2016-03-23platform/x86: Make intel_scu_ipc explicitly non-modularPaul Gortmaker1-31/+4
The Kconfig currently controlling compilation of this code is: drivers/platform/x86/Kconfig:config INTEL_SCU_IPC drivers/platform/x86/Kconfig: bool "Intel SCU IPC Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_pci_driver() uses the same init level priority as builtin_pci_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We don't replace module.h with init.h since the file already has that. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2016-03-23intel_pmc_ipc: Avoid pending IPC1 command during legacy suspendQipeng Zha1-1/+2
During legacy suspend flow, IPC1 commands are being requested from opregion driver. But the PMC_IPC1 command will timeout as example: [ 281.444600] ipc_debug##: ipc_send_command: cmd=0x201ff, [ 281.444648] wbuf[0]=0x4ea6 [ 281.444668] wbuf[1]=0x0 [ 281.444674] wbuf[2]=0x0 [ 281.444676] wbuf[3]=0x0 [ 284.446467] pmc-ipc-plat INT34D2:00: IPC timed out, TS=0x4, CMD=0x200ff This is because before the opregion driver could send IPC1 commands, the PMC_IPC irq is already suspended. Which makes the IPC command to timeout.

2016-03-23dell-wmi: Support new hotkeys on the XPS 13 9350 (Skylake)Andy Lutomirski1-7/+64
The XPS 13 9350 sends WMI keypress events that aren't enumerated in the DMI table. Add a table listing them. To avoid breaking things that worked before, these un-enumerated hotkeys won't be used if the DMI table maps them to something else. FWIW, it appears that the DMI table may be a legacy thing and we might want to rethink how we handle events in general. As an example, a whole lot of things map to KEY_PROG3 via the DMI table. This doesn't send keypress events for any of the new events. They appear to all be handled by other means (keyboard illumination is handled automatically and rfkill is handled by intel-hid).

2016-03-23dell-wmi: Clean up hotkey table size checkAndy Lutomirski1-2/+13
Checking the table for a minimum size of 7 bytes makes no sense: any valid hotkey table has a size that's a multiple of 4. Clean this up: replace the hardcoded header length with a sizeof and change the check to ignore an empty hotkey table. The only behavior change is that a 7-byte table (which is nonsensical) will now be treated as absent instead of as valid but empty.

2016-03-23dell-wmi: Stop storing pointers to DMI tablesAndy Lutomirski1-28/+46
The dmi_walk function maps the DMI table, walks it, and unmaps it. This means that the dell_bios_hotkey_table that find_hk_type stores points to unmapped memory by the time it gets read. I've been able to trigger crashes caused by the stale pointer a couple of times, but never on a stock kernel. Fix it by generating the keymap in the dmi_walk callback instead of storing a pointer.

2016-01-24ideapad-laptop: Add Lenovo Yoga 700 to no_hw_rfkill dmi listJosh Boyer1-0/+7
Like the Yoga 900 models the Lenovo Yoga 700 does not have a hw rfkill switch, and trying to read the hw rfkill switch through the ideapad module causes it to always reported blocking breaking wifi. This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing the wifi breakage.

2016-01-24vmstat: Remove BUG_ON from vmstat_updateChristoph Lameter1-11/+1
If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent.
