The patch "dw_mmc: fix multiple drv_data NULL dereferences" has unfortunately clashed with my "mmc: dw_mmc: constify dw_mci_idmac_ops in exynos back-end" patch, causing new warnings to appear. This should hopefully fix the issue for good. Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NChris Ball <cjb@laptop.org>

When a SD card is initialized some data transfers of 64 and 8 bytes are issued. It seems the DMA has some problems dealing with these kind of "short" transfers, leading sometimes to the SD card not being detected. In order to solve this problem, do not use DMA for transfer sizes lower than the sector size.

The vmmc regulator enable in sdhci_add_host is NOT necessary since it can be enabled during mmc_power_up by function mmc_regulator_set_ocr. And this extra enable will make regulator_enable/regulator_disable unbalanced. Consequently, vmmc can't be disabled during mmc_power_off. Also, if the vqmmc regulator exists, it should be enabled regardless it support 1.8v or not.

There are two problems here: The check for vmmc was printing an unnecessary pr_info() when host->vmmc is NULL. The intent of the check for vqmmc was to only remove UHS if we have a regulator that doesn't support the required voltage, but since IS_ERR() doesn't catch NULL, we were actually removing UHS modes if vqmmc isn't present at all -- since it isn't present for most users, this breaks UHS for them. This patch fixes that UHS regression in 3.7-rc1.

The hostprogs need access to the CONFIG_* symbols found in include/generated/autoconf.h. But commit abbf1590 ("UAPI: Partition the header include path sets and add uapi/ header directories") replaced $(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary include paths. This has the undesirable effect of breaking the EFI boot stub because the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is never compiled. It should also be noted that because $(USERINCLUDE) isn't exported by the top-level Makefile it's actually empty in arch/x86/boot/Makefile. Cc: H.

Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells: "The patches contained herein do the following: (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked this with Paul Mackerras before I created the patch and he suggested some extra bits to unexport. (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace applicable, and remove from the UAPI that part of linux/fs.h that was the reason for linux/blk_types.h being exported in the first place. I discussed this with Jens Axboe before creating the patch. (3) The big patch of the series to disintegrate include/linux/*.h as a unit. This could be split up, though there would be collisions in moving stuff between the two Kbuild files when the parts are merged as that file is sorted alphabetically rather than being grouped by subsystem. Of this set of headers, 17 files have changed in the UAPI exported region since the 4th and only 8 since the 9th so there isn't much change in this area - as one might expect. It should be pretty obvious and straightforward if it does come to fixing up: stuff in __KERNEL__ guards stays where it is and stuff outside moves to the same file in the include/uapi/linux/ directory. If a new file appears then things get a bit more complicated as the "headers +=" line has to move to include/uapi/linux/Kbuild. Only one new file has appeared since the 9th and I judge this type of event relatively unlikely. (4) A patch to disintegrate include/linux/byteorder/*.h as a unit.
