kernel-yocto: 4.9 goodness

Hi all,

I'm sending this out so it can get some extra test cycles. I've built and booted core-image-kernel-dev/sato on qemu* with the 4.9 kernel and 4.9 libc-headers.

I didn't see any issues .. but there always seems to be one lurking.

I'm heading out of town for the holidays, so this commit does not switch qemu* to use 4.9 by default, but it does put the recipes and trees in place for upcoming work on new targets and -rt support.

So assuming that the libc-headers change survives some autobuilder cycles, this should be safe for merge.

Cheers,

Bruce

2.5.0

Bumping the linux-libc-headers to the 4.9 kernel variant. Since 4.9 will be a LTSI kernel, and there will be an associated linux-yocto it is worth moving to these headers sooner rather than later.

This commit also drops the 4.8 headers and sets 4.9 to be the default.

2.5.0

The autobuilder run (ross/mut 1dc1894e05) with this had a couple of issues:

*** ppp fails to build on musl:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=10853

*** ncurses fails in several builds, all gnu/stubs.h related:
ncurses was also upgraded in this AB run (CCing Huang Qiyu) but the failures seem more like libc related...

x32:
| nightly-x32/build/build/tmp/sysroots/qemux86-64/usr/include/gnu/stubs.h:10:27:
fatal error: gnu/stubs-64.h: No such file or directory

Thanks for the update. Not knowing much about musl, others have jumped in on these
in the past. I'll loop around and have a look at it if one of the musl users doesn't have an
idea as to what is up with ppp.

I'll have a look at these when I'm back in the office in January. x32 isn't something that I build, but I did build sato, so this is something specific to that config. Should be easy enough to reproduce on my builder.

Cheers,

Bruce

"Thou shalt not follow the NULL pointer, for chaos and madness await thee
at its end"

FYI: I was just able to build all variants on ncurses on the branches I have available.

I'm going to need a bit more direction on what branch/config to build to see this breakage.

Introducing the 4.9 kernel recipes. 4.9 will be a LTSI kernel, so we introduce these recipes with the intent that they'll replace 4.1 as the LTSI kernel, and other older kernels (i.e 4.4/4.8) once 4.9 shown to be stable.

linux-yocto-tiny and linux-yocto-rt are also part of this commit, but are placeholders while we wait for their content to be available. They will build, but provide nothing above the standard kernel at the moment.
