[PATCH] kexec-tools, ppc64: fix build error on ppc64

[Michael Neuling]

6adc05c6e3fdbc8b9f5d915af78ca05d0a09cb17 "some kexec MIPS
improvements" broke pp64 as it turned on -Werror for all archs.

This fixes the warning and hence ppc64 building.

[PATCH] kexec-tools: don't include every archs Makefile

[Michael Neuling]

This patches changes the kexec/Makefile to only include the required
arch Makefile.  

Including all arch Makefiles causes unexpected results as changing one
archs Makefile effects all other archs.

ppc64 recently broke surprisingly because
6adc05c6e3fdbc8b9f5d915af78ca05d0a09cb17 "some kexec MIPS
improvements" added "CFLAGS +=-Wall -Werror" to
kexec/arch/mips/Makefile.  This shouldn't happen.

Horms: Tested by compiling on x86 and ppc64, but probably needs
testing on other archs before being committed.

Unfortunately this breaks make tarball - only kexec/arch/$ARCH is
included in the tarball.

Perhaps we could introduce $(ARCH)_FLAGS, which I think is
consistent with the handling of other variables by the kexec build.

I figured it might break something :-)

BTW make tarball works here.

Seems like a bit of a band aid.

It still seems pretty broken that we use arch/mips/Makefile for ppc64.

Looking at 6adc05c6e3fdbc8b9f5d915af78ca05d0a09cb17 and trying to work
out how it broke ppc64 was pretty annoying.

I agree that its entirely non-obvious and could be improved :-)

It would be nice to also remove the no-longer-needed casts.

Thanks.

While I'm very much in favour of using -Werror for testing
and these kind of patches are great, I think that -Werror
by default is rather silly. We can't control what will be
a warning in the future and sometimes fixing warnings isn't
appropriate - for instance there are warnings in fs2dt.c at
the moment, that is currently considered an upstream problem.

In short, this patch is great. But I plan to also remove -Werror
as the default now that its been brought to my attention.

Revert this portion of recent MIPS changes as it actually effects the
CFLAGS for all architectures.  Moreover I'm somewhat dubious about
defaulting to -Werror for any architecture.

Date: Wed, 5 May 2010 13:33:21 +1000
Subject: [PATCH] build: Don't modify CFLAGS in kexec/arch/mips/Makefile

Revert this portion of recent MIPS changes as it actually effects the
CFLAGS for all architectures.  Moreover I'm somewhat dubious about
defaulting to -Werror for any architecture.

Plan was to have -Werror only for mips. Thanks for fixes.
