[PATCH] Re: KDB in ameslab

[linas at austin.ibm.com]

Hi,

Resending because the ppc64 mail list manager bounced the message
because the patch was too big.

This patch brings the ameslab ppc64 tree up to the current
level of KDB (v 4.3 hot from the sgi ftp site as of two days ago)
Note that since ameslab currently has kdb 4.1(?) in it, that
this patch has the effect of undoing the old kdb as it adds the
new kdb.

Rather than attaching, because of file size limits, I've put a new,
slightly improved patch at:

 http://www-124.ibm.com/linux/patches/?patch_id=1384
(it may take 1-24 hours for the above URL to bcome valid).

The 'slight improvement' includes:

-- addition of missing dis-asm.h
-- fixing CONFIG_KDB_MODULES so that kdb modules work

This patch should apply cleanly to the ameslab tree.
