asm-arm/arm*/atomic.h were a copy from Linux. I don't mind if we
diverge, however the file xen/arch/arm/README.primitives needs to be
update to mention the divergence with Linux.

Julien,

AFAICT the README.LinuxPrimitives file specifies the Linux kernel
version from which the arm{32,64}/atomic.h files were imported as well
as the respective commit in the -Linux kernel- tree. I suppose that
information needn't be updated.
Could you be more specific on how I should modify that file?

To specify which helpers has been taken from Linux in those files. Until now, it was quite easy to figure out that we took all atomic_* helpers.

Regards,


Ok, will look into that.

I suppose also adding:

diff -u linux/arch/arm64/include/asm/atomic.h xen/include/asm-arm/arm64/atomic.h diff -u linux/arch/arm/include/asm/atomic.h xen/include/asm-arm/arm32/atomic.h

as it's done for the others helps?

Zuzu C.
