2018-08-27blk-wbt: improve waking of tasksJens Axboe
We have two potential issues: 1) After commit 2887e41b910b, we only wake one process at the time when we finish an IO. We really want to wake up as many tasks as can queue IO. Before this commit, we woke up everyone, which could cause a thundering herd issue. 2) A task can potentially consume two wakeups, causing us to (in practice) miss a wakeup. Fix both by providing our own wakeup function, which stops __wake_up_common() from waking up more tasks if we fail to get a queueing token. With the strict ordering we have on the wait list, this wakes the right tasks and the right amount of tasks. Based on a patch from Jianchao Wang <jianchao.w.wang@oracle.com>.

2018-08-27Revert "scsi: core: avoid host-wide host_busy counter for scsi_mq"Ming Lei
This reverts commit 328728630d9f2bf14b82ca30b5e47489beefe361. There is fundamental issue in commit 328728630d9f2bf1 (scsi: core: avoid host-wide host_busy counter for scsi_mq) because SCSI's host busy counter may not be same with counter of blk-mq's inflight tags, especially in case of none io scheduler. We may switch to other approach for addressing this scsi_mq's performance issue, such as percpu counter or kind of ways, so revert this commit first for fixing this kind of issue in EH path, as reported by Jens.

2018-08-27scsi: lpfc: Correct MDS diag and nvmet configurationJames Smart
A recent change added some MDS processing in the lpfc_drain_txq routine that relies on the fcp_wq being allocated. For nvmet operation the fcp_wq is not allocated because it can only be an nvme-target. When the original MDS support was added LS_MDS_LOOPBACK was defined wrong, (0x16) it should have been 0x10 (decimal value used for hex setting). This incorrect value allowed MDS_LOOPBACK to be set simultaneously with LS_NPIV_FAB_SUPPORTED, causing the driver to crash when it accesses the non-existent fcp_wq. Correct the bad value setting for LS_MDS_LOOPBACK. Fixes: ae9e28f36a6c ("lpfc: Add MDS Diagnostic support.")

2018-08-27x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+Andi Kleen
On Nehalem and newer core CPUs the CPU cache internally uses 44 bits physical address space. The L1TF workaround is limited by this internal cache address width, and needs to have one bit free there for the mitigation to work. Older client systems report only 36bit physical address space so the range check decides that L1TF is not mitigated for a 36bit phys/32GB system with some memory holes. But since these actually have the larger internal cache width this warning is bogus because it would only really be needed if the system had more than 43bits of memory. Add a new internal x86_cache_bits field. Normally it is the same as the physical bits field reported by CPUID, but for Nehalem and newerforce it to be at least 44bits. Change the L1TF memory size warning to use the new cache_bits field to avoid bogus warnings and remove the bogus comment about memory size.
