- Fix the style of protected key API driver source: use x-mas tree for all local variable declarations. - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore. Both structures have a fixed size buffer, but with the support of ECC protected key these buffers are not big enough. Use dynamic buffers internally and transparently for userspace. - Add support for a new 'non CCA clear key token' with ECC clear keys supported: ECC P256, ECC P384, ECC P521, ECC ED25519 and ECC ED448. This makes it possible to derive a protected key from the ECC clear key input via PKEY_KBLOB2PROTK3 ioctl, while currently the only way to derive is via PCKMO instruction. - The s390 PMU of PAI crypto and extension 1 NNPA counters use atomic_t for reference counting. Replace this with the proper data type refcount_t. - Select ARCH_SUPPORTS_INT128, but limit this to clang for now, since gcc generates inefficient code, which may lead to stack overflows. - Replace one-element array with flexible-array member in struct vfio_ccw_parent and refactor the rest of the code accordingly. Also, prefer struct_size() over sizeof() open- coded versions. - Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether the system memory should be cleared or not once dumped. - Fix a hang when a user attempts to remove a VFIO-AP mediated device attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver callback to request a release of the device. - Fix calculation for R_390_GOTENT relocations for modules. - Allow any user space process with CAP_PERFMON capability read and display the CPU Measurement facility counter sets. - Rework large statically-defined per-CPU cpu_cf_events data structure and replace it with dynamically allocated structures created when a perf_event_open() system call is invoked or /dev/hwctr device is accessed. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZJsnCRccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8D+RAQCN5CYdql/X8kOMcs4jJvDHEZf8 5CHYfmT2SLNs+zWtLgD/f/C9XXv3El/0wMBvuWSZ+T1nw+imt2cz+FJ+Nor+UQg= =R7Dm -----END PGP SIGNATURE----- Merge tag 's390-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Fix the style of protected key API driver source: use x-mas tree for all local variable declarations - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore.
