https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-2.6.34.y2009-10-18T06:36:02Zsh: Fix up smp_mb__xxx() memory barriers for SH-4A SMP.2009-10-18T06:36:02ZPaul Mundt2009-10-18T06:36:02Zurn:sha1:1c8db713e21c82e14d0d1be14a09dae224472396
In the past these were simply wrapping to barrier() which was sufficient
on SH SMP platforms predating SH-4A. Unfortunately due to ll/sc semantics
an explicit synco is needed in these cases, which is sorted for us by
just switching these over to smp_mb(). smp_mb() also has the benefit of
being wrapped to barrier() in the UP and non-SH4A cases, so old behaviour
is maintained for those parts.

This ties in the new SH-2A 32-bit non-atomic bitops.

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.
Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.
