2013-01-30efi: Make 'efi_enabled' a function to query EFI facilitiesMatt Fleming13-54/+79
Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

nmk_prcm_gpiocr_get_mode is only needed for debugfs output at the moment, which can be compile-time disabled. Marking the function __maybe_unused still gives us compile-time coverage, but avoids a gcc warning.

2013-01-30pinctrl: exynos: don't mark probing functions as __initArnd Bergmann1-5/+5
Functions called from a driver probe() method must not be marked __init, because they may get called after the init phase is done, when the device shows up late, or because of deferred probing. Without this patch, building exynos_defconfig results in multiple warnings like: WARNING: drivers/pinctrl/built-in.o(.text+0x51bc): Section mismatch in reference from the function exynos5440_pinctrl_probe() to the function .init.text:exynos5440_gpiolib_register() The function exynos5440_pinctrl_probe() references the function __init exynos5440_gpiolib_register(). This is often because exynos5440_pinctrl_probe lacks a __init annotation or the annotation of exynos5440_gpiolib_register is wrong.

2013-01-29x86, efi: remove attribute check from setup_efi_pciMaarten Lankhorst1-3/+0
It looks like the original commit that copied the rom contents from efi always copied the rom, and the fixup in setup_efi_pci from commit 886d751a2ea99a160 ("x86, efi: correct precedence of operators in setup_efi_pci") broke that. This resulted in macbook pro's no longer finding the rom images, and thus not being able to use the radeon card any more. The solution is to just remove the check for now, and always copy the rom if available.

2013-01-29ALSA: hda - Fix non-snoop page handlingTakashi Iwai1-14/+26
For non-snoop mode, we fiddle with the page attributes of CORB/RIRB and the position buffer, but also the ring buffers. The problem is that the current code blindly assumes that the buffer is contiguous. However, the ring buffers may be SG-buffers, thus a wrong vmapped address is passed there, leading to Oops. This patch fixes the handling for SG-buffers. Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=800701 Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-01-29powerpc: Max next_tb to prevent from replaying timer interruptTiejun Chen1-2/+7
With lazy interrupt, we always call __check_irq_replaysome with decrementers_next_tb to check if we need to replay timer interrupt. So in hotplug case we also need to set decrementers_next_tb as MAX to make sure __check_irq_replay don't replay timer interrupt when return as we expect, otherwise we'll trap here infinitely.

2013-01-29powerpc/pasemi: Fix crash on rebootSteven Rostedt1-0/+7
commit f96972f2dc "kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()" added a call to disable_nonboot_cpus() on kernel_restart(), which tries to shutdown all the CPUs except the first one. The issue with the PA Semi, is that it does not support CPU hotplug. When the call is made to __cpu_down(), it calls the notifiers CPU_DOWN_PREPARE, and then tries to take the CPU down. One of the notifiers to the CPU hotplug code, is the cpufreq. The DOWN_PREPARE will call __cpufreq_remove_dev() which calls cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O that is used by an interrupt that goes off constantly (system_reset_common, but it goes off during normal system operations too). I'm not sure exactly what this interrupt does. Running a simple function trace, you can see it goes off quite a bit: # tracer: function # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | <idle>-0 [001] 1558.859363: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.860112: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861109: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [001] 1558.861361: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861437: .pasemi_system_reset_exception <-.system_reset_exception When the region is unmapped, the system crashes with: Disabling non-boot CPUs ...
