2009-11-19ASoC: DaVinci: pcm, fix underrun by using sramTroy Kisky
Fix underruns by using dma to copy 1st to sram in a ping/pong buffer style and then copying from the sram to the ASP. This also has the advantage of tolerating very long interrupt latency on dma completion.

2009-11-18ARM: S3C64XX: Added platform data headerJassi Brar
Many SoCs have their I2S pins MUXed with other functions. So we need to pass a callback for driver to configure the pins appropriately. Hence, the need of platform data and this header. As and when needed new callbacks and structure pointers maybe added to this header.

2009-11-02ARM: ensure initial page tables are setup for SMP systemsRussell King
Mapping the same memory using two different attributes (memory type, shareability, cacheability) is unpredictable. During boot, we encounter a situation when we're updating the kernel's page tables which can lead to dirty cache lines existing in the cache which are subsequently missed. This causes stack corruption, and therefore a crash. Therefore, ensure that the shared and cacheability settings matches the configuration that will be used later; this together with the restriction in early_cachepolicy() ensures that we won't create a mismatch during boot.

2009-11-02MIPS: Alchemy: Fix hang with high-frequency edge interruptsManuel Lauss
The handle_edge_irq() flowhandler disables edge int sources which occur too fast (i.e. another edge comes in before the irq handler function had a chance to finish). Currently, the mask_ack() callback does not ack the edges in hardware, leading to an endless loop in the flowhandler where it tries to shut up the irq source. When I rewrote the alchemy IRQ code I wrongly assumed the mask_ack() callback was only used by the level flowhandler, hence it omitted the (at the time pointless) edge acks. Turned out I was wrong; so here is a complete mask_ack implementation for Alchemy IC, which fixes the above mentioned problem.

2009-11-02MIPS: Fix machine check exception in kmap_coherent()Kevin Cernekee
On an SMP system with cache aliases, the following sequence of events may happen: 1) copy_user_highpage() runs on CPU0, invoking kmap_coherent() to create a temporary mapping in the fixmap region 2) copy_page() starts on CPU0 3) CPU1 sends CPU0 an IPI asking CPU0 to run local_r4k_flush_cache_page() 4) CPU0 takes the interrupt, interrupting copy_page() 5) local_r4k_flush_cache_page() on CPU0 calls kmap_coherent() again 6) The second invocation of kmap_coherent() on CPU0 tries to use the same fixmap virtual address that was being used by copy_user_highpage() 7) CPU0 throws a machine check exception for the TLB address conflict Fixed by creating an extra set of fixmap entries for use in interrupt handlers. This prevents fixmap VA conflicts between copy_user_highpage() running in user context, and local_r4k_flush_cache_page() invoked from an SMP IPI.
