Pull locking fixes from Ingo Molnar: "Misc fixes: - Fix a S390 boot hang that was caused by the lock-break logic. Remove lock-break to begin with, as review suggested it was unreasonably fragile and our confidence in its continued good health is lower than our confidence in its removal. - Remove the lockdep cross-release checking code for now, because of unresolved false positive warnings. This should make lockdep work well everywhere again. - Get rid of the final (and single) ACCESS_ONCE() straggler and remove the API from v4.15. - Fix a liblockdep build warning" * 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: tools/lib/lockdep: Add missing declaration of 'pr_cont()' checkpatch: Remove ACCESS_ONCE() warning compiler.h: Remove ACCESS_ONCE() tools/include: Remove ACCESS_ONCE() tools/perf: Convert ACCESS_ONCE() to READ_ONCE() locking/lockdep: Remove the cross-release locking checks locking/core: Remove break_lock field when CONFIG_GENERIC_LOCKBREAK=y locking/core: Fix deadlock during boot on systems with GENERIC_LOCKBREAK

tools/headers: Synchronize kernel <-> tooling headers

2017-12-15T12:49:28Z

Two kernel headers got modified recently, which are used by tooling as well: tools/include/uapi/linux/kvm.h arch/x86/include/asm/cpufeatures.h None of those changes have an effect on tooling, so do a plain copy.

tools/lib/lockdep: Add missing declaration of 'pr_cont()'

2017-12-13T10:17:35Z

Commit: 681fbec881de ("lockdep: Use consistent printing primitives") has moved lockdep away from using printk() for printing. The commit added usage of pr_cont() which wasn't wrapped in the userspace headers, causing the following warning for the liblockdep build: ../../../kernel/locking/lockdep.c:3544:2: warning: implicit declaration of function 'pr_cont' [-Wimplicit-function-declaration] Adding an empty declaration of 'pr_cont' fixes the problem.

bpf: fix broken BPF selftest build

2017-12-12T17:51:12Z

At least on x86_64, the kernel's BPF selftests seemed to have stopped to build due to 618e165b2a8e ("selftests/bpf: sync kernel headers and introduce arch support in Makefile"): [...] In file included from test_verifier.c:29:0: ../../../include/uapi/linux/bpf_perf_event.h:11:32: fatal error: asm/bpf_perf_event.h: No such file or directory #include ^ compilation terminated. [...] While pulling in tools/arch/*/include/uapi/asm/bpf_perf_event.h seems to work fine, there's no automated fall-back logic right now that would do the same out of tools/include/uapi/asm-generic/bpf_perf_event.h. The usual convention today is to add a include/[uapi/]asm/ equivalent that would pull in the correct arch header or generic one as fall-back, all ifdef'ed based on compiler target definition. It's similarly done also in other cases such as tools/include/asm/barrier.h, thus adapt the same here.

tools/include: Remove ACCESS_ONCE()

2017-12-12T12:22:10Z

There are no longer any usersapce uses of ACCESS_ONCE(), so we can remove the definition from our userspace , which is only used by tools in the kernel directory (i.e. it isn't a uapi header). This patch removes the ACCESS_ONCE() definition, and updates comments which referred to it. At the same time, some inconsistent and redundant whitespace is removed from comments. Tested-by: Paul E.

kmemcheck: rip it out for real

2017-12-08T21:40:17Z

Commit 4675ff05de2d ("kmemcheck: rip it out") has removed the code but for some reason SPDX header stayed in place. This looks like a rebase mistake in the mmotm tree or the merge mistake. Let's drop those leftovers as well. Signed-off-by: Michal Hocko Signed-off-by: Linus Torvalds

selftests/bpf: sync kernel headers and introduce arch support in Makefile

2017-12-05T14:02:41Z

Synchronize the uapi kernel header files which solves the broken uapi export of pt_regs. Because of arch-specific uapi headers, extended the include path in the Makefile. With this change, the test_verifier program compiles and runs successfully on s390.
