Service Bus - unaligned 64-bit atomic operation when running on mips

[jackesdavid]

Fix the unaligned 64-bit atomic operation in Service Bus

On non-Linux ARM, the 64-bit functions use instructions unavailable before the ARMv6k core.
On ARM, x86-32, and 32-bit MIPS,
it is the caller's responsibility to arrange for 64-bit
alignment of 64-bit words accessed atomically. The first word in a
variable or in an allocated struct, array, or slice can be relied upon to be
64-bit aligned.

@jackesdavid - thank you, this is a really interesting bug report!

But now I have a question for you - what are you doing with Service Bus + openWRT? Is this something that's public?

Hi Friend, its a project for a company, its a really interisting usage on a very low spec hardware ( a router )
