[Linux-ia64] Re: Announce: kdb v2.0 is available for kernel 2.4.17

[Xavier Bru]

We must take care that the common KDB patch (kdb-v2.0-2.4.17-common-3)
conflicts with the IA64 patch on 2.4.17(linux-2.4.17-ia64-011226.diff). (needs to merge both patches).
I did not notice that first time and got a strange KDB behavior ( kdb_init()
was not called, and no way to quit kdb after breaking into it ).

That is due to the ia64 patch adding CONFIG_PERMON patches into
init/main.c.  AFAICT there is no reason that this patch cannot be sent
to Marcelo to reduce the footprint of the ia64 patch on common code.

David, can you send these ia64 patches to Marcelo for inclusion in base
kernel?  If you are too busy I will package them up and send them.

  Documentation/Configure.help
  Documentation/kernel-parameters.txt
  init/main.c
  Makefile (second chunk only, adding AFLAGS_KERNEL)
  include/linux/mm.h (just to reserve the bits)
  include/linux/prctl.h (reserve the bits)
  include/linux/time.h
  kernel/ksyms.c
  kernel/signal.c
  kernel/sys.c

The list above excludes anything that might affect other architectures.
The patch to ensure that the console variables are contiguous is
already in 2.4.18-pre1.

I would like to get crc32 in base as well but I believe that another
person has been working on this as well.  If you like I will reconcile
the two versions and get one crc32 into base kernel.

Jeff Garzik and I have I've been unsuccessful in getting crc32 into the base
kernels.  Jeff sent the patch once, I've sent the patch repeatedly.  Marcelo
looked at it and said he wanted to see it in 2.5.x first.  Linus has been
silent.

http://domsch.com/linux/patches/crc32/2.5.2-pre7/ has the current
implementation, broken into several smaller parts, and provided as one big
patch too.  Two additional drivers (de2140x.c and sis900.c) were modified
*after* the patch set was created and are also there; the
drivers/net/Makefile.lib needs to be touched to add those drivers to the
list - I haven't done that yet.

Keith, if you can get it in, I'd be glad for it.

Bugger is, when 2.5.x does away with fs/partitions/*, my need for the crc32
function in the kernel to support GPT dies too.  Progress I guess...

Thanks,
Matt

That would be fine with me.  But could you send me the patch for a
final sanity check before sending it off to Marcelo?

Also, do not send it the linux/mm.h changes.  Due to the multiple
memory attribute issue, I'm not sure the VM_NONCACHED and
VM_WRITECOMBINED are such good ideas (besides, I don't think they're
really needed anymore).

Matt was working on this.  Is that who you were referring two?  Yes,
there is no reason this patch shouldn't be in 2.4.xx as far as I'm
concerned.

Thanks,

Well, what do you know, Linus applied it for 2.5.2-pre12.
As for 2.4.x, I'll give it a week or so in 2.5.x to prove to Marcelo it's
stable, and then re-submit there.

Thanks,
Matt
