* pxa2xx_spi: fix for SPI_CS_HIGHDaniel Ribeiro2009-06-181-1/+1
| | | | | | | | | | | | Commit a7bb3909b3293d503211d7f6af8ed62c1644b686 ("spi: pxa2xx_spi: introduce chipselect GPIO to simplify the common cases") introduces chipselect GPIO, and configures the CS polarity using SPI_CS_HIGH spi->mode flag. Add SPI_CS_HIGH to the allowed modes.

* spi: move more spi_setup() functionality into coreDavid Brownell2009-06-1816-115/+57
| | | | | | | | | | | | | | | | | | | | | | Move some common spi_setup() error checks into the SPI framework from the spi_master controller drivers: - Add a new "mode_bits" field to spi_master - Use that in spi_setup to validate the spi->mode value being requested. Setting this new field is now mandatory for any controller supporting more than vanilla SPI_MODE_0. - Update all spi_master drivers to: * Initialize that field * Remove current spi_setup() checks using that value. This is a net minor code shrink.

| | | | | | | | | | | | | | | | | | Start moving some spi_setup() functionality into the SPI core from the various spi_master controller drivers: - Make that function stop being an inline; - Move two common idioms from drivers into that new function: * Default bits_per_word to 8 if that field isn't set * Issue a standardized dev_dbg() message This is a net minor source code shrink, and supports enhancments found in some follow-up patches.

* epoll: fix nested calls supportDavide Libenzi2009-06-181-9/+12
| | | | | | | | | | | | | | | | | | | | | | | This fixes a regression in 2.6.30. I unfortunately accepted a patch time ago, to drop the "current" usage from possible IRQ context, w/out proper thought over it. The patch switched to using the CPU id by bounding the nested call callback with a get_cpu()/put_cpu(). Unfortunately the ep_call_nested() function can be called with a callback that grabs sleepy locks (from own f_op->poll()), that results in epic fails. The following patch uses the proper "context" depending on the path where it is called, and on the kind of callback. This has been reported by Stefan Richter, that has also verified the patch is his previously failing environment.

It will be helpful like statistics for interrupts. This patch introduces counting the number of softirq, which will be exported in /proc/softirqs. When softirq handler consumes much CPU time, /proc/stat is like the following. $ while :; do cat /proc/stat | head -n1 ; sleep 10 ; done cpu 88 0 408 739665 583 28 2 0 0 cpu 450 0 1090 740970 594 28 1294 0 0 ^^^^ softirq In such a situation, /proc/softirqs shows us which softirq handler is invoked.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.

It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a core driver for the AB3100 mixed-signal circuit found in the ST-Ericsson U300 series platforms. This driver is a singleton proxy for all accesses to the AB3100 sub-drivers which will be merged on top of this one, RTC, regulators, battery and system power control, vibrator, LEDs, and an ALSA codec.

After more than two years it's time to remove them finally. This patch cleans up one of the remaining users. When all such patches hit mainline we can remove the defines and typedefs finally. Impact: cleanup Convert the last remaining users and remove the typedef.

Since probing can be done anytime so clocks_init will be called anytime too. So we mark clock_init() as non-init. LD drivers/mfd/built-in.o WARNING: drivers/mfd/built-in.o(.text+0x8dd9): Section mismatch in reference from the function twl4030_probe() to the function .init.text:clocks_init() The function twl4030_probe() references the function __init clocks_init(). This is often because twl4030_probe lacks a __init annotation or the annotation of clocks_init is wrong.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kmemleak allocates memory for pointer tracking and it tries to avoid using GFP_ATOMIC if the caller doesn't require it. However other gfp flags may be passed by the caller which aren't required by kmemleak. This patch filters the gfp flags so that only GFP_KERNEL | GFP_ATOMIC are used.
