Core features:
- Add workaround for C1-Pro erratum 4193714 - early CME (SME unit)
DVMSync acknowledgement. The fix consists of sending IPIs on TLB
maintenance to those CPUs running in user space with SME enabled
- Include kernel-hwcap.h in list of generated files (missed in a recent
commit generating the KERNEL_HWCAP_* macros)
CCA:
- Fix RSI_INCOMPLETE error check in arm-cca-guest
MPAM:
- Fix an unmount->remount problem with the CDP emulation, uninitialised
variable and checker warnings

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull more arm64 updates from Catalin Marinas:
"The main 'feature' is a workaround for C1-Pro erratum 4193714
requiring IPIs during TLB maintenance if a process is running in user
space with SME enabled.
The hardware acknowledges the DVMSync messages before completing
in-flight SME accesses, with security implications. The workaround
makes use of the mm_cpumask() to track the cores that need
interrupting (arm64 hasn't used this mask before).
The rest are fixes for MPAM, CCA and generated header that turned up
during the merging window or shortly before.
