2017-06-15nvme-pci: Remove watchdog timerKeith Busch1-67/+56
The controller status polling was added to preemptively reset a failed controller. This early detection would allow commands that would normally timeout a chance for a retry, or find broken links when the platform didn't support hotplug. This once-per-second MMIO read, however, created more problems than it solves. This often races with PCIe Hotplug events that required complicated syncing between work queues, frequently triggered PCIe Completion Timeout errors that also lead to fatal machine checks, and unnecessarily disrupts low power modes by running on idle controllers. This patch removes the watchdog timer, and instead checks controller health only on an IO timeout when we have a reason to believe something is wrong. If the controller is failed, the driver will disable immediately and request scheduling a reset.

2017-06-15nvme-pci: remap BAR0 to cover admin CQ doorbell for large strideXu Yu2-22/+44
The existing driver initially maps 8192 bytes of BAR0 which is intended to cover doorbells of admin SQ and CQ. However, if a large stride, e.g. 10, is used, the doorbell of admin CQ will be out of 8192 bytes. Consequently, a page fault will be raised when the admin CQ doorbell is accessed in nvme_configure_admin_queue(). This patch fixes this issue by remapping BAR0 before accessing admin CQ doorbell if the initial mapping is not enough.

2017-06-12compiler, clang: properly override 'inline' for clangLinus Torvalds1-1/+2
Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused static inline functions") just caused more warnings due to re-defining the 'inline' macro. So undef it before re-defining it, and also add the 'notrace' attribute like the gcc version that this is overriding does. Maybe this makes clang happier.
