2010-01-08omap2/3: ZOOM: Correcting key mapping for few keysVimal Singh
Keys: 'right arrow', 'up arrow' and 'select' were mapped wrongly. This patch corrects them. This patch also adds one missing key present in the board, currently I added it as 'unknown' key, as I am not able to find proper description for this key. One key entry (r: 7, c: 5) is present in the keymap, which is really not present in the board, removing it.

2010-01-08omap2/3: make serial_in_override() address the right uart portAlexander Shishkin
Commit f62349ee9788b1d94c55eb6c291d74a1f69bdd9e makes it possible to have some other than first uart port as ttyS0, which breaks the workaround serial_in_override() function which will try to address the first uart port (for ttyS0) and not the one that was initialized.

2010-01-08omap: gpio: Simultaneously requested rising and falling edgeCory Maccarrone
Some chips, namely any OMAP1 chips using METHOD_MPUIO, OMAP15xx and OMAP7xx, cannot be setup to respond to on-chip GPIO interrupts in both rising and falling edge directions -- they can only respond to one direction or the other, depending on how the ICR is configured. Additionally, current code forces rising edge detection if both flags are specified: if (trigger & IRQ_TYPE_EDGE_RISING) l |= 1 << gpio; else if (trigger & IRQ_TYPE_EDGE_FALLING) l &= ~(1 << gpio); else goto bad; This change implements a toggle function that will modify the ICR to flip the direction of interrupt for IRQs that are requested with both rising and falling flags. The toggle function is not called for chips and GPIOs it does not apply to through the use of a flip_mask that's added on a per-bank basis. The mask is only set for those GPIOs where a toggle is necessary. Edge detection starts out the same as above with FALLING mode first. The toggle happens on EACH interrupt; without it, we have the following sequence of actions on GPIO transition: ICR GPIO Result 0x1 0 -> 1 (rising) Interrupt 0x1 1 -> 0 (falling) No interrupt (set ICR to 0x0 manually) 0x0 0 -> 1 (rising) No interrupt 0x0 1 -> 0 (falling) Interrupt That is, with the ICR set to 1 for a gpio, only rising edge interrupts are caught, and with it set to 0, only falling edge interrupts are caught. If we add in the toggle, we get this: ICR GPIO Result 0x1 0 -> 1 (rising) Interrupt (ICR set to 0x0) 0x0 1 -> 0 (falling) Interrupt (ICR set to 0x1) 0x1 0 -> 1 ... so, both rising and falling are caught, per the request for both (IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING).

2010-01-08GFS2: Fix locking bug in renameSteven Whitehouse

2010-01-08GFS2: Ensure uptodate inode size when using O_APPENDSteven Whitehouse
The VFS reads the inode size during generic_file_aio_write() but with no locking around it. In order to get the expected result from O_APPEND opens, this patch updated the inode size before calling generic_file_aio_write() There is of course still a race here, in that there is nothing to prevent another node coming in and extending the file in the mean time. On the other hand, when used with file locking this will ensure that the expected results are obtained. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2010-01-08drm/radeon/kms: Schedule host path read cache flush through the ring V2Jerome Glisse
R300 family will hard lockup if host path read cache flush is done through MMIO to HOST_PATH_CNTL. But scheduling same flush through ring seems harmless. This patch remove the hdp_flush callback and add a flush after each fence emission which means a flush after each IB schedule. Thus we should have same behavior without the hard lockup.

Blackfin needs it own arch specific probe_kernel_read() and probe_kernel_write(). This was moved out of the kgdb code and into the arch/blackfin/maccess.c, because it is a generic kernel api. The arch specific kgdb.c for blackfin was cleaned of all functions which exist in the kgdb core that do the same thing after resolving the probe_kernel_read() and probe_kernel_write().

reiserfs_get_acl is usually not called under the reiserfs lock, as it doesn't need it. But it happens when it is called by reiserfs_acl_chmod(), which creates a dependency inversion against the private xattr inodes mutexes for the given inode. We need to call it without the reiserfs lock, especially since it's unnecessary.
