MFD core now takes care of HWIRQ <-> VIRQ mapping, so the helper ab8500_irq_get_virq() is no longer used by ab8500 subordinate devices to obtain a Linux wide Virtual IRQ.

The ICH chips have their GPIO pins organized in 2 or 3 independent groups of 32 GPIO pins. It can happen that the ACPI BIOS wants to make use of pins in one group, preventing the OS to access these. This does not prevent the OS from accessing the other group(s). This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS wants to control GPIO 18 (group 1), while I (the OS) need to control GPIO 52 and 53 (group 2) for SMBus multiplexing. So instead of checking for ACPI resource conflict on the whole I/O range, check on a per-group basis, and consider it a success if at least one of the groups is available for the OS to use.

Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

Currently a bunch of I2C/SPI MFD drivers are using IORESOURCE_IO for register address ranges. Since this causes some confusion due to the primary use of this resource type for PCI/ISA I/O ports create a new resource type IORESOURCE_REG. Unfortunately the current resource types are specified as bitmasks and there are no free bitmasks even though they really shouldn't be used as such so we define the new type as IORESOURCE_IO | IORESOURCE_MEM. Benjamin Herrenschmidt and Russell King have both verified that none of the users in this series will have a problem with this, and no new code should be affected. This patch was written by Russell King but he found himself unable to take the patch further.

The removal of mach/io.h from most ARM platforms also set the range of valid IO ports to be empty for most platforms when previously any 32 bit integer had been valid. This makes it impossible to add IO resources as the added range is smaller than that of the root resource for IO ports. Since we're not really using IO memory at all fix this by defining our own root resource outside the normal tree and make that the parent of all IO resources. This also ensures we won't conflict with read IO ports if we ever run on a platform which happens to use them.

There are many reports (including 2 of my machines) that iTCO_wdt watchdog driver fails to be initialized in 3.5 kernel with error message like: [ 5.265175] ACPI Warning: 0x00001060-0x0000107f SystemIO conflicts with Region \_SB_.PCI0.LPCB.TCOI 1 (20120320/utaddress-251) [ 5.265192] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 5.265206] lpc_ich: Resource conflict(s) found affecting iTCO_wdt The root cause the iTCO_wdt driver in 3.4 probes the HW IO resource from LPC's PCI config space, while in 3.5 kernel it relies on lpc_ich driver for the probe, which adds a new acpi_check_resource_conflict() check, and give up the probe if there is any conflict with ACPI. Fix it by removing all the checks for iTCO_wdt to keep the same behavior as 3.4 kernel. https://bugzilla.kernel.org/show_bug.cgi?id=44991 Actually the same check could be removed for the gpio-ich in lpc_ich.c, but I'm not sure if it will cause problems.

Regulator platform data handling was mistakenly added to MFD driver. So we will see build errors if we compile MFD drivers without CONFIG_REGULATOR. This patch moves regulator platform data handling from TPS65217 MFD driver to regulator driver. This makes MFD driver independent of REGULATOR framework so build error is fixed if CONFIG_REGULATOR is not set. drivers/built-in.o: In function `tps65217_probe': tps65217.c:(.devinit.text+0x13e37): undefined reference to `of_regulator_match' This patch also fix allocation size of tps65217 platform data. Current implementation allocates a struct tps65217_board for each regulator specified in the device tree. But the structure itself provides array of regulators so one instance of it is sufficient.

Following a report of a crash during an automount expire I found that the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong. Not only is the locking wrong but the function is more complex than it needs to be. The function is meant to calculate (and dget) the next entry in the list of directories contained in the root of an autofs mount point (an autofs indirect mount to be precise). The main problem was that the d_lock of the owner of the list was not being taken when walking the list, which lead to list corruption under load. The only other lock that needs to be taken is against the next dentry candidate so it can be checked for usability.
