* mmc: mxcmmc: use dmaengine APISascha Hauer2011-03-15
| | | | | | | | | | | | This switches the mxcmmc driver to use the dmaengine API. Unlike the old one this one is always present in the tree, even if no DMA is implemented, hence we can remove all the #ifdefs in from the driver. The driver automatically switches to PIO mode if no DMA support or no suitable channel is available.

| | | | | | | | | | | | | If we need some quirks, maybe add quirks in future But now, quirks value set to integer..later we should be confused.. So I think that need bit-shift control.

* mmc: export eMMC4.4 enhanced area details to sysfsChuanxiao Dong2011-03-15
| | | | | | | | | | | | | | | | | | Enhanced area feature is a new feature defined in eMMC4.4 standard. This user data area provides higher performance/reliability, at the expense of using twice the effective media space due to the area using SLC. The MMC driver now reads out the enhanced area offset and size and adds them to the device attributes in sysfs. Enabling the enhanced area can only be done once, and should be done in manufacturing. To use this feature, bit ERASE_GRP_DEF should also be set. Documentation/ABI/testing/sysfs-devices-mmc describes the two new attributes.

The intention was to only skip detection of hardwired cards that cannot be removed, so make sure this is indeed the case by directly checking for (lack of) MMC_CAP_NONREMOVABLE, instead of using mmc_card_is_removable(), which is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. The user-visible symptom of the bug this patch fixes is that no "mmc: card XXXX removed" message appears in dmesg when a card is removed and CONFIG_MMC_UNSAFE_RESUME=y.

Fortunately, it's enough to make freeing that sucker delayed, provided that we don't step on its ->unregistering, clear the pointer to it in PROC_I(inode) before dropping the reference and check if it's NULL in ->d_compare(). b) I'm not sure that we *can* walk into NULL inode here (we recheck dentry->seq between verifying that it's still hashed / fetching dentry->d_inode and passing it to ->d_compare() and there's no negative hashed dentries in /proc/sys/*), but if we can walk into that, we really should not have ->d_compare() return 0 on it!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | failure exits on the no-O_CREAT side of do_filp_open() merge with those of O_CREAT one; unfortunately, if do_path_lookup() returns -ESTALE, we'll get out_filp:, notice that we are about to return -ESTALE without having trying to create the sucker with LOOKUP_REVAL and jump right into the O_CREAT side of code. And proceed to try and create a file. Usually that'll fail with -ESTALE again, but we can race and get that attempt of pathname resolution to succeed. open() without O_CREAT really shouldn't end up creating files, races or not. The real fix is to rearchitect the whole do_filp_open(), but for now splitting the failure exits will do. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
