Thomas Renninger 05c36e5adf tools/power/acpi: Serialize Makefile
Before this patch you get tools/power/acpi/Makefile.rules
included in parallel trying to copy KERNEL_INCLUDE multiple
times:

make -j20 acpi
  DESCEND  power/acpi
  DESCEND  tools/acpidbg
  DESCEND  tools/acpidump
  DESCEND  tools/ec
  MKDIR    include
  MKDIR    include
  MKDIR    include
  CP       include
  CP       include
cp: cannot create directory '/home/abuild/rpmbuild/BUILD/linux-5.7.7+git20200917.10b82d517648/tools/power/acpi/include/acpi': File exists
make[2]: *** [../../Makefile.rules:20: /home/abuild/rpmbuild/BUILD/linux-5.7.7+git20200917.10b82d517648/tools/power/acpi/include] Error 1
make[1]: *** [Makefile:16: acpidbg] Error 2
make[1]: *** Waiting for unfinished jobs....

with this patch each subdirectory will be processed serialized:

  DESCEND  power/acpi
  DESCEND  tools/acpidbg
  MKDIR    include
  CP       include
  CC       tools/acpidbg/acpidbg.o
  LD       acpidbg
  STRIP    acpidbg
  DESCEND  tools/acpidump
  CC       tools/acpidump/apdump.o
...
  LD       acpidump
  STRIP    acpidump
  DESCEND  tools/ec
  CC       tools/ec/ec_access.o
  LD       ec
  STRIP    ec

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.
