2013-06-28powerpc/eeh: Add eeh_dev to the cache during bootThadeu Lima de Souza Cascardo
commit f8f7d63fd96ead101415a1302035137a866f8998 ("powerpc/eeh: Trace eeh device from I/O cache") broke EEH on pseries for devices that were present during boot and have not been hotplugged/DLPARed. eeh_check_failure will get the eeh_dev from the cache, and will get NULL. eeh_addr_cache_build adds the addresses to the cache, but eeh_dev for the giving pci_device is not set yet. Just reordering the call to eeh_addr_cache_insert_dev works fine. The ordering is similar to the one in eeh_add_device_late.

2013-06-27Merge tag 'msm-clock-for-3.11b' of ↵Olof Johansson
git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/late From David Brown: MSM clock updates for 3.11. Per Stephen Boyd's coverletter: Resending to collect higher level maintainer acks per Olof's request. The plan is to push this patchset through MSM to the arm-soc tree. This patchset moves the existing MSM clock code and affected drivers to the common clock framework. A prerequisite of moving to the common clock framework is to use clk_prepare() and clk_enable() so the first few patches migrate drivers to that call (clk_prepare() is a no-op on MSM right now). It also removes some custom clock APIs that MSM provides and finally moves the proc_comm clock code to the common struct clk. This patch series will be used as the foundation of the MSM 8660/8960 clock code that I plan to send out after this series. * tag 'msm-clock-for-3.11b' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm: ARM: msm: Migrate to common clock framework ARM: msm: Make proc_comm clock control into a platform driver ARM: msm: Prepare clk_get() users in mach-msm for clock-pcom driver ARM: msm: Remove clock-7x30.h include file ARM: msm: Remove custom clk_set_{max,min}_rate() API ARM: msm: Remove custom clk_set_flags() API msm: iommu: Use clk_set_rate() instead of clk_set_min_rate() msm: iommu: Convert to clk_prepare/unprepare msm_sdcc: Convert to clk_prepare/unprepare usb: otg: msm: Convert to clk_prepare/unprepare msm_serial: Use devm_clk_get() and properly return errors msm_serial: Convert to clk_prepare/unprepare Acked-by: Chris Ball <cjb@laptop.org> # for msm_sdcc.c Signed-off-by: Olof Johansson <olof@lixom.net>

2013-06-27PM / Sleep: Warn about system time after resume with pm_traceShuah Khan
pm_trace uses the system's Real Time Clock (RTC) to save the magic number. The reason for this is that the RTC is the only reliably available piece of hardware during resume operations where a value can be set that will survive a reboot. Consequence is that after a resume (even if it is successful) your system clock will have a value corresponding to the magic number instead of the correct date/time! It is therefore advisable to use a program like ntp-date or rdate to reset the correct date/time from an external time source when using this trace option. There is no run-time message to warn users of the consequences of enabling pm_trace. Adding a warning message to pm_trace_store() will serve as a reminder to users to set the system date and time after resume.

2013-06-27ALSA: usb-audio: add quirks for Roland QUAD/OCTO-CAPTUREClemens Ladisch
The Roland Quad/Octo-Capture devices use some unknown vendor-specific mechanism to switch sample rates (and to manage other controls).

2013-06-27ALSA: usb-audio: claim autodetected PCM interfaces all at onceClemens Ladisch
snd_card_register() registers all devices newly added since the last call. However, the playback/capture streams are handled as one ALSA device, so the second /dev device will not be registered if the PCM streams are added in two steps. QUIRK_AUTODETECT caused the probe callback to be called once for each interface, which triggered this problem. Work around this by handling this like the composite quirk, i.e., autodetecting all other interfaces that might be used for PCM or MIDI. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-06-27acpi-cpufreq: Add new sysfs attribute freqdomain_cpusLan Tianyu
Commits fcf8058 (cpufreq: Simplify cpufreq_add_dev()) and aa77a52 (cpufreq: acpi-cpufreq: Don't set policy->related_cpus from .init()) changed the contents of the "related_cpus" sysfs attribute on systems where acpi-cpufreq is used and user space can't get the list of CPUs which are in the same hardware coordination CPU domain (provided by the ACPI AML method _PSD) via "related_cpus" any more.

2013-06-27cpufreq: make sure frequency transitions are serializedViresh Kumar
Whenever we are changing frequency of a cpu, we are calling PRECHANGE and POSTCHANGE notifiers. They must be serialized. i.e. PRECHANGE or POSTCHANGE shouldn't be called twice contiguously. This can happen due to bugs in users of __cpufreq_driver_target() or actual cpufreq drivers who are sending these notifiers. This patch adds some protection against this.

2013-06-27ACPI: implement acpi_os_get_timer() according the specMika Westerberg
ACPI Timer() opcode should return monotonically increasing clock with 100ns granularity according the ACPI 5.0 spec. Testing the current Timer() implementation with following ASL code (and an additional debug print in acpi_os_sleep() to get the sleep times dumped out to dmesg): // Test: 10ms Store(Timer, Local1) Sleep(10) Divide(Subtract(Timer, Local1), 10000,, Local1) Sleep(Local1) // Test: 200ms Store(Timer, Local1) Sleep(200) Divide(Subtract(Timer, Local1), 10000,, Local1) Sleep(Local1) // Test 1300ms Store(Timer, Local1) Sleep(1300) Divide(Subtract(Timer, Local1), 10000,, Local1) Sleep(Local1) The second sleep value is calculated using Timer(). If the implementation is good enough we should be able to get the second value pretty close to the first. However, the current Timer() gives pretty bad sleep times: [ 11.488100] ACPI: acpi_os_get_timer() TBD [ 11.492150] ACPI: Sleep(10) [ 11.502993] ACPI: Sleep(0) [ 11.506315] ACPI: Sleep(200) [ 11.706237] ACPI: Sleep(0) [ 11.709550] ACPI: Sleep(1300) [ 13.008929] ACPI: Sleep(0) Fix this with the help of ktime_get(). Once the fix is applied and run against the same ASL code we get: [ 11.486786] ACPI: Sleep(10) [ 11.499029] ACPI: Sleep(12) [ 11.512350] ACPI: Sleep(200) [ 11.712282] ACPI: Sleep(200) [ 11.912170] ACPI: Sleep(1300) [ 13.211577] ACPI: Sleep(1300) That is much more closer to the values we expected.

2013-06-27ACPI: Add CMOS RTC Operation Region handler supportLan Tianyu
On HP Folio 13-2000, the BIOS defines a CMOS RTC Operation Region and the EC's _REG methord accesses that region. Thus an appropriate address space handler must be registered for that region before the EC driver is loaded. Introduce a mechanism for adding CMOS RTC address space handlers. Register an ACPI scan handler for CMOS RTC devices such that, when a device of that kind is detected during an ACPI namespace scan, a common CMOS RTC operation region address space handler will be installed for it.

2013-06-27rbd: send snapshot context with writesJosh Durgin
Sending the right snapshot context with each write is required for snapshots to work. Due to the ordering of calls, the snapshot context is never set for any requests. This causes writes to the current version of the image to be reflected in all snapshots, which are supposed to be read-only. This happens because rbd_osd_req_format_write() sets the snapshot context based on obj_request->img_request. At this point, however, obj_request->img_request has not been set yet, to the snapshot context is set to NULL. Fix this by moving rbd_img_obj_request_add(), which sets obj_request->img_request, before the osd request formatting calls.

2013-06-27ARM: integrator: set local side PCI addresses rightLinus Walleij
This alters the local side address of the iospace to zero, non prefetchable memory local side address to 0x00000000 and prefetchable memory local side address to 0x10000000, so as to match the values actually poked in by the driver.

2013-06-27KVM: Fix RTC interrupt coalescing trackingGleb Natapov
This reverts most of the f1ed0450a5fac7067590317cbf027f566b6ccbca. After the commit kvm_apic_set_irq() no longer returns accurate information about interrupt injection status if injection is done into disabled APIC. RTC interrupt coalescing tracking relies on the information to be accurate and cannot recover if it is not. Signed-off-by: Gleb Natapov <gleb@redhat.com>
2013-06-27kvm: Add a tracepoint write_tsc_offsetYoshihiro YUNOMAE
Add a tracepoint write_tsc_offset for tracing TSC offset change. We want to merge ftrace's trace data of guest OSs and the host OS using TSC for timestamp in chronological order. We need "TSC offset" values for each guest when merge those because the TSC value on a guest is always the host TSC plus guest's TSC offset. If we get the TSC offset values, we can calculate the host TSC value for each guest events from the TSC offset and the event TSC value. The host TSC values of the guest events are used when we want to merge trace data of guests and the host in chronological order. (Note: the trace_clock of both the host and the guest must be set x86-tsc in this case) This tracepoint also records vcpu_id which can be used to merge trace data for SMP guests. A merge tool will read TSC offset for each vcpu, then the tool converts guest TSC values to host TSC values for each vcpu. TSC offset is stored in the VMCS by vmx_write_tsc_offset() or vmx_adjust_tsc_offset(). KVM executes the former function when a guest boots. The latter function is executed when kvm clock is updated. Only host can read TSC offset value from VMCS, so a host needs to output TSC offset value when TSC offset is changed. Since the TSC offset is not often changed, it could be overwritten by other frequent events while tracing. To avoid that, I recommend to use a special instance for getting this event: 1. set a instance before booting a guest # cd /sys/kernel/debug/tracing/instances # mkdir tsc_offset # cd tsc_offset # echo x86-tsc > trace_clock # echo 1 > events/kvm/kvm_write_tsc_offset/enable 2. boot a guest Signed-off-by: Yoshihiro YUNOMAE <yoshihiro.yunomae.ez@hitachi.com> Cc: Joerg Roedel <joro@8bytes.org> Cc: Marcelo Tosatti <mtosatti@redhat.com> Cc: Gleb Natapov <gleb@redhat.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.

2013-06-27KVM: MMU: Inform users of mmio generation wraparoundTakuya Yoshikawa
Without this information, users will just see unexpected performance problems and there is little chance we will get good reports from them: note that mmio generation is increased even when we just start, or stop, dirty logging for some memory slot, in which case users cannot expect all shadow pages to be zapped. printk_ratelimited() is used for this taking into account the problems that we can see the information many times when we start multiple VMs and guests can trigger this by reading ROM in a loop for example.
