2014-01-23drivers/rtc/rtc-rx8581.c: add SMBus-only adapters supportAndreas Werner1-13/+68
Add support for SMBus-only adapters (e.g. i2c-piix4). The driver has implemented only support for I2C adapters which implement the I2C_FUNC_SMBUS_I2C_BLOCK functionality before. With this patch it is possible to load and use the RTC driver with I2C and SMBUS adapters like the rtc-ds1307 does. Tested on AMD G Series Platform (i2c-piix4 adapter driver).

2014-01-23rtc: max8907: weekday encoding fixesStephen Warren1-6/+5
The current MAX8907 driver has two issues related to weekday value handling: 1) The HW WEEKDAY register has range 0..6 rather than 1..7 as documented. Note that I validated the actual HW range by observing the HW register roll from 6->0 rather than 6->7->1 as would otherwise be expected. This matches Linux's tm_wday range of 0..6. When the CMOS RAM content is lost, the date returned from the device is 2007-01-01 00:00:00, which is a Monday. The WEEKDAY register reads 1 in this case. This matches the numbering in Linux's tm_wday field. Hence we should write Linux's tm_wday value to the register without modifying it. Hence, remove the +1/-1 calculations for WEEKDAY/tm_wday. 2) There's no need to make alarms match on the WEEKDAY register, since the other fields together uniquely define the alarm date/time. Ignoring the WEEKDAY value in the match isolates the driver from any incorrect value in the current time copy of the WEEKDAY register. Each change individually, or both together, solves an issue that I observed; "hwclock -r" would time out waiting for its alarm to fire if the CMOS RAM content had been lost, and hence the WEEKDAY register value mismatched what the driver expected it to be. "hwclock -w" would solve this by over-writing the HW default WEEKDAY register value with what the driver expected.

2014-01-23rtc: honor device tree /alias entries when assigning IDsStephen Warren1-4/+20
Assign RTC device IDs based on device tree /aliases entries if present, falling back to the existing numbering scheme if there is no /aliases entry (which includes when the system isn't booted using DT), or there is a numbering conflict. This is useful in systems with multiple RTC devices, to ensure that the best RTC device is selected as /dev/rtc0, which provides the overall system time. For example, Tegra has an on-SoC RTC that is not battery backed, typically coupled with an off-SoC RTC that is battery backed. Only the latter is useful for populating the system time, yet the former is useful e.g. for wakeup timing, since the time is not lost when the system is sleeps.

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip Pull Xen updates from Konrad Rzeszutek Wilk: "Two major features that Xen community is excited about: The first is event channel scalability by David Vrabel - we switch over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO queue with priorities. This lets us be able to handle more events, have lower latency, and better scalability. Good stuff. The other is PVH by Mukesh Rathor. In short, PV is a mode where the kernel lets the hypervisor program page-tables, segments, etc. With EPT/NPT capabilities in current processors, the overhead of doing this in an HVM (Hardware Virtual Machine) container is much lower than the hypervisor doing it for us. In short we let a PV guest run without doing page-table, segment, syscall, etc updates through the hypervisor - instead it is all done within the guest container. It is a "hybrid" PV - hence the 'PVH' name - a PV guest within an HVM container. The major benefits are less code to deal with - for example we only use one function from the the pv_mmu_ops (which has 39 function calls); faster performance for syscall (no context switches into the hypervisor); less traps on various operations; etc. It is still being baked - the ABI is not yet set in stone. But it is pretty awesome and we are excited about it. Lastly, there are some changes to ARM code - you should get a simple conflict which has been resolved in #linux-next. In short, this pull has awesome features. Features: - FIFO event channels. Key advantages: support for over 100,000 events (2^17), 16 different event priorities, improved fairness in event latency through the use of FIFOs. - Xen PVH support. "It’s a fully PV kernel mode, running with paravirtualized disk and network, paravirtualized interrupts and timers, no emulated devices of any kind (and thus no qemu), no BIOS or legacy boot — but instead of requiring PV MMU, it uses the HVM hardware extensions to virtualize the pagetables, as well as system calls and other privileged operations." (from "The Paravirtualization Spectrum, Part 2: From poles to a spectrum") Bug-fixes: - Fixes in balloon driver (refactor and make it work under ARM) - Allow xenfb to be used in HVM guests. - Allow xen_platform_pci=0 to work properly. - Refactors in event channels" * tag 'stable/for-linus-3.14-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: (52 commits) xen/pvh: Set X86_CR0_WP and others in CR0 (v2) MAINTAINERS: add git repository for Xen xen/pvh: Use 'depend' instead of 'select'. xen: delete new instances of __cpuinit usage xen/fb: allow xenfb initialization for hvm guests xen/evtchn_fifo: fix error return code in evtchn_fifo_setup() xen-platform: fix error return code in platform_pci_init() xen/pvh: remove duplicated include from enlighten.c xen/pvh: Fix compile issues with xen_pvh_domain() xen: Use dev_is_pci() to check whether it is pci device xen/grant-table: Force to use v1 of grants. xen/pvh: Support ParaVirtualized Hardware extensions (v3). xen/pvh: Piggyback on PVHVM XenBus. xen/pvh: Piggyback on PVHVM for grant driver (v4) xen/grant: Implement an grant frame array struct (v3). xen/grant-table: Refactor gnttab_init xen/grants: Remove gnttab_max_grant_frames dependency on gnttab_init. xen/pvh: Piggyback on PVHVM for event channels (v2) xen/pvh: Update E820 to work with PVH (v2) xen/pvh: Secondary VCPU bringup (non-bootup CPUs) ...

2014-01-21dm log userspace: allow mark requests to piggyback on flush requestsDongmao Zhang1-47/+159
In the cluster evironment, cluster write has poor performance because userspace_flush() has to contact a userspace program (cmirrord) for clear/mark/flush requests. But both mark and flush requests require cmirrord to communicate the message to all the cluster nodes for each flush call. This behaviour is really slow. To address this we now merge mark and flush requests together to reduce the kernel-userspace-kernel time. We allow a new directive, "integrated_flush" that can be used to instruct the kernel log code to combine flush and mark requests when directed by userspace. If not directed by userspace (due to an older version of the userspace code perhaps), the kernel will function as it did previously - preserving backwards compatibility. Additionally, flush requests are performed lazily when only clear requests exist.
