* mfd: add AB4500 driverSrinidhi Kasagar2009-12-134-0/+480
| | | | | | | | | | | | | | This adds core driver support for AB4500 mixed signal multimedia & power management chip. This connects to U8500 on the SSP (pl022) and exports read/write functions for the device to get access to this chip. This also registers the client devices and sets the parent.

| | | | | | | | | | | | | | | | | | IXP4xx CPUs can indirectly access the whole 4 GB PCI MMIO address space (using the non-prefetch registers).

* | [BKL] add 'might_sleep()' to the outermost lock takerLinus Torvalds2009-12-121-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As shown by the previous patch (6698e3472: "tty: Fix BKL taken under a spinlock bug introduced in the BKL split") the BKL removal is prone to some subtle issues, where removing the BKL in one place may in fact make a previously nested BKL call the new outer call, and then prone to nasty deadlocks with other spinlocks. In general, we should never take the BKL while we're holding a spinlock, so let's just add a "might_sleep()" to it (even though the BKL doesn't technically sleep - at least not yet), and we'll get nice warnings the next time this kind of problem happens during BKL removal.

| * | | powerpc/pseries: Track previous CPPR values to correctly EOI interruptsMark Nelson2009-12-091-5/+51

This could lead to problems if we take an interrupt with a priority of 5, but before EOIing it we get an IPI which has a priority of 4. The problem is that at the moment when we EOI the IPI we will set the CPPR to 0xFF, but it should really be set back to 5 (the previous priority). To keep track of the previous CPPR values we create the xics_cppr structure that has an array for CPPR values and an index pointing to the current priority. This can easily grow if new priorities get added in the future. This will also be useful because the partition adjunct option of upcoming machines will update the H_XIRR hcall to accept the CPPR as a parameter.

Original patch here; http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-November/078299.html This corrects the build break by moving the online_node_cpus and offline_node_cpus under the #ifdef CONFIG_ARCH_CPU_PROBE_RELEASE portions of dlpar.c. This patch also slightly modifies the online_node_cpus and offline_node_cpus routines to prepend dlpar_ to the them and make them static. These two routine are only used in the dlpar add/remove of cpus and these changes should help clarify that.
