[PATCH v3] mm/page_owner: ignore everything below the IRQ entry point

2018-03-27 Thread Maninder Singh
Check whether the allocation happens in an IRQ handler. This lets us strip everything below the IRQ entry point to reduce the number of unique stack traces needed to be stored. so moved code of KASAN in generic file so that page_owner can also do same filteration. Initial KASAN commit id=be7635e7
