yann@1: Subject: Compile error with glibc 2.3.2 + Linux 2.6.5 ARCH=x86_64

yann@1: 
yann@1: I am getting compiler errors when trying to compile glibc 2.3.2 using
yann@1: the kernel headers from linux 2.6.5.  The headers from linux 2.6.3 work
yann@1: fine.
yann@1: 
yann@1: I've traced the cause of the problem to a change made in
yann@1: ./include/asm-x86_64/unistd.h in the 2.6.4 release.

yann@1: including this file, which chokes the assembler with the struct

yann@1: Changing the '#ifndef __ASSEMBLY__' to '#if ((!defined __ASSEMBLY__) &&
yann@1: (defined __KERNEL__))' clears up the problem.  My patch is below.
