2009-07-05Compatibility layer for hrtimer APIMauro Carvalho Chehab
From: Jean Delvare <khali@linux-fr.org> Kernels 2.6.22 to 2.6.24 (inclusive) need some compatibility quirks for the hrtimer API. For older kernels, some required functions were not exported so there's nothing we can do. This means that drivers using the hrtimer infrastructure will no longer work for kernels older than 2.6.22.

2009-06-20compat: Fix __fls for certain ARM kernelsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> __fls() has a broken definition for ARM in from v2.6.26-7260-g0c65f45 to v2.6.28-rc6-187-g94fc733. We can fix this by just undef'ing __fls before the compat define. This will let us replace the broken one with our working one. For those kernels where the compat code is triggered and __fls works, we replace the working one with our (identical) working version, which is not a problem.

From: Trent Piepho <xyzzy@speakeasy.org> __fls() was added for generic code in 2.6.29, existed for just 64-bit arches since 2.6.26 (v2.6.25-5228-g56a6b1e), and was x86-64 only before then.

2009-03-03compat: rename struct delayed_work to work_struct on pre-2.6.20Trent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> In v2.6.19-rc6-118-g52bad64 struct work_struct was changed to be only for non-delayed work and struct delayed_work was created for delayed work. Instead of putting ifdefs in the drivers, we use compat.h to rename delayed_work to work_struct on pre-2.6.20 kernels. This will only be a problem if some driver decides to create identifiers named both work_struct and delayed_work in the same scope. There is one driver that has something named work_struct and none with anything named delayed_work, so I don't think will be a problem for as long as this compat code sticks around.

2009-01-09backport commit 5f820f648c92a5ecc771a96b3c29aa6e90013bbaMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> Author: Tejun Heo <htejun@gmail.com> poll: allow f_op->poll to sleep f_op->poll is the only vfs operation which is not allowed to sleep. It's because poll and select implementation used task state to synchronize against wake ups, which doesn't have to be the case anymore as wait/wake interface can now use custom wake up functions. The non-sleep restriction can be a bit tricky because ->poll is not called from an atomic context and the result of accidentally sleeping in ->poll only shows up as temporary busy looping when the timing is right or rather wrong. This patch converts poll/select to use custom wake up function and use separate triggered variable to synchronize against wake up events. The only added overhead is an extra function call during wake up and negligible. This patch removes the one non-sleep exception from vfs locking rules and is beneficial to userland filesystem implementations like FUSE, 9p or peculiar fs like spufs as it's very difficult for those to implement non-sleeping poll method. While at it, make the following cosmetic changes to make poll.h and select.c checkpatch friendly. * s/type * symbol/type *symbol/ : three places in poll.h * remove blank line before EXPORT_SYMBOL() : two places in select.c Oleg: spotted missing barrier in poll_schedule_timeout() Davide: spotted missing write barrier in pollwake() kernel-sync: Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-20v4l2-dev: use the release callback from device instead of cdevHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Instead of relying on the cdev release callback we should rely on the release callback from the device struct. This requires that we use get_device/put_device to do proper refcounting. In order to do this safely v4l2-dev.c now sets up its own file_operations that call out to the driver's ops.

2008-11-25fix boards for kernels with algo_controlMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> changeset 4ecae6da8244 removed algo_control from i2c drivers. However, on older kernels, a dummy function to implement algo_control is required, otherwise, an OOPS is generated. This patch adds a backport for all i2c drivers that defines an i2c_algorithm, except for cafe_ccic, since OLPC hardware only works for kernels newer than 2.6.19. Some of the backported drivers would need also extra changes to work with older kernels, as specified on v4l/versions.txt. Yet, I decided to add the backport for those drivers also, since the lack of algo_control doesn't generate any compilation error, but it is enough to break the driver. So, better to all for all boards than to allow compiling a kernel backported that just generates OOPS. Priority: normal Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
