Compile Error in 2.4.7-ac10

[Andrzej Krzysztofowicz <ankry@green.mif.pg.gda.pl>]

Hi,
   What is the rason of the following messages:

> gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes
>   -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common
>   -pipe  -march=i586    -c -o traps.o traps.c
> {standard input}: Assembler messages:
> {standard input}:451: Error: suffix or operands invalid for `jmp'
> {standard input}:537: Error: suffix or operands invalid for `jmp'

or others with newer binutils:

: {standard input}: Assembler messages:
: {standard input}:461: Warning: indirect jmp without `*'
: {standard input}:547: Warning: indirect jmp without `*'

?

The following one-liner fixes them generating identical binary code with
egcs-2.91.66 and binutils-2.10.91.0.4.

Similar warnings about lcall also appear and seem to be fixable the same
way.

Andrzej
