Subject[PATCH 0 of 4] Xen spinlock updates and performance measurements
Date
From
Hi Ingo,

This series has some updates to Xen's spinlock implementation,
including adding a set of performance measurements in debugfs.

The series consists of:
- correctly deal with a spinlock in an interrupt handler interrupting
another spinlock spinning on a lock. [2.6.27 bugfix]
- Add Xen debugfs support, including performance metrics for
spinlocks, multicalls and mmu operations.
- Allow interrupts to be enabled while spinning (blocking) for a lock
- Measure time spinlocks spend blocked

Thanks,
J
