[PATCH] android: binder: Disable preemption while holding the global binder lock

In Android systems, the display pipeline relies on low latency binder transactions and is therefore sensitive to delays caused by contention for the global binder lock. Jank is siginificantly reduced by disabling preemption while the global binder lock is held. Originally-from: Riley Andrews

[PATCH 2/3] Drivers: hv: utils: Use TimeSync samples to adjust the clock after boot.

From: Alex Ng Only the first 50 samples after boot were being used to discipline the clock. After the first 50 samples, any samples from the host were ignored and the guest clock would eventually drift from the host clock. This patch allows TimeSync-enabled guests

[PATCH 1/3] Drivers: hv: utils: Rename version definitions to reflect protocol version.

From: Alex Ng Different Windows host versions may reuse the same protocol version when negotiating the TimeSync, Shutdown, and Heartbeat protocols. We should only refer to the protocol version to avoid conflating the two concepts. Signed-off-by: Alex Ng

[PATCH 3/3] Drivers: hv: utils: Support TimeSync version 4.0 protocol samples.

From: Alex Ng This enables support for more accurate TimeSync v4 samples when hosted under Windows Server 2016 and newer hosts. The new time samples include a "vmreferencetime" field that represents the guest's TSC value when the host generated its time sample.
