Races in ARM atomicity.h functions?

[Alon Ziv]

Hi all,

I had a look at the atomicity functions for ARM (sysdeps/arm/atomicity.h), and 
all of them look to have subtle races in a multi-threaded environment.

At least the most widely used of those (compare_and_swap) seems to be fixable, 
but I'd like to be certain I understand these functions' usage before I touch 
them...

Can anyone enlighten me?
