Support for the Secure Digital protocol in the MMC layer. A summary of the legal issues surrounding SD cards, as understood by yours truly: Members of the Secure Digital Association, hereafter SDA, are required to sign a NDA[1] before given access to any specifications. It has been speculated that including an SD implementation would forbid these members to redistribute Linux. This is the basic problem with SD support so it is unclear if it even is a problem since it has no effect on those of us that aren't members. The SDA doesn't seem to enforce these rules though since the patches included here are based on documentation made public by some of the members. The most complete specs[2] are actually released by Sandisk, one of the founding companies of the SDA. Because of this the NDA is considered a non-issue by most involved in the discussions concerning these patches. It might be that the SDA is only interested in protecting the so called "secure" bits of SD, which so far hasn't been found in any public spec. (The card is split into two sections, one "normal" and one "secure" which has an access scheme similar to TPM:s). (As a side note, Microsoft is working to make things easier for us since they want to be able to include the source code for a SD driver in one of their development kits. HP is making sure that the new NDA will allow a Linux implementation. So far only the SDIO specs have been opened up[3]. More will hopefully follow.)

If no MMC cards are found on a bus then the MMC layer proceeds looking for SD cards. Helper functions are extended to handle the special needs of SD cards. Signed-off-by:

This adds NLS support to HFS. Using the kernel options iocharset and codepage it's possible to map the disk encoding to a local mapping. If these options are not used, it falls back to the old direct mapping. Signed-off-by:

The IPMI power control function proc_write_chassctrl was badly written, it directly used userspace pointers, it assumed that strings were NULL terminated, and it used the evil sscanf function. This converts over to using the sysctl interface for this data and changes the semantics to be a little more logical. Signed-off-by:

This patch allows Dell servers with IPMI controllers that predate IPMI 1.5 to use the standard poweroff or powercycle commands. These systems firmware don't set the chassis capability bit in the Get Device ID, but they do implement the standard poweroff and powercycle commands. Tested on RHEL3 kernel 2.4.21-20.ELsmp on a PowerEdge 2600. The standard ipmi_poweroff driver cannot drive these systems. With this patch, they power off or powercycle as expected. Signed-off-by:

The "null message handler" in the IPMI driver is used in startup and panic situations to handle messages. It was only designed to work with messages from the local management controller, but in some cases it was used to get messages from remote managmenet controllers, and the system would then panic. This patch makes the "null message handler" in the IPMI driver more general so it works with any kind of message. Signed-off-by:

This adds MODULE_VERSION, MODULE_DESCRIPTION, and MODULE_AUTHOR tags to the IPMI driver modules. Also changes the MODULE_VERSION to remove the prepended 'v' on each value, consistent with the module versioning policy. This patch also removes all the version information from everything except the ipmi_msghandler module. Signed-off-by:

The ipmi driver does not have a way to handle firmware-generated events which have the OEM[012] Data Available flags set. In such a case, the SMS_ATN bit may never get cleared by firmware, leaving the driver looping infinitely but never able to make any progress. This patch first simplifies storage and use of the data returned from an IPMI Get Device ID command. It then creates a new per-OEM handler hook, which should know how to handle events with the OEM[012] Data Available flags set. It then uses this to implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which are susceptable to setting the OEM[012] Data Available flags when the driver can't handle it.

IPMI allows multiple IPMB channels on a single interface, and each channel might have a different IPMB address. However, the driver has only one IPMB address that it uses for everything. This patch adds new IOCTLS and a new internal interface for setting per-channel IPMB addresses and LUNs. New systems are coming out with support for multiple IPMB channels, and they are broken without this patch. Signed-off-by:

Background: 1) dmi_check_system() returns the count of the number of matches. Zero thus means no matches. 2) A match callback can return nonzero to stop the match checking. Bug: The count is incremented after we check for the nonzero return value, so it does not reflect the actual count. We could say this is intended, for some dumb reason, except that it means that a match on the first check returns zero--no matches--if the callback returns nonzero. Attached patch implements the count before calling the callback and thus before potentially short-circuiting. Signed-off-by:

cifs_create() did totally the wrong thing with nd->intent.open.flags: it interpreted nd->intent.open.flags as the original open flags, not the one transformed for open_namei(). Also it used the intent data even if it was not filled in (if called from sys_mknod()). Signed-off-by:
