2009-09-10[ARM] pxa/colibri: add UART MFP configuration for the PXA320 moduleAlex Roman
This patch configures the MFP pads for UART1, UART2, UART3 for the Toradex Colibri PXA320 module. Previously they were just not configured resulting in just the first UART working because it was the only one that was configured by the bootloader (Toradex EBOOT in our case). This patch is against vanilla 2.6.30 and has been tested with the Toradex Orchid carrier board (all three UARTs were functional).

2009-09-10[ARM] pxa: factor pxamci gpio handlingRobert Jarzmik
Several boards use always the same pattern with pxamci : request gpio, request irq for that gpio to detect MMC card insertion, request gpio for read-only mode detection, etc ... Now that pxamci provides platform_data to describe simple gpio management of the MMC external controls, use it.

2009-09-10[ARM] pxamci: add simple gpio controlsRobert Jarzmik
The MMC block needs 3 external datas to work : - is the MMC card put in "read-only mode" ? - is a MMC card inserted or removed ? - enable power towards the MMC card Several platforms provide these controls through gpios. Expand the platform_data to request and use these gpios is set up by board code.

There is currently an uncovered case for MFP configuration on PXAs which is selected by setting the PULL_SEL bit but none of the PULL{UP,DOWN}_EN bits. This case is needed to explicitly let pins float, even if the selected alternate function would default to a configuration with a pull resistor enabled.

2009-09-10KVM guest: fix bogus wallclock physical address calculationGlauber Costa
The use of __pa() to calculate the address of a C-visible symbol is wrong, and can lead to unpredictable results. See arch/x86/include/asm/page.h for details. It should be replaced with __pa_symbol(), that does the correct math here, by taking relocations into account. This ensures the correct wallclock data structure physical address is passed to the hypervisor.

2009-09-10KVM: VMX: Fix cr8 exiting control clobbering by EPTGleb Natapov
Don't call adjust_vmx_controls() two times for the same control. It restores options that were dropped earlier.

2009-09-10KVM: When switching to a vm8086 task, load segments as 16-bitAnthony Liguori
According to 16.2.5 in the SDM, eflags.vm in the tss is consulted before loading and new segments. If eflags.vm == 1, then the segments are treated as 16-bit segments. The LDTR and TR are not normally available in vm86 mode so if they happen to somehow get loaded, they need to be treated as 32-bit segments. This fixes an invalid vmentry failure in a custom OS that was happening after a task switch into vm8086 mode. Since the segments were being mistakenly treated as 32-bit, we loaded garbage state.

2009-09-10KVM: VMX: Adjust rflags if in real mode emulationAvi Kivity

2009-09-10KVM: Update cr8 intercept when APIC TPR is changed by userspaceGleb Natapov
Since on vcpu entry we do it only if apic is enabled we should do it when TPR is changed while apic is disabled. This happens when windows resets HW without setting TPR to zero. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2009-09-10KVM: SVM: handle errors in vmrun emulation path appropriatlyJoerg Roedel
