The PCI adapter's firmware isn't fully functional when the PCIe bus
link is up. 1.8 seconds are needed for the firmware to be completely
functional according to the PCI bus settlement time (after reset)
we have in EEH code (EEH_PE_RST_SETTLE_TIME). Without the delay, the
driver fails to initialize

There was an assumption that flush_tmregs_to_thread() would only be

This patch employs the refcount in struct pci_controller to track
the references from PCI devices and buses (struct pci_dev/pci_bus).

The adapter file descriptor was previously cached within the kernel

required to perform a close on the adapter file descriptor.

Caching the adapter file descriptor and performing a close on behalf
of an application is a poor design. This is due to the fact that once
a file descriptor in installed, it is free to be altered without the
knowledge of the cxlflash driver. This can lead to inconsistencies
between the application
Currently, context user references are tracked via the list of LUNs
that have attached to the context. While convenient, this is not
intuitive without a deep study of the code and is inconsistent with
the existing reference tracking patterns within the kernel. This design

The context removal routine requires access to the owning adapter

This patch set contains various code improvements and cleanups that

Since v4.8-rc1, the I2C core will print detailed information when adding an I2C
adapter fails. So, drivers can skip this now.
I am still undecided if I apply this as a single patch or break it out. But for

When we introduced the little endian support, we added the endian flags
to CC directly using override. I don't know the history of why we did
that, I suspect no one does.

commit 190ce8693c23eae09ba5f303a83bf2fbeb6478b1 upstream.
Currently we have 2 segments that are bolted for the kernel linear

faulted in.

Otherwise, the stack frame is corrupted when writing to
