Hi Masahiro,
I noticed that "install" seems to be no longer PHONY, or at least if I
have a file/directory called install then the build doesn't run.
eg:
$ touch install
$ make install
make: 'install' is up to date.
$ rm install
$ make install
LDS arch/powerpc/boot/zImage.lds
WRAP arch/powerpc/boot/zImage.pseries
WRAP arch/powerpc/boot/zImage.epapr
In the past the presence of an install file/directory didn't have any
affect.
It seems this changed in:
d79424137a73 ("kbuild: do not update config when running install targets")
Was that expected?
cheers

I think the reason is
'install' is not specified as a phony target.
You can add 'PHONY += install' to fix it.
PHONY += install # please add this!
install:
$(Q)$(MAKE) $(build)=$(boot) install
Please do so in both arch/powerpc/Makefile and
arch/powerpc/boot/Makefile.

I do not think commit is related.
Prior to this commit, I still see the same issue.
$ git checkout d7942413^
$ touch install
$ make -s ARCH=powerpc allnoconfig
$ make ARCH=powerpc install
make: 'install' is up to date.

Oh lol, sorry I didn't realise install was in the arch Makefile.

Hmm weird. I did bisect it:
# bad: [d79424137a7312d381d131d707a462440c0e8df9] kbuild: do not update config when running install targets
git bisect bad d79424137a7312d381d131d707a462440c0e8df9
# good: [9c2af1c7377a8a6ef86e5cabf80978f3dbbb25c0] kbuild: add .DELETE_ON_ERROR special target
git bisect good 9c2af1c7377a8a6ef86e5cabf80978f3dbbb25c0
# first bad commit: [d79424137a7312d381d131d707a462440c0e8df9] kbuild: do not update config when running install targets
But you're right. I must have messed something up while bisecting.
Sorry for the noise.
cheers
