[PATCH] AFS: Fix possible null pointer dereference in afs_alloc_server()
From: Denis Kirjanov <dkirjanov(a)hera.kernel.org> Fix a possible null pointer dereference in afs_alloc_server(): the server pointer is NULL if there was an allocation failure, and under such a condition, we can't dereference it in the _leave() statement.

Documentation/timers/hpet_example.c: only build on X64

[PATCH 8/8] edac, mc: Improve scrub rate handling
Fortify the interface to not accept negative values, remove memctrl_int_store() as a result. Also, sanitize bandwidth setting by making the argument a simple u32 instead of strange u32 pointer being passed around for no obvious reason. Then, fix error handling and teach it to return proper error values. Finally, ma... 1 Jun 2010 11:58

Changes from v2: added padding between avail idx and flags, and changed virtio to only publish used index when callbacks are enabled. Here's a rewrite of the original patch with a new layout. I haven't tested it yet so no idea how this performs, but I think this addresses the cache bounce issue raised by Avi. P... 1 Jun 2010 11:58
