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. 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
