* backlight: update backlight status when necessaryLiu Ying2014-04-041-2/+3
| | | | | | | | | | | | | | | | | | | | | We don't have to update a backlight status every time a blanking or unblanking event comes because the backlight status may have already been what we want. Another thought is that one backlight device may be shared by multiple framebuffers. We don't hope blanking one of the framebuffers may turn the backlight off for all the other framebuffers, since they are likely being active to display something. This patch makes the backlight status be updated only when the relevant backlight device's use count changes from zero to one or from one to zero.

* backlight: update bd state & fb_blank properties when necessaryLiu Ying2014-04-041-5/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | We don't have to update the state and fb_blank properties of a backlight device every time a blanking or unblanking event comes because they may have already been what we want. Another thought is that one backlight device may be shared by multiple framebuffers. The backlight driver should take the backlight device as a resource shared by all the associated framebuffers. This patch adds some logic to record each framebuffer's backlight usage to determine the backlight device use count and whether the two properties should be updated or not. To be more specific, only one unblank operation on a certain blanked framebuffer may increase the backlight device's use count by one, while one blank operation on a certain unblanked framebuffer may decrease the use count by one, because the userspace is likely to unblank an unblanked framebuffer or blank a blanked framebuffer.

* mm + fs: store shadow entries in page cacheJohannes Weiner2014-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reclaim will be leaving shadow entries in the page cache radix tree upon evicting the real page. As those pages are found from the LRU, an iput() can lead to the inode being freed concurrently. At this point, reclaim must no longer install shadow pages because the inode freeing code needs to ensure the page tree is really empty. Add an address_space flag, AS_EXITING, that the inode freeing code sets under the tree lock before doing the final truncate. Reclaim will check for this flag before installing shadow pages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimize the hashing operation in the MXS-DCP by doing two adjustments: 1) Given that the output buffer for the hash is now always correctly aligned, we can just use the buffer for the DCP DMA to store the resulting hash. We thus get rid of one copying of data. Moreover, we remove an entry from dcp_coherent_block{} and thus lower the memory footprint of the driver. 2) We map the output buffer for the hash for DMA only in case we will output the hash, not always, as it was now.

The static checker knows they are equivalent but a human being reading the code could easily be confused. I have simplified the code by removing the "must_register_misc" variable and I have removed the redundant check on "if (!old_rng)".

Then the uninitialized list head priv->alg_list will be used in function talitos_remove(). In this case we would get a call trace like the following. So move up the initialization of priv->alg_list.
