2008-10-22mfd: twl4030 IRQ handling updateDavid Brownell
- Move it into a separate file; clean and streamline it - Restructure the init code for reuse during secondary dispatch - Support both levels (primary, secondary) of IRQ dispatch - Use a workqueue for irq mask/unmask and trigger configuration Code for two subchips currently share that secondary handler code. One is the power subchip; its IRQs are now handled by this core, courtesy of this patch. The other is the GPIO module, which will be supported through a later patch. There are also minor changes to the header file, mostly related to GPIO support; nothing yet in mainline cares about those. A few references to OMAP-specific symbols are disabled; when they can all be removed, the TWL4030 support ceases being OMAP-specific.

2008-10-22workqueue: introduce create_rt_workqueueHeiko Carstens
create_rt_workqueue will create a real time prioritized workqueue. This is needed for the conversion of stop_machine to a workqueue based implementation. This patch adds yet another parameter to __create_workqueue_key to tell it that we want an rt workqueue. However it looks like we rather should have something like "int type" instead of singlethread, freezable and rt.

2008-10-22core_param() for genuinely core kernel parametersRusty Russell
There are a lot of one-liner uses of __setup() in the kernel: they're cumbersome and not queryable (definitely not settable) via /sys. Yet it's ugly to simplify them to module_param(), because by default that inserts a prefix of the module name (usually filename). So, introduce a "core_param". The parameter gets no prefix, but appears in /sys/module/kernel/parameters/ (if non-zero perms arg). I thought about using the name "core", but that's more common than "kernel". And if you create a module called "kernel", you will die a horrible death. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-10-22param: Fix duplicate module prefixesRusty Russell
Instead of insisting each new module_param sysfs entry is unique, handle the case where it already exists (for builtin modules). The current code assumes that all identical prefixes are together in the section: true for normal uses, but not necessarily so if someone overrides MODULE_PARAM_PREFIX. More importantly, it's not true with the new "core_param()" code which uses "kernel" as a prefix. This simplifies the caller for the builtin case, at a slight loss of efficiency (we do the lookup every time to see if the directory exists).

2008-10-22module: check kernel param length at compile time, not runtimeRusty Russell
The kparam code tries to handle over-length parameter prefixes at runtime. Not only would I bet this has never been tested, it's not clear that truncating names is a good idea either. So let's check at compile time. We need to move the #define to moduleparam.h to do this, though. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-10-22module: simplify load_module.Rusty Russell
Linus' recent catch of stack overflow in load_module lead me to look at the code. A couple of helpers to get a section address and get objects from a section can help clean things up a little. (And in case you're wondering, the stack size also dropped from 328 to 284 bytes). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2008-10-21V4L/DVB (9331): Remove unused inode parameter from video_ioctl2Mauro Carvalho Chehab
inode is never used on video_ioctl2. Remove it and rename the function to __video_ioctl2. This allows its usage directly as a callback at fops.unlocked_ioctl. Since we still need a callback with inode to be used with fops.ioctl, this patch adds video_ioctl2() that is just a call to __video_ioctl2(). Also, this patch adds some comments about video_ioctl2 and __video_ioctl2 usage at v4l2-ioctl.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-21[PATCH] beginning of methods conversionAl Viro
To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2008-10-21powerpc/oprofile: Fix mutex locking for cell spu-oprofileCarl Love
The issue is the SPU code is not holding the kernel mutex lock while adding samples to the kernel buffer. This patch creates per SPU buffers to hold the data. Data is added to the buffers from in interrupt context. The data is periodically pushed to the kernel buffer via a new Oprofile function oprofile_put_buff(). The oprofile_put_buff() function is called via a work queue enabling the funtion to acquire the mutex lock. The existing user controls for adjusting the per CPU buffer size is used to control the size of the per SPU buffers. Similarly, overflows of the SPU buffers are reported by incrementing the per CPU buffer stats. This eliminates the need to have architecture specific controls for the per SPU buffers which is not acceptable to the OProfile user tool maintainer. The export of the oprofile add_event_entry() is removed as it is no longer needed given this patch. Note, this patch has not addressed the issue of indexing arrays by the spu number. This still needs to be fixed as the spu numbering is not guarenteed to be 0 to max_num_spus-1.

2008-10-21md: use sysfs_notify_dirent to notify changes to md/dev-xxx/stateNeilBrown
The 'state' file for a device reports, for example, when the device has failed. Changes should be reported to userspace ASAP without the possibility of blocking on low-memory. sysfs_notify does have that possibility (as it takes a mutex which can be held across a kmalloc) so use sysfs_notify_dirent instead.

2008-10-20leds: Make default trigger fields constTrent Piepho
The default_trigger fields of struct gpio_led and thus struct led_classdev are pretty much always assigned from a string literal, which means the string can't be modified. Which is fine, since there is no reason to modify the string and in fact it never is. But they should be marked const to prevent such code from being added, to prevent warnings if -Wwrite-strings is used, when assigned from a constant string other than a string literal (which produces a warning under current kernel compiler flags), and for general good coding practices.
