* regulator: mc13783-regulator: correct the probing time.Alberto Panizzo2009-12-171-2/+2
| | | | | | | | | | | | | | | | | | | When the mc13783-regulator driver is built in kernel, probing it during the regulator subsystem initialisation result in a fault. That is because regulator subsystem is planned to be initialised very early in the boot process, before the mfd subsystem initialisation. The mc12783-regulator probing process need to access to the mc13783-core functionality to read/write mc13783 registers and so must be called after the mc13783-core driver initialisation. The way to do this is to let the kernel probe the mc13783-regulator driver when mc13783-core register his regulator subdevice.

| | | | | | | | | | | | | | | | | Since some regulators in the system may not support suspend mode configuration we need to allow some regulators to have a missing suspend mode configuration. Do this by requiring that disabled regulators are explicitly flagged and then skip over regulators that have no state specified. Try to avoid surprises by warning the if we could set the state but no configuration is provided. This also ensures that an all zeros configuration generates a warning rather than silently disabling the regulator.

* regulator: Implement WM831x BuckWise DC-DC convertor DVS supportMark Brown2009-12-172-18/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BuckWise DC-DC convertors in WM831x devices support switching to a second output voltage using the logic level on one of the device pins. This is intended to allow rapid voltage switching for uses like cpufreq, replacing the I2C or SPI write used to configure the voltage of the regulator with a much faster GPIO status change. This is implemented by keeping the DVS voltage configured as the maximum voltage permitted for the regulator. If a request is made for the maximum voltage then the GPIO is used to switch to the DVS voltage, otherwise the normal ON voltage is updated and used. This follows the idiom used by most cpufreq drivers, which drop the minimum voltage as the core frequency is dropped but use a constant maximum - raising the voltage should normally be fast, but lowering it may be slower. Configuration of the DVS MFP on the device should be done externally, for example via OTP. Support is present in the hardware for monitoring the status of the transition using a second GPIO. This is not currently implemented but platform data is provided for it - the driver currently assumes that the device will be configured to transition immediately - but platform data is provided to reduce merge issues once it is.

| * XFS: Free buffer pages array unconditionallyDave Chinner2009-12-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in xfs_free_buf() only attempts to free the b_pages array if the buffer is a page cache backed or page allocated buffer. The extra log buffer that is used when the log wraps uses pages that are allocated to a different log buffer, but it still has a b_pages array allocated when those pages are associated to with the extra buffer in xfs_buf_associate_memory. Hence we need to always attempt to free the b_pages array when tearing down a buffer, not just on buffers that are explicitly marked as page bearing buffers. This fixes a leak detected by the kernel memory leak code. Signed-off-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Alex Elder <aelder@sgi.com>

This allows merging of adjacent metadata requests but still prioritises them over bulk data. This shows a 10-15% improvement in sequential create speed of small files. Don't include the log buffers in this classification - leave them as sync types so they are issued immediately.

This patch adds a series of workarounds to allow the use of the second memory region (MEM2) as RAM by the kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the dual interrupt controller included in the "Hollywood" chipset of the Nintendo Wii video game console. This interrupt controller serves both the Broadway processor (as a cascade) and the Starlet processor, and is used to manage interrupts for the non-classic hardware.
