This series includes a new u8500 hwspinlock driver from Mathieu, a core fix from Juan and several other cleanups/fixes (some of which were reported by Arnd while reviewing Mathieu's driver).
Maybe the most notable core change is the move to registering a bank of hwspinlocks in a single API call, rather than the existing approach which required drivers to register each hwspinlock separately.
That also allowed eliminating 3 per-lock struct members (dev and ops, which are now maintained per-bank, and id, which is completely removed, and instead, derived from the array index of the hwspinlock struct).
The result is ~20% code reduction in the hwspinlock drivers and a smaller memory footprint.
Juan Gutierrez (1): hwspinlock/core: use a mutex to protect the radix tree
Mathieu J. Poirier (1): hwspinlock/u8500: add hwspinlock driver
Ohad Ben-Cohen (8): hwspinlock/core: simplify Kconfig hwspinlock/core: simplify 'owner' handling hwspinlock/omap: simplify allocation scheme hwspinlock/core/omap: fix id issues on multiple hwspinlock devices hwspinlock/core: remove stubs for register/unregister hwspinlock/core: register a bank of hwspinlocks in a single API call hwspinlock/omap: omap_hwspinlock_remove should be __devexit hwspinlock: add MAINTAINERS entries
