Would prefer that changelogs be self-contained, please. Kernel
changelogs are for ever, and I doubt if that page will be there in 20
years time.
Particularly when that page must be read to learn fundamental things such as
The SMP support in certain Blackfin processors is describe as `SMP
Like' rather than just `SMP' due to the lack of hardware cache
coherency. A true SMP system would have support for cache coherency
in hardware.
On all `SMP Like' setups, cache coherency is maintained via
software mechanisms
