2012-05-18Merge branch 'at91/dt' into next/dtArnd Bergmann
This should help the merge with the at91 adc driver that is currently in the staging tree. * at91/dt: ARM: at91: Add ADC driver to at91sam9260/at91sam9g20 dtsi files Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Now that the bulk of at91sam9g20-related nodes are located in at91sam9260.dtsi, we have to re-create the path to this ADC node for SoC specific parts. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2012-05-18sh64: Fix up vmalloc fault range check.Paul Mundt
With the previous attempt reverted this switches to conditionalizing the end address. Nominally VMALLOC_END, but extended for P3_ADDR_MAX in the store queue case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-18Revert "sh: Ensure fixmap and store queue space can co-exist."Paul Mundt
This reverts commit 20e7c297efeca0861adcca073a0d283da659834b. With store queues enabled the area above P4SEG has special properties from the MMU's point of view, which was causing fixmap failure. We'll have to do something else to satisfy the vmalloc range check. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-18serial: sh-sci: Fix for port types without BRI interrupts.Paul Mundt
In doing the evt2irq() + muxed vector conversion for various port types it became apparent that some of the legacy port types will presently error out due to the irq requesting logic attempting to acquire the non-existent BRI IRQ. This adds some sanity checks to the request/free path to ensure that non-existence of a source in itself is not an error. This should restore functionality for legacy PORT_SCI ports.

2012-05-18x86-64: Fix accounting in kernel_physical_mapping_init()Jan Beulich
When finding a present and acceptable 2M/1G mapping, the number of pages mapped this way shouldn't be incremented (as it was already incremented when the earlier part of the mapping was established). Instead, last_map_addr needs to be updated in this case. Further, address increments were wrong in one place each in both phys_pmd_init() and phys_pud_init() (lacking the aligning down to the respective page boundary). As we're now doing the same calculation several times, fold it into a single instance using a local variable (matching how kernel_physical_mapping_init() itself does it at the PGD level). Observed during code inspection, not because of an actual problem.

2012-05-18x86/tlb: Clean up and unify TLB_FLUSH_ALL definitionAlex Shi

2012-05-18x86/apic: Implement EIO micro-optimizationMichael S. Tsirkin
We know both register and value for eoi beforehand, so there's no need to check it and no need to do math to calculate the msr. Saves instructions/branches on each EOI when using x2apic. I looked at the objdump output to verify that the generated code looks right and actually is shorter. The real improvemements will be on the KVM guest side though, those come in a later patch.

2012-05-18regulator: ab3100: Use regulator_map_voltage_iterate()Axel Lin
regulator_map_voltage_iterate() is for drivers implementing set_voltage_sel() and list_voltage() to use it as their map_voltage() operation. In this case, regulator_map_voltage_iterate() happen to be doing the same thing as ab3100_get_best_voltage_index() function. So we can use it to replace ab3100_get_best_voltage_index() function.

2012-05-18regulator: tps65217: Convert to set_voltage_sel and map_voltageAxel Lin
Convert tps65217_pmic_ops to use set_voltage_sel and map_voltage. After this convertion, we can also use tps65217_pmic_set_voltage_sel() for set_voltage_sel callback of tps65217_pmic_ldo1_ops. Thus this patch also removes tps65217_pmic_ldo1_set_voltage_sel() function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-18regulator: Enable the ab8500 for Device TreeLee Jones
Here we setup the ab8500 regulator driver for DT. We first do this in the normal way, by providing a match structure during initialisation, but then we provide information so that whilst probing we can use existing data structures to do DT look-ups.

2012-05-18regulator: ab8500: Split up probe() into manageable piecesLee Jones
ab8500's probe() function is becoming quite large, so in the lead up to Device Tree enablement which will fork the thread of execution this patch splits it into 3 main areas; basic error checking will remain in probe(), but regulator register initialisation and regulator registration have been moved to their own functions which will be called in sequence by probe() and the DT equivalent.
