------------------------------------------------------
From: Liam Howlett <liam.howlett@xxxxxxxxxx>
Subject: kernel/events/uprobes: use vma_lookup() in find_active_uprobe()
Use vma_lookup() to find the VMA at a specific address. As vma_lookup()
will return NULL if the address is not within any VMA, the start address
no longer needs to be validated.
