Ok, it seems that some versions of gcc/binutils have problems with the
games that paravirt introduced with the "weak" thing.
I'm not entirely surprised. That stuff was trying to be too clever by
half.
Rusty?
Sure, but this was in .21 and .22. This config is from 2.6.21.5, in
fact.
Parag, does your arch/i386/kernel/i8259.c look like this around line
384? If not, perhaps it's a mis-merge for you?
/* Overridden in paravirt.c */
void init_IRQ(void) __attribute__((weak, alias("native_init_IRQ")));
void __init native_init_IRQ(void)
{
Never mind - I was compiling using an account which was not in use for
long and I had totally forgotten that llvm gcc comes before the normal
gcc version in the $PATH on that account. Correcting the path fixes the
problem.
Sorry for the trouble.
Parag
