Subject: [PATCH 0/4] kasan: add clang support

This patch series adds support for building KASAN-enabled kernels with clang.
This mostly involves adding callbacks for a couple of new features in LLVM's
AddressSanitizer implementation.  We also need to probe for the (slightly
different) CFLAGS used to configure ASAN with clang.

*** BLURB HERE ***

Alexander Potapenko (1):
  kasan: added functions for unpoisoning stack variables

Greg Hackmann (3):
  kasan: support alloca() poisoning
  kasan: support LLVM-style asan parameters
  kasan: add compiler support for clang
