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.

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: NIan Molton <ian@mnementh.co.uk> Signed-off-by: NPierre Ossman <pierre@ossman.eu>

The Toshiba parts all have a 24 MHz HCLK, but HTC ASIC3 has a 24.576 MHz HCLK and AMD Imageon w228x's HCLK is 80 MHz.

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.

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.

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.

For this purpose it is convenient to move swsusp_shrink_memory() from kernel/power/swsusp.c to kernel/power/snapshot.c, because the new memory-shrinking code is going to use things that are local to kernel/power/snapshot.c .
