2013-09-02ARM: 7829/1: Add ".text.unlikely" and ".text.hot" to arm unwind tablesDouglas Anderson2-0/+10
It appears that gcc may put some code in ".text.unlikely" or ".text.hot" sections. Right now those aren't accounted for in unwind tables. Add them. I found some docs about this at: http://gcc.gnu.org/onlinedocs/gcc-4.6.2/gcc.pdf Without this, if you have slub_debug turned on, you can get messages that look like this: unwind: Index not found 7f008c50 Signed-off-by: Doug Anderson <dianders@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2013-08-29ASoC: Samsung: Do not queue cyclic buffers multiple timesTomasz Figa1-2/+11
The legacy S3C-DMA API required every period of a cyclic buffer to be queued separately. After conversion of Samsung ASoC to Samsung DMA wrappers somebody made an assumption that the same is needed for DMA engine API, which is not true. In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer multiple times with a shift of one period per iteration, leading to: a) severe memory waste - up to 13x times more DMA transfer descriptors are allocated than needed, b) possible memory corruption, because further cyclic buffers were out of the original buffers, due to the offset. This patch fixes this problem by making the legacy S3C-DMA API use the same semantics as DMA engine (the whole cyclic buffer is enqueued at once) and modifying users of Samsung DMA wrappers in cyclic mode to behave appropriately.

2013-08-29OMAPDSS: fix DPI and SDI device idsTomi Valkeinen1-2/+2
The DPI and SDI platform devices are currently created with the ID of -1. The ID doesn't currently affect anything. However, we have added regulator supply entries for "omapdss_dpi.0" and "omapdss_sdi.0" to the board files, although these supply entries are not yet used. As the ID used for the devices is -1, these regulator supply entries will not work. To fix the issue, assign ID of 0 to the devices. In the future there may be more than one DPI or SDI output, so it makes sense to have a proper ID for them.

Let's follow the ratified DT binding and use uartdm instead of hsuart. This does break backwards compatibility but this shouldn't be a problem because the uart driver isn't probing on these devices without adding clock support (which isn't merged so far).

2013-08-28ARM: vexpress: tc2: disable GIC CPU IF in tc2_pm_suspendLorenzo Pieralisi1-0/+2
To prevent cores from exiting wfi when they are about to be shut down the GIC CPU IF must be disabled so that the GIC CPU IF IRQ output line is not asserted to the cores. wfi completion must be prevented since, in absence of coordinating HW logic, if the power controller receives a standbywfi signal but in the meantime the processor restarts executing owing to a pending IRQ, the core might be reset when running in a non-quiescent state (eg with pending load/store transactions) Raw GIC distributor IRQ signals are routed to the power controller, that is capable of taking core out of reset on pending IRQs even if their GIC CPU IF is disabled, thus keeping the normal wfi behaviour. GIC CPU IF is restored upon CPU wake-up by the respective MCPM API consumers (ie CPU idle driver and suspend to RAM thread).
