SMAP is disabled if CPU is in non-paging mode in hardware. However KVM always uses paging mode to emulate guest non-paging mode with TDP. To emulate this behavior, SMAP needs to be manually disabled when guest switches to non-paging mode. Signed-off-by: Feng Wu <feng.wu@intel.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

The RTC tracking code tracks the cardinality of rtc_status.dest_map into rtc_status.pending_eoi. It has some WARN_ONs that trigger if pending_eoi ever becomes negative; however, these do not do anything to recover, and it bad things will happen soon after they trigger. When the next RTC interrupt is triggered, rtc_check_coalesced() will return false, but ioapic_service will find pending_eoi != 0 and do a BUG_ON. To avoid this, should pending_eoi ever be nonzero, call kvm_rtc_eoi_tracking_restore_all to recompute a correct dest_map and pending_eoi. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

QE reported that they got the BUG_ON in ioapic_service to trigger. I cannot reproduce it, but there are two reasons why this could happen. The less likely but also easiest one, is when kvm_irq_delivery_to_apic does not deliver to any APIC and returns -1. Because irqe.shorthand == 0, the kvm_for_each_vcpu loop in that function is never reached. However, you can target the similar loop in kvm_irq_delivery_to_apic_fast; just program a zero logical destination address into the IOAPIC, or an out-of-range physical destination address.

Pull kvm updates from Paolo Bonzini: "PPC and ARM do not have much going on this time. Most of the cool stuff, instead, is in s390 and (after a few releases) x86. ARM has some caching fixes and PPC has transactional memory support in guests. MIPS has some fixes, with more probably coming in 3.16 as QEMU will soon get support for MIPS KVM. For x86 there are optimizations for debug registers, which trigger on some Windows games, and other important fixes for Windows guests. We now expose to the guest Broadwell instruction set extensions and also Intel MPX. There's also a fix/workaround for OS X guests, nested virtualization features (preemption timer), and a couple kvmclock refinements. For s390, the main news is asynchronous page faults, together with improvements to IRQs (floating irqs and adapter irqs) that speed up virtio devices" * tag 'kvm-3.15-1' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (96 commits) KVM: PPC: Book3S HV: Save/restore host PMU registers that are new in POWER8 KVM: PPC: Book3S HV: Fix decrementer timeouts with non-zero TB offset KVM: PPC: Book3S HV: Don't use kvm_memslots() in real mode KVM: PPC: Book3S HV: Return ENODEV error rather than EIO KVM: PPC: Book3S: Trim top 4 bits of physical address in RTAS code KVM: PPC: Book3S HV: Add get/set_one_reg for new TM state KVM: PPC: Book3S HV: Add transactional memory support KVM: Specify byte order for KVM_EXIT_MMIO KVM: vmx: fix MPX detection KVM: PPC: Book3S HV: Fix KVM hang with CONFIG_KVM_XICS=n KVM: PPC: Book3S: Introduce hypervisor call H_GET_TCE KVM: PPC: Book3S HV: Fix incorrect userspace exit on ioeventfd write KVM: s390: clear local interrupts at cpu initial reset KVM: s390: Fix possible memory leak in SIGP functions KVM: s390: fix calculation of idle_mask array size KVM: s390: randomize sca address KVM: ioapic: reinject pending interrupts on KVM_SET_IRQCHIP KVM: Bump KVM_MAX_IRQ_ROUTES for s390 KVM: s390: irq routing for adapter interrupts.

All of them are fixes and cleanups. Specifics: - Remaining changes from upstream ACPICA release 20140214 that introduce code to automatically serialize the execution of methods creating any named objects which really cannot be executed in parallel with each other anyway (previously ACPICA attempted to address that by aborting methods upon conflict detection, but that wasn't reliable enough and led to other issues). From Bob Moore and Lv Zheng. - intel_pstate fix to use del_timer_sync() instead of del_timer() in the exit path before freeing the timer structure from Dirk Brandewie (original patch from Thomas Gleixner). - cpufreq fix related to system resume from Viresh Kumar. - Serialization of frequency transitions in cpufreq that involve PRECHANGE and POSTCHANGE notifications to avoid ordering issues resulting from race conditions. From Srivatsa S Bhat and Viresh Kumar. - Revert of an ACPI processor driver change that was based on a specific interpretation of the ACPI spec which may not be correct (the relevant part of the spec appears to be incomplete).

Pull powerpc non-virtualized cpuidle from Ben Herrenschmidt: "This is the branch I mentioned in my other pull request which contains our improved cpuidle support for the "powernv" platform (non-virtualized). It adds support for the "fast sleep" feature of the processor which provides higher power savings than our usual "nap" mode but at the cost of losing the timers while asleep, and thus exploits the new timer broadcast framework to work around that limitation.

Pull main powerpc updates from Ben Herrenschmidt: "This time around, the powerpc merges are going to be a little bit more complicated than usual. This is the main pull request with most of the work for this merge window. I will describe it a bit more further down. There is some additional cpuidle driver work, however I haven't included it in this tree as it depends on some work in tip/timer-core which Thomas accidentally forgot to put in a topic branch. Since I didn't want to carry all of that tip timer stuff in powerpc -next, I setup a separate branch on top of Thomas tree with just that cpuidle driver in it, and Stephen has been carrying that in next separately for a while now. I'll send a separate pull request for it. Additionally, two new pieces in this tree add users for a sysfs API that Tejun and Greg have been deprecating in drivers-core-next. Thankfully Greg reverted the patch that removes the old API so this merge can happen cleanly, but once merged, I will send a patch adjusting our new code to the new API so that Greg can send you the removal patch. Now as for the content of this branch, we have a lot of perf work for power8 new counters including support for our new "nest" counters (also called 24x7) under pHyp (not natively yet). We have new functionality when running under the OPAL firmware (non-virtualized or KVM host), such as access to the firmware error logs and service processor dumps, system parameters and sensors, along with a hwmon driver for the latter. There's also a bunch of bug fixes accross the board, some LE fixes, and a nice set of selftests for validating our various types of copy loops. On the Freescale side, we see mostly new chip/board revisions, some clock updates, better support for machine checks and debug exceptions, etc..." * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (70 commits) powerpc/book3s: Fix CFAR clobbering issue in machine check handler. powerpc/compat: 32-bit little endian machine name is ppcle, not ppc powerpc/le: Big endian arguments for ppc_rtas() powerpc: Use default set of netfilter modules (CONFIG_NETFILTER_ADVANCED=n) powerpc/defconfigs: Enable THP in pseries defconfig powerpc/mm: Make sure a local_irq_disable prevent a parallel THP split powerpc: Rate-limit users spamming kernel log buffer powerpc/perf: Fix handling of L3 events with bank == 1 powerpc/perf/hv_{gpci, 24x7}: Add documentation of device attributes powerpc/perf: Add kconfig option for hypervisor provided counters powerpc/perf: Add support for the hv 24x7 interface powerpc/perf: Add support for the hv gpci (get performance counter info) interface powerpc/perf: Add macros for defining event fields & formats powerpc/perf: Add a shared interface to get gpci version and capabilities powerpc/perf: Add 24x7 interface headers powerpc/perf: Add hv_gpci interface header powerpc: Add hvcalls for 24x7 and gpci (Get Performance Counter Info) sysfs: create bin_attributes under the requested group powerpc/perf: Enable BHRB access for EBB events powerpc/perf: Add BHRB constraint and IFM MMCRA handling for EBB ...

Pull x86 vdso changes from Peter Anvin: "This is the revamp of the 32-bit vdso and the associated cleanups. This adds timekeeping support to the 32-bit vdso that we already have in the 64-bit vdso. Although 32-bit x86 is legacy, it is likely to remain in the embedded space for a very long time to come. This removes the traditional COMPAT_VDSO support; the configuration variable is reused for simply removing the 32-bit vdso, which will produce correct results but obviously suffer a performance penalty. Only one beta version of glibc was affected, but that version was unfortunately included in one OpenSUSE release. This is not the end of the vdso cleanups. Stefani and Andy have agreed to continue work for the next kernel cycle; in fact Andy has already produced another set of cleanups that came too late for this cycle. An incidental, but arguably important, change is that this ensures that unused space in the VVAR page is properly zeroed. It wasn't before, and would contain whatever garbage was left in memory by BIOS or the bootloader.

We currently have three different "little environments" (boot, boot/compressed, and realmode/rm) in x86, and we are likely to soon get a fourth one (kexec/purgatory, which will have to be integrated in the kernel to support secure kexec). This is primarily a cleanup in the anticipation of the latter.

Commit 2223f6f6 "x86: Clean up dumpstack_64.c code" changed the irq_stack processing a little from what it was before. The irq_stack_end variable needed to be cleared after its first use.

Commit 2223f6f6 "x86: Clean up dumpstack_64.c code" moved the used variable to a local within the loop, but the in_exception_stack() depended on being non-volatile with the ability to change it. By always re-initializing the "used" variable to zero, it would cause the in_exception_stack() to return the same thing each time, and cause the dump_stack loop to go into an infinite loop.

Pull sound updates from Takashi Iwai: "There have been lots of changes in ALSA core, HD-audio and ASoC, also most of PCI drivers touched by conversions of printks. All these resulted in a high volume and wide ranged patch sets in this release. Many changes are fairly trivial, but also lots of nice cleanups and refactors. There are a few new drivers, most notably, the Intel Haswell and Baytrail ASoC driver. Core changes: - A bit modernization; embed the device struct into snd_card struct, so that it may be referred from the beginning. A new snd_card_new() function is introduced for that, and all drivers have been converted. - Simplification in the device management code in ALSA core; now managed by a simple priority list instead - Converted many kernel messages to use the standard dev_err() & co; this would be the pretty visible difference, especially for HD-audio. HD-audio: - Conexant codecs use the auto-parser as default now; the old static code still remains in case of regressions. Some old quirks have been rewritten with the fixups for auto-parser. - C-Media codecs also use the auto-parser as default now, too. - A device struct is assigned to each HD-audio codec, and the formerly hwdep attributes are accessible over the codec sysfs, too. hwdep attributes still remain for compatibility. - Split the PCI-specific stuff for HD-audio controller into a separate module, ane make a helper module for the generic controller driver. This is a preliminary change for supporting Tegra HDMI controller in near future, which slipped from 3.15 merge. - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more Dell laptop headset quirks - Make the HD-audio codec response a bit more robust - A few improvements on Realtek ALC282 / 283 about the pop noises - A couple of Intel HDMI fixes ASoC: - Lots of cleanups for enumerations; refactored lots of error prone original codes to use more modern APIs - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues - DPCM support for Intel Haswell and Bay Trail platforms, lots of fixes - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8 - Fixes for the simple-card DAI format DT mess - DT support for a couple more devices. - Use of the tdm_slot mapping in a few drivers Others: - Support of reset_resume callback for improved S4 in USB-audio driver; the device with boot quirks have been little tested, which we need to watch out in this development cycle - Add PM support for ICE1712 driver (finally!); it's still pretty partial support, only for M-Audio devices" * tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (610 commits) ALSA: ice1712: Add suspend support for M-Audio ICE1712-based cards ALSA: ice1712: add suspend support for ICE1712 chip ALSA: hda - Enable beep for ASUS 1015E ALSA: asihpi: fix some indenting in snd_card_asihpi_pcm_new() ALSA: hda - add headset mic detect quirks for three Dell laptops ASoC: tegra: move AC97 clock handling to the machine driver ASoC: simple-card: Handle many DAI links ASoC: simple-card: Add DT documentation for multi-DAI links ASoC: simple-card: dynamically allocate the DAI link and properties ASoC: imx-ssi: Add .xlate_tdm_slot_mask() support.

Pull regmap updates from Mark Brown: "Quite a busy release for regmap this time around, the standout changes are: - A real implementation of regmap_multi_write() and a bypassed version of it for use by drivers doing patch-like things with more open coding for surrounding startup sequences. - Support fast_io on bulk operations. - Support split device binding and map initialisation for use by devices required in early init (mainly system controllers). - Fixes for some operations on maps with strides set. - Export the value parsing operations to help generic code built on top of the API. - Support for MMIO regmaps with non-32 bit register sizes. plus a few smaller fixes" * tag 'regmap-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: (22 commits) regmap: mmio: Add regmap_mmio_regbits_check. regmap: mmio: Add support for 1/2/8 bytes wide register address. regmap: mmio: add regmap_mmio_{regsize, count}_check. regmap: cache: Don't attempt to sync non-writeable registers regmap: cache: Step by stride in default sync regmap: Fix possible sleep-in-atomic in regmap_bulk_write() regmap: Ensure regmap_register_patch() is compatible with fast_io regmap: irq: Set data pointer only on regmap_add_irq_chip success regmap: Implementation for regmap_multi_reg_write regmap: add regmap_parse_val api mfd: arizona: Use new regmap features for manual register patch regmap: Base regmap_register_patch on _regmap_multi_reg_write regmap: Add bypassed version of regmap_multi_reg_write regmap: Mark reg_defaults in regmap_multi_reg_write as const regmap: fix coccinelle warnings regmap: Check stride of register patch as we register it regmap: Clean up _regmap_update_bits() regmap: Separate regmap dev initialization regmap: Check readable regs in _regmap_read regmap: irq: Remove domain on exit ...
