Set free_heap_pages()'s need_scrub to true if alloc_domheap_pages() returns pages back to heap as result of assign_pages() error when those pages were requested with MEMF_no_scrub flag. We need to do this because there is a possibility that alloc_heap_pages() might clear buddy's PGC_need_scrubs

Make it possible for the user to specify, with the boot time parameter rcu_idle_timer_period_ms, how frequently a CPU that went idle with pending RCU callbacks should be woken up to check if the grace period ended. Typical values (i.e., some of the values used by Linux as the tick frequency) are

[Xen-devel] [PATCH 3/3] xen: RCU: make the period of the idle timer adaptive.

Basically, if the RCU idle timer, when (if!) it fires, finds that the grace period isn't over, we increase the timer's period (i.e., it will fire later, next time). If, OTOH, it finds the grace period is already finished, we decrease the timer's period (i.e., it will fire a bit earlier next time).

[Xen-devel] [PATCH 2/3] python: Extract registered watch search logic from xspy_read_watch()

When a watch fires, xspy_read_watch() checks whether the client has registered interest in the path which changed and, if so, returns the path and a client-supplied token. The binding for xs_check_watch() needs to do the same, so this patch extracts the search code into a separate function.
