2013-05-22KVM/MIPS32: Wrap calls to gfn_to_pfn() with srcu_read_lock/unlock()Sanjay Lal
- As suggested by Gleb, wrap calls to gfn_to_pfn() with srcu_read_lock/unlock(). Memory slots should be acccessed from a SRCU read section. - kvm_mips_map_page() now returns an error code to it's callers, instead of calling panic() if it cannot find a mapping for a particular gfn.

2013-05-22ARM: shmobile: marzen: Use error values in usb_power_*Simon Horman
This patch updates the marzen board code as if USB PHY isn't enabled they phy will have a value set by ERR_PTR() rather than be NULL. Without this patch a NULL pointer dereference and kernel panic occurs on initialisation of USB on marzen. This resolves a regression introduced in 3.10-rc1 by b7fa5c2aec5be083eb2719b405089703608e9bc6 ("usb: phy: return -ENXIO when PHY layer isn't enabled").

2013-05-22MIPS: Idle: Break r4k_wait into two functions and fix it.Ralf Baechle
local_irq_enable() may expand into very different code, so it rather should stay in C. Also this keeps the assembler code size constant which keeps the rollback code simple. So it's best to split r4k_wait into two parts, one C and one assembler. Finally add the local_irq_enable() to r4k_wait to ensure the WAIT instruction in __r4k_wait() will work properly.

2013-05-22ACPI / PM: Allow device power states to be used for CONFIG_PM unsetRafael J. Wysocki
Currently, drivers/acpi/device_pm.c depends on CONFIG_PM and all of the functions defined in there are replaced with static inline stubs if that option is unset. However, CONFIG_PM means, roughly, "runtime PM or suspend/hibernation support" and some of those functions are useful regardless of that. For example, they are used by the ACPI fan driver for controlling fans and acpi_device_set_power() is called during device removal. Moreover, device initialization may depend on setting device power states properly. For these reasons, make the routines manipulating ACPI device power states defined in drivers/acpi/device_pm.c available for CONFIG_PM unset too.

2013-05-21leds: leds-gpio: reserve gpio before using itTimo Teräs
This reverts commit a99d76f (leds: leds-gpio: use gpio_request_one) and commit 2d7c22f (leds: leds-gpio: set devm_gpio_request_one() flags param correctly) which was a fix of the first one. The conversion to devm_gpio_request in commit e3b1d44c (leds: leds-gpio: use devm_gpio_request_one) is not reverted. The problem is that gpio_cansleep() and gpio_get_value_cansleep() calls can crash if the gpio is not first reserved. Incidentally this same bug existed earlier and was fixed similarly in commit d95cbe61 (leds: Fix potential leds-gpio oops). But the OOPS is real. It happens when GPIOs are provided by module which is not yet loaded. So this fixes the following BUG during my ALIX boot (3.9.2-vanilla): BUG: unable to handle kernel NULL pointer dereference at 0000004c IP: [<c11287d6>] __gpio_cansleep+0xe/0x1a *pde = 00000000 Oops: 0000 [#1] SMP Modules linked in: leds_gpio(+) via_rhine mii cs5535_mfd mfd_core geode_rng rng_core geode_aes isofs nls_utf8 nls_cp437 vfat fat ata_generic pata_amd pata_cs5536 pata_acpi libata ehci_pci ehci_hcd ohci_hcd usb_storage usbcore usb_common sd_mod scsi_mod squashfs loop Pid: 881, comm: modprobe Not tainted 3.9.2 #1-Alpine EIP: 0060:[<c11287d6>] EFLAGS: 00010282 CPU: 0 EIP is at __gpio_cansleep+0xe/0x1a EAX: 00000000 EBX: cf364018 ECX: c132b8b9 EDX: 00000000 ESI: c13993a4 EDI: c1399370 EBP: cded9dbc ESP: cded9dbc DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 CR0: 8005003b CR2: 0000004c CR3: 0f0c4000 CR4: 00000090 DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 DR6: ffff0ff0 DR7: 00000400 Process modprobe (pid: 881, ti=cded8000 task=cf094aa0 task.ti=cded8000) Stack: cded9de0 d09471cb 00000000 c1399260 cf364014 00000000 c1399260 c1399254 d0949014 cded9df4 c118cd59 c1399260 d0949014 d0949014 cded9e08 c118ba47 c1399260 d0949014 c1399294 cded9e1c c118bb75 cded9e24 d0949014 00000000 Call Trace: [<d09471cb>] gpio_led_probe+0xba/0x203 [leds_gpio] [<c118cd59>] platform_drv_probe+0x26/0x48 [<c118ba47>] driver_probe_device+0x75/0x15c [<c118bb75>] __driver_attach+0x47/0x63 [<c118a727>] bus_for_each_dev+0x3c/0x66 [<c118b6f9>] driver_attach+0x14/0x16 [<c118bb2e>] ? driver_probe_device+0x15c/0x15c [<c118b3d5>] bus_add_driver+0xbd/0x1bc [<d08b4000>] ? 0xd08b3fff [<d08b4000>] ? 0xd08b3fff [<c118bffc>] driver_register+0x74/0xec [<d08b4000>] ? 0xd08b3fff [<c118c8e8>] platform_driver_register+0x38/0x3a [<d08b400d>] gpio_led_driver_init+0xd/0x1000 [leds_gpio] [<c100116c>] do_one_initcall+0x6b/0x10f [<d08b4000>] ? 0xd08b3fff [<c105e918>] load_module+0x1631/0x1907 [<c10975d6>] ? insert_vmalloc_vmlist+0x14/0x43 [<c1098d5b>] ? __vmalloc_node_range+0x13e/0x15f [<c105ec50>] sys_init_module+0x62/0x77 [<c1257888>] syscall_call+0x7/0xb EIP: [<c11287d6>] __gpio_cansleep+0xe/0x1a SS:ESP 0068:cded9dbc CR2: 000000000000004c ---[ end trace 5308fb20d2514822 ]--- Signed-off-by: Timo Teräs <timo.teras@iki.f> Cc: Sachin Kamat <sachin.kamat@linaro.org> Cc: Raphael Assenat <raph@8d.com> Cc: Trent Piepho <tpiepho@freescale.com> Cc: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Cc: Arnaud Patard <arnaud.patard@rtp-net.org> Cc: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Acked-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>

2013-05-21klist: del waiter from klist_remove_waiters before wakeup waitting processwang, biao
There is a race between klist_remove and klist_release. klist_remove uses a local var waiter saved on stack. When klist_release calls wake_up_process(waiter->process) to wake up the waiter, waiter might run immediately and reuse the stack. Then, klist_release calls list_del(&waiter->list) to change previous wait data and cause prior waiter thread corrupt. The patch fixes it against kernel 3.9.

2013-05-21ARM: smp: Drop RCU_NONIDLE usage in cpu_die()Stephen Boyd
Before f7b861b7a6d9 ("arm: Use generic idle loop") ARM would kill the CPU within the rcu idle section. Now that the rcu_idle_enter()/exit() pair have been pushed lower down in the idle loop this is no longer true and so using RCU_NONIDLE here is no longer necessary and also harmful because RCU is not actually idle at this point.

2013-05-20ARM: tegra: defconfig fixesAlexandre Courbot
The AK8975 Kconfig option was renamed during the 3.10 merge window. Adjust tegra_defconfig to enable the new name, so it's not missing useful features. Tegra DRM support used to be enabled in the default Tegra configuration, but it now depends on CONFIG_TEGRA_HOST1X which is disabled by default. Enable CONFIG_TEGRA_HOST1X so that DRM support is compiled in again.

2013-05-20ARM: nomadik: fix IRQ assignment for SMC ethernetLinus Walleij
The assignment of IRQ for the SMC91x ethernet adapter had two problems making it non-working: - It was not put into the ethernet device node. Let's do this by using the board-specific overlay, so we can make other overlays on other Nomadik boards. - The IRQ number was actually completely wrong, this was the number for NHK8815, not S8815.

2013-05-20ARM: vt8500: Add missing NULL terminator in dt_compatSrinivas Kandagatla
When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it failed to boot. The issues seems to be changing by enabling or disabling VT8550 platform. Having a quick look at dt_compat list, it seems to miss a NULL terminator, which means of_flat_dt_match will compat check will cross the boundary of dt_compat and fault at some point , which is what was happening in my case. Without this patch if we try to boot multi_v7_defconfig you might notice that some of the platforms might fault if they fall after vt8500 in machine-desc list. Other platforms which fall before vt8500 in mdesc list will not fault.
