2009-06-15ps3vram: Replace mutex by spinlock + bio_listGeert Uytterhoeven
Remove the mutex serializing access to the cache. Instead, queue up new requests on a bio_list if the driver is busy. This improves sequential write performance by ca. 2%.

2009-06-15ps3fb: Tear down FB setup during cleanupGeert Uytterhoeven
During cleanup, use L1GPU_CONTEXT_ATTRIBUTE_FB_CLOSE to tear down the setup done by L1GPU_CONTEXT_ATTRIBUTE_FB_SETUP. This allows unloading and reloading of ps3fb while the sound driver keeps the GPU open.

This patch fixes the clock setup in tmio_mmc. * Incorrect divider setting * Cruft written to the clock registers (seemingly harmless but Not Good (tm)) It also eliminates some unnecessary ifs and tidies the loop syntax. Thanks to Philipp Zabel who discovered the divider issue, commenting "Except for the SDCLK = HCLK (divider bypassed) case, the clock setting resulted in double the requested frequency.

2009-06-13mmc/omap: make mmci-omap using platform_driver_probeUwe Kleine-König
A pointer to mmc_omap_probe which lives in .init.text is passed to the core via platform_driver_register and so the kernel might oops if probe is called after the init code is discarded. As requested by David Brownell platform_driver_probe is used instead of moving the probe function to .devinit.text. This saves some memory, but might have the downside that a device being registered after the call to mmc_omap_init but before the init sections are discarded will not be bound anymore to the driver.

2009-06-13mmc: mmc_rescan detects card change in one runJorg Schummer
With this patch, mmc_rescan can detect the removal of an mmc card and the insertion of (possibly another) card in the same run. This means that a card change can be detected without having to call mmc_detect_change multiple times. This change generalises the core such that it can be easily used by hosts which provide a mechanism to detect only the presence of a card reader cover, which has to be taken off in order to insert a card. Other hosts ("card detect" or "MMC_CAP_NEEDS_POLL") each receive an event when a card is removed and when a card is inserted, so it is sufficient for them if mmc_rescan handles only one event at a time. "Cover detect" hosts, however, only receive events about the cover status. This means that between 2 subsequent events, both a card removal and a card insertion can occur. In this case, the pre-patch version of mmc_rescan would only detect the removal of the previous card but not the insertion of the new card.
