* [PATCH] mmc (mainly): add "or later" clause to licence statement.Pierre Ossman2006-10-01
| | | | | | | | | | | | Clarify my (Pierre's) position on which GPL versions apply. The patch only touches the source files where I am the only major author. The people who have made the minor commits to the files have been contacted and have no issues with this change.

* [PATCH] BLOCK: Make it possible to disable the block layer [try #6]David Howells2006-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen.

* [PATCH] Split struct request ->flags into two partsJens Axboe2006-09-30
| | | | | | | | | | Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>

| * | [MMC] MMC_CAP_BYTEBLOCK flag for non-log2 block sizes capable hostsRussell King2006-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some MMC hosts can only handle log2 block sizes. Unfortunately, the MMC password support needs to be able to send non-log2 block sizes. Provide a capability so that the MMC password support can decide whether it should use this support or not. The unfortunate side effect of this host limitation is that any MMC card protected by a password which is not a log2 block size can not be accessed on a host which only allows a log2 block size. This change just adds the flag. The MMC password support code needs updating to use it (if and when it is finally submitted.) Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The last point is very important - if a driver reports more bytes than were actually accepted by the card and an error occurs, there is the possibility for data loss.

* [MMC] Always use a sector size of 512 bytesPierre Ossman2006-09-07
| | | | | | | | | | | | | Both MMC and SD specifications specify (although a bit unclearly in the MMC case) that a sector size of 512 bytes must always be supported by the card. Cards can report larger "native" size than this, and cards >= 2 GB even must do so. Most other readers use 512 bytes even for these cards. We should do the same to be compatible.

| | | | | | | | | | | | | | | | Patch from Pavel Pisa This is another approach to SDHC deficiency workaround. It seems, that previous solution based on 16 bytes (FIFO length size) read is still timing sensitive on genirq and fully preemptive kernels. The new solution is backuped by M9328 UM statement, that only 512 byte block are working properly and by 2.4.26 FreeScale's SDHC code. Jay Monkman reports significant improvement on code based on this driver after applying this change on MX21 as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As sdhci is a generic driver, it is helpful to see some more specific identification of the actual hardware in dmesg. PCI vendor, device and revision is sufficient in most cases.

| * | [MMC] sdhci: check SDHCI base clockPierre Ossman2006-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | A base clock value of 0 means that the driver must get the base clock through some other means. As we have no other way of getting it, we must abort.
