2007-02-12[PATCH] remove the broken FB_S3TRIO driverAdrian Bunk
The FB_S3TRIO driver: - has been marked as BROKEN for more than two years and - is still marked as BROKEN. Drivers that had been marked as BROKEN for such a long time seem to be unlikely to be revived in the forseeable future. But if anyone wants to ever revive this driver, the code is still present in the older kernel releases.

2007-02-12[PATCH] Workaround CAPI subsystem locking issueMichael Buesch
I think the following patch should go into the kernel, until the ISDN/CAPI guys create the real fix for this issue. The issue is a concurrency issue with some internal CAPI data structure which can crash the kernel. On my FritzCard DSL with the AVM driver it crashes about once a day without this workaround patch. With this workaround patch it's rock-stable (at least on UP, but I don't see why this shouldn't work on SMP as well. But maybe I'm missing something.) This workaround is kind of a sledgehammer which inserts a global lock to wrap around all the critical sections. Of course, this is a scalability issue, if you have many ISDN/CAPI cards. But it prevents a crash. So I vote for this fix to get merged, until people come up with a better solution. Better have a stable kernel that's less scalable, than a crashing and useless kernel. This bug is in the kernel since 2.6.15 (at least).

2007-02-12[PATCH] EDAC: Add memory scrubbing controls API to coreFrithiof Jensen
This is an attempt of providing an interface for memory scrubbing control in EDAC. This patch modifies the EDAC Core to provide the Interface for memory controller modules to implment. The following things are still outstanding: - K8 is the first implemenation, The patch provide a method of configuring the K8 hardware memory scrubber via the 'mcX' sysfs directory. There should be some fallback to a generic scrubber implemented in software if the hardware does not support scrubbing. Or .. the scrubbing sysfs entry should not be visible at all. - Only works with SDRAM, not cache, The K8 can scrub cache and l2cache also - but I think this is not so useful as the cache is busy all the time (one hopes). One would also expect that cache scrubbing requires hardware support. - Error Handling, I would like that errors are returned to the user in "terms of file system". - Presentation, I chose Bandwidth in Bytes/Second as a representation of the scrubbing rate for the following reasons: I like that the sysfs entries are sort-of textual, related to something that makes sense instead of magical values that must be looked up. "My People" wants "% main memory scrubbed per hour" others prefer "% memory bandwidth used" as representation, "bandwith used" makes it easy to calculate both versions in one-liner scripts. If one later wants to scrub cache, the scaling becomes wierd for K8 changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to "blocks of 64 bit". Using "bandwidth used" makes sense in all three cases, (I.M.O. anyway ;-). - Discovery, There is no way to discover the possible settings and what they do without reading the code and the documentation. *I* do not know how to make that work in a practical way. - Bugs(??), other tools can set invalid values in the memory scrub control register, those will read back as '-1', requiring the user to reset the scrub rate. This is how *I* think it should be. - Afflicting other areas of code, I made changes to edac_mc.c and edac_mc.h which will show up globally - this is not nice, it would be better that the memory scrubbing fuctionality and interface could be entirely contained within the memory controller it applies to. Frithiof Jensen edac_mc.c and its .h file is a CORE helper module for EDAC driver modules. This provides the abstraction for device specific drivers.

2007-02-12[PATCH] EDAC: e752x byte access fixBrian Pomerantz
The reading of the DRA registers should be a byte at a time (one register at a time) instead of 4 bytes at a time (four registers). Reading a dword at a time retrieves erroneous information from all but the first register. A change was made to read in each register in a loop prior to using the data in those registers.

2007-02-12[PATCH] EDAC: e752x bit mask fixBrian Pomerantz
The fatal vs. non-fatal mask for the sysbus FERR status is incorrect according to the E7520 datasheet. This patch corrects the mask to correctly handle fatal and non-fatal errors.

2007-02-12[PATCH] tty: update the tty layer to work with struct pidEric W. Biederman
Of kernel subsystems that work with pids the tty layer is probably the largest consumer. But it has the nice virtue that the assiation with a session only lasts until the session leader exits. Which means that no reference counting is required. So using struct pid winds up being a simple optimization to avoid hash table lookups. In the long term the use of pid_nr also ensures that when we have multiple pid spaces mixed everything will work correctly. Signed-off-by: Eric W.
