Hauke Mehrtens cb0c8da7c2 kernel: take bcm47xx_nvram.h from kernel and not backports
compat-wireless/backports now contains a bcm47xx_nvram.h file to
backport some of the functions in it which are used by the bcmfmac
driver. This file just checks for the kernel versions and provide an
empty implementations on older kernel versions. This is OK on most
systems, but on bcm47xx / bcm53xx systems we want to call the real
functions here. This commit removes the file from backports in our
build process like we do it with the bcma and ssb header files. Instead
we add a recent version into our kernel so all code uses only one
header file. On bcm47xx / bcm53xx the real implementations of this code
will be used.

Subject: [PATCH] perf build: Do not fail on missing Build file
Allow nesting into directories without Build file. Currently we force
include of the Build file, which fails the build when the Build file is
missing.
We already support empty *-in.o' objects if there's nothing in the
directory to be compiled, so we can just use it for missing Build file
cases.
Also adding this case under tests.
