Never mind.  Linus pulled it five days ago as I type this.  The fixes
obviously didn't make it in time for 4.13-final, but should be in 4.14.

I guess that commit hasn't made it into Linus' tree :-(.  If the patch
is short, please forward if you would be so kind.  Many thanks in
advance.

I *think* what I want to do is the equivalent of the ".S" file
'.text --> .section .alphalib,"ax"' substitution for the affected ".c"
files in "arch/alpha/lib".  At the risk of baring my ignorance to the
world, is there a straightforward way of accomplishing that?  The
"objdump" tool confirms it's not a strict renaming of one section
to another: the ".text" section still exists in the compiled ".S"
files that were patched.

The kernel seemed to be in good shape after my two pull requests were
merged. (commit dd689a68bc3 for 4.13 and commit 6caffe21dde for

[BUG] 4.13.0 kernel build error on Alpha

2017-09-10 Thread Bob Tracy 
Here we go again :-(.  Tool versions as follows:

gcc version 7.2.0 (Debian 7.2.0-3)
GNU ld (GNU Binutils for Debian) 2.29 (binutils 2.29-9)

Note evidence of the ".alphalib" section patch first tried with the 4.9
kernel source.  It has worked well up through 4.12.  I didn't try
building any of the 4.13 release candidates because of all the compiler
updates that came through during that time.

I was able to install netboot sparc64 ldom (but not latest sid version
, which is too big to load by OBP. There's also #645657 debian bug,
but somehow it got closed).

Also, installed ppc64 LPAR, failed to install yaboot and using grub2
on Power8 server, but that installation wasn't netboot, but usual
iso/cdrom install.

I could probably try to install test ppc64 lpar with netboot just to
check how it will go, but i need to know where do i get netboot image,
since https://cdimage.debian.org/cdimage/ports/ does not have netboot
images.

Thanks

So far, the ride for ppc64 has been *extremely* painful. This is not
necessarly due to your efforts, but it feels a lot like nobody ever has
tried to set up Debian on a G5 using netboot.

So far (might be incomplete, and I'm both tired and fairly upset):

* Any reasonable documentation on this anywhere? No about how to set up
  DHCP/TFTP server, I've done this many time. But what about which files
  are needed, and how to provide a netboot-adjusted yaboot.conf, and
  mostly: How to make yaboot make using it?

* The OF bootloader needs two rounds to load yaboot.

* yaboot should either get a decent on-line help or see bitrot.

* yaboot's "conf /path/to/config" command, when initially using netboot,
  happiliy ignores the file name but retrieves 01-xx-yy-xx-yy-xx-yy
  using TFTP instead.

* After a lot of trickery, the installer's vmlinux now gets loaded. At a
  whopping 6 kbyte/sec (yes: six kilobytes). Just to remind you, kernel
  and initrd take some 35 megabytes, and the G5 has already turned to
  airplane mode. My neighbors will love me.

This isn't getting anywhere useful soon.
