KVM/ARM updates for 4.9-rc2 - Handle faults generated by the page table walker as being writes - Map the BSS at EL2
-
由 Marc Zyngier 提交于
When used with a compiler that doesn't implement "asm goto" (such as the AArch64 port of GCC 4.8), jump labels generate a memory access to find out about the value of the key (instead of just patching the code). The key itself is likely to be stored in the BSS. This is perfectly fine, except that we don't map the BSS at HYP, leading to an exploding kernel at the first access. The obvious fix is simply to map the BSS there (which should have been done a long while ago, but hey...).

由 Will Deacon 提交于
The WnR bit in the HSR/ESR_EL2 indicates whether a data abort was generated by a read or a write instruction. For stage 2 data aborts generated by a stage 1 translation table walk (i.e. the actual page table access faults at EL2), the WnR bit therefore reports whether the instruction generating the walk was a load or a store, *not* whether the page table walker was reading or writing the entry. For page tables marked as read-only at stage 2 (e.g. due to KSM merging them with the tables from another guest), this could result in livelock, where a page table walk generated by a load instruction attempts to set the access flag in the stage 1 descriptor, but fails to trigger CoW in the host since only a read fault is reported. This patch modifies the arm64 kvm_vcpu_dabt_iswrite function to take into account stage 2 faults in stage 1 walks. Since DBM cannot be disabled at EL2 for CPUs that implement it, we assume that these faults are always causes by writes, avoiding the livelock situation at the expense of occasional, spurious CoWs. We could, in theory, do a bit better by checking the guest TCR configuration and inspecting the page table to see why the PTE faulted. However, I doubt this is measurable in practice, and the threat of livelock is real.

由 Rich Felker 提交于
At the hardware level, the J-Core PIT is integrated with the interrupt controller, but it is represented as its own device and has an independent programming interface. It provides a 12-bit countdown timer, which is not presently used, and a periodic timer. The interval length for the latter is programmable via a 32-bit throttle register whose units are determined by a bus-period register. The periodic timer is used to implement both periodic and oneshot clock event modes; in oneshot mode the interrupt handler simply disables the timer as soon as it fires. Despite its device tree node representing an interrupt for the PIT, the actual irq generated is programmable, not hard-wired. The driver is responsible for programming the PIT to generate the hardware irq number that the DT assigns to it. On SMP configurations, J-Core provides cpu-local instances of the PIT; no broadcast timer is needed. This driver supports the creation of the necessary per-cpu clock_event_device instances. A nanosecond-resolution clocksource is provided using the J-Core "RTC" registers, which give a 64-bit seconds count and 32-bit nanoseconds that wrap every second. The driver converts these to a full-range 32-bit nanoseconds count.

由 Christian Borntraeger 提交于
Usually a validity intercept is a programming error of the host because of invalid entries in the state description. We can get a validity intercept if the mode of the runtime instrumentation control block is wrong. As the host does not know which modes are valid, this can be used by userspace to trigger a WARN. Instead of printing a WARN let's return an error to userspace as this can only happen if userspace provides a malformed initial value (e.g. on migration). The kernel should never warn on bogus input. Instead let's log it into the s390 debug feature. While at it, let's return -EINVAL for all validity intercepts as this will trigger an error in QEMU like error: kvm run failed Invalid argument PSW=mask 0404c00180000000 addr 000000000063c226 cc 00 R00=000000000000004f R01=0000000000000004 R02=0000000000760005 R03=000000007fe0a000 R04=000000000064ba2a R05=000000049db73dd0 R06=000000000082c4b0 R07=0000000000000041 R08=0000000000000002 R09=000003e0804042a8 R10=0000000496152c42 R11=000000007fe0afb0 [...] This will avoid an endless loop of validity intercepts.

Pull arm64 fixes from Will Deacon: "Most of these are CC'd for stable, but there are a few fixing issues introduced during the recent merge window too. There's also a fix for the xgene PMU driver, but it seemed daft to send as a separate pull request, so I've included it here with the rest of the fixes. - Fix ACPI boot due to recent broken NUMA changes - Fix remote enabling of CPU features requiring PSTATE bit manipulation - Add address range check when emulating user cache maintenance - Fix LL/SC loops that allow compiler to introduce memory accesses - Fix recently added write_sysreg_s macro - Ensure MDCR_EL2 is initialised on qemu targets without a PMU - Avoid kaslr breakage due to MODVERSIONs and DYNAMIC_FTRACE - Correctly drive recent ld when building relocatable Image - Remove junk IS_ERR check from xgene PMU driver added during merge window - pr_cont fixes after core changes in the merge window" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: remove pr_cont abuse from mem_init arm64: fix show_regs fallout from KERN_CONT changes arm64: kernel: force ET_DYN ELF type for CONFIG_RELOCATABLE=y arm64: suspend: Reconfigure PSTATE after resume from idle arm64: mm: Set PSTATE.PAN from the cpu_enable_pan() call arm64: cpufeature: Schedule enable() calls instead of calling them via IPI arm64: Cortex-A53 errata workaround: check for kernel addresses arm64: percpu: rewrite ll/sc loops in assembly arm64: swp emulation: bound LL/SC retries before rescheduling arm64: sysreg: Fix use of XZR in write_sysreg_s arm64: kaslr: keep modules close to the kernel when DYNAMIC_FTRACE=y arm64: kernel: Init MDCR_EL2 even in the absence of a PMU perf: xgene: Remove bogus IS_ERR() check arm64: kernel: numa: fix ACPI boot cpu numa node mapping arm64: kaslr: fix breakage with CONFIG_MODVERSIONS=y

Pull MMC fixes from Ulf Hansson: "Here are some mmc fixes intended for v4.9 rc2. This time I have also included a few changes for a memstick driver which has a corresponding mmc driver. They use the same USB device as parent, hence both needs to play nice with runtime PM, which they didn't. MMC core: - Update MAINTAINERS as the mmc tree moved to kernel.org - A few fixes for HS400es mode - A few other minor fixes MMC host: - sdhci: Fix an issue when dealing with stop commands - sdhci-pci: Fix a bus power failure issue - sdhci-esdhc-imx: Correct two register accesses - sdhci-of-arasan: Fix the 1.8V I/O signal switch behaviour - rtsx_usb_sdmmc: Fix runtime PM issues Other: (Because of no maintainer) - memstick: rtsx_usb_ms: Fix runtime PM issues" * tag 'mmc-v4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: MAINTAINERS: mmc: Move the mmc tree to kernel.org memstick: rtsx_usb_ms: Manage runtime PM when accessing the device memstick: rtsx_usb_ms: Runtime resume the device when polling for cards mmc: rtsx_usb_sdmmc: Handle runtime PM while changing the led mmc: rtsx_usb_sdmmc: Avoid keeping the device runtime resumed when unused mmc: sdhci: cast unsigned int to unsigned long long to avoid unexpeted error mmc: sdhci-esdhc-imx: Correct two register accesses mmc: sdhci-pci: Fix bus power failing to enable for some Intel controllers mmc: sdhci-pci: Let devices define their own sdhci_ops mmc: sdhci: Rename sdhci_set_power() to sdhci_set_power_noreg() mmc: sdhci: Fix SDHCI_QUIRK2_STOP_WITH_TC mmc: core: Annotate cmd_hdr as __le32 mmc: sdhci-of-arasan: add sdhci_arasan_voltage_switch for arasan, 5.1 mmc: core: changes frequency to hs_max_dtr when selecting hs400es mmc: core: switch to 1V8 or 1V2 for hs400es mode mmc: block: add missing header dependencies mmc: sdhci-of-arasan: Fix non static symbol warning

'best' is always less or equals to 'pos', so `best - pos' returns a negative value which is then getting casted to `unsigned int' and passed to __cpufreq_driver_target()->acpi_cpufreq_target() for policy->freq_table selection.
