powerpc 32-bit seems to have it:
   arch/powerpc/kernel/misc_32.S _GLOBAL 742 _GLOBAL(atomic_clear_mask)

Assuming its the "thing" you actually want, since atomic_t is always  
an int, the exact same code sequence will be fine under 64bit, I  
guess PPc64 never needed it?
Perhaps we should move it to misc.S?

Hi,

I'm currently trying to "port" a binary-only driver to Linux/PPC :  
the card manufacturer
provides MacOS X and Linux/i386 drivers, providing *some* sources  
with the Linux driver.

The plan is to use the provided sources, and to get the remaining  
symbols & code from the MacOSX
object -- Unfortunately, one of those components makes a call to  
atomic_clear_mask(), which doesn't
seem available on PPC yet.

So the question is : is there a workaround for this, and if not,  
how would you implement this call
(I have absolutely no knowledge of PPC assembly). Quickly grepping  
through kernel headers reveals it
is present for i386, arm and x86_64, but not sparc or ppc. Is there  
a reason for this ?

Simon
