2009-06-13mmc_block: do not DMA to stackBen Dooks
In the write recovery routine, the data to get from the card is allocated from the stack. The DMA mapping documentation says explicitly stack memory is not mappable by any of the DMA calls. Change to using kmalloc() to allocate the memory for the result from the card and then free it once we've finished with the transaction.

2009-06-13tmio_mmc: fix clock setupIan Molton
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. The smallest possible frequency (f_max/512) is configured with a divider setting 0x80, not 0x40." Signed-off-by: Ian Molton <ian@mnementh.co.uk> Signed-off-by: Pierre Ossman <pierre@ossman.eu>

2009-06-13mmc_spi: don't use EINVAL for possible transmission errorsWolfgang Muees
This patch changes the reported error code for the responses to a command from EINVAL to EFAULT/ENOSYS, as EINVAL is reserved for non-recoverable host errors, and the responses from the SD/MMC card may be because of recoverable transmission errors in the command or in the response. Response codes in SPI mode are NOT protected by a checksum, so don't trust them.

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.

2009-06-12Driver Core: Rework platform suspend/resume, print warningMagnus Damm
This patch reworks the platform driver code for legacy suspend and resume to avoid installing callbacks in struct device_driver. A warning is also added telling users to update the platform driver to use dev_pm_ops. The functions platform_legacy_suspend()/resume() directly call suspend and resume callbacks in struct platform_driver instead of wrapping things in platform_drv_suspend()/resume().

2009-06-12PM core: rename suspend and resume functionsAlan Stern
This patch (as1241) renames a bunch of functions in the PM core. Rather than go through a boring list of name changes, suffice it to say that in the end we have a bunch of pairs of functions: device_resume_noirq dpm_resume_noirq device_resume dpm_resume device_complete dpm_complete device_suspend_noirq dpm_suspend_noirq device_suspend dpm_suspend device_prepare dpm_prepare in which device_X does the X operation on a single device and dpm_X invokes device_X for all devices in the dpm_list. In addition, the old dpm_power_up and device_resume_noirq have been combined into a single function (dpm_resume_noirq). Lastly, dpm_suspend_start and dpm_resume_end are the renamed versions of the former top-level device_suspend and device_resume routines.

2009-06-12PM: Rename device_power_down/up()Magnus Damm
Rename the functions performing "_noirq" dev_pm_ops operations from device_power_down() and device_power_up() to device_suspend_noirq() and device_resume_noirq(). The new function names are chosen to show that the functions are responsible for calling the _noirq() versions to finalize the suspend/resume operation. The current function names do not perform power down/up anymore so the names may be misleading. Global function renames: - device_power_down() -> device_suspend_noirq() - device_power_up() -> device_resume_noirq() Static function renames: - suspend_device_noirq() -> __device_suspend_noirq() - resume_device_noirq() -> __device_resume_noirq() Signed-off-by: Magnus Damm <damm@igel.co.jp> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Acked-by: Len Brown <lenb@kernel.org> Signed-off-by: Rafael J.

2009-06-12lguest: use eventfds for device notificationRusty Russell
Currently, when a Guest wants to perform I/O it calls LHCALL_NOTIFY with an address: the main Launcher process returns with this address, and figures out what device to run.
