2015-10-06acer-wmi: remove threeg and interface sysfs interfacesLee, Chun-Yi
Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and provides the threeg rfkill interface. So the sysfs interface of 3G is no longer necessary now. The 7b8aca65 patch added kernel information log to remind to user space for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch updated the interface removing time to 2014. I think the 3 years lead time is enough for user space application to use rfkill instead of sysfs interface to control 3G device. This patch removes code about threeg sysfs interface. And it also removes the unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi driver on the machine. The information is already exposed by the acer-wmi initial log.

2015-10-06MAINTAINERS: Add drivers/platform/olpc to drivers/platform/x86Darren Hart
Andy Shevchenko sent me a simple patch that's been sitting on LKML for 10 months for OLPC and asked if I'd take it via platform/drivers/x86. OLPC appears to be unmaintained per MAINTAINERS. Add it to platform/drivers/x86 (unless someone else really wants it!) Signed-off-by: Darren Hart <dvhart@linux.intel.com>
2015-10-03platform/x86: Toshiba WMI Hotkey DriverAzael Avalos
Toshiba laptops that feature WMI events for hotkeys were left unsupported by the toshiba_acpi driver, however, commit a88bc06e5aec ("toshiba_acpi: Avoid registering input device on WMI event laptops") added hardware support for such laptops, but the hotkeys are not handled there. This driver adds support for hotkey monitoring on certain Toshiba laptops that manage the hotkeys via WMI events instead of the Toshiba Configuration Interface (TCI). The toshiba_acpi driver and this one can co-exist, as this only takes care of hotkeys, while the proper takes care of hardware related stuff. Currently the driver is under the EXPERIMENTAL flag, as the keymap and the notify function are incomplete (due to lack of hardware to test).

2015-10-03sony-laptop: Fix handling sony_nc_hotkeys_decode resultAndrzej Hajda
sony_nv_hotkeys_decode can return a negative value. real_ev is a u32 variable. The check for real_ev > 0 is incorrect. Use an intermediate ret variable. The problem has been detected using proposed semantic patch scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].

2015-10-03intel_mid_powerbtn: Remove misuse of IRQF_NO_SUSPEND flagSudeep Holla
The IRQF_NO_SUSPEND flag is used to identify the interrupts that should be left enabled so as to allow them to work as expected during the suspend-resume cycle, but doesn't guarantee that it will wake the system from a suspended state, enable_irq_wake is recommended to be used for the wakeup. This patch removes the use of IRQF_NO_SUSPEND flags and uses newly introduce PM wakeup APIs dev_pm_{set,clear}_wake_irq.

2015-10-03compal-laptop: Add charge control limitRoald Frederickx
Add charge control limit to the power supply subsystem of the Compal platform driver. This apparently was present in the original driver by Cezary Jackiewicz at http://eko.one.pl/index.php?page=compal-laptop but it seems to have been overlooked. The Kconfig description is updated to reflect this addition. It now also mentions the hwmon interface that was already present.

2015-10-03toshiba_acpi: Remove unneeded u32 variables from *setup_keyboardAzael Avalos
The function toshiba_acpi_setup_keyboard currently has two u32 variables used to store the Hotkey Event Type and the result of the HCI_SYSTEM_EVENT query. This patch removes those two variables, as we already have a global variable named "hotkey_event_type" and the result of the HCI_SYSTEM_EVENT query can be checked directly from the function.

2015-10-03toshiba_acpi: Add 0x prefix to available_kbd_modes_show functionAzael Avalos
This patch adds the 0x prefix to the values printed by such function, the values are already being printed in hex, but without the prefix, causing confusion, even though the file under Documentation/ABI clearly states that hey are hex values. Simply add the 0x prefix to avoid such confusion. Signed-off-by: Azael Avalos <coproscefalo@gmail.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
2015-10-03toshiba_acpi: Change default Hotkey enabling valueAzael Avalos
The driver currently uses the hotkey enabling value of 0x09 to enable hotkey events, but windows uses a different value (0x01). All Toshiba laptops accept the following "hotkey" parameters: 0x01 - Enable hotkey and system events. 0x03 - Enable system events only. 0x09 - Enable hotkey events only. 0x0b - Disable (hotkey and system) events. This patch changes the default hotkey enabling value from 0x09 to 0x01, enabling both the hotkey and system events.

2015-10-03toshiba_acpi: Unify hotkey enabling functionsAzael Avalos
Currently the driver has two functions enabling hotkeys support, but these two functions can be merged into one. This patch merges these two functions, moving some checks to the *enable_hotkeys function, simplifying code in the process.

2015-09-25KVM: x86: fix off-by-one in reserved bits checkPaolo Bonzini
29ecd6601904 ("KVM: x86: avoid uninitialized variable warning", 2015-09-06) introduced a not-so-subtle problem, which probably escaped review because it was not part of the patch context. Before the patch, leaf was always equal to iterator.level. After, it is equal to iterator.level - 1 in the call to is_shadow_zero_bits_set, and when is_shadow_zero_bits_set does another "-1" the check on reserved bits becomes incorrect. Using "iterator.level" in the call fixes this call trace: WARNING: CPU: 2 PID: 17000 at arch/x86/kvm/mmu.c:3385 handle_mmio_page_fault.part.93+0x1a/0x20 [kvm]() Modules linked in: tun sha256_ssse3 sha256_generic drbg binfmt_misc ipv6 vfat fat fuse dm_crypt dm_mod kvm_amd kvm crc32_pclmul aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd fam15h_power amd64_edac_mod k10temp edac_core amdkfd amd_iommu_v2 radeon acpi_cpufreq [...] Call Trace: dump_stack+0x4e/0x84 warn_slowpath_common+0x95/0xe0 warn_slowpath_null+0x1a/0x20 handle_mmio_page_fault.part.93+0x1a/0x20 [kvm] tdp_page_fault+0x231/0x290 [kvm] ? emulator_pio_in_out+0x6e/0xf0 [kvm] kvm_mmu_page_fault+0x36/0x240 [kvm] ? svm_set_cr0+0x95/0xc0 [kvm_amd] pf_interception+0xde/0x1d0 [kvm_amd] handle_exit+0x181/0xa70 [kvm_amd] ? kvm_arch_vcpu_ioctl_run+0x68b/0x1730 [kvm] kvm_arch_vcpu_ioctl_run+0x6f6/0x1730 [kvm] ? kvm_arch_vcpu_ioctl_run+0x68b/0x1730 [kvm] ? preempt_count_sub+0x9b/0xf0 ? mutex_lock_killable_nested+0x26f/0x490 ? preempt_count_sub+0x9b/0xf0 kvm_vcpu_ioctl+0x358/0x710 [kvm] ? __fget+0x5/0x210 ? __fget+0x101/0x210 do_vfs_ioctl+0x2f4/0x560 ? __fget_light+0x29/0x90 SyS_ioctl+0x4c/0x90 entry_SYSCALL_64_fastpath+0x16/0x73 ---[ end trace 37901c8686d84de6 ]--- Reported-by: Borislav Petkov <bp@alien8.de> Tested-by: Borislav Petkov <bp@alien8.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-09-25KVM: svm: do not call kvm_set_cr0 from init_vmcbPaolo Bonzini
kvm_set_cr0 may want to call kvm_zap_gfn_range and thus access the memslots array (SRCU protected). Using a mini SRCU critical section is ugly, and adding it to kvm_arch_vcpu_create doesn't work because the VMX vcpu_create callback calls synchronize_srcu.

2015-09-25iscsi-target: Avoid OFMarker + IFMarker negotiationNicholas Bellinger
This patch fixes a v4.2+ regression introduced by commit c04a6091 that removed support for obsolete sync-and-steering markers usage as originally defined in RFC-3720. The regression would involve attempting to send OFMarker=No + IFMarker=No keys during opertional negotiation login phase, including when initiators did not actually propose these keys. The result for MSFT iSCSI initiators would be random junk in TCP stream after the last successful login request was been sent signaling the move to full feature phase (FFP) operation. To address this bug, go ahead and avoid negotiating these keys by default unless the initiator explicitly proposes them, but still respond to them with 'No' if they are proposed.

2015-09-25target: Make TCM_WRITE_PROTECT failure honor D_SENSE bitNicholas Bellinger
This patch changes transport_lookup_cmd_lun() to obtain se_lun->lun_ref + se_cmd->se_device rcu_dereference during TCM_WRITE_PROTECT -> CHECK_CONDITION failure status. Do this to ensure the active control D_SENSE mode page bit is being honored.

2015-09-25target: Fix target_sense_desc_format NULL pointer dereferenceNicholas Bellinger
This patch allows target_sense_desc_format() to be called without a valid se_device pointer, which can occur during an early exception ahead of transport_lookup_cmd_lun() setting up se_cmd->se_device. This addresses a v4.3-rc1 specific NULL pointer dereference regression introduced by commit 4e4937e8.
