Linux kernel source tree
b478e162f2
The linux/pci.h and aspm.c files define their own sets of link state related defines which are almost the same. Consolidate the use of defines into those defined by linux/pci.h and expand PCIE_LINK_STATE_L0S to match earlier ASPM_STATE_L0S that includes both upstream and downstream bits. Rename also the defines that are internal to aspm.c to start with PCIE_LINK_STATE for consistency. While the PCIE_LINK_STATE_L0S BIT(0) -> (BIT(0) | BIT(1)) transformation is not 1:1, in practice aspm.c already used ASPM_STATE_L0S that has both bits enabled except during mapping. While at it, place the PCIE_LINK_STATE_CLKPM define last to have more logical grouping. Use static_assert() to ensure PCIE_LINK_STATE_L0S is strictly equal to the combination of PCIE_LINK_STATE_L0S_UP/DW.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
