Kbuild: sync with Linux 3.16-rc1

The merge window for Linux 3.16 is closed and Linux 3.16-rc1 is out now.

During the merge window, various Kbuild-related updates were merged into the upstream.

This series imports them to U-Boot.

Masahiro Yamada (5):
kbuild: move extra gcc checks to scripts/Makefile.extrawarn
kbuild: sync mixed targets handling with Linux 3.16-rc1
cosmetic: kbuild: clean-up coding style (sync with Linux 3.16-rc1)
kbuild: Use relative path when possible
scripts: objdiff: sync with Linux 3.16-rc1

1.9.1

This commit was imported from Linux Kernel:
commit a86fe353 written by me.

W=... provides extra gcc checks.

Having such code in scripts/Makefile.build results in the same flags being added to KBUILD_CFLAGS multiple times becuase scripts/Makefile.build is invoked every time Kbuild descends into the subdirectories.

Since the top Makefile is already too cluttered, this commit moves all of extra gcc check stuff to a new file scripts/Makefile.extrawarn, which is included from the top Makefile.

1.9.1

"make %_config all" was supported for the first time in U-Boot:
commit 53bca5ab
kbuild: support simultaneous board configuration and "make all"

Surprisingly it had not been working in Linux Kernel for a long time.

So I sent back the patch to the Linux Kbuild community and it was accepted with a little code improvement, at commit 9319f453.

Now, you can do "make defconfig all" or "make %_defconfig all" in Linux too.

This commit updates some scripts to fill the code-diff between Linux and U-Boot.

1.9.1

Hello Masahiro,

There is some issue with this in current master I guess. I haven't bothered too much, but I think the one liner cause gcc to be called even if both compilers are set to clang. With a separate config and make step I have never seen such behavior. I only noticed it on FreeBSD though since gcc is not installed there and actually errors, so it might be awk / sed related as well.

Anyway, perhaps rings a bell...

Regards,
Jeroen

Could you tell me how to reproduce the problem?

As far as I tested on FreeBSD where gcc is not installed, I do not see that problem.

This is my repeat steps.
It fails on the halfway, but at least Clang is used for both HOSTCC and CC.

Hello Masahiro,

Weird, below is my build output on current master with some floating patches to make the build succeed [1] (well I didn't send the time.h yet since I don't understand how linux gets away with that at the moment)

As mentioned I have no clue why it fails and haven't looked into it. Just noticed it didn't work.

Hi Jeroen,

I followd the same steps as you did,
using your GitHub repository.

In my test, gcc was not called during the build.

My log is as follows:

1.9.1

Some regressions about these commits have been reported to linux-kbuild ML.

It might be too early to import them to U-boot, so I decided to postpone this patch.

I will change its status to RFC.

1.9.1

I see you saw there's problems been reported and have moved this to RFC. My thoughts on this right now are that as a rule of thumb we should:
1) If our merge window and kernel merge window line up (say -rc1 kernel came out, and we are -rc1 or haven't yet snapped -rc1), sync up, and stay in sync to release on the kernel side (as close as possible)
2) If our merge windows aren't in sync, just stick with kernel release.

Thanks!

Hi Tom,

I understand the rule.

But can I still request to apply only this one?
http://patchwork.ozlabs.org/patch/359996/

It is purely cosmetic and I am really sure it is safe.

Best Regards
Masahiro Yamada

Deal, thanks.
