2007-02-20backlight: Fix external uses of backlight internal semaphoreRichard Purdie
backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

2007-02-20[MIPS] Fixup copy_from_user_inatomicRalf Baechle
From the 01408c4939479ec46c15aa7ef6e2406be50eeeca log message: The problem is that when we write to a file, the copy from userspace to pagecache is first done with preemption disabled, so if the source address is not immediately available the copy fails *and* *zeros* *the* *destination*. This is a problem because a concurrent read (which admittedly is an odd thing to do) might see zeros rather that was there before the write, or what was there after, or some mixture of the two (any of these being a reasonable thing to see). If the copy did fail, it will immediately be retried with preemption re-enabled so any transient problem with accessing the source won't cause an error. The first copying does not need to zero any uncopied bytes, and doing so causes the problem. It uses copy_from_user_atomic rather than copy_from_user so the simple expedient is to change copy_from_user_atomic to *not* zero out bytes on failure. < --- end cite --- > This patch finally implements at least a not so pretty solution by duplicating the relevant part of __copy_user.

2007-02-18[MIPS] Iomap implementation.Ralf Baechle
This implementation has support for the concept of one separate ioport address space by PCI domain.
