[PATCH v15 00/15] qspinlock: a 4-byte queue spinlock with PV support
v14->v15:
- Incorporate PeterZ's v15 qspinlock patch and improve upon the PV
qspinlock code by dynamically allocating the hash table as well
as some other performance optimization.
- Simplified the Xen PV qspinlock code as suggested by David Vrabel
<david.vrabel at citrix.com>.
- Add benchmarking data for 3.19 kernel to compare the performance
of a spinlock heavy test
