2018-10-13x86/vdso: Fix vDSO syscall fallback asm constraint regressionAndy Lutomirski
commit 02e425668f5c9deb42787d10001a3b605993ad15 upstream. When I added the missing memory outputs, I failed to update the index of the first argument (ebx) on 32-bit builds, which broke the fallbacks. Somehow I must have screwed up my testing or gotten lucky. Add another test to cover gettimeofday() as well.

2018-10-13selftests/x86: Add clock_gettime() tests to test_vdsoAndy Lutomirski
commit 7c03e7035ac1cf2a6165754e4f3a49c2f1977838 upstream. Now that the vDSO implementation of clock_gettime() is getting reworked, add a selftest for it. This tests that its output is consistent with the syscall version.

2018-09-26selftest: timers: Tweak raw_skew to SKIP when ADJ_OFFSET/other clock ↵John Stultz
adjustments are in progress [ Upstream commit 1416270f4a1ae83ea84156ceba19a66a8f88be1f ] In the past we've warned when ADJ_OFFSET was in progress, usually caused by ntpd or some other time adjusting daemon running in non steady sate, which can cause the skew calculations to be incorrect. Thus, this patch checks to see if the clock was being adjusted when we fail so that we don't cause false negatives.

2018-09-19tools/testing/nvdimm: kaddr and pfn can be NULL to ->direct_access()Huaisheng Ye
[ Upstream commit 45df5d3dc0c7289c1e67afe6d2ba806ad5174314 ] The mock / test version of pmem_direct_access() needs to check the validity of pointers kaddr and pfn for NULL assignment. If anyone equals to NULL, it doesn't need to calculate the value. If pointer equals to NULL, that is to say callers may have no need for kaddr or pfn, so this patch is prepared for allowing them to pass in NULL instead of having to pass in a local pointer or variable that they then just throw away.

2018-09-15selftests/powerpc: Kill child processes on SIGINTBreno Leitao
[ Upstream commit 7c27a26e1ed5a7dd709aa19685d2c98f64e1cf0c ] There are some powerpc selftests, as tm/tm-unavailable, that run for a long period (>120 seconds), and if it is interrupted, as pressing CRTL-C (SIGINT), the foreground process (harness) dies but the child process and threads continue to execute (with PPID = 1 now) in background. In this case, you'd think the whole test exited, but there are remaining threads and processes being executed in background. Sometimes these zombies processes are doing annoying things, as consuming the whole CPU or dumping things to STDOUT. This patch fixes this problem by attaching an empty signal handler to SIGINT in the harness process. This handler will interrupt (EINTR) the parent process waitpid() call, letting the code to follow through the normal flow, which will kill all the processes in the child process group. This patch also fixes a typo.

[ Upstream commit cd4a6f3ab4d80cb919d15897eb3cbc85c2009d4b ] The subpage_prot syscall is only functional when the system is using the Hash MMU. Since commit 5b2b80714796 ("powerpc/mm: Invalidate subpage_prot() system call on radix platforms") it returns ENOENT when the Radix MMU is active. Currently this just makes the test fail. Additionally the syscall is not available if the kernel is built with 4K pages, or if CONFIG_PPC_SUBPAGE_PROT=n, in which case it returns ENOSYS because the syscall is missing entirely. So check explicitly for ENOENT and ENOSYS and skip if we see either of those.
