Pull arm-soc cpuidle enablement for OMAP from Olof Johansson: "Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but didn't go in because the pull request ended up rejected. So it just got merged, and we got this staged branch that enables the coupled cpuidle code on OMAP. With a stable git workflow from the other maintainer we could have staged this earlier, but that wasn't the case so we have had to merge it late. The alternative is to hold it off until 3.7 but given that the code is well-isolated to OMAP and they are eager to see it go in, I didn't push back hard in that direction." * tag 'pm2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: OMAP4: CPUidle: Open broadcast clock-event device.

2012-08-02xen/p2m: Reserve 8MB of _brk space for P2M leafs when populating back.Konrad Rzeszutek Wilk1-0/+5
When we release pages back during bootup: Freeing 9d-100 pfn range: 99 pages freed Freeing 9cf36-9d0d2 pfn range: 412 pages freed Freeing 9f6bd-9f6bf pfn range: 2 pages freed Freeing 9f714-9f7bf pfn range: 171 pages freed Freeing 9f7e0-9f7ff pfn range: 31 pages freed Freeing 9f800-100000 pfn range: 395264 pages freed Released 395979 pages of unused memory We then try to populate those pages back. In the P2M tree however the space for those leafs must be reserved - as such we use extend_brk. We reserve 8MB of _brk space, which means we can fit over 1048576 PFNs - which is more than we should ever need. Without this, on certain compilation of the kernel we would hit: (XEN) domain_crash_sync called from entry.S (XEN) CPU: 0 (XEN) RIP: e033:[<ffffffff818aad3b>] (XEN) RFLAGS: 0000000000000206 EM: 1 CONTEXT: pv guest (XEN) rax: ffffffff81a7c000 rbx: 000000000000003d rcx: 0000000000001000 (XEN) rdx: ffffffff81a7b000 rsi: 0000000000001000 rdi: 0000000000001000 (XEN) rbp: ffffffff81801cd8 rsp: ffffffff81801c98 r8: 0000000000100000 (XEN) r9: ffffffff81a7a000 r10: 0000000000000001 r11: 0000000000000003 (XEN) r12: 0000000000000004 r13: 0000000000000004 r14: 000000000000003d (XEN) r15: 00000000000001e8 cr0: 000000008005003b cr4: 00000000000006f0 (XEN) cr3: 0000000125803000 cr2: 0000000000000000 (XEN) ds: 0000 es: 0000 fs: 0000 gs: 0000 ss: e02b cs: e033 (XEN) Guest stack trace from rsp=ffffffff81801c98: .. which is extend_brk hitting a BUG_ON.

Pull ARM DMA engine updates from Russell King: "This looks scary at first glance, but what it is is: - a rework of the sa11x0 DMA engine driver merged during the previous cycle, to extract a common set of helper functions for DMA engine implementations. - conversion of amba-pl08x.c to use these helper functions. - addition of OMAP DMA engine driver (using these helper functions), and conversion of some of the OMAP DMA users to use DMA engine. Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."

2012-08-01KVM: x86: apply kvmclock offset to guest wall clock timeBruce Rogers1-0/+4
When a guest migrates to a new host, the system time difference from the previous host is used in the updates to the kvmclock system time visible to the guest, resulting in a continuation of correct kvmclock based guest timekeeping. The wall clock component of the kvmclock provided time is currently not updated with this same time offset. Since the Linux guest caches the wall clock based time, this discrepency is not noticed until the guest is rebooted. After reboot the guest's time calculations are off. This patch adjusts the wall clock by the kvmclock_offset, resulting in correct guest time after a reboot.

Pull irqdomain changes from Grant Likely: "Round of refactoring and enhancements to irq_domain infrastructure. This series starts the process of simplifying irqdomain. The ultimate goal is to merge LEGACY, LINEAR and TREE mappings into a single system, but had to back off from that after some last minute bugs. Instead it mainly reorganizes the code and ensures that the reverse map gets populated when the irq is mapped instead of the first time it is looked up. Merging of the irq_domain types is deferred to v3.7 In other news, this series adds helpers for creating static mappings on a linear or tree mapping." * tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6: irqdomain: Improve diagnostics when a domain mapping fails irqdomain: eliminate slow-path revmap lookups irqdomain: Fix irq_create_direct_mapping() to test irq_domain type. irqdomain: Eliminate dedicated radix lookup functions irqdomain: Support for static IRQ mapping and association. irqdomain: Always update revmap when setting up a virq irqdomain: Split disassociating code into separate function irq_domain: correct a minor wrong comment for linear revmap irq_domain: Standardise legacy/linear domain selection irqdomain: Make ops->map hook optional irqdomain: Remove unnecessary test for IRQ_DOMAIN_MAP_LEGACY irqdomain: Simple NUMA awareness. devicetree: add helper inline for retrieving a node's full name
2012-07-31x86: OLPC: move s/r-related EC cmds to EC driverAndres Salomon2-22/+36
The new EC driver calls platform-specific suspend and resume hooks; run XO-1-specific EC commands from there, rather than deep in s/r code. If we attempt to run EC commands after the new EC driver has suspended, it is refused by the ec->suspended checks.
