Lokesh Gidra a905086c85 ANDROID: userfaultfd: allow SPF for UFFD_FEATURE_SIGBUS on private+anon 
Currently we bail out of speculative page fault when we detect that the
fault address is in a userfaultfd registered vma. However, if userfaultfd
is being used with UFFD_FEATURE_SIGBUS feature, then handle_userfault()
doesn't do much and is easiest to handle with SPF. This patch lets
MISSING userfaultfs on private anonymous mappings be allowed with SPF if
UFFD_FEATURE_SIGBUS is used.

With this patch we get >99% success rate for userfaults caused during
userfaultfd GC's compaction phase. This translates into eliminating
uninterruptible sleep time in do_page_fault() due to userfaults.
