sgi-xpc: XPC fails to discover partitions with all nasids above 128

2010-12-14T22:40:07+00:00

commit c22c7aeff69796f46ae0fcec141538e28f50b24e upstream. UV hardware defines 256 memory protection regions versus the baseline 64 with increasing size for the SN2 ia64. This was overlooked when XPC was modified to accomodate both UV and SN2. Without this patch, a user could reconfigure their existing system and suddenly disable cross-partition communications with no indication of what has gone wrong. It also prevents larger configurations from using cross-partition communication.

drivers/misc/ad525x_dpot.c: fix typo in spi write16 and write24 transfer counts

2010-12-14T22:40:06+00:00

commit 1f9fa5216eacf4fdf9d3e4ab57feb8b642f0e78b upstream. This is a bug fix. Some SPI connected devices using 16/24 bit accesses, previously failed, now work. This typo slipped in after testing, during some restructuring.

sgi-xp: incoming XPC channel messages can come in after the channel's partition structures have been torn down

2010-11-22T19:00:17+00:00

commit 09358972bff5ce99de496bbba97c85d417b3c054 upstream. Under some workloads, some channel messages have been observed being delayed on the sending side past the point where the receiving side has been able to tear down its partition structures. This condition is already detected in xpc_handle_activate_IRQ_uv(), but that information is not given to xpc_handle_activate_mq_msg_uv(). As a result, xpc_handle_activate_mq_msg_uv() assumes the structures still exist and references them, causing a NULL-pointer deref.

vmware balloon: clamp number of collected non-balloonable pages

2010-06-04T22:21:44+00:00

Limit number of accumulated non-balloonable pages during inflation cycle, otherwise there is a chance we will be spinning and growing the list forever. This happens during torture tests when balloon target changes while we are in the middle of inflation cycle and monitor starts refusing to lock pages (since they are not needed anymore).

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58+00:00

I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

lktdm: add support for hardlockup, softlockup and hung task crashes

2010-05-27T16:12:54+00:00

This adds three new types of kernel "crashes" in the lkdtm driver to trigger hardlockups, softlockups and task hung states at will. The first two are useful to test the new generic lockup detector and check its further regressions. The latter one is a bonus to check the hung task detector regressions even though it's not currently in rework.
