2013-01-08drm/ttm: fix fence locking in ttm_buffer_object_transferDaniel Vetter1-1/+3
Noticed while reviewing the fence locking in the radeon pageflip handler. v2: Instead of grabbing the bdev->fence_lock in object_transfer just move the single callsite of that function a few lines, so that it is protected by the fence_lock. Suggested by Jerome Glisse. v3: Fix typo in commit message.

2013-01-07ARM: highbank: fix secondary boot and hotplugRob Herring2-12/+2
With commit 384a290 (ARM: gic: use a private mapping for CPU target interfaces), wake-up IPIs now go to all cores as the gic cpu interface numbering may not follow core numbering. This broke secondary boot on highbank since the boot address was already set for all secondary cores, this caused all cores to boot before the kernel was ready. Fix this by moving the setting of the jump address to highbank_boot_secondary instead of highbank_smp_prepare_cpus and highbank_cpu_die. Also, clear the address when we boot. This prevents cores from booting before they are actually triggered and is also necessary to get suspend/resume to work.

Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem makes memory leak. release function of dma-buf cannot be called because f_count of dma-buf increased by importing gem and gem ref count cannot be decrease because of exported dma-buf. So I add dma_buf_put() for imported gem come from its own gem into each drivers having prime_import and prime_export capabilities.

Since commit 8871e99f89b7 ('asus-laptop: HRWS/HWRS typo'), module initialisation is very slow on the Asus UL30A. The HWRS method takes about 12 seconds to run, and subsequent initialisation also seems to be delayed. Since we don't really need the result, don't bother calling it on init.

2013-01-07sctp: fix Kconfig bug in default cookie hmac selectionAlex Elder1-1/+1
Commit 0d0863b02002 ("sctp: Change defaults on cookie hmac selection") added a "choice" to the sctp Kconfig file. It introduced a bug which led to an infinite loop when while running "make oldconfig". The problem is that the wrong symbol was defined as the default value for the choice. Using the correct value gets rid of the infinite loop. Note: if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present in the generated config file.

After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering the "Device Drivers" toplevel menu in menuconfig, the suboptions behind EDAC appeared merged with the rest of the device drivers types. This was because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig bool which was defined after the menu definition.

2013-01-06tcp: fix MSG_SENDPAGE_NOTLAST logicEric Dumazet1-1/+3
commit 35f9c09fe9c72e (tcp: tcp_sendpages() should call tcp_push() once) added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all frags but the last one for a splice() call. The condition used to set the flag in pipe_to_sendpage() relied on splice() user passing the exact number of bytes present in the pipe, or a smaller one. But some programs pass an arbitrary high value, and the test fails. The effect of this bug is a lack of tcp_push() at the end of a splice(pipe -> socket) call, and possibly very slow or erratic TCP sessions. We should both test sd->total_len and fact that another fragment is in the pipe (pipe->nrbufs > 1) Many thanks to Willy for providing very clear bug report, bisection and test programs.

When a channel fails to initialize, we release all ressources, including clocks. However, a XOR unit is not necessarily associated to a clock (some variants of Marvell SoCs have a clock for XOR units, some don't), so we shouldn't unconditionally be releasing the clock. Instead, just like we do in the mv_xor_remove() function, we should check if one clock was found before releasing it.

2013-01-06dma: mv_xor: fix error handling of mv_xor_channel_add()Thomas Petazzoni1-1/+1
When mv_xor_channel_add() fails for one XOR channel, we jump to the err_channel_add label to clean up all previous channels that had been initialized correctly. Unfortunately, while handling this error condition, we were disposing the IRQ mapping before calling mv_xor_channel_remove() (which does the free_irq()), which is incorrect. Instead, do things properly in the reverse order of the initialization: first remove the XOR channel (so that free_irq() is done), and then dispose the IRQ mapping. This avoids ugly warnings when for some reason one of the XOR channel fails to initialize.

2013-01-06arm: mvebu: Armada XP MV78230 has only three Ethernet interfacesThomas Petazzoni3-8/+16
We originally thought that the MV78230 variant of the Armada XP had four Ethernet interfaces, like the other variants MV78260 and MV78460. In fact, this is not true, and the MV78230 has only three Ethernet interfaces. So, the definitions of the Ethernet interfaces is now done as follows: * armada-370-xp.dtsi: definitions of the first two interfaces, that are common to Armada 370 and Armada XP * armada-xp.dtsi: definition of the third interface, common to all Armada XP variants. * armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of the fourth interface.

2013-01-06arm: mvebu: Armada XP MV78230 has two cores, not oneThomas Petazzoni1-0/+7
Contrary to our understanding at the time armada-xp-mv78230.dtsi was written, the MV78230 variant of the Armada XP SoC has two cores and not one. This patch updates the .dtsi file to take into account this reality.

2013-01-06clk: mvebu: Remove inappropriate __init taggingJoshua Coombs1-1/+1
If the Orion WDT driver is built as a module, an opps occurs during clk lookup when calling mvebu_clk_gating_get_src(). Remove the inappropriate __init tag so the function is available for modules after kernel init.
