Hi Jens,

This series is just for the patch from Dongsheng Yang, due to more
testing needed, it comes after the first wave.

Dongsheng's patch helps to improve the latency of cache space
allocation. This patch has been shipped in product more than one year
by his team. Robert Pang from Google introduces this patch has been
tested inside Google with quite extended hardware configurations. Eric
Wheeler also deploys this patch in his production for 1+ months.

So far there is no issue reported for this patch, except for a bug in
existed code and easier to be trigger by Dongsheng's patch. This is why
my first patch is composed. Another patch from me is just a code
cleanup cought my eyes during the fix.

Please consider to take them, and thank you in advance.
