2011-03-17mmc: core: reset card voltage after power offUlf Hansson
At power off, reset OCR mask to be the highest possible voltage supported for the current mmc host. This solves the re-initialization during the power up sequence. The voltage may have been decreased due to the card accepts a lower voltage than the voltage used during the initialization sequence. We need to reset the voltage to by the host highest possible value since according to specification the initialization must always be done at high voltage.

2011-03-17mmc: core: export function mmc_do_release_host()Ulf Hansson
When using mmc_try_claim_host the corresponding release function is mmc_do_release_host, which then also must be exported.

2011-03-17mmc: sdio: remember new card RCA when redetecting cardStefan Nilsson XK
During redetection of a SDIO card, a request for a new card RCA was submitted to the card, but was then overwritten by the old RCA. This caused the card to be deselected instead of selected when using the incorrect RCA. This bug's been present since the "oldcard" handling was introduced in 2.6.32.

2011-03-17mm: export __get_user_pagesHuang Ying
In most cases, get_user_pages and get_user_pages_fast should be used to pin user pages in memory. But sometimes, some special flags except FOLL_GET, FOLL_WRITE and FOLL_FORCE are needed, for example in following patch, KVM needs FOLL_HWPOISON. To support these users, __get_user_pages is exported directly. There are some symbol name conflicts in infiniband driver, fixed them too.
