2013-05-09xtensa: provide custom CALLER_ADDR* implementationsMax Filippov
Definition of CALLER_ADDR* through __builtin_return_address makes compiler insert calls to __xtensa_libgcc_window_spill, which in turn makes fast_syscall_spill_registers syscall that clobbers registers when called from the kernel mode, leading to invalid opcode exceptions on return to userspace. Provide definition for CALLER_ADDR0 as MAKE_PC_FROM_RA(a0, a1) and in case CONFIG_FRAME_POINTER is enabled extract CALLER_ADDR{1-3} from stack.

2013-05-09watchdog: Fix race condition in registration codeGuenter Roeck
A race condition exists when registering the first watchdog device. Sequence of events: - watchdog_register_device calls watchdog_dev_register - watchdog_dev_register creates the watchdog misc device by calling misc_register. At that time, the matching character device (/dev/watchdog0) does not yet exist, and old_wdd is not set either. - Userspace gets an event and opens /dev/watchdog - watchdog_open is called and sets wdd = old_wdd, which is still NULL, and tries to dereference it. This causes the kernel to panic. Seen with systemd trying to open /dev/watchdog immediately after it was created.

2013-05-09KVM: VMX: fix halt emulation while emulating invalid guest sateGleb Natapov
The invalid guest state emulation loop does not check halt_request which causes 100% cpu loop while guest is in halt and in invalid state, but more serious issue is that this leaves halt_request set, so random instruction emulated by vm86 #GP exit can be interpreted as halt which causes guest hang.

2013-05-08ARM: OMAP2+: omap_device: use late_initcall_syncKevin Hilman
If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled as a module, the kernel boot hangs early as the clocks for serial port are cut while earlyprintk still uses the port. The problem is a race between the late_initcall for omap_device (which idles devices that have no drivers) and the late_initcall in kernel/printk.c which turns off the earlyconsole. Any printks that happen between this omap_device late initcall and the earlyconsole late initcall will crash when accessing the UART. The fix is to ensure the omap_device initcall happens after the earlyconsole initcall.

2013-05-08ARM: OMAP: RX-51: change probe order of touchscreen and panel SPI devicesAaro Koskinen
Commit 9fdca9df (spi: omap2-mcspi: convert to module_platform_driver) broke the SPI display/panel driver probe on RX-51/N900. The exact cause is not fully understood, but it seems to be related to the probe order. SPI communication to the panel driver (spi1.2) fails unless the touchscreen (spi1.0) has been probed/initialized before. When the omap2-mcspi driver was converted to a platform driver, it resulted in that the devices are probed immediately after the board registers them in the order they are listed in the board file. Fix the issue by moving the touchscreen before the panel in the SPI device list. The patch fixes the following failure: [ 1.260955] acx565akm spi1.2: invalid display ID [ 1.265899] panel-acx565akm display0: acx_panel_probe panel detect error [ 1.273071] omapdss CORE error: driver probe failed: -19 Tested-by: Sebastian Reichel <sre@debian.org> Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Cc: Pali Rohár <pali.rohar@gmail.com> Cc: Joni Lapilainen <joni.lapilainen@gmail.com> Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Felipe Balbi <balbi@ti.com> Cc: stable@vger.kernel.org Signed-off-by: Tony Lindgren <tony@atomide.com>

2013-05-08ARM: dts: OMAP4: Fix ethernet IRQ for OMAP4 boardsJon Hunter
Commit ff5c9059 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells property) updated the number of interrupt cells required for configuring gpios as interrupts for other devices (such as ethernet controllers). This update allowed the interrupt type (edge, level, etc) to be configured via device-tree (as described in the Documentation/devicetree/bindings/gpio/gpio-omap.txt). This broke ethernet support on the OMAP4 SDP board that defines a gpio as the ethernet IRQ because the interrupt type (level, edge, etc) was not getting configured correctly. This board use the ks8851 ethernet chip which has an active low interrupt. Fix this by defining the gpio interrupt as active-low in the device-tree binding. Please note that the OMAP4-VAR-SOM also uses the same ethernet controller and it is expected it will have the same problem. So the same fix is also applied to this board.
