* MIPS: RB532: Detect uart type, add platform devicePhil Sutter2009-01-302-1/+27
| | | | | | | | | Auto-detection works just fine, so use it instead of specifying the type manually. Also define a platform device for the uart, as suggested by David Daney. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: RB532: remove useless CF GPIO initialisationPhil Sutter2009-01-301-6/+0
| | | | | | | | | | | | As the pata-rb532-cf driver calls gpio_direction_input(), the calls to rb532_gpio_set_func() and rb532_gpio_direction_input() are not needed since the alternate function is automatically being disabled when changing the GPIO pin direction. The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being done by the IRQ initialisation of pata-rb532-cf.

* MIPS: RB532: Auto disable GPIO alternate functionPhil Sutter2009-01-301-4/+4
| | | | | | | | | | When a driver calls gpio_set_direction_{input,output}(), it obviously doesn't want the alternate function for that pin to be active (as the direction would not matter in that case). This patch ensures alternate function is disabled when the direction is being changed. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: RB532: Add set_type() function to IRQ struct.Phil Sutter2009-01-302-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | Interrupt Group 4 mapps the GPIO pins enabled as interrupt sources; add defines to make this clear when addressing them later in code. The mapped GPIOs support triggering on either level high or low. To achieve this, the set_type() function calls rb532_gpio_set_ilevel() for interrupts of the above mentioned group. As there is no way to alter the triggering characteristics of the other interrupts, accept level triggering on status high only. (This is just a guess; but as the system boots fine and interrupt-driven devices (e.g. serial console) work with no implications, it seems to be right.) To clear a GPIO mapped IRQ, the source has to be cleared (i.e., the interrupt status bit of the corresponding GPIO pin). This is done inside rb532_disable_irq(). After applying these changes I could undo most of my former "fixes" to pata-rb532-cf. Particularly all interrupt handling can be done generically via set_irq_type() as it was before.

* Allow opportunistic merging of VM_CAN_NONLINEAR areasLinus Torvalds2009-01-301-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit de33c8db5910cda599899dd431cc30d7c1018cbf ("Fix OOPS in mmap_region() when merging adjacent VM_LOCKED file segments") unified the vma merging of anonymous and file maps to just one place, which simplified the code and fixed a use-after-free bug that could cause an oops. But by doing the merge opportunistically before even having called ->mmap() on the file method, it now compares two different 'vm_flags' values: the pre-mmap() value of the new not-yet-formed vma, and previous mappings of the same file around it. And in doing so, it refused to merge the common file case, which adds a marker to say "I can be made non-linear". This fixes it by just adding a set of flags that don't have to match, because we know they are ok to merge. Currently it's only that single VM_CAN_NONLINEAR flag, but at least conceptually there could be others in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code to support journal-less ext4 operation added a BUG to ext4_bmap() which fired if there was no journal and the EXT4_STATE_JDATA bit was set in the i_state field. This caused running the filefrag program (which uses the FIMBAP ioctl) to trigger a BUG(). The EXT4_STATE_JDATA bit is only used for ext4_bmap(), and it's harmless for the bit to be set. We could add a check in __ext4_journalled_writepage() and ext4_journalled_write_end() to only set the EXT4_STATE_JDATA bit if the journal is present, but that adds an extra test and jump instruction. It's easier to simply remove the BUG check. http://bugzilla.kernel.org/show_bug.cgi?id=12568 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: stable@kernel.org

| * ext4: only use i_size_high for regular filesTheodore Ts'o2009-01-172-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Directories are not allowed to be bigger than 2GB, so don't use i_size_high for anything other than regular files. E2fsck should complain about these inodes, but the simplest thing to do for the kernel is to only use i_size_high for regular files. This prevents an intentially corrupted filesystem from causing the kernel to burn a huge amount of CPU and issuing error messages such as: EXT4-fs warning (device loop0): ext4_block_to_path: block 135090028 > max Thanks to David Maciejak from Fortinet's FortiGuard Global Security Research Team for reporting this issue. http://bugzilla.kernel.org/show_bug.cgi?id=12375 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: stable@kernel.org

This patch workarounds the issue by enabling wakeup in the MDIO device, i.e. just restores the old behaviour for the gianfar driver. Note that this way all PHYs on a given MDIO bus won't be turned off during suspend, which isn't good from the power saving point of view. A proper, per netdevice wakeup management support will need a bit reworked phylib suspend/resume logic. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

| * | | smsc9420: fix interrupt signalling test failuresSteve Glendinning2009-01-291-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smsc9420 performs an interrupt signalling test when the interface is brought up. The current code mistakenly sets its test flag to false AFTER enabling the software interrupt source, making failure quite likely. This patch changes the code to set the test flag BEFORE enabling interrupts. I've also removed an smp_wmb because the following spinlock provides an implicit memory barrier.
