After the request to reduce the kernels to e.g. SMP-only, my thought was
to provide only 32bit-UP and 64bit SMP kernels.
To be sure I asked on the parisc mailing list. The whole thread can be read
here:
http://comments.gmane.org/gmane.linux.ports.parisc/5283
Summary:
- yes, there exists quite some 32bit-only parisc SMP machines.
- the J5600 is SMP capable in both 32bit and 64bit mode, but currently it
only boots Linux with a 32bit SMP kernel and crashes with a 64bit SMP
kernel.
We are working on resolving this...

Looks like you fixed this one:

parisc: Do not crash 64bit SMP kernels on machines with = 4GB RAM
Can you send a new config patch?
actually I worked on a few more issues which were mentioned here in this
bugreport... :-)
Attached is a new patch - I hope I could address most questions.
Some notes:
- CONFIG_DEVTMPFS wasn't set before - needed to be able to boot
- CONFIG_HP_SDC_RTC - RTC driver is buggy and not needed - we use BIOS/PDC
- CONFIG_MEGARAID_NEWGEN=y - use new megaraid instead of old. Old one crashed
one of my machines.
- CONFIG_MLONGCALLS=y - needed for 64bit kernel.
This is fixed upstream with kernel 3.13 and can be removed as soon as the
debian kernel uses 3.13.
Upstream commits (which I don't plan to backport):
b8d8fccd68c36a19fef9768d06aa150bbc8cdd74
161bd3bf60ee2c5765455ad3e3da967d03449f4a
5ecbe3c3c690b5ab493c730c317475287a9e8b45
- CONFIG_PATA_SIL680=m, you suggested to use this one instead of SIIMAGE.
Worked.
SIL680-patch upstream for 3.13: a16ab68ee96005382738c706fd06bdd874d9185b
- CONFIG_E1000=m, needed, existing configs only included e100.
- AGP/DRM are now modules. Otherwise we don't have any output on the C8000
machines.
As suggested I dropped parisc-smp and parisc64, still keeping parisc and
parisc64-smp.
We now can switch to use gcc-4.8 like the other arches.
The control-file needs update to reflect this (not included here). Can you
modify it by hand, if not, I can send a patch for that.
