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.
