Build regressions/improvements in v4.3-rc3

Build regressions/improvements in v4.3-rc3

[Geert Uytterhoeven]

Below is the list of build error/warning regressions/improvements in
v4.3-rc3[1] compared to v4.2[2].

Summarized:
  - build errors: +8/-8
  - build warnings: +161/-97

JFYI, when comparing v4.3-rc3[1] to v4.3-rc2[3], the summaries are:
  - build errors: +8/-12
  - build warnings: +49/-181

Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.

As I haven't mastered kup yet, there's no verbose summary at
http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/v4.3-rc3.summary.gz

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.

Not every randconfig failure is a kernel problem.  Here's an example:

Physical address of main memory (PHYS_OFFSET) [] (NEW) aborted!

Console input/output is redirected. Run 'make oldconfig' to update configuration.

This needs someone to provide a value, which means these failures are
not in fact failures of the kernel, but a failure of the build system
to anticipate that there may be Kconfig questions that need input.

So, these ones should be ignored.

Also, a great many of the failures are due to the build toolchain not
supporting -fstack-protector-strong.  I think it's absolutely right
for the build to error out if you enable a kernel feature which requires
toolchain support, but the toolchain does not support that feature.

What this means is that the build results from kissb are less than
useful - without spending ages looking at every single build, it's
hard to find the real failures we care about.

I'd suggest that either the randconfig is seeded to ensure that
CONFIG_CC_STACKPROTECTOR_STRONG is always disabled in ARM randconfigs,
or that the ARM toolchain is updated to support this feature.

Usually I ignore them. But as this was the only failure to report (I ignore
R_PPC64_REL24 failures, too), I thought to kick the kbuild people (and the
ARM list, as it was the ARM randconfig that failed) for once.

Or that it's impossible to enable this feature if your toolchain doesn't
support it?

I think that would require kconfig to call out to the compiler to run
a test build.  This kind of thing has been talked about in the past
but the feature never seems to appear - probably because it would end
up increasing the kconfig startup time in every case.

Given the number of existing "$(call cc-option, ...)" in Makefiles, the effect
on kconfig startup time should be small.
