Hi, I'm building kvm-29 on a system that is running linux-2.6.22.1-cfs-v19. When the modules are built I get warnings about set_64bit:
CC [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/vmx-debug.o CC [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/kvm_main.o CC [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/mmu.o /home/users/chris/rpm/BUILD/kvm-29/kernel/mmu.c: In function 'set_shadow_pte': /home/users/chris/rpm/BUILD/kvm-29/kernel/mmu.c:202: warning: implicit declaration of function 'set_64bit' CC [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/x86_emulate.o CC [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/anon_inodes.o LD [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/kvm.o LD [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/kvm-intel.o LD [M] /home/users/chris/rpm/BUILD/kvm-29/kernel/kvm-amd.o Building modules, stage 2.

I've found the set_64bit in the kernel sources - it's a macro in asm-i386/cmpxchg.h. The problem is that the macro(and some realted macros and definitions are guarded by "#ifdef CONFIG_X86_CMPXCHG64". Since that isn't defined for my kernel, set_64bit is not defined either. If I comment the guarding #ifdef (and its partner #endif) kvm builds fine and everything seems to work OK.- the modules load and Damn Small Linux and FreeBSD run fine. Any advice would be much appreciated and more than happy to test patches. I'm not subscribed, so please cc me.
