[PATCH] kernel.bbclass: Preserve generated headers

[PATCH] kernel.bbclass: Preserve generated headers

[Khem Raj]

asm/unistd.h includes asm/unistd_64.h on x86_64
and asm/unistd_32.h on i386 but these files are
generated files in 3.4 and when we do 'make clean' they get
deleted and it shows up as an error when building
external modules. May be its a 3.4 kernel bug may be not
but make clean should have left the tree in
a shape to build modules but it does not.

Probably we should run make modules_prepare after having
run make clean.

If we take the blanket protection, we should be able to drop the
bounds.h specific
case a the same time .. right ?

I'm ok with this, but I can run a test with 'make modules_prepare'
being run if you
already haven't.

Cheers,

There just doesn't seem to be a good way to do what we need to do here.
modules_prepare will build scripts, which we don't want, but clean kills
all the generated files.

This sounds like a good Linux kernel bug for us to to take a look at
fixing upstream:

make modules_prepare_cross

or something simlar, so we can get what we need with proper make targets
and avoid this constant cherry picking of files.

Do you need all the generated files in arch/$ARCH/include/generated? Are
there any binaries in there?

No, different dirs (one is ARCH)

We really can't, this builds scripts, which we don't want as this
results in native binaries being installed on the target :(

We need some cross-build-system-friendly make targets for this.

Aha. I missed that, but can we back up a directory and take everything from
generated/* ? .. assuming your question about binaries being in those
directory is "no".

It isn't a "no" for the include/generated dir, just not sure about ARCH.
