2014-09-23ARM: mm: Fix ifdef around cpu_*_do_[suspend, resume] opsBartlomiej Zolnierkiewicz
Ifdef around cpu_\name\()_do_suspend and cpu_\name\()_do_resume ops in proc-macros.S should check for CONFIG_ARM_CPU_SUSPEND and not CONFIG_PM_SLEEP. Fix it. [ Please note that cpu_v7_do_[suspend,resume] code in proc-v7.S already correctly checks for CONFIG_ARM_CPU_SUSPEND, same is true for functions for other architectures. ] This fix is needed for decoupling suspend/resume and advanced cpuidle support on Exynos platform (next patch fixes build for config with CONFIG_PM_SLEEP=n and CONFIG_ARM_EXYNOS_CPUIDLE=y). If this fix is not present then the following OOPS happens on the first attempt to go into advanced cpuidle mode (AFTR): [ 22.244143] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 22.250759] pgd = c0004000 [ 22.253445] [00000000] *pgd=00000000 [ 22.257012] Internal error: Oops: 80000007 [#1] PREEMPT SMP ARM [ 22.262906] Modules linked in: [ 22.265949] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.16.0-next-20140811-dirty #730 [ 22.273757] task: c05dce68 ti: c05d2000 task.ti: c05d2000 [ 22.279139] PC is at 0x0 [ 22.281661] LR is at __cpu_suspend_save+0x4c/0xa8 [ 22.286344] pc : [<00000000>] lr : [<c00125e0>] psr: a0000093 [ 22.286344] sp : c05d3ef4 ip : c05da414 fp : 00000001 [ 22.297799] r10: c05da414 r9 : c0609cb0 r8 : 0000000f [ 22.303008] r7 : c05da444 r6 : 00000038 r5 : ea802c00 r4 : c05d3f14 [ 22.309517] r3 : 00000000 r2 : c05d3f4c r1 : 00000038 r0 : c05d3f20 [ 22.316029] Flags: NzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment kernel [ 22.323406] Control: 10c5387d Table: 69d5404a DAC: 00000015 [ 22.329135] Process swapper/0 (pid: 0, stack limit = 0xc05d2240) [ 22.335124] Stack: (0xc05d3ef4 to 0xc05d4000) [ 22.339466] 3ee0: ea802c00 00000038 c05d3f4c [ 22.347626] 3f00: 00000000 00000007 c00123bc 00000000 c001d468 6a888000 c05d3f4c 80000000 [ 22.355785] 3f20: 00000007 c003d3a0 0000193d eaf9dde4 eaf9dde4 c02ef0c8 c000969c fffffffe [ 22.363944] 3f40: 00000000 c0037b54 eaf9dbb8 e9d1a380 00000000 c001d468 c0609cb0 00000000 [ 22.372103] 3f60: c0609cb0 c061649e 00000001 c001250c eaf9dbb8 00000001 c0609cb0 c001d618 [ 22.380262] 3f80: c001d5d0 c02ef56c 2d9d2e1e 00000005 eaf9dbb8 c02edcc4 2d9d2e1e 00000005 [ 22.388421] 3fa0: c040446c c05da4ec c040446c eaf9dbb8 c05cfbb0 c004c580 c05dce68 c05b3ae8 [ 22.396580] 3fc0: 00000000 c058bb24 ffffffff ffffffff c058b5e4 00000000 00000000 c05b3ae8 [ 22.404740] 3fe0: c0616994 c05da47c c05b3ae4 c05ddeec 4000406a 40008074 00000000 00000000 [ 22.412909] [<c00125e0>] (__cpu_suspend_save) from [<c00123bc>] (__cpu_suspend+0x5c/0x70) [ 22.421074] [<c00123bc>] (__cpu_suspend) from [<c05d3f4c>] (init_thread_union+0x1f4c/0x2000) [ 22.429479] Code: bad PC value [ 22.432518] ---[ end trace fb90ebf4217d0ad9 ]--- [ 22.437116] Kernel panic - not syncing: Attempted to kill the idle task!

This patch removes the null test on block. block is initialized at the beginning of the function to &wblock->gblock.

The following Coccinelle script is used for detecting the change: @r@ expression e,f; identifier g,y; statement S1,S2; @@ *e = &f->g <+... f->y ...+> *if (e != NULL || ...)

2014-08-16asus-wmi: backlight_init: Stop treating -ENODEV as if its not an errorHans de Goede
When bl_power support got added to asus-wmi, the error handling for it was written to ignore -ENODEV, to avoid not registering a backlight interface for models which have no bl_power control, but do have brightness control. At the same time the error handling for brightness_max was modified to do the same, this is wrong, when there is no brightness_max asus-wmi should not register a backlight interface. Note the caller of asus_wmi_backlight_init already special cases -ENODEV, and will not cause the wmi driver regristration to fail because of a -ENODEV return from asus_wmi_backlight_init. https://bugzilla.redhat.com/show_bug.cgi?id=1097436 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2014-08-16asus-wmi: Disable acpi-video backlight on desktop machinesHans de Goede
Some Asus motherboards for desktop PC-s export an acpi-video interface advertising backlight support. Test the dmi chassis-type and tell acpi-video to not register a backlight interface on desktops. https://bugzilla.redhat.com/show_bug.cgi?id=1097436 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2014-08-16ideapad-laptop: Change Lenovo Yoga 2 series rfkill handlingHans de Goede
It seems that the same problems which lead to adding an rfkill blacklist and putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13 and Lenovo Yoga 2 Pro too: https://bugzilla.redhat.com/show_bug.cgi?id=1021036 https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612 Testing has shown that the firmware rfkill settings are persistent over reboots. So blacklisting the driver is not good enough, if the wifi is blocked at the firmware level the wifi needs to be explictly unblocked through the ideapad-laptop interface. And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices with hardware kill switch reports the hardware switch state, needs to be explictly set to 1 (radio enabled / not blocked). So this patch does 3 things to get proper rfkill handling on these models: 1) Instead of blacklisting the rfkill functionality, which means that people with a firmware blocked wifi get stuck in that situation, ignore the value reported by the not present hardware rfkill switch, as this is what is causing ideapad-laptop to wrongly report all radios as hardware blocks. But do register the rfkill interfaces so that the user can soft [un]block them. 2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1 3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2 series is affected.

2014-08-16thinkpad_acpi: Update mapping for F12 hotkey on *40 models to KEY_FILEHans de Goede
The new keyboard found on the *40 models is also being sold as a standalone keyboard (with trackpoint): http://shop.lenovo.com/us/en/itemdetails/0B47189/460/60AC6A0372B14F5BA7B12F1FF88E33C7 This uses a standard HUT code for the F12 key with the 6 square boxes on it, which gets mapped to KEY_FILE by the kernel. Change the mapping done of identical laptop key done by thinkpad_acpi to also send KEY_FILE for consistency.

2014-08-16eeepc-laptop: rename _set and _get arguments in macroPaul Bolle
The _set and _get arguments to the EEEPC_CREATE_SENSOR_ATTR() macro are confusingly named: _set should be _get and vice versa. Rename these arguments.

2014-08-16fujitsu-laptop: Clear build warningsJean Delvare
When CONFIG_FUJITSU_LAPTOP_DEBUG is disabled and W=1, the fujitsu-laptop driver builds with the following warnings: drivers/platform/x86/fujitsu-laptop.c: In function "bl_update_status": drivers/platform/x86/fujitsu-laptop.c:409:8: warning: suggest braces around empty body in an "if" statement [-Wempty-body] ret); ^ drivers/platform/x86/fujitsu-laptop.c:418:8: warning: suggest braces around empty body in an "if" statement [-Wempty-body] ret); ^ Rework the debug printk helper macro to get rid of these. I verified that this change has no effect on the generated binary, both in the debug and non-debug case.
