arch/i386/kernel/time-xen.c:971: fel: omdefiniering av "raw_safe_halt"
include/asm/paravirt.h:208: fel: tidigare defintion av "raw_safe_halt" var här

make[1]: *** [arch/i386/kernel/time-xen.o] Fel 1
make: *** [arch/i386/kernel] Fel 2


Reproducible: Always

Steps to Reproduce:
1. Turn on CONFIG_PARAVIRT in .config
2. Try to compile.
3. No step 3.

Actual Results:

Expected Results:  
compiled the kernel

If you turn off CONFIG_PARAVIRT, the kernel compiles fine.

Reopen with errors in English, please. Set your locales to C when reporting bugs.

[Comment 2 Harold Anderson 2007-09-02 12:52:20 UTC]

Here's the Swedish lesson for you:

"Fel" means error.
"omdefiniering av" means redefinition of
"Tidigare defintion (sic) av var här" means previous definition was here.

[Comment 3 Jakub Moc (RETIRED) 2007-09-02 12:55:46 UTC]

Well, we don't so much want Swedish lessons but rather the messages in English in future. Posting errors in random language makes searching for duplicate bugs impossible. :/

Hm, probably will be simple to fix as long as those are the only things that get redefined but I'm curious why you would turn on paravirt_ops in the first place? I don't think anything in 2.6.20 is using that infrastructure, are you patching in lguest or vmware support? Xen doesn't start using it until 2.6.23.

OK, thanks.  I did not know that.

Dropped version. Try .29 or .31 :)
