Dirty log query can take a long time for huge guests. Holding the mmap_sem for very long times can cause some unwanted latencies. Turns out that we do not need to hold the mmap semaphore. We hold the slots_lock for gfn->hva translation and walk the page tables with that address, so no need to look at the VMAs. KVM also holds a reference to the mm, which should prevent other things going away. During the walk we take the necessary ptl locks.

On instruction-fetch exceptions, we have to forward the PSW by any valid ilc and correctly use that ilc when injecting the irq. Injection will already take care of rewinding the PSW if we injected a nullifying program irq, so we don't need special handling prior to injection. Until now, autodetection would have guessed an ilc of 0.

Program irq injection during program irq intercepts is the last candidates that injects nullifying irqs and relies on delivery to do the right thing. As we should not rely on the icptcode during any delivery (because that value will not be migrated), let's add a flag, telling prog IRQ delivery to not rewind the PSW in case of nullifying prog IRQs.

When an instruction is to be fetched, special handling applies to secondary-space mode and access-register mode. The instruction is to be fetched from primary space. We can easily support this by selecting the right asce for translation. Access registers will never be used during translation, so don't include them in the interface. As we only want to read from the current PSW address for now, let's also hide that detail.

We have to migrate the program irq ilc and someday we will have to specify the ilc without KVM trying to autodetect the value. Let's reuse one of the spare fields in our program irq that should always be set to 0 by user space. Because we also want to make use of 0 ilcs ("not available"), we need a validity indicator. If no valid ilc is given, we try to autodetect the ilc via the current icptcode and icptstatus + parameter and store the valid ilc in the irq structure. This has a nice effect: QEMU's making use of KVM_S390_IRQ / KVM_S390_SET_IRQ_STATE / KVM_S390_GET_IRQ_STATE for migration will directly migrate the ilc without any changes. Please note that we use bit 0 as validity and bit 1,2 for the ilc, so by applying the ilc mask we directly get the ilen which is usually what we work with.

We have some confusion about ilc vs. ilen in our current code. So let's correctly use the term ilen when dealing with (ilc << 1). Program irq injection didn't take care of the correct ilc in case of irqs triggered by EXECUTE functions, let's provide one function kvm_s390_get_ilen() to take care of all that. Also, manually specifying in intercept handlers the size of the instruction (and sometimes overwriting that value for EXECUTE internally) doesn't make too much sense. So also provide the functions: - kvm_s390_retry_instr to retry the currently intercepted instruction - kvm_s390_rewind_psw to rewind the PSW without internal overwrites - kvm_s390_forward_psw to forward the PSW Reviewed-by: NChristian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: NDavid Hildenbrand <dahi@linux.vnet.ibm.com> Signed-off-by: NChristian Borntraeger <borntraeger@de.ibm.com>

As we already store the floating point registers in the vector save area in floating point register format when we don't have MACHINE_HAS_VX, we can directly expose them to user space using a new sync flag. The floating point registers will be valid when KVM_SYNC_FPRS is set. The fpc will also be valid when KVM_SYNC_FPRS is set. Either KVM_SYNC_FPRS or KVM_SYNC_VRS will be enabled, never both. Let's also change two positions where we access vrs, making the code easier to read and one comment superfluous.

So we can allow KVM_SYNC_VRS as soon as MACHINE_HAS_VX is available.

Pull power management and ACPI fixes from Rafael Wysocki: "These are: a fix for a recently introduced false-positive warnings about PM domain pointers being changed inappropriately (harmless but annoying), an MCH size workaround quirk for one more platform, a compiler warning fix (generic power domains framework), an ACPI LPSS (Intel SoCs) driver fixup and a cleanup of the ACPI CPPC core code. Specifics: - PM core fix to avoid false-positive warnings generated when the pm_domain field is cleared for a device that appears to be bound to a driver (Rafael Wysocki). - New MCH size workaround quirk for Intel Haswell-ULT (Josh Boyer). - Fix for an "unused function" compiler warning in the generic power domains framework (Ulf Hansson). - Fixup for the ACPI driver for Intel SoCs (acpi-lpss) to set the PM domain pointer of a device properly in one place that was overlooked by a recent PM core update (Andy Shevchenko). - Removal of a redundant function declaration in the ACPI CPPC core code (Timur Tabi)" * tag 'pm+acpi-4.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM: Avoid false-positive warnings in dev_pm_domain_set() PM / Domains: Silence compiler warning for an unused function ACPI / CPPC: remove redundant mbox_send_message() declaration ACPI / LPSS: set PM domain via helper setter PNP: Add Haswell-ULT to Intel MCH size workaround
