2011-05-19ARM: mx3/mx31moboard: properly allocate memory for mx3-cameraUwe Kleine-König
It's not allowed to create an alias of system RAM for DMA. So the memory used must not be allocated using dma_alloc_coherent but has to be reserved before using memblock routines. There is no need to memzero the buffer because dma_alloc_coherent zeros the memory for us.

2011-04-12ARM: mxc: Correct data alignment in headsmp.S for CONFIG_THUMB2_KERNELDave Martin
Directives such as .long and .word do not magically cause the assembler location counter to become aligned in gas. As a result, using these directives in code sections can result in misaligned data words when building a Thumb-2 kernel (CONFIG_THUMB2_KERNEL). This is a Bad Thing, since the ABI permits the compiler to assume that fundamental types of word size or above are word- aligned when accessing them from C. If the data is not really word-aligned, this can cause impaired performance and stray alignment faults in some circumstances. In general, the following rules should be applied when using data word declaration directives inside code sections: * .quad and .double: .align 3 * .long, .word, .single, .float: .align (or .align 2) * .short: No explicit alignment required, since Thumb-2 instructions are always 2 or 4 bytes in size. immediately after an instruction.

2011-04-12ARM: mxs/clock-mx28: fix up name##_set_rateUwe Kleine-König
For the lcdif clock get_rate looks as follows: read div from HW_CLKCTRL_DIS_LCDIF.DIV return clk_get_rate(clk->parent) / div with clk->parent being ref_pix_clk on my system. ref_pix_clk's rate depends on HW_CLKCTRL_FRAC1.PIXFRAC. The set_rate function for lcdif does: parent_rate = clk_get_rate(clk->parent); based on that calculate frac and div such that parent_rate * 18 / frac / div is near the requested rate. HW_CLKCTRL_FRAC1.PIXFRAC is updated with frac HW_CLKCTRL_DIS_LCDIF.DIV is updated with div For this calculation to be correct parent_rate needs to be initialized not with the clock rate of lcdif's parent (i.e. ref_pix) but that of its grandparent (i.e. ref_pix' parent == pll0_clk). The obvious downside of this patch is that now set_rate(lcdif) changes its parent's rate, too. Still this is better than a wrong rate.

2011-04-05inotify: fix double free/corruption of stuct userEric Paris
On an error path in inotify_init1 a normal user can trigger a double free of struct user. This is a regression introduced by a2ae4cc9a16e ("inotify: stop kernel memory leak on file creation failure"). We fix this by making sure that if a group exists the user reference is dropped when the group is cleaned up. We should not explictly drop the reference on error and also drop the reference when the group is cleaned up. The new lifetime rules are that an inotify group lives from inotify_new_group to the last fsnotify_put_group. Since the struct user and inotify_devs are directly tied to this lifetime they are only changed/updated in those two locations. We get rid of all special casing of struct user or user->inotify_devs. Signed-off-by: Eric Paris <eparis@redhat.com> Cc: stable@kernel.org (2.6.37 and up) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-04-05dm: improve block integrity supportMike Snitzer
The current block integrity (DIF/DIX) support in DM is verifying that all devices' integrity profiles match during DM device resume (which is past the point of no return). To some degree that is unavoidable (stacked DM devices force this late checking). But for most DM devices (which aren't stacking on other DM devices) the ideal time to verify all integrity profiles match is during table load. Introduce the notion of an "initialized" integrity profile: a profile that was blk_integrity_register()'d with a non-NULL 'blk_integrity' template. Add blk_integrity_is_initialized() to allow checking if a profile was initialized. Update DM integrity support to: - check all devices with _initialized_ integrity profiles match during table load; uninitialized profiles (e.g. for underlying DM device(s) of a stacked DM device) are ignored. - disallow a table load that would result in an integrity profile that conflicts with a DM device's existing (in-use) integrity profile - avoid clearing an existing integrity profile - validate all integrity profiles match during resume; but if they don't all we can do is report the mismatch (during resume we're past the point of no return) Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: Martin K.

This is a revert of 428d2e828c0a68206e5158a42451487601dc9194. This is broken in the same manner as for VGA: trying to write to an invalid address on the (currently 7-bit) i2c bus.

2011-04-05drm/i915/crt: Remove 0xa0 probe for VGAChris Wilson
This is a moral revert of 6ec3d0c0e9c0c605696e91048eebaca7b0c36695. Following the fix to reset the GMBUS controller after a NAK, we finally utilize the 0xa0 probe for a CRT connection. And discover that the code is broken. Shock. There are a number of issues, but following a key insight from Dave Airlie, that 0xA0 is an invalid address on a 7-bit bus (though not if we were to enable 10-bit addressing), and would look like the EDID port 0x50, it is possible to see where the confusion starts. In short, a write to 0xA0 is accepted by the GMBUS controller which we interpreted as meaning the existence of a connection (a slave on the other end of the wire ACKing the write). That was false. During testing with a broken GMBUS implementation, which never reset an earlier NAK, this test always reported a NAK and so we proceeded on to the next test.

2011-04-05Btrfs: fix free space cache when there are pinned extents and clusters V2Josef Bacik
I noticed a huge problem with the free space cache that was presenting as an early ENOSPC. Turns out when writing the free space cache out I forgot to take into account pinned extents and more importantly clusters. This would result in us leaking free space everytime we unmounted the filesystem and remounted it. I fix this by making sure to check and see if the current block group has a cluster and writing out any entries that are in the cluster to the cache, as well as writing any pinned extents we currently have to the cache since those will be available for us to use the next time the fs mounts. This patch also adds a check to the end of load_free_space_cache to make sure we got the right amount of free space cache, and if not make sure to clear the cache and re-cache the old fashioned way.

2011-04-05Btrfs: Fix uninitialized root flags for subvolumesLi Zefan
root_item->flags and root_item->byte_limit are not initialized when a subvolume is created. This bug is not revealed until we added readonly snapshot support - now you mount a btrfs filesystem and you may find the subvolumes in it are readonly. To work around this problem, we steal a bit from root_item->inode_item->flags, and use it to indicate if those fields have been properly initialized. When we read a tree root from disk, we check if the bit is set, and if not we'll set the flag and initialize the two fields of the root item.

2011-04-05btrfs: clear __GFP_FS flag in the space cache inodeMiao Xie
the object id of the space cache inode's key is allocated from the relative root, just like the regular file. So we can't identify space cache inode by checking the object id of the inode's key, and we have to clear __GFP_FS flag at the time we look up the space cache inode.

2011-04-05Btrfs: Fix oops for defrag with compression turned onLi Zefan
When we defrag a file, whose size can be fit into an inline extent, with compression enabled, the compress type is set to be fs_info->compress_type, which is 0 if the btrfs filesystem is mounted without compress option. This leads to oops. Reported-by: Daniel Blueman <daniel.blueman@gmail.com> Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
