2011-07-20ARM: SAMSUNG: ADC Channel selectionMyungJoo Ham
In S5PV210/S5PC110/EXYNOS4, ADCMUX channel selection uses ADCMUX register, not ADCCON register. This patch corrects the behavior of SAMSUNG-ADC for such CPUs.

2011-07-20ARM: SAMSUNG: use regulator VDD for ADCMyungJoo Ham
This patch allows the Samsung ADC driver to enable VDD regulator at probe and resume and to disable at exit and suspend. In a platform where ADC's VDD regulator is not "always-on", this control is required although this patch does not provide fine-grained power control (turning on the regulator only when being accessed). However, if VDD regulator ("vdd" for the adc device) is not provided, the regulator control will not be activated because there are platforms that do not provide regulator for ADC device. arch_initcall has been modified to module_init in order to allow regulators to be available at probe.

2011-07-20ARM: EXYNOS4: Support early wakeup entering sleep modeJaecheol Lee
Since early wakeup can be handled in pm so we don't need masking interrupts of external GIC. When the early wakeup interrupt happens, PMU(Power Management Unit) ignores WFI instruction. This means that PC(Program Counter) passed without any changes. This patch can handle that case by early wakeup interrupt.

2011-07-07xen/pci: Move check for acpi_sci_override_gsi to xen_setup_acpi_sci.Konrad Rzeszutek Wilk
Previously we would check for acpi_sci_override_gsi == gsi every time a PCI device was enabled. That works during early bootup, but later on it could lead to triggering unnecessarily the acpi_gsi_to_irq(..) lookup. The reason is that acpi_sci_override_gsi was declared in __initdata and after early bootup could contain bogus values. This patch moves the check for acpi_sci_override_gsi to the site where the ACPI SCI is preset.

2011-07-07x86: Don't use the EFI reboot method by defaultMatthew Garrett
Testing suggests that at least some Lenovos and some Intels will fail to reboot via EFI, attempting to jump to an unmapped physical address. In the long run we could handle this by providing a page table with a 1:1 mapping of physical addresses, but for now it's probably just easier to assume that ACPI or legacy methods will be present and reboot via those.

2011-07-06x86, suspend: Restore MISC_ENABLE MSR in realmode wakeupKees Cook
Some BIOSes will reset the Intel MISC_ENABLE MSR (specifically the XD_DISABLE bit) when resuming from S3, which can interact poorly with ebba638ae723d8a8fc2f7abce5ec18b688b791d7. In 32bit PAE mode, this can lead to a fault when EFER is restored by the kernel wakeup routines, due to it setting the NX bit for a CPU that (thanks to the BIOS reset) now incorrectly thinks it lacks the NX feature. (64bit is not affected because it uses a common CPU bring-up that specifically handles the XD_DISABLE bit.) The need for MISC_ENABLE being restored so early is specific to the S3 resume path. Normally, MISC_ENABLE is saved in save_processor_state(), but this happens after the resume header is created, so just reproduce the logic here. (acpi_suspend_lowlevel() creates the header, calls do_suspend_lowlevel, which calls save_processor_state(), so the saved processor context isn't available during resume header creation.)

2011-07-06ARM: 6987/1: l2x0: fix disabling function to avoid deadlockWill Deacon
The l2x0_disable function attempts to writel with the l2x0_lock held. This results in deadlock when the writel contains an outer_sync call for the platform since the l2x0_lock is already held by the disable function. A further problem is that disabling the L2 without flushing it first can lead to the spin_lock operation becoming visible after the spin_unlock, causing any subsequent L2 maintenance to deadlock. This patch replaces the writel with a call to writel_relaxed in the disabling code and adds a flush before disabling in the control register, preventing livelock from occurring.
