[parisc-linux] kdb patches for -pa23 ... moooo!

[joel.soete@freebel.net]

Hi Carlos,

Well I well get your patch which I apply successfully against pa23.

On the other hand, I also reach to rebuild a toolchain with gcc-3.1 (some
difficulties with 3.2).

So to try to figure out what the problem is with kernel IP compile with gcc >
3.1, I try to compile kernel 2.4.18-pa23-kdb with gcc 3.1. But without any
experience with kdb the operation failled with following message:

gcc -D__KERNEL__

Hmm the patch put kdb.h in include/asm-parisc but all #include refer to linux/kdb.h?

There should be also some problem with my .config where I select 
CONFIG_KDB=y
CONFIG_KDB_MODULES=y
# CONFIG_KDB_OFF is not set
CONFIG_KALLSYMS=y

(the rest is obtain for a common make oldconfig for PA7000 processor type)

Thanks in advance for additionnal help,
    Joel
