[PATCH v2 0/7] uapi: export all headers under uapi directories

Here is the v2 of this series. The first 5 patches are just cleanup: some exported headers were still under a non-uapi directory. The patch 6 was spotted by code review: there is no in-tree user of this functionality. The last patch remove the use of header-y. Now all files under an uapi directory

[PATCH v2 7/7] uapi: export all headers under uapi directories

Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After

[PATCH v2 5/7] Makefile.headersinst: cleanup input files

After the last four patches, all exported headers are under uapi/, thus input-files2 are not needed anymore. The side effect is that input-files1-name is exactly header-y. Note also that unput-files3-name is genhdr-y. Signed-off-by: Nicolas Dichtel --- scripts/Makefile.headersinst | 34

[PATCH 0/4] cxlflash: Enhancements, cleanup and fixes

This patch series includes an enhancement to support a new command queuing model and also cleans up prints throughout the driver. The last patch in the series fixes a racing issue. The series is based upon v4.10-rc2, intended for 4.11 and is bisectable. Matthew R. Ochs (3): cxlflash: Refactor c

[PATCH 1/4] cxlflash: Refactor context reset to share reset logic

From: "Matthew R. Ochs" As staging for supporting hardware with different context reset registers but a similar reset procedure, refactor the existing context reset routine to move the reset logic to a common routine. This will allow hardware with a different reset register to leverage existing c

[PATCH 2/4] cxlflash: Support SQ Command Mode

From: "Matthew R. Ochs" The SISLite specification outlines a new queuing model to improve over the MMIO-based IOARRIN model that exists today. This new model uses a submission queue that exists in host memory and is shared with the device. Each entry in the queue is an IOARCB that describes a tra

[PATCH 3/4] cxlflash: Cleanup prints

From: "Matthew R. Ochs" The usage of prints within the cxlflash driver is inconsistent. This hinders debug and makes the driver source and log output appear sloppy. The following cleanups help unify the prints within cxlflash: - move all prints to dev-* where possible - transition all hex prin

[PATCH 4/4] cxlflash: Cancel scheduled workers before stopping AFU

When processing an AFU asynchronous interrupt, if the action results in an operation that requires off level processing (a link reset for example), the worker thread is scheduled. In the meantime a reset event (i.e.: EEH) could unmap the AFU to recover. This results in an Oops when the worker threa

[PATCH v3 0/3] powerpc/pseries: Perform PRRN topology updates in kernel

Formerly, when we received a PRRN rtas event, device tree updating was performed in the kernel and the actual topology updating was performed in userspace. This was necessary as in order to update the topology for memory, we must perform a hot remove and a subsequent hot add and until recently, mem

[PATCH v3 1/3] powerpc/pseries: Make the acquire/release of the drc for memory a seperate step

When adding and removing LMBs we should make the acquire/release of the DRC a separate step to allow for a few improvements. First this will ensure that LMBs removed during a remove by count operation are all available if a error occurs and we need to add them back. By first removeing all the LMBs

[PATCH v3 2/3] powerpc/pseries: Introduce memory hotplug READD operation

Currently, memory must be hot removed and subsequently re-added in order to dynamically update the affinity of LMBs specified by a PRRN event. Earlier implementations of the PRRN event handler ran into issues in which the hot remove would occur successfully, but a hotplug event would be initiated f

[PATCH v3 3/3] powerpc/pseries: Update affinity for memory and cpus specified in a PRRN event

Extend the existing PRRN infrastructure to perform the actual affinity updating for cpus and memory in addition to the device tree updating. For cpus, dynamic affinity updating already appears to exist in the kernel in the form of arch_update_cpu_topology. For memory, we must place a READD operatio
