2015-03-27ARM: Remove mach-msm and associated ARM architecture codeStephen Boyd58-8699/+4
The maintainers for mach-msm no longer have any plans to support or test the platforms supported by this architecture[1]. Most likely there aren't any active users of this code anyway, so let's delete it.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management and ACPI fixes from Rafael Wysocki: "These are fixes for recent regressions (ACPI resources management, suspend-to-idle), stable-candidate fixes (ACPI backlight), fixes related to the wakeup IRQ management changes made in v3.18, other fixes (suspend-to-idle, cpufreq ppc driver) and a couple of cleanups (suspend-to-idle, generic power domains, ACPI backlight). Specifics: - Fix ACPI resources management problems introduced by the recent rework of the code in question (Jiang Liu) and a build issue introduced by those changes (Joachim Nilsson). - Fix a recent suspend-to-idle regression on systems where entering idle states causes local timers to stop, prevent suspend-to-idle from crashing in restricted configurations (no cpuidle driver, cpuidle disabled etc.) and clean up the idle loop somewhat while at it (Rafael J Wysocki). - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven). - Allow the ACPI backlight driver module to be loaded if ACPI is disabled which helps the i915 driver in those configurations (stable-candidate) and change the code to help debug unusual use cases (Chris Wilson). - Wakeup IRQ management changes in v3.18 caused some drivers on the at91 platform to trigger a warning from the IRQ core related to an unexpected combination of interrupt action handler flags. However, on at91 a timer IRQ is shared with some other devices (including system wakeup ones) and that leads to the unusual combination of flags in question. To make it possible to avoid the warning introduce a new interrupt action handler flag (which can be used by drivers to indicate the special case to the core) and rework the problematic at91 drivers to use it and work as expected during system suspend/resume.

2015-03-06arm64: Don't use is_module_addr in setting page attributesLaura Abbott1-1/+4
The set_memory_* functions currently only support module addresses. The addresses are validated using is_module_addr. That function is special though and relies on internal state in the module subsystem to work properly. At the time of module initialization and calling set_memory_*, it's too early for is_module_addr to work properly so it always returns false. Rather than be subject to the whims of the module state, just bounds check against the module virtual address range.

Commit: f31a9f7c7169 ("x86/xsaves: Use xsaves/xrstors to save and restore xsave area") introduced alternative instructions for XSAVES/XRSTORS and commit: adb9d526e982 ("x86/xsaves: Add xsaves and xrstors support for booting time") added support for the XSAVES/XRSTORS instructions at boot time. Unfortunately both failed to properly protect them against faulting: The 'xstate_fault' macro will use the closest label named '1' backward and that ends up in the .altinstr_replacement section rather than in .text. This means that the kernel will never find in the __ex_table the .text address where this instruction might fault, leading to serious problems if userspace manages to trigger the fault.

After d905c5df9aef ("PPC: POWERNV: move iommu_add_device earlier"), the refcnt on the kobject backing the IOMMU group for a PCI device is elevated by each call to pci_dma_dev_setup_pSeriesLP() (via set_iommu_table_base_and_group). When we go to dlpar a multi-function PCI device out: iommu_reconfig_notifier -> iommu_free_table -> iommu_group_put BUG_ON(tbl->it_group) We trip this BUG_ON, because there are still references on the table, so it is not freed. Fix this by moving the powernv bus notifier to common code and calling it for both powernv and pseries.

2015-03-04powerpc/smp: Wait until secondaries are active & onlineMichael Ellerman1-2/+2
Anton has a busy ppc64le KVM box where guests sometimes hit the infamous "kernel BUG at kernel/smpboot.c:134!" issue during boot: BUG_ON(td->cpu != smp_processor_id()); Basically a per CPU hotplug thread scheduled on the wrong CPU. The oops output confirms it: CPU: 0 Comm: watchdog/130 The problem is that we aren't ensuring the CPU active bit is set for the secondary before allowing the master to continue on. The master unparks the secondary CPU's kthreads and the scheduler looks for a CPU to run on. It calls select_task_rq() and realises the suggested CPU is not in the cpus_allowed mask. It then ends up in select_fallback_rq(), and since the active bit isnt't set we choose some other CPU to run on. This seems to have been introduced by 6acbfb96976f "sched: Fix hotplug vs. set_cpus_allowed_ptr()", which changed from setting active before online to setting active after online. However that was in turn fixing a bug where other code assumed an active CPU was also online, so we can't just revert that fix. The simplest fix is just to spin waiting for both active & online to be set. We already have a barrier prior to set_cpu_online() (which also sets active), to ensure all other setup is completed before online & active are set.

2015-03-03KVM: MIPS: Fix trace event to save PC directlyJames Hogan1-3/+3
Currently the guest exit trace event saves the VCPU pointer to the structure, and the guest PC is retrieved by dereferencing it when the event is printed rather than directly from the trace record. This isn't safe as the printing may occur long afterwards, after the PC has changed and potentially after the VCPU has been freed. Usually this results in the same (wrong) PC being printed for multiple trace events. It also isn't portable as userland has no way to access the VCPU data structure when interpreting the trace record itself. Lets save the actual PC in the structure so that the correct value is accessible later.

2015-03-03KVM: SVM: fix interrupt injection (apic->isr_count always 0)Radim Krčmář2-8/+2
In commit b4eef9b36db4, we started to use hwapic_isr_update() != NULL instead of kvm_apic_vid_enabled(vcpu->kvm). This didn't work because SVM had it defined and "apicv" path in apic_{set,clear}_isr() does not change apic->isr_count, because it should always be 1. The initial value of apic->isr_count was based on kvm_apic_vid_enabled(vcpu->kvm), which is always 0 for SVM, so KVM could have injected interrupts when it shouldn't. Fix it by implicitly setting SVM's hwapic_isr_update to NULL and make the initial isr_count depend on hwapic_isr_update() for good measure.

2015-02-28net: smc91x: use run-time configuration on all ARM machinesArnd Bergmann8-4/+47
The smc91x driver traditionally gets configured at compile-time for whichever hardware it runs on. This no longer works on ARM as we continue to move to building all-in-one kernels. Most ARM configurations with this driver already use run-time configuration through DT or through platform_data, but a few have not been converted yet. I've checked all ARM boards that use this driver in their legacy board files, and converted the ones that were using compile-time configuration in smc91x.h to behave like the other ones and provide the interrupt polarity along with the MMIO configuration (width, stride) at platform device creation time. In particular, these combinations were previously selectable in Kconfig but in fact broken: - sa1100 assabet plus pleb - msm combined with any other armv6/v7 platform - pxa-idp combined with any non-DMA pxa variant - LogicPD PXA270 combined with any other pxa - nomadik combined with any other armv4/v5 platform, e.g. versatile.

2015-02-28x86: Init per-cpu shadow copy of CR4 on 32-bit CPUs tooSteven Rostedt1-0/+6
Commit: 1e02ce4cccdc ("x86: Store a per-cpu shadow copy of CR4") added a shadow CR4 such that reads and writes that do not modify the CR4 execute much faster than always reading the register itself. The change modified cpu_init() in common.c, so that the shadow CR4 gets initialized before anything uses it. Unfortunately, there's two cpu_init()s in common.c. There's one for 64-bit and one for 32-bit. The commit only added the shadow init to the 64-bit path, but the 32-bit path needs the init too.

2015-02-27arm64: cpuidle: add asm/proc-fns.h inclusionLorenzo Pieralisi1-0/+2
ARM64 CPUidle driver requires the cpu_do_idle function so that it can be used to enter the shallowest idle state, and it is declared in asm/proc-fns.h. The current ARM64 CPUidle driver does not include asm/proc-fns.h explicitly and it has so far relied on implicit inclusion from other header files. Owing to some header dependencies reshuffling this currently triggers build failures when CONFIG_ARM64_64K_PAGES=y: drivers/cpuidle/cpuidle-arm64.c: In function "arm64_enter_idle_state" drivers/cpuidle/cpuidle-arm64.c:42:3: error: implicit declaration of function "cpu_do_idle" [-Werror=implicit-function-declaration] cpu_do_idle(); ^ This patch adds the explicit inclusion of the asm/proc-fns.h header file in the arm64 asm/cpuidle.h header file, so that the build breakage is fixed and the required header inclusion is added to the appropriate arch back-end CPUidle header, already included by the CPUidle arm64 driver, where CPUidle arch related function declarations belong.

2015-02-27arm64: compat Fix siginfo_t -> compat_siginfo_t conversion on big endianCatalin Marinas1-3/+2
The native (64-bit) sigval_t union contains sival_int (32-bit) and sival_ptr (64-bit). When a compat application invokes a syscall that takes a sigval_t value (as part of a larger structure, e.g. compat_sys_mq_notify, compat_sys_timer_create), the compat_sigval_t union is converted to the native sigval_t with sival_int overlapping with either the least or the most significant half of sival_ptr, depending on endianness. When the corresponding signal is delivered to a compat application, on big endian the current (compat_uptr_t)sival_ptr cast always returns 0 since sival_int corresponds to the top part of sival_ptr. This patch fixes copy_siginfo_to_user32() so that sival_int is copied to the compat_siginfo_t structure.

2015-02-27arm64: Increase the swiotlb buffer size 64MBCatalin Marinas3-19/+14
With commit 3690951fc6d4 (arm64: Use swiotlb late initialisation), the swiotlb buffer size is limited to MAX_ORDER_NR_PAGES. However, there are platforms with 32-bit only devices that require bounce buffering via swiotlb. This patch changes the swiotlb initialisation to an early 64MB memblock allocation. In order to get the swiotlb buffer correctly allocated (via memblock_virt_alloc_low_nopanic), this patch also defines ARCH_LOW_ADDRESS_LIMIT to the maximum physical address capable of 32-bit DMA.

2015-02-26arm64: Fix text patching logic when using fixmapMarc Zyngier1-1/+3
Patch 2f896d586610 ("arm64: use fixmap for text patching") changed the way we patch the kernel text, using a fixmap when the kernel or modules are flagged as read only.

2015-02-26arm64: crypto: increase AES interleave to 4xArd Biesheuvel1-1/+1
This patch increases the interleave factor for parallel AES modes to 4x. This improves performance on Cortex-A57 by ~35%. This is due to the 3-cycle latency of AES instructions on the A57's relatively deep pipeline (compared to Cortex-A53 where the AES instruction latency is only 2 cycles). At the same time, disable inline expansion of the core AES functions, as the performance benefit of this feature is negligible.

It is found that the PTE can't transit from an inaccessible page (b00) to a valid page (b11) because the mask does not allow it. This happens when a big block of mmaped memory is set the PROT_NONE, then the a small piece is broken off and set to PROT_WRITE | PROT_READ cause a huge page split.
