[PATCH+RFC+HACK 00/16] xen: arm initial support for xgene arm64 platform
I''m afraid this series is rather a grab bag and it is distressingly
large at this stage. With this series I can boot an Xgene board until it
fails to find its SATA controller. This is a dom0 issue for which
patches are pending from APM (/me nudges Anup).
As well as the APM specific platform stuff there are also some generic
improvements which were either necessary or useful during this

[PATCH 0/5] KVM: arm64: vcpu preempted check support
From: Zengruan Ye <yezengruan at huawei.com>
This patch set aims to support the vcpu_is_preempted() functionality
under KVM/arm64, which allowing the guest to obtain the vcpu is
currently running or not. This will enhance lock performance on
overcommitted hosts (more runnable vcpus than physical cpus in the
system) as doing busy waits for preempted vcpus will hurt system
performance far

This patch set aims to support the vcpu_is_preempted() functionality

currently running or not. This will enhance lock performance on
overcommitted hosts (more runnable VCPUs than physical CPUs in the

performance far worse than early yielding.
