore.kernel.org/all/20230511204513.3d0d60f0315350177a800284@xxxxxxxxxxxxxxxxxxxx/ Thank you, Alexander The following changes since commit f1fcbaa18b28dec10281551dfe6ed3a3ed80e3d6: Linux 6.4-rc2 (2023-05-14 12:51:40 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git tags/s390-6.4-2 for you to fetch changes up to 0f1cbf941d5949110adf70725a9614e622de8d99: s390/iommu: get rid of S390_CCW_IOMMU and S390_AP_IOMMU (2023-05-01 14:11:28 -0300) ---------------------------------------------------------------- s390 updates for 6.4-rc3 - 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. ---------------------------------------------------------------- Alexander Gordeev (2): s390/topology: honour nr_cpu_ids when adding CPUs s390/ipl: fix IPIB virtual vs physical address confusion Heiko Carstens (3): s390/crypto: use vector instructions only if available for ChaCha20 s390/defconfigs: set CONFIG_INIT_STACK_NONE=y s390/qdio: fix do_sqbs() inline assembly constraint Holger Dengler (1): s390/pkey: zeroize key blobs Ilya Leoshkevich (2): statfs: enforce statfs[64] structure initialization s390/uapi: cover statfs padding by growing f_spare Jason Gunthorpe (1): s390/iommu: get rid of S390_CCW_IOMMU and S390_AP_IOMMU Lukas Bulwahn (1): s390/Kconfig: remove obsolete configs SCHED_{BOOK,DRAWER} Vineeth Vijayan (1): s390/cio: include subchannels without devices also for evaluation Documentation/s390/vfio-ap.rst | 1 - arch/s390/Kconfig | 11 +--------- arch/s390/configs/debug_defconfig | 3 +-- arch/s390/configs/defconfig | 3 +-- arch/s390/configs/zfcpdump_defconfig | 1 + arch/s390/crypto/chacha-glue.c | 2 +- arch/s390/include/asm/compat.h | 2 +- arch/s390/include/uapi/asm/statfs.h | 4 ++-- arch/s390/kernel/ipl.c | 3 +-- arch/s390/kernel/topology.c | 32 +++++++++++++++------------- drivers/iommu/Kconfig | 16 -------------- drivers/s390/cio/device.c | 2 ++ drivers/s390/cio/qdio.h | 2 +- drivers/s390/crypto/pkey_api.c | 3 +++ fs/statfs.c | 4 ++-- 15 files changed, 34 insertions(+), 55 deletions(-)
