tap: Refactoring macvtap.c
macvtap module has code for tap/queue management and link management. This patch splits the code into macvtap_main.c for link management and tap.c for tap/queue management. Functionality in tap.c can be re-used for implementing tap on other virtual interfaces. Signed-off-by: Sainath Grandhi <sainath.grandhi@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

e/exynos_mct: Clear interrupt when cpu is shut down
When a CPU goes offline a potentially pending timer interrupt is not cleared. When the CPU comes online again then the pending interrupt is delivered before the per cpu clockevent device is initialized. As a consequence the tick interrupt handler dereferences a NULL pointer. [ 51.251378] Unable to handle kernel NULL pointer dereference at virtual address 00000040 [ 51.289348] task: ee942d00 task.stack: ee960000 [ 51.293861] PC is at tick_periodic+0x38/0xb0 [ 51.298102] LR is at tick_handle_periodic+0x1c/0x90 Clear the pending interrupt in the cpu dying path.
