This results in initialization sequence not sent to the card during re-insertion. Fix it here by adding sdhci_omap_set_power_mode to update power_mode. This function can also be used later to perform operations that are specific to a power mode (e.g, disable tuning during power off). Signed-off-by:

Re-enable deep flush so that users always have a way to be sure that a write makes it all the way out to media. Writes from the PMEM driver always arrive at the NVDIMM since movnt is used to bypass the cache, and the driver relies on the ADR (Asynchronous DRAM Refresh) mechanism to flush write buffers on power failure. The Deep Flush mechanism is there to explicitly write buffers to protect against (rare) ADR failure. This change prevents a regression in deep flush behavior so that applications can continue to depend on fsync() as a mechanism to trigger deep flush in the filesystem-DAX case.

Filesystem-DAX is incompatible with 'longterm' page pinning. Without page cache indirection a DAX mapping maps filesystem blocks directly. This means that the filesystem must not modify a file's block map while any page in a mapping is pinned. In order to prevent the situation of userspace holding of filesystem operations indefinitely, disallow 'longterm' Filesystem-DAX mappings. RDMA has the same conflict and the plan there is to add a 'with lease' mechanism to allow the kernel to notify userspace that the mapping is being torn down for block-map maintenance. Perhaps something similar can be put in place for vfio. Note that xfs and ext4 still report: "DAX enabled. Warning: EXPERIMENTAL, use at your own risk" ...at mount time, and resolving the dax-dma-vs-truncate problem is one of the last hurdles to remove that designation. Acked-by:

The architecture specification says (for 64-bit systems): PDC is a per processor resource, and operating system software must be prepared to manage separate pointers to PDCE_PROC for each processor. The address of PDCE_PROC for the monarch processor is stored in the Page Zero location MEM_PDC. The address of PDCE_PROC for each non-monarch processor is passed in gr26 when PDCE_RESET invokes OS_RENDEZ. Currently we still use one PDC for all CPUs, but in case we face a machine which is following the specification let's warn about it. Signed-off-by:
