Re: some kernel headers broken in current git ?

Hi,

usually I'll wait for rc1 and test compile external module to see which are broken and what need fixing
but while I need virtualbox for some tests I test compile it on current git and it failed badly.

Maybe something is missing from x86 merge ?

Here is what I get :

...

/lib/modules/2.6.23-g4fa4d23f-dirty/build/include/asm-generic/atomic.h:23: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'atomic_long_t'

I have been unable to make heads or tails of the maze of twisty dependencies that VirtualBox wants, but the fact that it gets to line 23 of <asm-generic/atomic.h> means it has gotten past:

    21  #if BITS_PER_LONG == 64
    22
    23  typedef atomic64_t atomic_long_t;

BITS_PER_LONG was originally set in <asm/types.h>:

    39  #ifdef CONFIG_X86_32
    40  # define BITS_PER_LONG 32
    41  #else
    42  # define BITS_PER_LONG 64
    43  #endif

The most obvious reason for failure is that the symbol CONFIG_X86_32 isn't being defined where expected. From that point on everything goes to hell.

Have you done "make oldconfig && make prepare" in your kernel tree since you last updated it?
