2012-10-23Btrfs: fix a tree mod logging issue for root replacement operationsJan Schmidt1-8/+2
Avoid the implicit free by tree_mod_log_set_root_pointer, which is wrong in two places. Where needed, we call tree_mod_log_free_eb explicitly now. Signed-off-by: Jan Schmidt <[email protected]>
2012-10-23Btrfs: don't put removals from push_node_left into tree mod log twiceJan Schmidt1-2/+7
Independant of the check (push_items < src_items) tree_mod_log_eb_copy did log the removal of the old data entries from the source buffer. Therefore, we must not call tree_mod_log_eb_move if the check evaluates to true, as that would log the removal twice, finally resulting in (rewinded) buffers with wrong values for header_nritems.

2012-10-23spi/pl022: Revert recent runtime PM changesUlf Hansson1-3/+0
[Originally sent by Ulf as two changes, squashed down into one with a redone changelog, thanks to Russell King for analysis. -- broonie] This reverts commit 688723 (spi/pl022: enable runtime PM) and commit 2fb30d (spi/pl022: fix spi-pl022 pm enable at probe). Commit "spi/pl022: enable runtime PM" introduced runtime PM issues as it interacted badly with the work Russell King had done to move core runtime PM handling into the bus. Due to that commit, "spi/pl022: fix spi-pl022 pm enable at probe" was merged to fix part of those issues. Instead of adding another fix, let's clean up and revert everything back to when it was already fine.

The irqdomain semantics were supposed to be such that a linear domain would be used if the passed first_irq was zero or negative, but I got it wrong so only passing zero as first_irq will work properly.

2012-10-23pinctrl/nomadik: use irq_create_mapping()Linus Walleij1-1/+1
Since in the DT case, the linear domain path will not allocate descriptors for the IRQs, we need to use irq_create_mapping() for mapping hwirqs to Linux IRQs, so these descriptors get created on-the-fly in this case. ChangeLog v1->v2: - Just use irq_create_mapping() in the .to_irq function since this is called before unmasking or enabling any interrupt lines, so irq_find_mapping() should be sufficient for the IRQ handler function.

2012-10-23extcon : register for cable interest by cable nameJenny TC1-10/+34
There are some scnearios where a driver/framework needs to register interest for a particular cable without specifying the extcon device name. One such scenario is charger notifications. The platform will have charger cabel which will be bound to any extcon device. It's not mandatory for the charger driver to know which extcon device it should use.

2012-10-23tcp: Reject invalid ack_seq to Fast Open socketsJerry Chu2-4/+12
A packet with an invalid ack_seq may cause a TCP Fast Open socket to switch to the unexpected TCP_CLOSING state, triggering a BUG_ON kernel panic. When a FIN packet with an invalid ack_seq# arrives at a socket in the TCP_FIN_WAIT1 state, rather than discarding the packet, the current code will accept the FIN, causing state transition to TCP_CLOSING. This may be a small deviation from RFC793, which seems to say that the packet should be dropped. Unfortunately I did not expect this case for Fast Open hence it will trigger a BUG_ON panic. It turns out there is really nothing bad about a TFO socket going into TCP_CLOSING state so I could just remove the BUG_ON statements. But after some thought I think it's better to treat this case like TCP_SYN_RECV and return a RST to the confused peer who caused the unacceptable ack_seq to be generated in the first place.

2012-10-23pch_gbe: don't reset MAC_RX on FIFO overflowVeaceslav Falico1-60/+6
Currently, when FIFO_ERR happens, we stop the dma, wait for it to become idle and then reset the whole MAC_RX logic (and after that we must re-set multicast addresses and also re-enable MAC_RX when we're finally ready to accept new packets). This leads to CRC errors on high number of incoming packets and is not needed according to the datasheet. This patch fixes it by the following steps: 1) remove this reset in pch_gbe_stop_receive(), which causes some functions to not be used anywhere 2) remove already unused functions pch_gbe_wait_clr_bit_irq() and pch_gbe_mac_reset_rx() to correctly build 3) move pch_gbe_enable_mac_rx() out of pch_gbe_start_receive() to pch_gbe_up() where it's only needed after we've removed the MAC_RX reset 4) rename pch_gbe_start/stop_receive() to pch_gbe_enable/disable_dma_rx() to more precisely reflect what the functions are now doing. After these changes we already don't see the CRC errors and gain some increase in RX processing speed. Signed-off-by: Veaceslav Falico <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-10-23pch_gbe: don't re-set RX_FIFO_ERR flag in napi_pollVeaceslav Falico1-13/+6
If we were in RX_FIFO_ERR state and entered pch_gbe_napi_poll(), we'll anyway clean some rx space and thus can continue to receive more packets. Currently, we re-set the RX_FIFO_ERR in situations when we've exhausted our budget for RX cleaning or cleaned some TX packets. Removing it gives us +20%-40% speed increase and a lot less of RX_FIFO_ERRors reported. Signed-off-by: Veaceslav Falico <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2012-10-23drm/ttm: Fix a theoretical race in ttm_bo_cleanup_refs()Thomas Hellstrom1-8/+12
In theory, that function could release the lru lock between checking for bo on ddestroy list and a successful reserve if the bo was already reserved, and the function was called with waiting reserves allowed. However, all current reservers of a bo on the ddestroy list would atomically take the bo off the list after a successful reserve so this race should not have been hit, so no need to backport for stable. This patch also fixes a case found by Maarten Lankhorst where ttm_mem_evict_first called with no_wait_gpu would incorrectly spin waiting for bo idle if trying to evict a busy buffer that also sits on the ddestroy list.

2012-10-22ARM: OMAP3: Beagle: fix OPP customization and initcall orderingKevin Hilman1-9/+13
After commit 24d7b40a60cf19008334bcbcbd98da374d4d9c64 (ARM: OMAP2+: PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered using an existing CPU device, not the omap_device for MPU-SS. First, fix the board file to use get_cpu_device() as required by the above commit, otherwise custom OPPs will be added to the wrong device. Second, the board files OPP init is called from the its init_machine method, and the generic CPU devices are not yet created when init_machine is run. Therefore OPP initialization will fail. To fix, use a device_initcall() for the board file's OPP customization, and make the device_initcall board-specific by using a machine_is check.

2012-10-23ACPI: Fix memory leak in acpi_bind_one()Jesper Juhl1-0/+1
Memory is allocated with kzalloc() and assigned to 'physical_node'. Then 'physical_node->node_id' is initialized with a call to 'find_first_zero_bit()', if that results in a value greater than ACPI_MAX_PHYSICAL_NODE we'll end up jumping to the 'err:' label and there leave the function and let 'physical_node' go out of scope and leak the memory we allocated. This patch fixes the leak by simply freeing the unused/unneeded memory pointed to by 'physical_node' just before we jump to 'err:'.
