* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

|
|
* If a Natoma chipset is present and this is a revision 1 zr36057,
|
|
* each MJPEG buffer needs to be physically contiguous.
|
|
* (RJ: This statement is from Dave Perks' original driver,
|
|
* I could never check it because I have a zr36067)
|
|
*
|
|
* RJ: The contents grab buffers needs never be accessed in the driver.
|
|
* Therefore there is no need to allocate them with vmalloc in order
|
|
* to get a contiguous virtual memory space.
|
|
* I don't understand why many other drivers first allocate them with
|
|
* vmalloc (which uses internally also get_zeroed_page, but delivers you
|
|
* virtual addresses) and then again have to make a lot of efforts
|
|
* to get the physical address.
|
|
*
|
|
* Ben Capper:
|
|
* On big-endian architectures (such as ppc) some extra steps
|
|
* are needed. When reading and writing to the stat_com array
|
|
* and fragment buffers, the device expects to see little-
|
|
* endian values. The use of cpu_to_le32() and le32_to_cpu()
|
|
* in this function (and one or two others in zoran_device.c)
|
|
* ensure that these values are always stored in little-endian
|
|
* form, regardless of architecture. The zr36057 does Very Bad
|
|
* Things on big endian architectures if the stat_com array
|
|
* and fragment buffers are not little-endian.
