2007-12-21[POWERPC] Fix for via-pmu based backlight controlBenjamin Herrenschmidt
This fixes a few issues with via-pmu based backlight control. First, it fixes a sign problem with the setup of the backlight curve since the `range' value there -can- (and will) go negative. Then, it reworks the interaction between this and the via-pmu sleep code to properly restore backlight on wakeup from sleep.

2007-12-21[POWERPC] Implement arch disable/enable irq hooks.Scott Wood
These hooks ensure that a decrementer interrupt is not pending when suspending; otherwise, problems may occur on 6xx/7xx/7xxx-based systems (except for powermacs, which use a separate suspend path). For example, with deep sleep on the 831x, a pending decrementer will cause a system freeze because the SoC thinks the decrementer interrupt would have woken the system, but the core must have interrupts disabled due to the setup required for deep sleep. Changed via-pmu.c to use the new ppc_md hooks, and made the arch_* functions call the generic_* functions unconditionally. -- paulus Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-12-19[POWERPC] powermac: Use generic suspend codeJohannes Berg
This adds platform_suspend_ops for PMU based machines, directly in the PMU driver. This allows suspending via /sys/power/state on powerbooks. The patch also replaces the PMU ioctl with a simple call to pm_suspend(PM_SUSPEND_MEM). Additionally, it cleans up some debug code.

2007-12-19[POWERPC] Fix sleep on powerbook 3400Paul Mackerras
Sleep on the powerbook 3400 has been broken since the change that made powerbook_sleep_3400 call pmac_suspend_devices(), which disables interrupts. There are a couple of loops in powerbook_sleep_3400 that depend on interrupts being enabled, and in fact it has to have interrupts enabled at the point of going to sleep since it is an interrupt from the PMU that wakes it up. This fixes it by using pmu_wait_complete() instead of a spinloop, and by explicitly enabling interrupts before putting the CPU into sleep mode (which is OK since all interrupts except the PMU interrupt have been disabled at the interrupt controller by this stage). This changes the logic so that it keeps putting the CPU into sleep mode until the completion of the interrupt transaction from the PMU that signals the end of sleep. Also, we now call pmu_unlock() before sleep so that the via_pmu_interrupt() code can process the interrupt event from the PMU properly. Now that generic code saves and restores PCI state, it is no longer necessary to do that here. Thus pbook_pci_save/restore and related functions are no longer necessary, so this removes them. Lastly, this moves the ioremap of the memory controller to init code rather than doing it on every sleep/wakeup cycle. Signed-off-by: Paul Mackerras <paulus@samba.org>

This converts the therm_pm72.c driver to use the kthread API.

2007-12-19[POWERPC] Convert adb.c to use kthread API and not spin on ADB requestsPaul Mackerras
This converts adb.c to use the kthread API. It also changes adb_request so that if the ADBREQ_SYNC flag is specified, we now sleep waiting for the request to finish using an on-stack completion rather than spinning. To implement this, we now require that if the ADBREQ_SYNC flag is set, the `done' parameter must be NULL. All of the existing callers of adb_request that pass ADBREQ_SYNC appear to be in process context and have done == NULL. Doing this allows us to get rid of an awful hack in adb_request() where we used to test whether the request was coming from the adb probe task and use a completion if it was, and otherwise spin. This also gets rid of a static request block that was used if the req parameter to adb_request was NULL. None of the callers do that any more, so the static request block is no longer necessary.

2007-11-08[POWERPC] windfarm: Fix windfarm thread freezer interactionJohannes Berg
When I fixed the windfarm freezer interaction first in commit 1ed2ddf380e19dafeec2150ca709ef7f4a67cd21, an earlier patch than the one I came up with after comments was committed. This has come back to haunt us now because commit d5d8c5976d6adeddb8208c240460411e2198b393 changed the freezer to no long send signals. Fix it by removing the windfarm thread's signal logic and restoring the original try_to_freeze(). We could simply revert 1ed2ddf380e19dafeec2150ca709ef7f4a67cd21 now but I feel that the assertion that no signal is delivered to the windfarm thread needs not be there.

2007-10-11Input: adbhid - produce all CapsLock key eventsAndrew McNabb
The ADB keyboard, which is used for Apple PowerBooks, has strange behavior with regard to the capslock key. It keeps track of capslock state internally, and it sends a keycode when capslock is engaged and a keycode when capslock is disengaged. When the current adbhid driver sees that the capslock key is pressed or released, it creates both a keypress event and a keyrelease event simultaneously. This results in normal capslock behavior. While this works, it makes it impossible to remap the capslock key to be a control key. However, by translating the 0xff keycode into capslock keycodes, we can restore the missing capslock events and make it possible to remap the capslock key. With this patch, the adbhid driver will translate these 0xff keycodes into capslock keypresses and keyreleases if /sys/module/adbhid/parameters/restore_capslock_events is set to 1. Otherwise it will retain the current behavior. This option is off by default because occasionally the 0xff keycode is not a capslock event, and a mistake may require the user to tap the capslock key.

2007-09-22[POWERPC] adbhid: Enable KEY_FN key reportingAristeu Rozanski
When a Fn key is used in combination with another key in ADB keyboards it will generate a Fn event and then a second event that can be a different key than pressed (Fn + F1 for instance can generate Fn + brightness down if it's configured like that). This enables the reporting of the Fn key to the input system. As Fn is a dead key for most purposes, it's useful to report it so applications can make use of it. One example is apple_mouse (https://jake.ruivo.org/uinputd/trunk/apple_mouse/) that emulates the second and third keys using a combination of keyboard keys and the mouse button. Other applications may use the KEY_FN as a modifier as well. I've been updating and using this patch for months without problems.

Rather than using a tri-state integer for the wait flag in call_usermodehelper_exec, define a proper enum, and use that. I've preserved the integer values so that any callers I've missed should still work OK.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-07-12i2c: Fix the i2c_smbus_read_i2c_block_data() prototypeJean Delvare
Let the drivers specify how many bytes they want to read with i2c_smbus_read_i2c_block_data(). So far, the block count was hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense. Many driver authors complained about this before, and I believe it's about time to fix it. Right now, authors have to do technically stupid things, such as individual byte reads or full-fledged I2C messaging, to work around the problem. We do not want to encourage that. I even found that some bus drivers (e.g. i2c-amd8111) already implemented I2C block read the "right" way, that is, they didn't follow the old, broken standard. The fact that it was never noticed before just shows how little i2c_smbus_read_i2c_block_data() was used, which isn't that surprising given how broken its prototype was so far. There are some obvious compatiblity considerations: * This changes the i2c_smbus_read_i2c_block_data() prototype. Users outside the kernel tree will notice at compilation time, and will have to update their code. * User-space has access to i2c_smbus_xfer() directly using i2c-dev, so the changed expectations would affect tools such as i2cdump. In order to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the old numeric value. When i2c-dev receives a transaction with the old value, it can convert it to the new format on the fly. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)
