Subject: [PATCH v2 0/2] UBSan: run-time undefined behavior sanity checker
Date: Fri, 14 Nov 2014 15:50:44 +0300
Message-id: <1415969446-26356-1-git-send-email-a.ryabinin@samsung.com>
Sender: linux-kernel-owner@vger.kernel.org

Next spin of UBSan and there are two patches from now.
"Two there should be; no more, no less. One to embody the UBSan,
the other to not deadlock it."

Patches on top of v3.18-rc4. As usual they are available in git:
	git://github.com/aryabinin/linux ubsan/v2

Changes since v1:
   - Refactoring and cleanups in lib/ubsan.c including Sasha's complains.
   - Some spelling fixes from Randy
   - Fixed possible memory corruption on 64 big endian machines, spotted by Rasmus.
   - Links to the relevant GCC documentation added into changelog (Peter).
   - Added documentation.
   - Fix deadlock caused by kernel/printk/printk.c instrumentation
        (patch "kernel: printk: specify alignment for struct printk_log").
   - Dropped useless 'Indirect call of a function through a function pointer of the wrong type'
     checker. GCC doesn't support this, and as clang manual says it's for C++ only.
   - Added checker for __builtin_unreachable() calls.
   - Removed redundant -fno-sanitize=float-cast-overflow from CFLAGS.
   - Added lock to prevent mixing reports.
