[PATCH 1/2] sched, numa, mm: Count WS scanning against present PTEs, not virtual memory ranges

From: Peter Zijlstra By accounting against the present PTEs, scanning speed reflects the actual present (mapped) memory. For this we modify mm/mprotect.c::change_protection() to return the number of ptes modified. (No change in functionality.) Suggested-by: Ingo Molnar Signed-off-by: Peter Zij

[PATCH V2 1/1] Drivers: hv: Add Hyper-V balloon driver

Add the basic balloon driver. Windows hosts dynamically manage the guest memory allocation via a combination memory hot add and ballooning. Memory hot add is used to grow the guest memory upto the maximum memory that can be allocatted to the guest. Ballooning is used to both shrink as well as expan

[PATCH RESEND V2 0/1] Drivers: hv

Add a basic balloon driver to take advantage of the dynamic memory management functionality supported on Windows hosts. Windows requires the guests to support both memory hot add as well as ballooning. In this patch we are adding the basic balloon driver. Memory hot add will be added in a subsequen
