Bug in Kernel 2.4.20

[Martin aus Mainz <martyausmainz@gmx.de>]

Hello,

today I tried to compile the 2.4.20 kernel.

I had the following error:

gcc -D__KERNEL__ -I/var/src/linux-2.4.20-pre7/include -Wall -Wstrict-prototypes
-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -I /var/src/linux-2.4.20-pre7/include/asm/gcc -G 0
-mno-abicalls -fno-pic -pipe -mcpu=r4600 -mips2 -Wa,--trap   -nostdinc -iwithprefix include -DKBUILD_BASENAME=binfmt_elf  -c -o

make[2]: *** [binfmt_elf.o] Error 1

After a search I found out, that some parts of "include/linux/elf.h" have changed.
There are some *_MIPS_* commands missing.

I added at line 42 the following:

#define EF_MIPS_ABI       0x0000f000
#define EF_MIPS_ABI2      0x00000020

and the error was gone.

The last problem I have is this, when the make try to build the vmlinux:

arch/mips/sgi-ip22/ip22-kern.o: In function 	'ip22_setup':
arch/mips/sgi-ip22/ip22-kern.o(.text.init+0xa44): undefined reference to 'console_setup'

and the vmlinux is not created. I searched around with google, but didn't find something to console_setup-

I changed a lot in the config from ARC to SGI Newport Console to Serial Console, but nothing works.
I have a R5000 cpu, maybe there is the problem?

Thx for any hints
