Masahiro Yamada bc7cd2dd1f kbuild: redo fake deps at include/ksym/*.h
Commit 0e0345b77a ("kbuild: redo fake deps at include/config/*.h")
simplified the Kconfig/fixdep interaction a lot.

For CONFIG_FOO_BAR_BAZ, Kconfig now touches include/config/FOO_BAR_BAZ
instead of the previous include/config/foo/bar/baz.h .

This commit simplifies the TRIM_UNUSED_KSYMS feature in a similar way:

  - delete .h suffix
  - delete tolower()
  - put everything in 1 directory

For EXPORT_SYMBOL(FOO_BAR_BAZ), scripts/adjust_autoksyms.sh now touches
include/ksym/FOO_BAR_BAZ instead of include/ksym/foo/bar/baz.h .

This is more precise, avoiding possibly unnecessary rebuilds.

  EXPORT_SYMBOL(FOO_BAR_BAZ)
  EXPORT_SYMBOL(_FOO_BAR_BAZ)
  EXPORT_SYMBOL(__FOO_BAR_BAZ)

were previously mapped to the same header, include/ksym/foo/bar/baz.h
but now are handled separately.

README

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 Restructured Text 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.
